Mazda Tribute HEV

Launched in summer 2007, the Tribute HEV is Mazda's first mass-market hybrid, a gas-electric version of the Tribute SUV. The Tribute HEV is powered by a four-cylinder gas engine and battery pack, which combine to produce 155 horsepower while meeting two U.S. industry ratings for low-emissions cars, PZEV (partial zero-emissions vehicle) and SULEV-II (super ultralow emissions vehicle).
