The Saleen S5S Raptor is a concept car revealed by Saleen on March 20, 2008 at the 2008 New York International Auto Show.
The S5S Raptor was designed in 2007 at the ASC design studio in Metro Detroit, and is intended to be equipped with a 5.0 L (310 cu in) supercharged Saleen engine (similar to that used on the 2008 S302E) which will yield 650 hp (660 PS; 480 kW). This will allow it to accelerate to 60 mph (97 km/h) in 3.2 seconds or less and complete the quarter-mile in 10.9 seconds. Expected retail price is US$185,000, roughly US$400,000 less than the S7.
