Touareg 2006-2010

The second generation Touareg made its debut at the Paris Motor Show in September 2006 and launched in the UK in January 2007.  Building on the success of the first generation model, the new Touareg exhibits some significant technical updates including ABSplus, rollover protection, and an optional trailer stabilisation system.  External design updates accompany the changes below the skin. 

Volkswagen’s first venture into the luxury 4x4 market was led by the Touareg (launched in Spring 2003), a model that remains one of the most sophisticated vehicles in its segment.  It combines true off-road ability with the comfort and refinement of a luxury saloon.

Starting with a clean sheet, the Touareg is designed to deliver class-leading performance both on and off the road.  Features such as permanent four-wheel drive, low and high gear ratios, electronic traction control linked to an auto-locking centre differential, hill start and descent assist, a rollover sensor and short front and rear overhangs all contribute to class-leading capability when venturing off the beaten track.  Versions with air suspension with the benefit of automatic and manual height adjustment have enhanced off-road ability and can ford depths of up to 580 mm.  On the road, the Touareg benefits from a host of electronic driver aids, such as enhanced ABS, brake assist and ESP (Electronic Stabilisation Programme).  The revised system incorporates Active Rollover Protection (ARP), rain brake support, fading brake support and understeer control logic which sharpens the Touareg’s turning behaviour through a corner.

The latest model also debuts Volkswagen’s pioneering braking system – ABSplus.  This works in conjunction with the Touareg’s ABS linked to 330 mm front discs to increase the effectiveness of the brakes on loose surfaces by up to 20 per cent.

In refinement the Touareg bears comparison with luxury saloons, thanks to careful attention to the reduction of cabin noise and vibration.  All models in the range are well appointed and equipped, and there is a comprehensive array of optional luxury equipment including the powerful new 620-watt Dynaudio entertainment system.

The most powerful model in the Touareg range has attracted considerable interest, not least because of its advanced and award-winning V10 TDI engine – one of the most powerful passenger car diesels – which produces an exceptional 553 lbs ft of torque at 2,000 rpm and 313 PS at 3,750 rpm.  This power was employed to demonstrate the towing capabilities of the Touareg by hauling a 155-tonne Boeing 747-200.  

In 2008, Volkswagen UK sold 2,578 Touaregs, and total sales of large 4x4 vehicles in the UK generated an overall segment share of 1.76 per cent.  Since its launch in 2003 over 18,400 Touaregs have been sold in the UK alone.

DESIGN

Exterior

The Touareg’s front design was adapted in January 2007, giving it greater presence thanks to a new chrome grille element and a set of reprofiled headlights and front wings.  More subtle are the reprofiled and more aerodynamic wing mirrors which incorporate high-level indicator lights.  

The Touareg has an imposing kerbside presence, yet is also one of the lowest vehicles in the class; this dimensional ratio gives it an especially dynamic appearance – with no loss in cabin headroom or ground clearance.

The aesthetic changes extend to the rear of the Touareg where a set of distinctive light units frame a new rear bumper and subtly restyled tail pipes.

Its generous ground clearance of 237 mm (300 mm with air suspension), large wheels (from 17 to 21 inches fitted as standard depending on model) and detailed design features reflect not only the Touareg’s power and ruggedness but also its luxurious nature. 

Front and rear overhangs are crucial to the abilities of an off-road vehicle.  Measured from the centre of the axle, the front overhang is 926 mm and the rear overhang

973 mm, providing an angle of approach and departure of 28 degrees for models with steel suspension and 33 degrees with air suspension.

Thanks to a complex three-part door sealing system, waterproof headlights and connectors, and a special air intake system, the Touareg is capable of fording depths of up to 500 mm, or 580 mm with air suspension.

Fully galvanised body construction

The fully galvanised construction of the Touareg’s body results in extremely high static and dynamic rigidity.  Torsional rigidity is to class-leading levels and loads are evenly distributed throughout the body, resulting in the solid functioning of doors, bonnet and boot lid, as well as allowing narrow panel gaps.

High-tech construction materials

The majority of the Touareg’s body parts are manufactured from high-grade fully galvanised steel.  Exceptions include the front wings, which are made from flexible plastics, the aluminium bonnet, and the bumpers which employ thermal-resistant plastics.  Two-shell construction ensures that the plastic front wings offer a very high degree of rigidity while at the same time ensuring maximum protection for pedestrians in the event of a collision.  Pedestrians also benefit from the use of aluminium for the bonnet, this metal providing the optimum deformation characteristics in an accident as well as saving weight. 

Acoustic characteristics

From the outset Volkswagen’s engineers intended the Touareg to attain luxury saloon levels of refinement and, to that end, have made the most of the latest technological developments to ensure impressive acoustic results.  Among the measures taken are:

  • the sealing of all body-frame openings to the interior
  • a three-part sealing system for doors, windows and luggage compartment
  • engine compartment encapsulation
  • maximum absorption in drive assembly, drive tunnel and damping systems
  • selective use of aluminium-sandwich sound deadening materials
  • optimised wheel-housing liners
  • specially absorbent materials in the roof lining, luggage compartment, pillar trim and dashboard

Two-piece tailgate with separately opening window

The large tailgate and its separately opening window offer optimum accessibility to the Touareg’s load area.  The two-piece tailgate is unlocked via an electro-mechanical system; a power-closing aid is an option on all models.  Aluminium roof mounted C-rails are standard equipment, to which a specially designed roof-carrier system can be attached.  So strong and rigid is the Touareg’s bodywork that it can carry a roof load of 100 kg – some 25 kg greater than most competitors.

The Touareg may tow a braked trailer of up to 3,500 kg; a factory-fit towbar with trailer stabilisation facility is available as an option.  The Touareg V10 TDI has proved its capability as a towcar, claiming The Caravan Club Towcar of the Year Awards for 2004 and 2005 in the full-size 4x4 category and setting what is thought to be a record for a production car in towing a 155-tonne Boeing 747.  

Interior

The interior combines functional aesthetics, comfort and impressive space efficiency to create an atmosphere which unites the ruggedness of a highly capable off-road vehicle with the elegance of a luxury saloon.  The Touareg’s dashboard combines the use of class-leading materials, ergonomics and appearance.  Clarity and ease of use are traditional Volkswagen design virtues that have been carefully encapsulated into the Touareg’s facia.

Careful consideration has been given to the materials used in the cabin.  There are wood inlays in the dash panel, centre console, door trim and gear knob, and even the plastics used are, with their refined high-tech surfaces, reminiscent of natural materials.  Leather seat upholstery is standard on all but the entry-level models.

Controls and displays

Most of the instruments feature round analogue displays with chrome surrounds, located behind anti-reflection mineral glass and illuminated by cathode lighting. 

The centre console has been designed with ease of use firmly in mind.  In the vertical area the centre air vents are located behind a lockable storage compartment and there are easily accessible audio system controls.  Below these are the 2Zone Climatronic controls.  The horizontal portion of the centre console contains the switch for deactivating the front-passenger airbag, the engine start button for models equipped with keyless access, and the controllers for the four-wheel drive and running gear.  All models feature a leather steering wheel equipped with controls for the multifunction computer, cruise control and sound system.  Tiptronic gearchange steering column controls are an option.

Stowage compartments

A large central armrest is located between the driver and front-seat passenger, just behind the two cup holders.  The armrest rises to expose a storage compartment for a one litre drinks bottle and a further, illuminated stowage compartment.  The glove compartment is generously proportioned as well as air conditioned, and there are further, stowage compartments in front of the gearshift (in lieu of the ashtray with the ‘non-smoker pack’) and in the upper area of the dashboard. 

