13 great fuel-efficient cars

Kelley Blue Book names cars in every category that save fuel without sacrificing very much else.

Mercedes-Benz E320 Bluetec
Luxury sedan
Mercedes-Benz E320 Bluetec
Fuel economy: 23 mpg City / 32 highway (Based on new EPA rating methods.)

Powered by an advanced diesel engine, the E320 Bluetec is as smooth and pleasant to drive as you'd expect from a Mercedes-Benz.

Unfortunately, due to ultra-strict emissions regulations in some states - among them California and New York - the E320 isn't for sale everywhere in the U.S. For now, it's available on a special two-year lease in California. That deal will be available in the other diesel-restricted states soon.

After that, a new super-clean E320 should be for sale everywhere.
