Audi won the Green Car of the Year award at the Los Angeles Auto Show with the A3 TDI, mostly on the basis of the car's 40 mpg fuel economy. But the cabin tech is a little behind other Audi models.
Due to low sulfur diesel at filling stations and more advanced emissions controls, diesel cars are making a small comeback in the U.S. Volkswagen, which owns Audi, is a major proponent of diesel cars, and won the Green Car of the Year award at the Los Angeles Auto Show with the A3 TDI.
The turbocharged 2-liter, four-cylinder diesel engine is also used in the Volkswagen Jetta TDI, which previously won the Green Car of the Year award. Its EPA mileage is 30 mpg city and 42 mpg highway. We saw an average economy of 38.5 mpg.
