VW to Introduce Passat BlueMotion at Geneva; Planning a New Compact Car
10 February 2007
Volkswagen will unveil a BlueMotion version of the Passat at the Geneva Motor Show in March. BlueMotion represents the most efficient and economical vehicle in each of Volkswagen’s car ranges.
VW introduced the first and so far only BlueMotion model, the Polo BlueMotion, at the Geneva show in 2006.(Earlier post.)
The Polo Bluemotion uses a modified version of the 3-cylinder 1.4-liter TDI diesel engine in the conventional Polo to produce the same power output—59 kW (79 hp)—and torque—195 Nm—but with a reduction in fuel consumption of 11% (0.5 liters/100km) to 3.9 liters/100km (60 mpg US). Emissions of CO2 drop by 13% from 119 g/km to 102 g/km.
The Bluemotion TDI engine is fitted with electronically controlled, high-pressure direct injection. A variable geometry turbocharger is added to provide high levels of torque from just above idling speeds and improve responses. The modifications increase the engine’s output and overall efficiency to allow greater performance while simultaneously using less fuel.
Other factors contributing to the increased efficiency are longer gear ratios (gears three to five have 12% to 24% longer ratios) and the aerodynamic design of front and rear spoilers.
Separately, new VW CEO Martin Winterkorn told the Sueddeutsche Zeitung that he has proposed the development of a new, very small model beneath the Fox.
He described it as an economical small car that would have space for four people, plus luggage.
In the article, he also said that VW would produce hybrid drivetrains for compact-class cars. An article in Automobilewoche in January reported that Volkswagen was modifying its hybrid strategy to concentrate first on an application for the Touareg, rather than on a smaller car such as the Jetta.
