Hot New Shelby Mustang to return
The most powerful factory-built Ford Mustang in history takes to the street next year, following a unique collaboration between performance car legend Carroll Shelby and the Ford Special Vehicle Team (SVT).
Ford took the wraps off the 450-plus-horsepower Ford Shelby Cobra GT500 show car at the New York International Auto Show March 23. Designed in the unmistakable image of Shelby Mustangs of the 1960s, the Shelby Cobra GT500 melds SVT's modern engineering with the big-block performance that made the original GT500 the king of the road.
"The all-new 2005 Ford Mustang is one of the hottest cars in many years," says Phil Martens, Ford group vice president, Product Creation. "Its chassis was engineered from the beginning to be the basis of a high-performance, world-class sports car from SVT, and the Shelby Cobra GT500 is it."
Carroll Shelby lends his support to SVT, adapting his earlier role as a senior advisor on the "Dream Team" that was assembled to develop and build the 2005 Ford GT. "I've worked with the SVT guys for several years now, and I know they have the guts, the talent and the passion to deliver the best performance Mustangs ever," says Shelby.
A production version of the GT500 will go on sale in 2006, continuing the high-performance lineage of the SVT Mustang Cobra model line. It will be followed by a steady stream of performance products developed by SVT, including Ford Sport Trac Adrenalin, the industry's first performance sport-utility truck, in 2007.
Shelby Cobra GT500 delivers over 450-plus horsepower
Just as the original Shelby GT500 was the "step up" to big-block power from the GT350, the new Ford Shelby Cobra GT500 steps up to Ford's 5.4-liter "MOD" V-8. The result? The GT500 is the most powerful factory Mustang ever. Its supercharged 5.4-liter, 32-valve V-8 evolves from SVT's experience with supercharging the "MOD" engine to deliver more than 450 horsepower and 450 foot pounds of torque.
The cast-iron-block, four-valve engine is force-fed an air-and-fuel mixture via a screw-type supercharger at 8.5 pounds per square inch of boost. Aluminum cylinder heads, piston rings and bearings sourced from the Ford GT program bring a high level of proven durability to the drivetrain, while upgraded cooling components promise longevity. "Powered by SVT" camshaft covers are the finishing touch to the engine.
The engine has been further tuned from its first application in a Mustang, the 2000 SVT Mustang Cobra R, a limited edition model of 300 units.
Helping to put the power of the GT500's supercharged V-8 to the pavement is a T-56 six-speed manual gearbox. The evenly spaced gears mean less stirring is needed to find the "sweet spot" in keeping the revs "on cam" for power to pass, while at the same time making the most of the engine's broad torque curve. The heavy-duty transmission has proven itself a willing companion to V-8 power in Mustangs in both road and track environments, including the 2000 SVT Mustang Cobra R, 2004 SVT Mustang Cobra and the new race-winning Ford Racing Mustang FR500C.
Great power requires great control
The great Shelby Mustangs of the 1960s were anything but one-trick ponies. They earned their stripes on twisty roads and race tracks across America and Europe. The Shelby Cobra GT500 show car continues that legacy of all-around performance.
The GT500 starts with the solid 2005 Mustang underpinnings. Using real-world experience gained during more than 12 years of building great-handling SVT Mustang Cobras, SVT engineers retune and upgrade key chassis components. Improvements such as revised shocks, spring rates and upgraded stabilizer bars help the GT500 stop and turn with the same authority as it goes.
The GT500 features a MacPherson strut independent front suspension with "Reverse L" lower control arms, and a solid-axle, three-link rear suspension with coil springs and a Panhard rod for precise control of the rear axle.
To match this power and handling ability, SVT fitted some of the biggest brakes in the business to the GT500. Fourteen-inch cross-drilled Brembo rotors up front and 13-inch discs in the rear continue SVT's legacy of great-braking Mustangs. Secure footing is provided by 19-inch wheels wrapped in high-performance tires.
