The Ford Mustang: It's a name that carries a lot of respect. Combine it with the name of legendary car designer Carroll Shelby, and you've got the makings of a truly great American car. The Ford Shelby Mustang GT500 isn't just another souped-up Mustang -- it's the most powerful Mustang to ever roll off a factory production line.

In this article, we'll find out what sets the GT500 apart from other Mustangs.

The Ford Shelby Mustang GT500 is a car that follows a distinctly American approach to high-performance -- give it lots of horsepower and then get out of the way. There are some important differences between the GT500 and the "plain" 2005 Ford Mustang. The 2005 Mustang sports a 4.0-liter SOHC (single overhead cam) V6, which puts out 210 horsepower, and the GT version comes with a V8 capable of 300 horsepower. The GT500 is rated at 500 horsepower.

It all starts with a 5.4-liter DOHC (dual overhead cam) V8 engine made of cast iron, a powerplant first used in the limited edition Mustang Cobra R.

A screw-type supercharger with an air-to-water intercooler, generating 9 pounds of boost, forces air into the cylinders, each of which has four valves. Many of the engine components, such as the aluminum piston heads and bearings, came from the development of the Ford GT. A T56 six-speed manual transmission is also part of the GT500's powertrain, but there's no technological innovation here. The T56 is a tried-and-true, race-proven transmission that is very capable of handling the V8's horsepower. The gearing is evenly spaced to allow the engine to use all of its torque to drive the rear wheels.

So what does all that hardware get you? According to Ford, the GT500 will generate 500 horsepower at 6,000 rpm and 480 lb-ft of torque at 4,500 rpm.

Mustang Handling and Specs

Although American muscle cars are usually known for flat-out, straight-line speed, the history of the Mustang shows that a car made in Detroit can be successful on the technically challenging road courses in the United States and Europe. The original Shelby Mustangs were very nimble on twisting tracks. The modern GT500 is no different.

An independent MacPherson strut suspension with reverse-L lower control arms anchors the front end, while a three-link solid axle shores up the rear, aided by a track bar to prevent lateral motion. Both front and rear stabilizer bars help minimize body roll. Brembo brakes add to the handling performance, with 14-inch, four-piston discs in front and 11.8-inch, single-piston discs in the rear, linked to the car's ABS system. The 18-inch aluminum wheels hold P255/45ZR and P285/40ZR high-performance tires, and a power-assisted, rack-and-pinion steering system rounds out the handling package.

A New Old Design

Instead of the standard Mustang horse logo, the GT500 features silver Cobra badges. Still, the GT500 is instantly recognizable as a Mustang, with many elements of the design meant to invoke the original GT500, last produced in 1970, as well as other Shelby Mustangs of the 1960s.

The styling was originally tested on the Mustang GT coupe and refined on the Mustang GT-R before reaching the GT500 stage of design. In the Mustang heritage, vents in the hood draw heat away from the engine compartment, and the rear spoiler is reminiscent of earlier Shelby designs.

Virtually every surface of the interior is covered in black leather, with "SVT red" door panels and seat surfaces. "Leather has long been a performance fashion accessory for enthusiasts, from jackets to racing gloves, so it perfectly matches all the other driving oriented cues," said Keith Rogman, Mustang senior designer.

All the metal parts in the interior have a satin finish, rather than chrome.

The instrument panel reflects the car's breeding as a racecar: The positions of the speedometer and tachometer have been switched so that the tach is more prominent than usual, and a boost gauge allows the driver to keep constant tabs on the status of supercharger.
