|  The Shelby GT500 was displayed at the Detroit Auto Show, which really supercharged the public's desire for its release in 2007. The reason why the entire world is so wound up about the 2007 GT500 is because is boasts 475 horsepower from a supercharged 5.4L 32 liter V8 and a six speed manual transmission. With all of these bells and whistles it's no wonder the 2007 GT500 Ford Shelby will possibly be the best selling Mustang ever.
The Shelby's supercharged 5.4-liter, 32-valve V8 is similar to the engine in the GT. Ford started with the cast-iron 5.4-liter Triton V8 truck engine and added aluminum heads from the GT, specially calibrated camshafts, a Roots-type supercharger making 8.5 pounds of boost, and a water-to-air intercooler.
Under that blower is an all-new low-profile intake manifold, which allows the engine to fit under the GT500's special air-extraction hood. Fuel comes from a dual-bore electronic throttle body borrowed from Ford's 6.8-liter truck engine program, however, the larger radiator, increased-capacity cooling system and the exhaust manifolds are unique to this application. This super-car is standard equipped with a six-speed performance gearbox that helps deliver an evenly distributed torque curve and optimum power via precise gearing ratio. The heavy-duty transmission is more than adequate to handle the enormous power transfer to the rubber on the road. It has been tested and proven in track competition as well as day-to-day street driving. In the 2005 Mustang FR500C, this racing chassis and suspension rose to the occasion by clinching the Grand-Am Cup series. Needless to say, this makes the 2007 Mustang Shelby Cobra GT500 the best handling high performance vehicle on the road today.
The upgraded chassis and suspension features improvements in many components including shocks, stabilizer bars and spring rates. The independent front suspension boasts genuine MacPherson struts and reverse type lower control arms. It also boasts large 34-mm tubular stabilizers. The three-link solid axle rear suspension is equipped with a Panhard rod for precise rear axle action with coil springs and a 24-mm solid stabilizer bar. The brakes are some of the largest ever designed for a performance vehicle. They feature four wheel power discs: Brembo 14-inch vented, crossed drilled with four-piston calipers up front and thirteen inch vented, crossed drilled with two piston calipers on the back wheels. This combination has set itself apart from the rest of the field as great power requires great control. The Shelby GT500 features very large wheels: 19 by 9 1/2 inch machined aluminum, which accommodate P255/45R19 racing performance tires. The interior is completely wrapped in ebony black leather, including the top of the dash, door panels and center armrest. The red leather inserts are an SVT exclusive. The audio is a 1000-watt Shaker system with AM/FM, a six-disc CD/MP3 player in the dashboard and Sirius satellite radio.