Driver and front-passenger seating system

The ergonomic contours of the 2.5-litre TDI and V6 models’ front seats offer manual fore and aft adjustment, back-inclination adjustment and also manual height adjustment.  Twelve-point electrical adjustment of the seats and lumbar support is a standard feature of the V10 TDI model.  A memory pack, which recalls the settings for the steering column, both front seats, seat belt height and wing mirrors, is an option on the 2.5-litre TDI and V6 models, and standard on the V10 TDI.

Rear seating and load area

At the rear, the Touareg features individually contoured seats with three headrests, a trio of three-point seat belts and a centre armrest.  All models feature 60/40 split/folding rear seats.  The Touareg boasts one of the largest luggage compartments in its class; the 2.5-litre and V6 models offer between 555 and 1,570 litres of load space, and the V10 TDI between 500 and 1,525 litres depending on whether the seats are up or down.

ENGINES

The Touareg is available with a choice of four engines: a 2.5-litre five-cylinder TDI with 174 PS; a common rail 3.0-litre V6 TDI with 240 PS; a 3.6-litre V6 petrol with 280 PS; and a 5.0-litre V10 TDI with 313 PS.

Petrol engine

3.6-litre, 3600 cc, 24-valve 6-cyl V6, 280 PS

The only petrol engine in the Touareg line-up is a V6 unit producing 280 PS and 265 lbs ft of torque at 2,500 to 5,000 rpm.  Driving through a standard six-speed automatic tiptronic gearbox, it can go from 0 to 62 mph in 8.6 seconds and on to a top speed of 135 mph.  A combined fuel consumption figure of over 20 mpg is very respectable for this type of vehicle.

Diesel engines

2.5-litre TDI, 2461 cc, 10-valve 5-cyl, 174 PS

This in-line five cylinder unit uses ‘Pumpe Düse’ or unit injector technology and is effectively half of the 5.0-litre V10 TDI, featuring many of its sophisticated components.  In the Touareg, it is installed longitudinally.  The unit features aluminium cylinder block and crankcase; plasma coated cylinder lining surfaces; a balancer shaft to reduce vibration, and a variable geometry turbocharger.  For long life and reduced servicing costs, the camshafts and all ancillaries are gear-driven.

This engine also has an advanced diesel particulate filter (DPF) designed to trap diesel particulates before they can escape the exhaust system.  The DPF is maintenance free and entirely self-regenerating.  The 2.5-litre TDI produces 174 PS at 3,500 rpm and 295 lbs ft (400 Nm) of torque at 2,000 rpm.  Customers have the choice of a six speed manual or auto tiptronic gearbox.

3.0-litre TDI, 2967 cc, 24-valve V6, 240 PS

Launched in April 2008, this new 3.0-litre V6 TDI features common rail technology to deliver greater refinement and a useful boost in power while returning higher fuel economy and emitting less CO2 than the previous 3.0-litre V6 powerplant.

The 3.0-litre diesel engine fitted to the Touareg has enjoyed sustained popularity with UK buyers, accounting for 68 per cent of all sales of the vehicle.  The new common rail engine draws on the virtues of the outgoing unit yet raises the power output by 15 PS to a total of 240 PS and the available torque from 369 lbs ft to 406 lbs ft.  The result is a significant gain in performance, with the time taken to accelerate from 0 to 62 mph dropping from 9.2 to 8.3 seconds.  Despite these gains, CO2 output falls from 278 g/km to 262 g/km.  The 3.0-litre V6 engine is linked to a six speed tiptronic gearbox and four-wheel drive.  This new Euro 5 compliant engine also features a Diesel Particulate Filter (DPF) in the exhaust system

5.0-litre, 4921 cc, 20-valve V10 TDI, 313 PS

The advanced V10 TDI is one of the most powerful passenger car diesel engines, producing an exceptional 553 lbs ft (750 Nm) of torque at 2,000 rpm and 313 PS at 3,750 rpm.  It can accelerate from rest to 62 mph in 7.4 seconds and go on to a top speed of 140 mph.  Its combined fuel economy figure is nonetheless a very creditable 22.4 mpg.

The key factors in creating the V10 TDI’s extraordinary advancements in power and performance are, in addition to the large displacement, the advanced Pumpe Düse high pressure direct injection system and twin turbocharging system.  Exceptionally long gearing of just under 40 mph per 1,000 rpm in sixth gear assists in providing effortless progress.  For the first time, all engine ancillaries are mounted on one casing that is acoustically decoupled from the engine to aid refinement.

In addition to the extraordinarily high torque and performance characteristics, and the requirement for compact dimensions, one of the most important development goals was that the unit should be exceptionally quiet and offer very low vibration.  One of Volkswagen’s solutions for achieving this is to use a balancer shaft rotating counter to the crankshaft. 

The construction of the cylinder head is similar to that of other TDI PD engines pioneered by Volkswagen.  However, for use in the Touareg’s V10 TDI, the unit was redesigned, with a crossflow layout.  Direct injection itself takes on a key role: it optimises the mean pressures, the specific performance and the exhaust gas quality.  The new unit injectors used in the ten-cylinder engine have improved efficiency, a more compact solenoid valve and a significantly increased partial-load injection pressure.  A completely redeveloped engine electronic system, with two powerful control units, enables the precise regulation of the ten unit injection elements and adapts engine performance to the requirements of the gearbox and 4XMOTION.

The inlet and exhaust systems of the V10 TDI are particularly interesting.  All of the important components are arranged as two independent systems, one per cylinder bank.  These include the air filter, the hot film air flow meter, the turbocharger, the intercooler, the exhaust gas recirculation (line and valve) and the ‘throttle’ valves. 

As a result, the V10 consists of two five-cylinder engines where the air and exhaust are completely separated, but which are coupled through their control systems.

For the V10 TDI, Volkswagen also developed a new electronic control unit.  Designated EDC 16, it is a ‘double’ unit, with a 32-bit microprocessor and significantly improved computing performance.  One control unit regulates each five-cylinder bank.

The innovative design of the exhaust-gas system, with its two chrome-plated tailpipes, is an essential element of the exhaust-gas cleaning system.  The engine is also equipped with pneumatically controlled exhaust recirculation valves for reducing emissions.  Oxidation catalytic converters close to the engine help optimise the already low emissions.

Gearboxes

A six-speed manual gearbox is available on the 2.5-litre TDI, while a six-speed automatic tiptronic gearbox is standard on all models.

The gearboxes were specially designed for the Touareg with weight saving in mind; steel construction is used only for those components which are subjected to extreme performance demands.  All other components are made from aluminium.

Servicing

Volkswagen offers customers a choice of servicing regime for their Touareg.  They can choose Time and Distance or LongLife Servicing and the appropriate selection is entirely dependent on how the car is likely to be driven and its general use. 

Time and Distance Servicing is recommended for vehicles that will cover less than 10,000 miles in 12 months and if the vehicle is likely to be used in the following way:

  • Predominantly city centre driving, short journeys with frequent cold starts
  • Activities regularly producing high engine loading, for example frequent hill climbs, driving with vehicle fully loaded and towing
  • Driving with high rpm, hard acceleration and heavy braking

In this case, the vehicle will be serviced at regular intervals, at every 10,000 miles or every 12 months. 

LongLife Servicing is recommended for vehicles with a daily mileage of more than 25 miles, where the vehicle is driven regularly and on mainly longer distance journeys.  The vehicle should be mainly driven at a constant speed with minimum vehicle and engine loading, minimal towing and driven in an economical manner.  In this case, the on-board computer informs the driver via a dashboard display, when the vehicle needs a service.  A range of engine sensors electronically monitors the vehicle’s oil temperature, oil pressure, oil level and brake pad wear to establish when a service is needed. 

