VW?s BlueMotion is ramping up

Volkswagen?s European Passat with the optional 1.4L TSI EcoFuel is at first glance, a somewhat simple natural gas (NG) driven automobile. The fuel system and engine have been extensively reworked to operate on NG just as the Civic GX does here in the states. In addition however, the 1.4L TSI can also run on gasoline for both convenience and more range when a NG filling station is not available while providing both performance and economy never before achieved in a gasoline powered mid-sized automobile.
