5) Saleen S7
The S7 is Saleen’s flagship car. It debuted in the year 2000 and became America’s first mid-engine supercar in production. The S7 was built from the ground up as a race car and was hand crafted. Among the car’s several innovative elements are its space frame design and an all-aluminum small block engine derived from a Ford V8 design. The engine was unusually light and powerful, producing 550 hp at 6400 rpm.
In keeping with its race car legacy the S7 has competed in the American Le Mans Series (ALMS), the 12 Hours of Sebring and the FIA GT Championship. To its credit the racing version of the S7 achieved a podium finish in its class at the 24 Hours of Le Mans.
The original S7 had a naturally aspirated engine and could theoretically reach 0 to 60 mph in 3.3 seconds. Its top speed was estimated at 220 mph. Track tests were not performed to verify these estimates. An updated version of the S7 was introduced in 2005 and sported a twin turbocharged engine with a power output of 750 hp, and a top speed of 248 mph (399 km/h).