With the LongLife system, the vehicle can cover typically between 10,000 and 18,000 miles (approx) or 24 months (whichever is sooner) between oil changes.  An inspection service is typically due in the third year of ownership or at 40,000 miles and thereafter every second year for vehicles with an annual mileage of around 10,000 miles.

Customers can choose between Time and Distance or LongLife Servicing at PDI (pre-delivery inspection) and though it is possible to change from one to another during the vehicle’s life, it can only be done when a full inspection service is due. 

RUNNING GEAR

Front and rear axle

Two different suspension systems are available on the Touareg: a steel double-wishbone arrangement is standard, while on the V10 TDI model, the advanced Continuous Damping Control (CDC) self-levelling air suspension system is employed (optional on SE and Altitude models).     

The independent steel suspension features, at the front, double wishbones with aluminium upper suspension and steel lower links.  At the rear, double wishbones with forged aluminium upper links and steel lower wishbones are used.  With this suspension, the Touareg possesses a maximum ground clearance of 237 mm.

Continuous Damping Control (CDC) air suspension system

CDC, standard equipment on the V10 TDI, is an option on other SE and Altitude models.  Like the system found in the Phaeton, the Touareg’s CDC guarantees extremely high comfort levels and, thanks to automatic speed-sensitive ride height adjustment, provides sporty dynamic characteristics for on-road driving.

CDC maintains the Touareg at a constant ride height.  Four sensors continuously monitor the distance between axle and body; when a deviation from the required position is sensed it is corrected by means of solenoid valves, a compressor and two accumulators.  The Touareg’s four air-spring dampers consist essentially of air-spring bellows, a roller piston and the regulated hydraulic damper unit.

The damping system sensors assess the vehicle’s speed and the driving conditions and compensates for them with automatic adjustment of the dampers.  The system reacts to the slightest unevenness in the road and can minimise roll and pitch in the event of sudden extreme acceleration or braking.

Console-mounted rotary switches give the driver control of the Touareg’s air suspension settings and the degree of damping.  There are three driver-selectable suspension settings: Comfort, Sport and Auto.

Variable ground clearance

The Touareg’s air suspension system raises and lowers the vehicle automatically depending on the speed at which the car is being driven.  At 78 mph, for example, the ride height drops from 215 mm to 190 mm, and at 112 mph it is further reduced to 180 mm.  The driver can override the system and set other levels if desired.

  • Loading level: 160 mm ground clearance (up to 5 km/h)
  • Street level: 215 mm (0-125km/h)
  • High speed I: 190 mm (125-180 km/h)
  • High speed II: 180 mm (from 180 km/h)
  • Off-road level: 240 mm (up to 70 km/h)
  • X’tra level: 300 mm (up to 20 km/h)

 4XMOTION four-wheel drive system

All Touaregs are equipped with a continuous 4XMOTION four-wheel drive system which guarantees exceptional off-road ability combined with a high degree of safety and excellent on-road dynamics.

The 4XMOTION system delivers its power to the front and rear axles via a transfer box and a central differential, featuring a continuously adjustable and automatically operated multi-disc clutch, which performs the differential lock function.  How much of the engine’s power is delivered to the front and rear axles is dependent on conditions – up to 100 per cent of the drive force can be transmitted to either of the two axles if required.  The differential lock is automatically regulated by engine torque and wheel slippage, with the driver having manual override via a console mounted switch.  Manually lockable front and rear axle differentials are optional.

On-road benefits of 4XMOTION

4XMOTION offers a high degree of safety.  Under normal driving conditions – a dry road with even grip and constant engine power – the four-wheel drive system provides a 50:50 distribution of power to the front and rear axles.  In conditions where a wheel begins to lose traction, for example, as a result of aquaplaning, the centre differential’s multi-disc lock increases the flow of power – up to 100 per cent – to whichever axle has more grip.

Off-road benefits of 4XMOTION

4XMOTION allows optimum levels of off-road grip and traction, such as the ability to tackle a lateral inclination of up to 35 degrees, and a climbing angle of 45 degrees.  When faced with demanding terrain, the driver activates ‘low range’ transmission via an electrical switch on the centre console.  Moving the ‘Auto Diff’ switch from the fast ‘High’ mode towards ‘Low’ results in activation of the automatic central differential lock, which continuously checks for loss of traction and adjusts front/rear power distribution accordingly.

If desired the differential lock can be activated manually by the driver, up to 100 per cent, via a dashboard rotary switch.  The same principle applies to the (optional) lockable axle differentials.

A hill-starting assistant aids drivers of models with manual transmission; it activates automatically when the Touareg, with engine running, is stopped on an incline with the normal or parking brake engaged and when in first or reverse gear with the clutch pedal depressed.  When the driver releases the brakes the car is actively braked and automatically held on the incline; as the clutch is engaged so the brakes are released step by step. 

Touaregs with automatic gearboxes also have a hill-starting assistant which, via an electronic function in the gearbox, prevents downhill movement before moving off.  On very steep (more than 20 per cent) downward slopes, an automatic downhill assistant cuts in when speeds are below 20 km/h (with ESP switched on) to maintain steady and safe downhill progress.

Braking system

The Touareg’s 4XMOTION permanent four-wheel-drive system provides sure-footed off-road characteristics and a high degree of safety on normal roads by transmitting power to the front or rear in amounts appropriate to the levels of grip available at each axle.

The Touareg features internally ventilated fixed calliper disc brakes (330 mm diameter) on all four wheels, while its stopping systems are technologically advanced, featuring ABS, EBD (Electronic Brake-force Distribution) and ESP (Electronic Stabilisation Programme) with Hydraulic Braking Assistant (HBA). ABSplus is available as an option.

ABSplus

The new ABSplus generation has been developed specifically for off-road vehicles and arrives with the new Touareg.  The new anti-lock braking system, for which Volkswagen has applied for a patent, reduces braking distance on loose surfaces such as sand or gravel by up to 20 per cent.

The new system automatically switches on an Off-road ABS function when both Low Gear Mode (off-road driving with off-road gear ratio reduction) and High Gear Mode (faster on-road driving).  Until now Off-road ABS was only available in the Low Gear range with substantially lower performance.  To reduce braking distance on loose driving surfaces the ABS must recognise the composition of the substrate and select the optimal control strategy via ESP (Electronic Stabilisation Programme) sensors – and this is a complex task.  Loose driving surfaces exhibit friction values ranging from µ = 0.4 to µ = 0.65.

On these loose substrates maximum deceleration is achieved at 100 per cent brake slip (locked wheels).  In this condition the vehicle is unstable and cannot be steered.  This is where ABSplus intervenes. Taking into account various parameters including pedal effort, wheel speeds and vehicle deceleration it induces alternate phases of high levels of slip and lesser slip, and this makes it possible to achieve reduced braking distance, braking stability and steering control.

Hydraulic Brake Assist – HBA

Working in conjunction with the other elements of the braking system, HBA recognises from the speed at which the brake pedal is depressed whether it is a ‘normal’ braking situation or an emergency stop.  In the event of an emergency stop, HBA automatically increases braking pressure, activating ABS and ensuring the level of braking meets the needs of the conditions.  The application of brake assist makes it possible even for unskilled drivers to reduce braking distances by 25 per cent.

Electronic Stabilisation Programme – ESP

This is a sophisticated system that automatically senses any tendency for the car to slide.  Should this situation occur, ESP reacts by applying the brakes to one, two, three or all four wheels and adjusts the engine’s power.  In this way, it is possible that a skid is corrected even before the driver is aware that one has started.  This can be useful if a tendency to understeer or oversteer develops in a bend.  In such circumstances ESP can help prevent the car skidding or spinning off the road and is particularly helpful in wet or icy conditions.    

