VW

Like several other manufacturers that sell cars in Europe, Volkswagen has a growing lineup of vehicles that run on natural gas and liquid petroleum gas (LPG), or autogas as it is commonly called in Europe. The newest models are the Golf BiFuel and Passat TSI EcoFuel.

The Golf BiFuel uses a 97 horsepower, 1.6-liter four-cylinder engine that can run on either gasoline or LPG. Autogas is readily available throughout Europe, and Germany alone has about 4,500 LPG filling stations. Drivers of the BiFuel VW can chose to run on either LPG or regular gasoline using a simple switchover system.
