2011 Volkswagen Golf TDI | 34 mpg (30 city/42 highway)
Interested in saving the planet but don't want to stop having fun? The punchy, sticky, miserly Golf TDI just might be the instrument of good you seek. We're long-time fans of the Volkswagen Golf lineup for its European driving feel, hatchback utility and interior quality that outclasses anything else in its class. When outfitted with the automaker's ubiquitous 2.0-liter turbo-diesel engine capable of delivering quick launches and 42 highway miles per gallon, you can feel especially good behind the wheel.