Trailer stabilisation

This function greatly improves stability when towing by sensing the onset of a snaking motion and then neutralising it.  It is standard on all Touareg models fitted with a factory-fit towbar. 

This system extends the capability of the normal Electronic Stabilisation Programme purely through a software extension.  It does not require additional sensors.

When the onset of yawing of a trailer is detected by the ESP control module the system automatically reduces or cuts engine power and applies the brakes to appropriate wheels dynamically in phase with the yawing to oppose the snaking motion and stabilise the vehicle / trailer combination.  When stability is achieved the brakes and engine power return to normal control.  During the automatic braking process the brake lights are turned on even though the driver may not be touching the brake pedal. 

Rollover sensors

The Touareg’s ability off-road is boosted by the addition of new rollover sensors.  The system scrutinises vehicle acceleration, yaw angle and yaw speeds.  Should the system detect that a rollover is imminent the head / thorax airbags are automatically deployed to reduce the risk of injury.

Automatic Distance Control - ADC

Available as an option on Touareg, Automatic Distance Control (ADC) works in conjuction with the cruise control and the radar-based Front Assist distance monitoring systems.  Operated via buttons on the multifunction steering wheel, the system uses sensors to scan the road ahead for any dangers and can, if necessary, slow the vehicle to a complete halt.

The Front Assist system monitors the distance between other vehicles ahead and alerts the driver if a vehicle is too close, through a two stage warning.  An initial visual and audible alert is followed by a brief application of the brakes if no action is taken.  At the same time, the vehicle’s braking system is prepared for an emergency braking manoeuvre.

Side scan lane change assist

Side scan lane change assist monitors the ‘blind spot’ next to the vehicle and acts as a lane changing aid with an audible alert and a small warning lamp in the wing mirrors to warn of the danger of collision.

As befits a car of this class, there is an extensive range of optional equipment available for the Touareg.  This includes items such as Tiptronic gearchange controls mounted on the steering column; a boot-mounted six-disc CD autochanger; electric sunroof; powered tailgate closing; roof bars; a ski sack with load-through provision; side steps; and sunblinds for the rear screen and rear side windows.

Continuous Damping Control (CDC) air suspension

This feature is standard equipment on the V10 TDI and can be specified as an option on SE and Altitude models.  It ensures further comfort and, thanks to automatic speed-sensitive ride height adjustment, provides sporty dynamic characteristics while on the road as well as improved off-road handling.

Front and rear differential locks

As a further aid to off-road traction in extreme conditions, manually operated differential locks can be specified for the rear axle or for both front and rear axles. 

Navigation/radio/TV system

The satellite navigation system, standard on SE and Altitude models and an option on the entry-level Touareg, consists of a screen display housed in the dashboard which shows the required direction of travel, combined with verbal instructions.

Wheel sensors are used to determine the distance the car has covered and to provide information when the car is turning.  Further system components include a solid state magnetic compass and a GPS (Global Positioning System) aerial in the front left wing.  The aerial receives signals from orbiting satellites from which it is able to calculate the position of the car to within 100 metres.  A road map, effectively a digitised street plan of Great Britain or other country, is stored on DVD and is accessed by the on-board computer as it calculates the route required to reach the desired destination.

The range-topping navigation system also incorporates a television which, for safety reasons, operates when the vehicle is stationary and the handbrake is applied.  An entertainment pack with a DVD screen in the roof liner is also available.  

Keyless entry and start function

The keyless system is available as an option on SE and Altitude models with the auto Tiptronic gearbox.  With it, the driver need never remove the Touareg’s key from his or her pocket.  The car ‘recognises’ its driver via a transponder in the key, releases the lock when the driver touches the door handle and allows the engine to be started with the push of a button.

The system features several safety mechanisms.  For example, the Touareg will start only when the key is actually within the vehicle’s interior, and the driver must press the clutch or, on automatic models, the brake pedal.  On exit, the driver has only to touch the door handle once more to activate the automatic closing and locking procedure.  For security, the system only operates when the key is in close proximity to the vehicle.   

SAFETY

Volkswagen’s intention with the Touareg was to set the highest possible standards for active and passive safety, and to prove that the safety levels of a luxury saloon can be replicated in a luxury off-road vehicle.

The strength of the Touareg’s construction, its incorporation of the very latest in electronic safety features and the inherent stability of its four-wheel-drive and traction control systems raise standards to a significant new level.

Frontal collision

The Touareg was designed with very high frontal energy absorption characteristics and with an extremely rigid passenger cell, in line with both Euro NCAP and US crash legislation requirements.

Among the special protective measures adopted are additional strengthening bars in the sills, extremely rigid A-, B-, C- and D-pillars and the use of high quality steels in the construction, along with laser welding.

Side collision

The Touareg’s doors are integrated with the car’s crash protection structure, and are designed to afford passengers the maximum protection in the event of a side impact.

Passive safety

Touareg passengers benefit from a state-of-the-art electronic safety system featuring crash sensors which can judge the severity of an impact and react accordingly, triggering either a low-level response from the driver and front passenger airbags or a full-intensity response.

All models in the range feature driver and front passenger airbags, front side airbags and curtain airbags which cover the entire window surface between the A- and C- pillars to protect the heads and upper torsos of the window-seat passengers.

The Touareg also features electrically activated seat belt pre-tensioners to restrict passenger movement in an impact.  All models feature five three-point harnesses as standard.

The electronic safety system continues to work even after it has activated the airbags, automatically unlocking all the doors, isolating the battery, shutting down the fuel supply and all high-power electrical units, as well as switching on the hazard warning lights.

Child passenger protection

All Touareg models are equipped as standard with rear Isofix seat mounting brackets.  These are attached to the body of the car and allow a compatible Isofix standard child safety seat to be correctly installed with ease.  If small children are to be carried in a safety seat mounted in the front passenger seat, the front-seat passenger airbag system can be switched off. 

Pedestrian safety

The Touareg’s design team also gave careful consideration to minimising injury to pedestrians in the event of a collision.  Volkswagen does not offer a ‘bull bar’ for the Touareg and the car’s body design possesses a number of features which optimise protection for pedestrians and cyclists.  Among these is the construction of the bonnet in aluminium to provide optimum deformation characteristics, and the use of plastic materials for the wings.

Parking distance control is a standard feature of the SE V10 TDI and an option on other models.  This system features ultrasonic transmitters and receivers in the front and rear bumpers to warn the driver of obstacles; the front sensor can ‘see’ up to 1,200 mm and the rear sensor up to 1,500 mm.  If the Touareg approaches an obstacle it gives both an audible warning and a visual one, by means of a dashboard display and a roof-mounted display visible in the rear-view mirror.

Euro NCAP test results

In recognition of the Touareg’s safety features, the previous model was awarded a full five stars in the Euro NCAP (European New Car Assessment Programme) safety tests for adult occupant protection.  It scored four stars for child occupant protection and gained a one star pedestrian rating.  

SECURITY

All models in the Touareg range are fitted as standard with an electronic engine immobiliser and an alarm system with interior protection and remote central locking.  For added convenience and security, a keyless entry and start system is an option on automatic SE and Altitude models.  All Touaregs also feature an integrated factory-fitted CD/radio system which is Volkswagen branded and security coded.

Line-up with insurance groups

Thanks to its safety and security systems, the Touareg has the following insurance group ratings from the ABI (Association of British Insurers):

Touareg Altitude

WARRANTIES

The Touareg has a three year or 60,000 mile mechanical warranty, the first two years of which are covered by the manufacturer.  The final year’s cover is a retailer warranty.  In addition, it comes with a class-leading 12 year body protection warranty, three year paintwork warranty and three years membership of Volkswagen Assistance which includes pan-European breakdown cover.

