2003 Saleen S7

The 2003 Saleen S7 is a hand-built, high-performance American supercar. It was initially powered by a naturally aspirated 7.0L Ford Windsor V8 engine producing 550 horsepower and 525 lb-ft of torque, paired with a 6-speed manual transmission. Later models featured a twin-turbocharged version of the same engine, significantly boosting power. Owners often praise the S7 for its striking design, exclusivity, and incredible performance. Common criticisms include its high cost of ownership, limited practicality, and challenging driving characteristics at the limit.
