If 500 ponies weren't enough, the power mavens at Saleen have upped the ante to 750 horsepower and 700 lb-ft of torque for the new 2005 Saleen S7. Saleen has made numerous changes to its American supercar in order to capture increased sales and bragging rights as the best -- or at least the fastest of the best. Lined up side by side with the original S7, you'd be hard pressed to notice differences such as the new diffuser/rear spoiler or the reshaped front fenders. The chassis was also reengineered with revised suspension pickup points and geometry in the name of improved performance dynamics with increased comfort. Engine updates are extensive to accommodate ball-bearing twin-turbochargers packing 5.5 psi of max boost pressure. Saleen claims 2.8 seconds from 0-60 mph and a 10.7-second quarter mile time, which would rocket it to the head of the exotic car class.
