The 2011 Audi A3 is a sporty hatchback, but Audi certainly hasn't forgotten how shoppers for this type of vehicle value fuel economy more than just the dent it might put in their budget. With either engine, fuel economy is better than average, but it's downright excellent with the TDI; EPA ratings are 30 mpg city, 42 highway with the S tronic automatic, and our editors have seen more than 45 mpg in long-haul interstate cruising and even low 30s in stop-and-go situations.
In 2015, Volkswagen admitted diesel engines in this model illegally cheated federal tests and polluted beyond allowable limits. As part of unprecedented settlements with federal and state governments, Volkswagen agreed to buyback from owners diesel-equipped models of this vehicle. To determine eligibility for all affected Volkswagen, Porsche, and Audi models, Volkswagen set up VWDieselInfo.com for owners. (Owners of affected vehicles can enter their VIN numbers to see if their cars are eligible for buyback.)
Standard 2.0T turbocharged gasoline versions of the A3 also get pretty impressive mileage, with figures of 21 or 22 in the city and 28 or 30 on the highway.
