2008 Saleen S302E Mustang

From the article:

New for 2008, the car is affectionately known as the “Extreme” boasts a Saleen-built 302 cubic inch engine augmented by a patented Saleen twin-screw, intercooled supercharger. The combination delivers an unprecedented 620 bhp and 600 lb-ft of neck-snapping, tire incinerating torque… When married to a short throw, 6-speed manual transmission and Max-grip rear differential, the Extreme screams to 60 mph in less than 4 seconds and clicks through the quarter mile in just under 12 seconds… To get that kind of performance, the team had to get the S302E’s power to the ground. This is accomplished with standard 20-inch, 5 spoke forged aluminum alloy wheels wrapped in Pirelli P-Zero Rosso tires. Since power is nothing without control, the Extreme also features a Saleen Racecraft suspension and an all-new, second generation Watts Link system that is sure to help the driver maintain control through the corners.
