Ford Mustang Shelby GT500 662 hp!

You might recall that a few scant minutes ago, Ford had declined to confirm that the 2013 Mustang Shelby GT500 was certified by the SAE to crank out no less than 662 hp and 630 lb-ft of torque. In light of the leak, Ford has reversed its decision and 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 Ford Motor Co., the 2013 GT500 makes 662 hp and 631 lb-ft. Which is one louder, right? What\'s more, there is 395 lb-ft of torque available at 1,000 rpm, and, according to Ford, more than 90 percent of peak torque is available from 2,200 rpm to 5,800 rpm. Tires, thy name is haze. Perhaps the most startling factoid, though, is that at 15 city/24 highway mpg and 18 mpg combined, the stonkingest factory Mustang that ever was actually avoids the gas-guzzler tax.
