Volkswagen staged the world premiere of the all-new Touareg—which is up to 200 kg lighter and up to 20% more fuel efficient than the outgoing model—and the new Touareg Hybrid at the Postpalast in Munich. The new Touareg will offer a range of conventional gasoline and diesel engine options, an eight-speed transmission and, on the majority of models, Stop-Start technology.

The new Touareg Hybrid combines a 3.3-liter supercharged V6 direct injection gasoline engine producing 333 PS (328 hp, 245 kW) and 265 lb-ft (359 N·m) of torque; a hybrid module integrating a 47 PS (46 hp, 35 kW) electric motor and disengagement clutch; and an 8-speed automatic transmission. Total system output is 380 PS (375 hp, 279 kW) and 428 lb-ft (580 N·m) of torque; combined-cycle fuel consumption is 8.2 L/100km (28.7 mpg US), with CO2 emissions of 193 g/km.

The Touareg Hybrid attains a maximum speed of 240 km/h (149 mph) and accelerates to 100 km/h in 6.5 seconds.

Compared to a conventional SUV of the same size and power, the hybrid delivers more than 25% fuel savings in city driving. In combined mode driving, development engineers calculate an average savings of 17%. Essentially, four parameters were exploited to achieve this fuel efficiency on the Touareg Hybrid:

  • E-Motor: All-electric driving (up to 50 km/h / 31 mph) reduces gasoline 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, 99 mph), 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 recovers kinetic energy, which is then stored in the high-voltage NiMH battery pack.

  • Stop-Start System: The Stop-Start system integrated in the powertrain improves fuel economy, especially in urban areas and stop-and-go traffic.

The hybrid drive replaces the previous V8 gasoline engines in Europe and America and carries on Volkswagen’s downsizing strategy. Consequently, the V10 TDI and W12 engine versions of the previous model are no longer being offered.

The electric motor can operate independently of the combustion engine making the new Touareg a full hybrid. On electric power alone the new Touareg is capable of travelling at speeds of up to 30 mph (48 km/h). Alternatively the electric motor can supplement the V6 engine to provide a useful boost during overtaking manoeuvres and allows the Touareg Hybrid to accelerate from rest to 62 mph in 6.5 seconds before reaching a top speed of 149 mph (240 km/h).

Conventional drive. The entry-level engine and the likely volume seller is a 3.0-liter V6 TDI engine generating 240 PS (237 hp, 177 kW) and 405 lb-ft (549 N·m) of torque with fuel consumption of 7.4 L/100km (32 mpg US) and emitting 195 g/km of CO2.

A new 4.2-liter TDI V8 engine producing 340 PS (335 hp, 250 kW) and 590 lb-ft (800 N·m) of torque sits at the top of the new Touareg range. The new engine consumes 9.1 L/100km (26 mpg US) on the European combined cycle while emitting 239 g/km of CO2.

The 3.6L V6 FSI, a direct injection gasoline engine with 280 PS (276 hp, 206 kW), consumes 9.9 L/100 km (23.8 mpg US)—2.5 liters less than the previous engine version. This combined fuel consumption is equivalent to CO2 emissions of 236 g/km, 60 g/km less than before.

The overall length and wheelbase of the Touareg have each grown by 40 mm to measure 4,758 mm and 2,900 mm respectively. The width of the new Touareg remains as before at 1,928 mm while overall height drops by 20 mm to 1,724 mm.

The 20% increase in fuel economy is fine but it will not change the fact that the Touareg is still one of the most polluting vehicles in the VW collection. Hopefully in a few years VW will do a PHEV version with a 30 miles pure electric range or better at 70 mph and an EPA rating of 100+ mpg. That would be really exciting in my opinion. Admitted it would also likely add some 14000 to 18000 USD to the price of the car but it would at least give people and companies who can afford it a choice to drive large SUVs with a good conscience.

Can we have the hybrid system with the 1.2 TSI in the Scirocco?

Clearly a great need for these hybrid SUVs. Since global warming doesn't exist and we are entering a new ice age there will be a great demand for these all terrain vehicles just the thing to take your kids to their local school.

Isn't it a bit small and underpowered for larger-heavier USA family members?

No new technologies and no new batteries are needed to reduce fuel consumption for automobiles. People are trained to drive at high speeds on the Autobahn and motorways and to demand automobiles such as this one that have the horsepower to do it. For every car built and advertised, the advertised fuel consumption (8.2 L/100 km) should also be converted to average horsepower over the test cycle to show how overpowered and therefore inefficient vehicles such as this are. At 20% efficiency, very good for a large automobile engine, it would require 33.5 gallons per hour to operate this engine at 245 kW. Wikipedia shows 36.6 kWh/US gallon, but this is thermal and not electrical energy. This power could supply electricity to 300 German dwellings. Obviously all automobile engine operate at a small fraction of their available rating and an even smaller fraction of their advertised rating. The Citroën 2CV car, ("2 horse power") indicates how low an average power is actually needed to operate a vehicle in the city for useful transportation "The car would use no more than 3 litres of gasoline to travel 100 km (78MPG)". The first vehicles sold seem to have had about nine horsepower available. The TATA NANO will put many Indians into automobiles as the 2CV did French people and the Model T did Americans and the Volkswagen did Germans. There are very few people who would refuse the use of a loaned Volkswagen Beetle to replace a failed Mercedes just to finish the daily commute to work.

In fact it is now time to convert all automobile production to full electric transmissions and then automobile engine-generators can be used to to supply massive ammounts of grid power when needed. The stationary automobiles can be directly connected to the Natural gas supply system for fuel. The induction motor-generators and power electronics developed by AC Propulsion is well suited for this type of operation. The problem is that it would require a very large transformer and heavy cables to put this much power into the grid.

There is a similar problem for fast charging for full electric vehicles, which is best done with large natural gas fueled engines if done at all, and the electrical grid can be spared the sudden jolt equivalent of 300 electric cookers suddenly connected in one appartment block.

Full electric transmissions can reduce the size of engine needed for fast acceleration substantially and thus allow the use of more efficient smaller engines as is done in diesel electric locomotives to accelerate large trains. Electronics now allow the use of simple cheap induction motors and generators and not a single gram of high performance permanent magnet material needs to be used. Copper wire to copper wire connection without electronic conversion can be used at Autobahn speeds for slightly higher efficiency. Autobahn speeds; however, exclude any possibility of meaningfull efficiency. ..HG..

BMW's answer to a question no body asked, has engendered from VW, a modern version of the BMW antiquated, guzzling, heavyweights.

A small to mid size 'sports car SUV', with minimal carrying capacity, and poor sports-car, or good SUV handling, take your choice. It remains a mish-mash of conflicting ideas.

But at least the mileage with hybridization, is respectable. With a 20-30 miles PHEV battery, this could still obtain high 90+ if not triple digit fuel economy.

But it still remain an answer to a question NOBODY asked.
