Volkswagen’s green technologies

Volkswagen is presenting a package of environmental technologies including developments such as a new Stop-Start system, regenerative braking, electric drives and hybrid systems.

Touareg V6 TSI Hybrid: Volkswagen is set to present a prototype of the Touareg V6 TSI Hybrid. This promises 333 PS and over 31 mpg – which still isn’t great. The Touareg uses a parallel hybrid system, combining a 333 PS V6 TSI boosted by a supercharger and an electric motor (51 PS).  At speeds of under 50 km/h (31 mph), the Touareg V6 TSI Hybrid is powered by the electric motor alone and with zero emissions. This car is set to go into production in 2010 and will also be the world’s first hybrid SUV to have 3.5 metric tonne towing capacity.

Passat BlueMotion 2: A 2.0-litre 110 PS common rail TDI engine offers economy of 57.6 mpg and CO2 emissions of just 128 g/km while its range of 870 miles means it can travel from Land’s End to John O’Groats on a single tank of fuel. The Passat BlueMotion 2 has a Stop-Start system and conforms to the Euro V emissions standard. The Passat BlueMotion 2 is on sale in the UK now, priced at £17,327 for the saloon and £18,438 for the estate.

Passat BlueTDI: This 143 PS (105 kW) diesel engine is the first TDI to conform to the Euro VI emissions standard that does not take effect until 2014. The Passat BlueTDI has a SCR catalytic converter which reduces nitrogen oxides to less than 80 mg/km. Fuel economy of the saloon with a manual six-speed gearbox is 54.3 mpg (CO2 137 g/km); the Passat BlueTDI is also available in Estate bodystyle as well as with a six-speed DSG gearbox.

Passat TSI EcoFuel: Cars powered by natural gas have traditionally had poor performance, however the Passat TSI EcoFuel uses a turbocharged and supercharged direct injection engine configured for natural gas operation. With 150 PS, this Passat combines a top speed of 130 mph and a zero to 62 mph time of just 9.7 seconds with fuel economy of just 4.4 kilograms of natural gas (approx â‚Ź 4.25 in Germany) per 100 km. Thanks to a seven-speed DSG gearbox, the Passat achieves 120 g/km of CO2 (six-speed manual 4.5 kg/100 km and 123 g/km CO2). If the natural gas supply on board runs low, the Passat can be switched to run on petrol, giving a total range of around 560 miles.
