Kelley Blue Book, the United States' largest automotive vehicle valuation company, on Tuesday released a ranking to the top 10 "green cars" for 2010.

The top 10 "green cars" are Toyota Prius, Honda Insight, Ford Fusion Hybrid, Volkswagen Golf TDI, MINI Cooper, Ford Escape hybrid, Honda Fit, BMW 335d, Toyota Highlander hybrid and Chevrolet Tahoe hybrid.

The top 10 "green cars" must be fuel efficient for their class, and have relatively low carbon emissions, said Kelley Blue Book.

The annual rankings, timed to coincide with Earth Day on April 22, ranged from small cars -- efficient getting 51 miles per gallon (about 82 kilometers) -- to SUV hybrids capable of towing 5, 200 pounds at 22 miles (about 35 kilometers) per gallon.

"From conventional gasoline-powered fuel sippers to hybrids to diesels, we think car shoppers will be impressed with the variety in vehicle types and sizes, as well as the vast array of various technologies, available on the market for the green-minded consumer today, as showcased in our Top 10 Green Cars of 2010 list, " said Jack Nerad, executive editorial director for Kelley Blue Book.

Kelley Blue Book, based in Irvine, near Los Angeles, is a resource for prices, values and reviews on new cars and used cars.