The second generation Touareg made its debut at the Paris Motor Show in September 2006 and launched in the UK in January 2007.  Building on the success of the first generation model, the new Touareg exhibits some significant technical updates including ABSplus, rollover protection, and an optional trailer stabilisation system.  External design updates accompany the changes below the skin. 

Volkswagen’s first venture into the luxury 4x4 market was led by the Touareg (launched in Spring 2003), a model that remains one of the most sophisticated vehicles in its segment.  It combines true off-road ability with the comfort and refinement of a luxury saloon.

Starting with a clean sheet, the Touareg is designed to deliver class-leading performance both on and off the road.  Features such as permanent four-wheel drive, low and high gear ratios, electronic traction control linked to an auto-locking centre differential, hill start and descent assist, a rollover sensor and short front and rear overhangs all contribute to class-leading capability when venturing off the beaten track.  Versions with air suspension with the benefit of automatic and manual height adjustment have enhanced off-road ability and can ford depths of up to 580 mm.  On the road, the Touareg benefits from a host of electronic driver aids, such as enhanced ABS, brake assist and ESP (Electronic Stabilisation Programme).  The revised system incorporates Active Rollover Protection (ARP), rain brake support, fading brake support and understeer control logic which sharpens the Touareg’s turning behaviour through a corner.

The latest model also debuts Volkswagen’s pioneering braking system – ABSplus.  This works in conjunction with the Touareg’s ABS linked to 330 mm front discs to increase the effectiveness of the brakes on loose surfaces by up to 20 per cent.

In refinement the Touareg bears comparison with luxury saloons, thanks to careful attention to the reduction of cabin noise and vibration.  All models in the range are well appointed and equipped, and there is a comprehensive array of optional luxury equipment including the powerful new 620-watt Dynaudio entertainment system.

The most powerful model in the Touareg range has attracted considerable interest, not least because of its advanced and award-winning V10 TDI engine – one of the most powerful passenger car diesels – which produces an exceptional 553 lbs ft of torque at 2,000 rpm and 313 PS at 3,750 rpm.  This power was employed to demonstrate the towing capabilities of the Touareg by hauling a 155-tonne Boeing 747-200.  

In 2008, Volkswagen UK sold 2,578 Touaregs, and total sales of large 4x4 vehicles in the UK generated an overall segment share of 1.76 per cent.  Since its launch in 2003 over 18,400 Touaregs have been sold in the UK alone.

DESIGN

Exterior

The Touareg’s front design was adapted in January 2007, giving it greater presence thanks to a new chrome grille element and a set of reprofiled headlights and front wings.  More subtle are the reprofiled and more aerodynamic wing mirrors which incorporate high-level indicator lights.  

The Touareg has an imposing kerbside presence, yet is also one of the lowest vehicles in the class; this dimensional ratio gives it an especially dynamic appearance – with no loss in cabin headroom or ground clearance.

The aesthetic changes extend to the rear of the Touareg where a set of distinctive light units frame a new rear bumper and subtly restyled tail pipes.

Its generous ground clearance of 237 mm (300 mm with air suspension), large wheels (from 17 to 21 inches fitted as standard depending on model) and detailed design features reflect not only the Touareg’s power and ruggedness but also its luxurious nature. 

Front and rear overhangs are crucial to the abilities of an off-road vehicle.  Measured from the centre of the axle, the front overhang is 926 mm and the rear overhang

973 mm, providing an angle of approach and departure of 28 degrees for models with steel suspension and 33 degrees with air suspension.

Thanks to a complex three-part door sealing system, waterproof headlights and connectors, and a special air intake system, the Touareg is capable of fording depths of up to 500 mm, or 580 mm with air suspension.

Fully galvanised body construction

The fully galvanised construction of the Touareg’s body results in extremely high static and dynamic rigidity.  Torsional rigidity is to class-leading levels and loads are evenly distributed throughout the body, resulting in the solid functioning of doors, bonnet and boot lid, as well as allowing narrow panel gaps.

High-tech construction materials

The majority of the Touareg’s body parts are manufactured from high-grade fully galvanised steel.  Exceptions include the front wings, which are made from flexible plastics, the aluminium bonnet, and the bumpers which employ thermal-resistant plastics.  Two-shell construction ensures that the plastic front wings offer a very high degree of rigidity while at the same time ensuring maximum protection for pedestrians in the event of a collision.  Pedestrians also benefit from the use of aluminium for the bonnet, this metal providing the optimum deformation characteristics in an accident as well as saving weight. 

Acoustic characteristics

From the outset Volkswagen’s engineers intended the Touareg to attain luxury saloon levels of refinement and, to that end, have made the most of the latest technological developments to ensure impressive acoustic results.  Among the measures taken are:

  • the sealing of all body-frame openings to the interior
  • a three-part sealing system for doors, windows and luggage compartment
  • engine compartment encapsulation
  • maximum absorption in drive assembly, drive tunnel and damping systems
  • selective use of aluminium-sandwich sound deadening materials
  • optimised wheel-housing liners
  • specially absorbent materials in the roof lining, luggage compartment, pillar trim and dashboard

Two-piece tailgate with separately opening window

The large tailgate and its separately opening window offer optimum accessibility to the Touareg’s load area.  The two-piece tailgate is unlocked via an electro-mechanical system; a power-closing aid is an option on all models.  Aluminium roof mounted C-rails are standard equipment, to which a specially designed roof-carrier system can be attached.  So strong and rigid is the Touareg’s bodywork that it can carry a roof load of 100 kg – some 25 kg greater than most competitors.

The Touareg may tow a braked trailer of up to 3,500 kg; a factory-fit towbar with trailer stabilisation facility is available as an option.  The Touareg V10 TDI has proved its capability as a towcar, claiming The Caravan Club Towcar of the Year Awards for 2004 and 2005 in the full-size 4x4 category and setting what is thought to be a record for a production car in towing a 155-tonne Boeing 747.  

Interior

The interior combines functional aesthetics, comfort and impressive space efficiency to create an atmosphere which unites the ruggedness of a highly capable off-road vehicle with the elegance of a luxury saloon.  The Touareg’s dashboard combines the use of class-leading materials, ergonomics and appearance.  Clarity and ease of use are traditional Volkswagen design virtues that have been carefully encapsulated into the Touareg’s facia.

Careful consideration has been given to the materials used in the cabin.  There are wood inlays in the dash panel, centre console, door trim and gear knob, and even the plastics used are, with their refined high-tech surfaces, reminiscent of natural materials.  Leather seat upholstery is standard on all but the entry-level models.

Controls and displays

Most of the instruments feature round analogue displays with chrome surrounds, located behind anti-reflection mineral glass and illuminated by cathode lighting. 

The centre console has been designed with ease of use firmly in mind.  In the vertical area the centre air vents are located behind a lockable storage compartment and there are easily accessible audio system controls.  Below these are the 2Zone Climatronic controls.  The horizontal portion of the centre console contains the switch for deactivating the front-passenger airbag, the engine start button for models equipped with keyless access, and the controllers for the four-wheel drive and running gear.  All models feature a leather steering wheel equipped with controls for the multifunction computer, cruise control and sound system.  Tiptronic gearchange steering column controls are an option.

Stowage compartments

A large central armrest is located between the driver and front-seat passenger, just behind the two cup holders.  The armrest rises to expose a storage compartment for a one litre drinks bottle and a further, illuminated stowage compartment.  The glove compartment is generously proportioned as well as air conditioned, and there are further, stowage compartments in front of the gearshift (in lieu of the ashtray with the ‘non-smoker pack’) and in the upper area of the dashboard. 

