The 2010 Audi A3 TDI was named Green Car of the Year at the LA Auto Show today, giving the Germans and clean diesel technology back-to-back wins. The four-door hatchback, which has a base sticker price of $29950, “offers it all,” said Ron Cogan, publisher of Green Car Journal, which sponsors the annual award, praising the car’s sporty performance and superior fuel economy. Consecutive victories by clean-diesel technology over gas-electric hybrid cars gave Johan de Nysschen, president of Audi of America, an opportunity to wag a finger at Washington policymakers who have fallen in love with hybrid and all-electric technology. The A3 TDI is powered by the same engine as last year’s Green Car of the Year, the VW Jetta TDI. Audi is owned by Volkswagen.
