The Ford Escape Hybrid and Mercury Mariner Hybrid are the gasoline-electric hybrid powered versions that launched in the U.S. in 2004 for the 2005 model year. Assembled in Kansas City, Missouri, it was the first hybrid SUV produced for sale and the first hybrid from an American manufacturer (alongside the Chevrolet Silverado/GMC Sierra Hybrids during the same model year). According to the Environmental Protection Agency, the first-generation Ford Escape Hybrid is 70% more efficient than the regular Escape. While the Mercury Mariner was also offered as a hybrid, the option was not available on the Mazda Tribute.
