As the smallest Audi, the 2013 A3 is relatively fuel efficient. But its the TDI turbodiesel variant that really delivers the goods, with a combined 34-mpg EPA rating that many owners say is lower than their real-world daily average. It's made up of a 30-mpg city rating and a remarkable 42 mpg on the highway.
Our editors once logged 45 mpg in steady highway use, an almost unthinkably high number for a German luxury vehicle that holds four people. In steady stop-and-go traffic, we saw 30 mpg and better.
The regular 2.0-liter turbo gasoline engine is rated at 24 mpg combined when ordered with the S tronic dual-clutch gearbox and front-wheel drive. The quattro all-wheel drive option cuts your city mileage by only 1 mpg, so there's very little penalty for the improved performance and safety of powering all four wheels.
