The 2007 to 2009 Saleen S281 and S302 was a conversion based on the Fifth Generation Ford Mustang that featured a 281ci (4.6L V8) or 302ci (5.0L V8) performance engine, upgraded suspension components, and unique exterior and interior styling. Multiple trims were offered but not limited to the 3V, S/C, and Parnelli Jones. The coupe or convertible bodies featured aero bumpers, HID headlights, grills, hoods, and spoilers. The interior commonly featured multi-colored upholstery and unique trim treatments. Different styles of suspension components were used to improve on the Fifth Generation Mustang the vehicles were based on. The Saleen engines featured modified internals and an optional supercharger. Power was sent to the rear wheels via a five or six speed manual or four or five speed automatic transmission with a limited-slip rear differential. 4,669 S281 and S302 were produced, and they were succeeded by the 2010 facelift Saleen Mustang II.
