Volkswagen is leading the push for diesel in the U.S. with the Jetta and Touareg, the latter being an SUV running a 3-liter turbocharged diesel engine. Fuel economy isn't stunning, but it's better than the gasoline equivalent.
Volkswagen uses its diesel technology extensively in Europe, but has been barred from selling diesel cars in many U.S. states because of emissions regulations. New technology to clean up these emissions has opened up the market for Volkswagen.
The Touareg is Volkswagen's biggest SUV. Unlike SUVs from U.S. automakers that are largely derived from trucks, the Touareg's curved lines give it a more modern look. It also uses an independent suspension, but still has rugged characteristics.
