The second generation Escape Hybrid was offered in two levels of specification, an undesignated base model and the more expensive "Limited" trim. The base included: a 60/40 split-fold rear bench seat, AdvanceTrac with roll stability control, and a single-disc four-speaker CD/MP3 stereo with Sirius Satellite Radio compatibility. The "Limited" adds: a chrome front grille, heated front seats, a six-way power driver's seat and full leather upholstery, rear park assist, ambient lighting, and 16-inch six-spoke alloy wheels. For the 2009 model year, Ford SYNC became standard on both Hybrid trims and the Ford Escape Hybrid replaced the "ESCAPE" badges on doors with "HYBRID," while relocating the logo for Ford hybrid models from near the driver's side doors next to the "HYBRID" text. 2010 models saw the addition of MyKey, trailer sway controls, and integrated spotter mirror for better blind spot viewing. New optional extras are active park assist and a rear-view camera. Ford developed a prototype E85 Hybrid Escape, the first flexible fuel hybrid electric vehicle capable of running on 85% ethanol. In 2007 Ford produced 20 demonstration Escape Hybrid E85s for real-world testing in fleets around the U.S. From 2009, the gas engine was 2.5L Atkinson-cycle four cylinder engine with 155 hp at 6,000 rpm with an electric motor that produces 94 hp at 5,000 rpm. The maximum combined output of both was 177 hp. The U.S. Environmental Protection Agency (EPA) rated the fuel economy for the 2010 Escape Hybrid (FWD) at city, and highway. The following table compares fuel economy, carbon footprint, and petroleum consumption between the hybrid version and other drivetrains of the Escape family as estimated by the EPA and the U.S. Department of Energy. The Escape Hybrid met both California's SULEV and PZEV standards, with tailpipe emissions better than 90% less than the average 2003 new car and zero evaporative emissions. By early 2012 Ford discontinued the production of the Escape Hybrid due to the introduction of the third generation Escape. Two of the new 2013 model year Escapes have direct-injected and turbocharged EcoBoost units (of 1.6 and 2.0 liters) that deliver a higher fuel economy than the 2012 model. A total of 122,850 Escape Hybrids were built since 2005, along with 12,300 units of its sibling the Mercury Mariner Hybrid, discontinued in 2010.
