Detroit Motor Show: Shelby Mustang GT500

Bit of a bump. Final specs are out - 500HP!


2007 FORD SHELBY GT500 OFFICIALLY RATED AT 500 HORSEPOWER
# 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.

They originally put it at 450hp, and now it's gotten a 50hp bump.

So quit complaining. :p
 
"It borrows the four-valve cylinder heads, piston rings and bearings, from the Ford GT engine."

Too bad it couldn't borrow the GT's aluminum block and save a couple hundred pounds! :thumbsdown:

The aluminum block would have added thousands and thousands of dollars to the price.

With 500HP, who really cares? Now I just want to know how much it'll cost!
 
Awesome, but with 500hp and a solid rear axle, what exactly is the GT500 supposed to compete against?

Anything it wants to. ;)


Seriously, though, the GT500 is a low-volume niche car. It doesn't really compete with anything directly (nor does it have to.) I mean, it's got 500HP and it will probably cost around the same as an S2000. I know which one I'd have.
 
The S2000, of course.
With a bodykit and a HUGE rear wing...
 
I think the biggest reason to buy a GT500 is SVT.

SVT is dead. This car is the last product they made before being dissolved by Ford. Which means all their future performance cars will be designed and built by the same people that build the SUVs and Minivans. This car is going to holds it value forever and only increase price. It's one of those super rare automobiles that will actually be a good investment.
 
I?m with you. It has huge potencial to be a classic
 
i have a strange feeling that if you were to get that car. youd get clarckson syndrome and end up stopping every 200 miles to buy gas. i wouldnt mind that. but soon a gallon of gas will be $5 :( but what a car!
