The Ford Escape Hybrid is a gasoline-electric hybrid powered version of the Ford Escape SUV developed by the Ford Motor Company, first launched in the U.S. in 2004, to offset the pollution resulting from non-hybrid SUV use. Built in Kansas City, Missouri, it was the first hybrid SUV to hit the market. A similar vehicle, the Mercury Mariner Hybrid is sold by Ford's Mercury marque. A third variation, the Mazda Tribute Hybrid, arrived in the fall of 2007 as a 2008 Model Year vehicle with a limited production run for the California market. The SUV got its first update (by not counting its 2008 redesign) in 2009 by changing the engine from 2.3L to 2.5L and badges. The Ford Escape Hybrid was the first American-built hybrid and the first hybrid vehicle from an American automaker, joining the Chevrolet Silverado/GMC Sierra Hybrids during the same model year. Hybrid versions can be identified by the "Hybrid" badges on the front driver's and passenger's doors as well as on the tailgate. Inaddition, the driver's side window in the cargo area is smaller in size in order to accommodate a ventilation slot for the high voltage battery.
