With its high-performance powertrain, the Volkswagen GTI could probably get away with lowest-common-denominator fuel economy. But it doesn't. In fact, it gets better gas mileage than the base engine in the mass-market Golf--a five-cylinder.
The EPA says for the 2011 model year, the manual-transmission GTI earns a rating of 21/31 mpg. Opting for VW's marvelous dual-clutch transmission boosts gas mileage to 24/33 mpg.
