New Touareg takes the SUV idea into the future
Touareg debuts with hybrid drive and high-tech range of engines Volkswagen SUV is 208 kilograms lighter and 20 percent more fuel efficient
Wolfsburg/Munich, February 2010. Today, Volkswagen is unveiling the completely redeveloped Touareg as a world premiere. It is the most technically innovative “VW” since the brand has been in existence. This Touareg is reinterpreting the fascinating multipurpose SUV idea in a contemporary way – thanks to a range of engines that are nearly 20 percent more fuel efficient and a large variety of new assistance and safety systems. The Touareg will also be the first and only off-roader in Europe by a German car maker to be available in a hybrid version too. It sets standards among fully off-road capable SUVs with petrol engines that have a fuel consumption value of just 8.2 litres fuel per 100 kilo metres. The Touareg Hybrid can be driven up to 50 km/h in purely electric mode - emissions-free. Among the diesel engines, the Touareg V6 TDI with 7.4 litre combined fuel consumption now posts the best value in the segment of genuine SUVs. Both versions, the Touareg Hybrid and V6 TDI, are the most fuel efficient petrol and diesel SUVs ever built in Europe in this large vehicle class.
New era SUV – lighter, more aerodynamic and fuel efficient
As has already been accomplished on the globally successful, smaller Tiguan, Volkswagen is systematically striving for sustainability on the new Touareg too. The first precondition was met: The SUV was lightened by 208 kilograms in the base version! A quantum leap. Yet, the body has five percent greater torsional rigidity, which makes it the leader in its competitive class. A second precondition was met as well: Designers attained a significantly improved Cd value. Along with aerodynamic refinement efforts, another factor at work here is that this Touareg is built lower to the ground than the previous model. Together with front end styling based on the new Volkswagen design DNA, this results in a smaller frontal area. The third precondition: All engines, now offered with a standard 8-speed automatic transmission – a first in this market segment – demonstrate significant fuel economy advantages over the previous model; in some cases the advantage is far greater than two litres per 100 kilometres.
SUV for all trails – All-wheel drive in two versions
Also modified in pursuit of reduced fuel consumption was the standard all-wheel drive. In the base version (“4Motion”), all new generation Touaregs have all-wheel drive with Torsen limited-slip differential (4MOTION; climbing ability: 31 degrees). Like the Tiguan Track & Field, the Touareg also has an “Off-road driving programme”, which - at the press of a button - tunes the ABS, EDS and ASR for off-road duty, activates Hill Descent Assist and adjusts the automatic gearshift points.
Instead of a Torsen differential, the V6 TDI can be ordered with an optional “Terrain Tech Packet” that has an even more rugged transfer case designed for off-road duty. It includes reduction gearing and centre and rear differentials, each with up to 100 percent locking (4XMOTION; climbing ability: 45 degrees). Similar to the first Touareg generation, this version also has a rotary switch the driver now uses to adapt the car to specific duty conditions over five levels: 1. “On-Road”; 2. “Off-Road” (like “Off-road driving programme” plus automatic control of the mechanical locks); 3. Low (like “Off-road” plus activation of reduced gearing, higher shift points, no automatic upshift in manual mode); 4. Addition of centre differential lock; 5. Addition of rear differential lock. Equipped like this, the Touareg can conquer any terrain on Earth.
SUV for everyday driving – more space, more innovations
Volkswagen has not only made the new Touareg lighter, more fuel effi cient and an agile performer; it has also made it into an even more versatile, all-round vehicle. The new interior was made more functional, the seats more comfortable and leg room in the rear is larger. Now the rear bench seat has 160 millimetres in longitudinal adjustment, and the backrest angle can be adjusted. Electrically unlatched at the press of a button as an option, it folds down in seconds and frees up 1,642 litres of cargo space. Already standard equipment in the base version is a radio- CD and info system, which is intuitively controlled over a 6.5-inch touch-screen.
The parking brake is now activated by pushbutton. The engine (V6 versions) automatically shuts off at traffic lights and restarts as soon as the driver releases the brake pedal (Stop-Start system). As an option, the tailgate can be opened and closed by a RF remote control unit inte gra ted in the car key. The largest panoramic sunroof of all SUVs provides for light even on overcast days. The innovative “Area View” utilises four cameras to detect the Touareg’s surroundings and this enhances safety. Also offering protection are up to nine airbags. Lane Assist ensures that the vehicle does not stray from the right path; meanwhile, Side Assist warns of vehicles approaching from the rear when changing lanes. Adap tive Cruise Control (ACC) with integra ted Front Assist can brake to a stop in an emergency and tension the seat- belts as a precautionary measure. Bi-Xenon headlights with Dynamic Light Assist perceive oncoming traffic and adjust the light beam to eli minate unwanted glare, and adaptive roll compensation ensures that the Touareg sits solidly on the street. For the first time, there will be special features on the new Touareg under the new “Exclusive” badge from Volkswagen Individual. Options that can be ordered include 19-inch alloy wheels (“Girona” type), fine wood inserts (“Olive Ash”) and a leather interior (“Nappa”) in the two-colour combinations “Dark Burgundy/Titan Black” or “Pepper Beige/Titan Black”.