Driver and front-passenger seating system

The ergonomic contours of the 2.5-litre TDI and V6 models’ front seats offer manual fore and aft adjustment, back-inclination adjustment and also manual height adjustment.  Twelve-point electrical adjustment of the seats and lumbar support is a standard feature of the V10 TDI model.  A memory pack, which recalls the settings for the steering column, both front seats, seat belt height and wing mirrors, is an option on the 2.5-litre TDI and V6 models, and standard on the V10 TDI.

Rear seating and load area

At the rear, the Touareg features individually contoured seats with three headrests, a trio of three-point seat belts and a centre armrest.  All models feature 60/40 split/folding rear seats.  The Touareg boasts one of the largest luggage compartments in its class; the 2.5-litre and V6 models offer between 555 and 1,570 litres of load space, and the V10 TDI between 500 and 1,525 litres depending on whether the seats are up or down.

ENGINES

The Touareg is available with a choice of four engines: a 2.5-litre five-cylinder TDI with 174 PS; a common rail 3.0-litre V6 TDI with 240 PS; a 3.6-litre V6 petrol with 280 PS; and a 5.0-litre V10 TDI with 313 PS.

http://www.volkswagenpressoffice.co.uk/Technical_Specifications/touareg_spec.pdf

Petrol engine

3.6-litre, 3600 cc, 24-valve 6-cyl V6, 280 PS

The only petrol engine in the Touareg line-up is a V6 unit producing 280 PS and 265 lbs ft of torque at 2,500 to 5,000 rpm.  Driving through a standard six-speed automatic tiptronic gearbox, it can go from 0 to 62 mph in 8.6 seconds and on to a top speed of 135 mph.  A combined fuel consumption figure of over 20 mpg is very respectable for this type of vehicle.

Diesel engines

2.5-litre TDI, 2461 cc, 10-valve 5-cyl, 174 PS

This in-line five cylinder unit uses ‘Pumpe Düse’ or unit injector technology and is effectively half of the 5.0-litre V10 TDI, featuring many of its sophisticated components.  In the Touareg, it is installed longitudinally.  The unit features aluminium cylinder block and crankcase; plasma coated cylinder lining surfaces; a balancer shaft to reduce vibration, and a variable geometry turbocharger.  For long life and reduced servicing costs, the camshafts and all ancillaries are gear-driven.

This engine also has an advanced diesel particulate filter (DPF) designed to trap diesel particulates before they can escape the exhaust system.  The DPF is maintenance free and entirely self-regenerating.  The 2.5-litre TDI produces 174 PS at 3,500 rpm and 295 lbs ft (400 Nm) of torque at 2,000 rpm.  Customers have the choice of a six speed manual or auto tiptronic gearbox.

3.0-litre TDI, 2967 cc, 24-valve V6, 240 PS

Launched in April 2008, this new 3.0-litre V6 TDI features common rail technology to deliver greater refinement and a useful boost in power while returning higher fuel economy and emitting less CO2 than the previous 3.0-litre V6 powerplant.

The 3.0-litre diesel engine fitted to the Touareg has enjoyed sustained popularity with UK buyers, accounting for 68 per cent of all sales of the vehicle.  The new common rail engine draws on the virtues of the outgoing unit yet raises the power output by 15 PS to a total of 240 PS and the available torque from 369 lbs ft to 406 lbs ft.  The result is a significant gain in performance, with the time taken to accelerate from 0 to 62 mph dropping from 9.2 to 8.3 seconds.  Despite these gains, CO2 output falls from 278 g/km to 262 g/km.  The 3.0-litre V6 engine is linked to a six speed tiptronic gearbox and four-wheel drive.  This new Euro 5 compliant engine also features a Diesel Particulate Filter (DPF) in the exhaust system

5.0-litre, 4921 cc, 20-valve V10 TDI, 313 PS

The advanced V10 TDI is one of the most powerful passenger car diesel engines, producing an exceptional 553 lbs ft (750 Nm) of torque at 2,000 rpm and 313 PS at 3,750 rpm.  It can accelerate from rest to 62 mph in 7.4 seconds and go on to a top speed of 140 mph.  Its combined fuel economy figure is nonetheless a very creditable 22.4 mpg.

The key factors in creating the V10 TDI’s extraordinary advancements in power and performance are, in addition to the large displacement, the advanced Pumpe Düse high pressure direct injection system and twin turbocharging system.  Exceptionally long gearing of just under 40 mph per 1,000 rpm in sixth gear assists in providing effortless progress.  For the first time, all engine ancillaries are mounted on one casing that is acoustically decoupled from the engine to aid refinement.

In addition to the extraordinarily high torque and performance characteristics, and the requirement for compact dimensions, one of the most important development goals was that the unit should be exceptionally quiet and offer very low vibration.  One of Volkswagen’s solutions for achieving this is to use a balancer shaft rotating counter to the crankshaft. 

The construction of the cylinder head is similar to that of other TDI PD engines pioneered by Volkswagen.  However, for use in the Touareg’s V10 TDI, the unit was redesigned, with a crossflow layout.  Direct injection itself takes on a key role: it optimises the mean pressures, the specific performance and the exhaust gas quality.  The new unit injectors used in the ten-cylinder engine have improved efficiency, a more compact solenoid valve and a significantly increased partial-load injection pressure.  A completely redeveloped engine electronic system, with two powerful control units, enables the precise regulation of the ten unit injection elements and adapts engine performance to the requirements of the gearbox and 4XMOTION.

The inlet and exhaust systems of the V10 TDI are particularly interesting.  All of the important components are arranged as two independent systems, one per cylinder bank.  These include the air filter, the hot film air flow meter, the turbocharger, the intercooler, the exhaust gas recirculation (line and valve) and the ‘throttle’ valves. 

As a result, the V10 consists of two five-cylinder engines where the air and exhaust are completely separated, but which are coupled through their control systems.

For the V10 TDI, Volkswagen also developed a new electronic control unit.  Designated EDC 16, it is a ‘double’ unit, with a 32-bit microprocessor and significantly improved computing performance.  One control unit regulates each five-cylinder bank.

The innovative design of the exhaust-gas system, with its two chrome-plated tailpipes, is an essential element of the exhaust-gas cleaning system.  The engine is also equipped with pneumatically controlled exhaust recirculation valves for reducing emissions.  Oxidation catalytic converters close to the engine help optimise the already low emissions.

Gearboxes

A six-speed manual gearbox is available on the 2.5-litre TDI, while a six-speed automatic tiptronic gearbox is standard on all models.

The gearboxes were specially designed for the Touareg with weight saving in mind; steel construction is used only for those components which are subjected to extreme performance demands.  All other components are made from aluminium.

Servicing

Volkswagen offers customers a choice of servicing regime for their Touareg.  They can choose Time and Distance or LongLife Servicing and the appropriate selection is entirely dependent on how the car is likely to be driven and its general use. 

Time and Distance Servicing is recommended for vehicles that will cover less than 10,000 miles in 12 months and if the vehicle is likely to be used in the following way:

  • Predominantly city centre driving, short journeys with frequent cold starts
  • Activities regularly producing high engine loading, for example frequent hill climbs, driving with vehicle fully loaded and towing
  • Driving with high rpm, hard acceleration and heavy braking

In this case, the vehicle will be serviced at regular intervals, at every 10,000 miles or every 12 months. 

