The Saleen S7 is a supercar manufactured by Saleen.
Developed jointly by Steve Saleen for the initial concept, direction and engine, Hidden Creek Industries for resources and initial funding, Ray Mallock Ltd. (RML) for chassis, suspension and aerodynamics, and Phil Frank for the body and interior CAD design and development.
It was the first fully proprietary car produced by Saleen and became America's third mid-engine production sports car coming after the Vector W8 and M12. The S7 debuted on August 19, 2000 at the Monterey Historic Races. The all-aluminium engine is a bored-and-stroked derivative of Ford's 351 Windsor small block with Cleveland-style canted valve heads, not based on the FE big-block. It proved remarkably tractable and flexible for a high-output requirement—550 hp (410 kW) at 6,400 rpm. In 2005, the S7 gained a more powerful twin-turbocharged powerplant which boosted engine power to 750 hp (559 kW) and top speed to 248 mph (399 km/h).
The chassis uses a space frame-derived design consisting of 4130 lightweight steel and aluminium honeycomb composite reinforcing panels. It is divided into bolt-fastened sub-assemblies to allow for rapid access to critical subsystems. This design contributes to the car's light overall weight of 2,865 lb (1,300 kg).
The naturally aspirated version of the S7 is able to accelerate from 0–60 mph (97 km/h) in an estimated 2.8 seconds, and to 100 mph (161 km/h) in an estimated 7.1 seconds. It completes a standing 1⁄4 mile (402 m) in an estimated 11.35 seconds, reaching 128 mph (206 km/h). Top speed is an estimated 220 mph (354 km/h).