Touareg – the best of two worlds
About 500,000 car drivers chose to buy the first generation of the SUV. It is a luxury sport utility vehicle that offers a high level of comfort, sporty driving properties, avant-garde styling, excellent quality and unlimited expedition capabilities – essentially the best of the passenger car and off-road worlds unified in one concept. This is now being followed up by the new Touareg – a high-end and versatile all-round vehicle that brings these two worlds together even more perfectly. The Touareg will already be available at dealers in April.
Drive Concepts FSI/TDI/TSI/Hybrid:
New hybrid petrol engine, new V8 TDI, extremely fuel-efficient V6 TDI
Touareg Hybrid with V6 petrol engine replaces V8 petrol in many countries V8 TDI outputs 800 Newton-meter torque; V6 TDI has 7.4 litre fuel consumption
Wolfsburg /Munich, February 2010. The new Touareg is the first Volkswagen and SUV from Europe that will be available in a Hybrid version. With its combined fuel consumption of just 8.2 l/100 km the Touareg Hybrid sets new standards among full-fledged SUVs with petrol engines. Naturally, its CO2 emissions are low too: 193 g/km. The hybrid drive as the top powertrain option combines the power of a classic eight cylinder engine with the fuel economy of a six or four cylinder engine. It replaces the previous V8 petrol engines in Europe and America and carries on Volkswagen’s successful downsizing strategy. Consequently, the V10 TDI and W12 engine versions of the previous model are no longer being offered either.
Key components of the Touareg Hybrid powertrain - equipped with a high-voltage battery - are its supercharged V6 TSI (petrol direct injection engine with 245 kW/333 PS), 8-speed automatic transmission - ideally suited for hybrid and towing duty - and the hybrid module that is integrated between the internal combustion engine and the automatic transmission. This compact module with disengagement clutch weighs 55 kilograms. Located downstream of the V6 TSI, it integrates the disengagement clutch and E-Motor (34 kW/47 PS) in one housing. When the V6 TSI and E-Motor work simultaneously (boosting), a total power of up to 279 kW/380 PS is generated with a maximum torque of 580 Newton-meter as measured on the dynamometer.
Volkswagen has chosen a parallel hybrid drive configuration for the Touareg. In contrast to other potential hybrid systems, it assures excellent off-road performance and unlimited continuous climbing ability. With a maximum trailer payload of up to 3.5 tonnes, the Touareg is also an ideal towing vehicle, even in the hybrid version. Moreover, the parallel hybrid is more efficient than alternative hybrid concepts on long-distance and freeway journeys. The Touareg Hybrid attains a maximum speed of 240 km/h and accelerates to 100 km/h in just 6.5 seconds.
Compared to a conventional SUV of the same size and power, the hybrid concept delivers over 25 percent fuel savings in city driving. In combined mode driving – a mix of city, highway and freeway drives – development engineers calculate an average savings of 17 percent. Essen tially, four parameters were exploited to achieve this fuel efficien cy on the Touareg Hybrid:
- E-Motor: Electric, emission-free driving (up to 50 km/h) reduces petrol consumption. In this case, the V6 TSI is not only shut off, but is also disengaged from the 8-speed automatic by a disengagement clutch to avoid drag torque losses.
- Coasting: As soon as the driver releases the accelerator pedal, the V6 TSI is disengaged from the transmission. This is even possible at higher speeds (up to 160 km/h), i.e. on the freeway as well. The Touareg “rolls” significantly longer, since drag torque losses are eliminated. When drivers adopt an anticipatory style of driving, this has a direct and positive impact on fuel economy.
- Regenerative Braking: During braking, the E-Motor - now operating as a generator – recovers kinetic energy, which is then stored in the high- voltage battery (NiMH battery).
- Stop-Start System: The Stop-Start system integrated in the powertrain improves fuel economy, especially in urban areas and stop-and-go traffic.
Efficient Trio – V6 FSI, V6 TDI and V8 TDI
Fuel economy and emission values are also significantly improved on the conventionally powered Touareg versions. Consider the V6 FSI, a direct injection petrol engine with 206 kW /280 PS: At 9.9 l/100 km, the 3.6-litre engine with 360 Newton-meter torque now consumes an in credible 2.5 litres (!) less than the previous engine version. This combined fuel consumption is equivalent to CO2 emissions of 236 g/km. And that is precisely 60 g/km less than before.
The diesel engines were made more fuel efficient as well. An advanced version of the successful V6 TDI that still outputs 176 kW/240 PS (European version) is being offered right at market launch; it offers entry into the world of the Touareg; the 550 Newton-meter strong turbo-diesel consumes a ground-breaking low 7.4 l/100 km (analogous to 195 g/km CO2), which is 1.9 litres less than before. CO2 emissions are reduced by 49 g/km compared to the previous Touareg V6 TDI and by a respectable 24 g/km compared to the previous version with BlueMotion Technology that already had very good values.
Entirely new to the Touareg programme is a V8 TDI with 4.2 litre displace ment and 250 kW/340 PS. Considering its power and fabulous maximum torque of 800 Newton-meter, the combined fuel con sumption of 9.1 l/100 km (equivalent to 239 g/km CO2) is extremely good. This TDI is not offered in the USA. In some cases, the engine range will be country-specific in terms of the diesel and petrol engines offered.