LongLife Servicing is recommended for vehicles with a daily mileage of more than 25 miles, where the vehicle is driven regularly and on mainly longer distance journeys.  The vehicle should be mainly driven at a constant speed with minimum vehicle and engine loading, minimal towing and driven in an economical manner.  In this case, the on-board computer informs the driver via a dashboard display, when the vehicle needs a service.  A range of engine sensors electronically monitors the vehicle’s oil temperature, oil pressure, oil level and brake pad wear to establish when a service is needed. 

With the LongLife system, the vehicle can cover typically between 10,000 and 18,000 miles (approx) or 24 months (whichever is sooner) between oil changes.  An inspection service is typically due in the third year of ownership or at 40,000 miles and thereafter every second year for vehicles with an annual mileage of around 10,000 miles.

Customers can choose between Time and Distance or LongLife Servicing at PDI (pre-delivery inspection) and though it is possible to change from one to another during the vehicle’s life, it can only be done when a full inspection service is due. 

RUNNING GEAR

Front and rear axle

Two different suspension systems are available on the Touareg: a steel double-wishbone arrangement is standard, while on the V10 TDI model, the advanced Continuous Damping Control (CDC) self-levelling air suspension system is employed (optional on SE and Altitude models).     

The independent steel suspension features, at the front, double wishbones with aluminium upper suspension and steel lower links.  At the rear, double wishbones with forged aluminium upper links and steel lower wishbones are used.  With this suspension, the Touareg possesses a maximum ground clearance of 237 mm.

Continuous Damping Control (CDC) air suspension system

CDC, standard equipment on the V10 TDI, is an option on other SE and Altitude models.  Like the system found in the Phaeton, the Touareg’s CDC guarantees extremely high comfort levels and, thanks to automatic speed-sensitive ride height adjustment, provides sporty dynamic characteristics for on-road driving.

CDC maintains the Touareg at a constant ride height.  Four sensors continuously monitor the distance between axle and body; when a deviation from the required position is sensed it is corrected by means of solenoid valves, a compressor and two accumulators.  The Touareg’s four air-spring dampers consist essentially of air-spring bellows, a roller piston and the regulated hydraulic damper unit.

The damping system sensors assess the vehicle’s speed and the driving conditions and compensates for them with automatic adjustment of the dampers.  The system reacts to the slightest unevenness in the road and can minimise roll and pitch in the event of sudden extreme acceleration or braking.

Console-mounted rotary switches give the driver control of the Touareg’s air suspension settings and the degree of damping.  There are three driver-selectable suspension settings: Comfort, Sport and Auto.

Variable ground clearance

The Touareg’s air suspension system raises and lowers the vehicle automatically depending on the speed at which the car is being driven.  At 78 mph, for example, the ride height drops from 215 mm to 190 mm, and at 112 mph it is further reduced to 180 mm.  The driver can override the system and set other levels if desired.

  • Loading level: 160 mm ground clearance (up to 5 km/h)
  • Street level: 215 mm (0-125km/h)
  • High speed I: 190 mm (125-180 km/h)
  • High speed II: 180 mm (from 180 km/h)
  • Off-road level: 240 mm (up to 70 km/h)
  • X’tra level: 300 mm (up to 20 km/h)

 4XMOTION four-wheel drive system

All Touaregs are equipped with a continuous 4XMOTION four-wheel drive system which guarantees exceptional off-road ability combined with a high degree of safety and excellent on-road dynamics.

The 4XMOTION system delivers its power to the front and rear axles via a transfer box and a central differential, featuring a continuously adjustable and automatically operated multi-disc clutch, which performs the differential lock function.  How much of the engine’s power is delivered to the front and rear axles is dependent on conditions – up to 100 per cent of the drive force can be transmitted to either of the two axles if required.  The differential lock is automatically regulated by engine torque and wheel slippage, with the driver having manual override via a console mounted switch.  Manually lockable front and rear axle differentials are optional.

On-road benefits of 4XMOTION

4XMOTION offers a high degree of safety.  Under normal driving conditions – a dry road with even grip and constant engine power – the four-wheel drive system provides a 50:50 distribution of power to the front and rear axles.  In conditions where a wheel begins to lose traction, for example, as a result of aquaplaning, the centre differential’s multi-disc lock increases the flow of power – up to 100 per cent – to whichever axle has more grip.

Off-road benefits of 4XMOTION

4XMOTION allows optimum levels of off-road grip and traction, such as the ability to tackle a lateral inclination of up to 35 degrees, and a climbing angle of 45 degrees.  When faced with demanding terrain, the driver activates ‘low range’ transmission via an electrical switch on the centre console.  Moving the ‘Auto Diff’ switch from the fast ‘High’ mode towards ‘Low’ results in activation of the automatic central differential lock, which continuously checks for loss of traction and adjusts front/rear power distribution accordingly.

If desired the differential lock can be activated manually by the driver, up to 100 per cent, via a dashboard rotary switch.  The same principle applies to the (optional) lockable axle differentials.

A hill-starting assistant aids drivers of models with manual transmission; it activates automatically when the Touareg, with engine running, is stopped on an incline with the normal or parking brake engaged and when in first or reverse gear with the clutch pedal depressed.  When the driver releases the brakes the car is actively braked and automatically held on the incline; as the clutch is engaged so the brakes are released step by step. 

Touaregs with automatic gearboxes also have a hill-starting assistant which, via an electronic function in the gearbox, prevents downhill movement before moving off.  On very steep (more than 20 per cent) downward slopes, an automatic downhill assistant cuts in when speeds are below 20 km/h (with ESP switched on) to maintain steady and safe downhill progress.

Braking system

The Touareg’s 4XMOTION permanent four-wheel-drive system provides sure-footed off-road characteristics and a high degree of safety on normal roads by transmitting power to the front or rear in amounts appropriate to the levels of grip available at each axle.

The Touareg features internally ventilated fixed calliper disc brakes (330 mm diameter) on all four wheels, while its stopping systems are technologically advanced, featuring ABS, EBD (Electronic Brake-force Distribution) and ESP (Electronic Stabilisation Programme) with Hydraulic Braking Assistant (HBA). ABSplus is available as an option.

ABSplus

The new ABSplus generation has been developed specifically for off-road vehicles and arrives with the new Touareg.  The new anti-lock braking system, for which Volkswagen has applied for a patent, reduces braking distance on loose surfaces such as sand or gravel by up to 20 per cent.

The new system automatically switches on an Off-road ABS function when both Low Gear Mode (off-road driving with off-road gear ratio reduction) and High Gear Mode (faster on-road driving).  Until now Off-road ABS was only available in the Low Gear range with substantially lower performance.  To reduce braking distance on loose driving surfaces the ABS must recognise the composition of the substrate and select the optimal control strategy via ESP (Electronic Stabilisation Programme) sensors – and this is a complex task.  Loose driving surfaces exhibit friction values ranging from µ = 0.4 to µ = 0.65.

On these loose substrates maximum deceleration is achieved at 100 per cent brake slip (locked wheels).  In this condition the vehicle is unstable and cannot be steered.  This is where ABSplus intervenes. Taking into account various parameters including pedal effort, wheel speeds and vehicle deceleration it induces alternate phases of high levels of slip and lesser slip, and this makes it possible to achieve reduced braking distance, braking stability and steering control.

Hydraulic Brake Assist – HBA

Working in conjunction with the other elements of the braking system, HBA recognises from the speed at which the brake pedal is depressed whether it is a ‘normal’ braking situation or an emergency stop.  In the event of an emergency stop, HBA automatically increases braking pressure, activating ABS and ensuring the level of braking meets the needs of the conditions.  The application of brake assist makes it possible even for unskilled drivers to reduce braking distances by 25 per cent.

