2011 Volkswagen Jetta TDI

Cost: $22,995
Fuel economy: 34 mpg (6-9 better than the gas engine)
Annual fuel cost: $1,411
Annual CO2 emissions: 6.2 tons

Restyled for 2011, this compact hatchback is among the Volkswagen clean diesels, and at 34 mpg, it achieves impressive fuel economy, but still with more emissions than a comparable gas engine.

The Jetta is Good Housekeeping's pick for best fuel-efficient diesel car, calling the Jetta a "no-frills, smooth-handling fuel-efficient option, particularly if you do a lot of highway driving."
