The Volkswagen Passat
EcoFuel recently edged out the Toyota Prius
for the title of "greenest car in Europe." The International Automobile Federation (FIA
) sanctioned the Eco Test that evaluated a number of cars. The winning Passat
is powered by a 1.4-liter TSI inline-four fueled by natural gas
TSI engines are turbocharged and direct injected.
Both the Passat and Prius
scored 92 out of 100 on the test, but the less expensive natural gas fuel system gave the VW the edge. The test evaluated emissions of CO2
, carbon monoxide, nitrogen oxides and hydrocarbons. The EcoFuel TSI engines are available in many of VW's European models including the Golf
, Touran and others.
