When in 2002 S7 went on sale, it was the only street-legal car in the United States that has more than 500 horse power output and 500 lb-ft of torque. S7 Twin-Turbo is the successor of the already legendary supercar S7. Like in any other true supercar, the doors of Saleen S7 Twin-Turbo open upward and away from the body. It features an even more powerful all-aluminum V8 engine, which produces 750 horse power @ 6300 rpm and 700 lb-ft of torque. Redline is at 6500 rpm. 2006 version of Saleen exotic car also has one unique interior feature - a video rear-view mirror. There actually is a small video camera mounted in the rear of the fast car, which transmits the view to the driver. The main idea here was not to use standard rear-view mirrors in favour of aerodynamics, thus reducing aero drag and increasing down force.