Electronic Stabilisation Programme – ESP

This is a sophisticated system that automatically senses any tendency for the car to slide.  Should this situation occur, ESP reacts by applying the brakes to one, two, three or all four wheels and adjusts the engine’s power.  In this way, it is possible that a skid is corrected even before the driver is aware that one has started.  This can be useful if a tendency to understeer or oversteer develops in a bend.  In such circumstances ESP can help prevent the car skidding or spinning off the road and is particularly helpful in wet or icy conditions.    

Trailer stabilisation

This function greatly improves stability when towing by sensing the onset of a snaking motion and then neutralising it.  It is standard on all Touareg models fitted with a factory-fit towbar. 

This system extends the capability of the normal Electronic Stabilisation Programme purely through a software extension.  It does not require additional sensors.

When the onset of yawing of a trailer is detected by the ESP control module the system automatically reduces or cuts engine power and applies the brakes to appropriate wheels dynamically in phase with the yawing to oppose the snaking motion and stabilise the vehicle / trailer combination.  When stability is achieved the brakes and engine power return to normal control.  During the automatic braking process the brake lights are turned on even though the driver may not be touching the brake pedal. 

Rollover sensors

The Touareg’s ability off-road is boosted by the addition of new rollover sensors.  The system scrutinises vehicle acceleration, yaw angle and yaw speeds.  Should the system detect that a rollover is imminent the head / thorax airbags are automatically deployed to reduce the risk of injury.

Automatic Distance Control - ADC

Available as an option on Touareg, Automatic Distance Control (ADC) works in conjuction with the cruise control and the radar-based Front Assist distance monitoring systems.  Operated via buttons on the multifunction steering wheel, the system uses sensors to scan the road ahead for any dangers and can, if necessary, slow the vehicle to a complete halt.

The Front Assist system monitors the distance between other vehicles ahead and alerts the driver if a vehicle is too close, through a two stage warning.  An initial visual and audible alert is followed by a brief application of the brakes if no action is taken.  At the same time, the vehicle’s braking system is prepared for an emergency braking manoeuvre.

Side scan lane change assist

Side scan lane change assist monitors the ‘blind spot’ next to the vehicle and acts as a lane changing aid with an audible alert and a small warning lamp in the wing mirrors to warn of the danger of collision.

FACTORY-FIT OPTIONS

As befits a car of this class, there is an extensive range of optional equipment available for the Touareg.  This includes items such as Tiptronic gearchange controls mounted on the steering column; a boot-mounted six-disc CD autochanger; electric sunroof; powered tailgate closing; roof bars; a ski sack with load-through provision; side steps; and sunblinds for the rear screen and rear side windows.

Continuous Damping Control (CDC) air suspension

This feature is standard equipment on the V10 TDI and can be specified as an option on SE and Altitude models.  It ensures further comfort and, thanks to automatic speed-sensitive ride height adjustment, provides sporty dynamic characteristics while on the road as well as improved off-road handling.

Front and rear differential locks

As a further aid to off-road traction in extreme conditions, manually operated differential locks can be specified for the rear axle or for both front and rear axles. 

Navigation/radio/TV system

The satellite navigation system, standard on SE and Altitude models and an option on the entry-level Touareg, consists of a screen display housed in the dashboard which shows the required direction of travel, combined with verbal instructions.

Wheel sensors are used to determine the distance the car has covered and to provide information when the car is turning.  Further system components include a solid state magnetic compass and a GPS (Global Positioning System) aerial in the front left wing.  The aerial receives signals from orbiting satellites from which it is able to calculate the position of the car to within 100 metres.  A road map, effectively a digitised street plan of Great Britain or other country, is stored on DVD and is accessed by the on-board computer as it calculates the route required to reach the desired destination.

The range-topping navigation system also incorporates a television which, for safety reasons, operates when the vehicle is stationary and the handbrake is applied.  An entertainment pack with a DVD screen in the roof liner is also available.  

Keyless entry and start function

The keyless system is available as an option on SE and Altitude models with the auto Tiptronic gearbox.  With it, the driver need never remove the Touareg’s key from his or her pocket.  The car ‘recognises’ its driver via a transponder in the key, releases the lock when the driver touches the door handle and allows the engine to be started with the push of a button.

The system features several safety mechanisms.  For example, the Touareg will start only when the key is actually within the vehicle’s interior, and the driver must press the clutch or, on automatic models, the brake pedal.  On exit, the driver has only to touch the door handle once more to activate the automatic closing and locking procedure.  For security, the system only operates when the key is in close proximity to the vehicle.   

SAFETY

Volkswagen’s intention with the Touareg was to set the highest possible standards for active and passive safety, and to prove that the safety levels of a luxury saloon can be replicated in a luxury off-road vehicle.

The strength of the Touareg’s construction, its incorporation of the very latest in electronic safety features and the inherent stability of its four-wheel-drive and traction control systems raise standards to a significant new level.

Frontal collision

The Touareg was designed with very high frontal energy absorption characteristics and with an extremely rigid passenger cell, in line with both Euro NCAP and US crash legislation requirements.

Among the special protective measures adopted are additional strengthening bars in the sills, extremely rigid A-, B-, C- and D-pillars and the use of high quality steels in the construction, along with laser welding.

Side collision

The Touareg’s doors are integrated with the car’s crash protection structure, and are designed to afford passengers the maximum protection in the event of a side impact.

Passive safety

Touareg passengers benefit from a state-of-the-art electronic safety system featuring crash sensors which can judge the severity of an impact and react accordingly, triggering either a low-level response from the driver and front passenger airbags or a full-intensity response.

All models in the range feature driver and front passenger airbags, front side airbags and curtain airbags which cover the entire window surface between the A- and C- pillars to protect the heads and upper torsos of the window-seat passengers.

The Touareg also features electrically activated seat belt pre-tensioners to restrict passenger movement in an impact.  All models feature five three-point harnesses as standard.

The electronic safety system continues to work even after it has activated the airbags, automatically unlocking all the doors, isolating the battery, shutting down the fuel supply and all high-power electrical units, as well as switching on the hazard warning lights.

Child passenger protection

All Touareg models are equipped as standard with rear Isofix seat mounting brackets.  These are attached to the body of the car and allow a compatible Isofix standard child safety seat to be correctly installed with ease.  If small children are to be carried in a safety seat mounted in the front passenger seat, the front-seat passenger airbag system can be switched off. 

Pedestrian safety

The Touareg’s design team also gave careful consideration to minimising injury to pedestrians in the event of a collision.  Volkswagen does not offer a ‘bull bar’ for the Touareg and the car’s body design possesses a number of features which optimise protection for pedestrians and cyclists.  Among these is the construction of the bonnet in aluminium to provide optimum deformation characteristics, and the use of plastic materials for the wings.

Parking distance control is a standard feature of the SE V10 TDI and an option on other models.  This system features ultrasonic transmitters and receivers in the front and rear bumpers to warn the driver of obstacles; the front sensor can ‘see’ up to 1,200 mm and the rear sensor up to 1,500 mm.  If the Touareg approaches an obstacle it gives both an audible warning and a visual one, by means of a dashboard display and a roof-mounted display visible in the rear-view mirror.

Euro NCAP test results

In recognition of the Touareg’s safety features, the previous model was awarded a full five stars in the Euro NCAP (European New Car Assessment Programme) safety tests for adult occupant protection.  It scored four stars for child occupant protection and gained a one star pedestrian rating.  

SECURITY

All models in the Touareg range are fitted as standard with an electronic engine immobiliser and an alarm system with interior protection and remote central locking.  For added convenience and security, a keyless entry and start system is an option on automatic SE and Altitude models.  All Touaregs also feature an integrated factory-fitted CD/radio system which is Volkswagen branded and security coded.
