New 500 Belts Out 662

Not a surprise with Ford anymore, but the 2013 GT500 was a little
unrated. Read on...

----
You might recall that a few scant minutes ago, Ford had declined to
confirm that the 2013 Shelby GT500 was certified by the SAE to crank
out no less than 662 horsepower and 630 lb-ft of torque.

In light of the leak, they've reversed their decision and have decided
to officially confirm the number. The rumors, apparently, were off by
one foot-pound of torque. Officially, according to the Society of
Automotive Engineers and the Ford Motor Company, the 2013 GT500 makes
662 hp and 631 lb-ft. Which is one louder, innit?

What's more, there's 395 lb-ft available at 1,000 RPM, and according
to Ford, over 90% of peak torque is available from 2,200 to 5,800.
Tires, thy name is haze.

Perhaps the most startling factoid, though, is that at 15 mpg city/24
highway and 18 combined, the stonkingest factory Mustang that ever was
actually avoids the gas guzzler tax.
