Ford Escape Hybrid

Hybrid versions can be identified by the "Hybrid" badges on the front driver's and passenger's doors as well as on the tailgate. In addition, 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. There was also a "Special Appearance Package" available as an option on the 2004-2007 Hybrid models. This package replaced the traditional lower cladding of the Escape with a silver finish.

The Escape hybrid is a "full" hybrid electric system, meaning the system can switch automatically between pure electric power, pure gasoline engine power, or a combination of electric battery and gasoline engine operating together, for maximum performance and efficiency at all speeds and loads. When braking or decelerating, the Escape's hybrid system uses regenerative braking, where the electric drive motor becomes a generator, converting the vehicle's momentum back to electricity for storage in the batteries. With 155 horsepower (116 kW), the Hybrid Escape has nearly the same acceleration performance as the conventional 200 hp (150 kW) V6 Escape.

Ford built 17,000 Escape Hybrids in the second half of 2004, four times as many as it had originally planned, and sales figures have remained steady.

Toyota, launched two hybrid SUVs in 2005, a version of their Highlander, and a Lexus-badged RX 400h, both of which outsold the Escape hybrid in 2006, their first full year of sales. A number of Mazda Tribute Hybrids have also been produced.

Ford announced the development of a prototype Hybrid Escape E85, the first hybrid vehicle capable of running on 85% ethanol flexible fuel, although they have not announced any production plans.

The Escape Hybrid uses technology similar to that used in Toyota's Prius. Ford engineers realized their technology may conflict with patents held by Toyota, which led to a 2004 patent-sharing accord between the companies, licensing Ford's use of some of Toyota's hybrid technology in exchange for Toyota's use of some of Ford's diesel and direct-injection engine technology.  Both Ford and Toyota state that Ford received no technical assistance from Toyota in developing the hybrid power train. Aisin Seiki Co. Ltd., a Japanese automotive components supplier belonging to the Toyota Group, supplies the hybrid transmission for the Escape Hybrid. While Toyota produces its third-generation Prius transmission in-house, Aisin is the only supplier of hybrid transmissions to other manufacturers. Friction has arisen concerning Aisin's allocation of limited production capacity and engineering resources to Ford.

Ford announced on July 9, 2007 that it will team up with Southern California Edison (SCE) to examine the future of plug-in hybrids in terms of how home and vehicle energy systems will work with the electrical grid. Under the multi-million-dollar, multi-year project, Ford will convert a demonstration fleet of Ford Escape Hybrids into plug-in hybrids, and SCE will evaluate how the vehicles might interact with the home and the utility's electrical grid. Some of the vehicles will be evaluated "in typical customer settings,"according to Ford.
