There are about five dozen hybrid or all-electric cars available in the U.S. Of those, the editors of Kelley Blue Book chose 10 that they think are the best of the bunch.

Generally speaking, a hybrid car uses mechanical means — like a regenerative braking system — to charge up relatively small batteries to give the car a higher mileage rating. A plug-in hybrid has to be charged up at an electrical outlet and once the charge is depleted, the car runs on gasoline or other liquid fuel. An all-electric car uses only plug-power and typically has large batteries.

With that in mind, here’s the Kelley Blue Book list, together with some comments on U.S. sales from hybridcars.com. All of the cars belong in model year 2013. For all-electric models, mileage is computed on a miles per gallon equivalent basis, where one gallon of gasoline is equal to 33.7 kWh of electricity.

10. Lincoln MKZ — Ford Motor Co. (NYSE: F)
Kelley’s editors say this hybrid car gets city/highway/combined mileage of 45/45/45. Ford sold 446 of these in the month of March and has sold a total of 723 to date in 2013.

9. Toyota Avalon – Toyota Motor Corp. (NYSE: TM)
According to Kelley’s editors the all-new hybrid Avalon gets city/highway/combined mileage of 40/39/40. Toyota sold 1,616 of these cars in March and 4,017 so far this year.

8. Honda Fit – Honda Motor Co. Ltd. (NYSE: HMC)
The Fit is an all-electric car with a range of 82 miles and gets city/highway/combined mileage equivalent of 132/105/118. Honda sold just 23 of the cars in the U.S. in March, and has sold only 46 so far this year.
