If your wallet is taking a beating from high gas prices and all this talk of green energy has inspired you to shop around for a hybrid car, new fuel-efficiency ratings may help you.

The Environmental Protection Agency (EPA) has ranked 10 hybrid vehicles. Topping the list: the Toyota Prius, which gets 48 miles (77 kilometers) per gallon on city streets and 45 mpg (72 km) on the highway.

The Honda Civic Hybrid is next, racking up 40 mpg (64 km) for city driving and the same as the Prius on the freeway. No. 3 is the Nissan Altima Hybrid, which takes you 35 miles (56 kilometers) per gallon in the city, 33 miles (53 kilometers) per gallon on the expressway.


The Cadillac Provoq fuel cell concept uses GM's E-Flex propulsion system, combining the new fifth-generation fuel cell system and a lithium-ion battery to produce an electrically driven vehicle that uses no petroleum and has no emission other than water.

Powered by a 100 kW electric engine and fuel cell stack, the i-Blue is capable of running more than 370 miles per refueling and achieves a maximum speed of more than 100 miles per hour.

Based on the full-size 2007 Chevrolet Silverado 1500 HD pickup truck, the vehicle underwent extensive internal modifications to meet the technical demands and requirements needed to run on a compressed hydrogen fuel system.
