Audi A3

For drivers wanting utility and luxury in a smaller, greener package, the A3 fits the bill. The "Sportback" 5-door body style offers the spaciousness of an SUV on a platform shared with its Volkswagen cousins the Golf and Jetta. The TDI clean diesel engine is capable of 42 mpg on the highway, according to the EPA, but the direct-inject gasoline engine gets 28 mpg on the highway itself. High-end touches such as leather seating and a 10-speaker stereo are standard equipment on both Premium and Premium Plus trim levels.
