2007 Shelby GT500: 500HP Snake Hunter
Ford sent a fairly emphatic message to GM and Chrysler on Monday as it announced that the 2007 Ford Shelby GT500 officially produces 500 horsepower and 480 lb-ft of torque. Those numbers put the new Shelby on the same playing field as the Corvette Z06 and Dodge Viper, and set the stage for the inevitable King of the Hill comparison tests from all the big magazines later this summer.
Following Mark Fields' very public vote of confidence for SVT at April's NY Auto Show, the 500-horsepower revelation gives the factory skunkworks its second big headline in as many months. SVT honcho Hau Thai-Tang summed things up pretty succintly:
“With 500 hp and the Shelby name, this car is an instant legend. This is the most powerful, most capable Mustang ever."
The GT500's "legend" status was never really in question. The importance of the car became abundantly clear when the rights to serial number 001 sold for $600,000 at Barrett-Jackson in Scottsdale. 500HP is a magic number, though - one that is commonly attached to vehicles that are far more exotic and cost several times as much to buy.
The SVT Mustangs have gotten progressively better through the years, and the new Shelby GT500 represents the pinnacle of the SVT division's prowess with Ford's ponycar. Yes, Carroll Shelby's name is on the outside, but beneath the surface, where all the magic is happening, it's SVT's baby.
Hau Thai-Tang's verbal swagger is understandable. After all, his SVT crew has produced the most desirable American car to hit the market in decades.
Here's the full release from Ford:

- Ford Shelby GT500 officially rated at 500 horsepower, 25 horsepower higher than preliminary estimates
- The Shelby GT500 will go on sale this summer with more horsepower than any previous factory-built Mustang
DEARBORN, Mich., May 2 - The most powerful factory-built Mustang ever just got even more potent. Final certification testing of the Shelby GT500’s 5.4-liter supercharged V-8 shows it will produce 500 horsepower and 480 lb.-ft. of torque – 25 more horsepower than preliminary estimates.
“With 500 hp and the Shelby name, this car is an instant legend," said Hau Thai-Tang, director, Advanced Product Creation & SVT programs. "This is the most powerful, most capable Mustang ever."
The Ford Shelby GT500's supercharged 5.4-liter, 32-valve V-8 is a result of Ford's experience in developing the modular V-8 and V-10 engine series. The engine is force-fed air via a "Roots-type" supercharger providing 9 pounds per square inch of boost. It borrows the four-valve cylinder heads, piston rings and bearings, from the Ford GT engine.
The 500 hp rating was obtained using the Society of Automotive Engineer's latest standard and was witnessed by an objective third party. The Shelby GT500's 5.4-liter supercharged V-8 will be built at Ford's Romeo Engine Plant in Romeo, Mich. Pricing will be announced closer to launch.
The right to purchase the first 2007 Ford Shelby GT500 was auctioned for $600,000, with the proceeds benefiting the Carroll Shelby Children's Foundation. The 2007 Ford Shelby GT500 goes on sale this summer.
