2011 Volkswagen Touareg Hybrid

(from VolksWagen press-release)

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.
