Ford Shelby Mustang GT � SAE-Certified at 500 HP

WARRENDALE, Pa., Jan. 17, 2007 - Ford’s famous “pony” officially has 500 horses.

That’s one way of saying that the Ford Shelby Mustang GT500 engine officially has been tested and certified at 500 horsepower through SAE International's J1349 Certified Power Standard.

The engine is the second Ford-badged engine to be certified through the standard – the other is the 2007 Ford Edge engine.

Engine certification is based on a series of self-certification tests conducted by the manufacturer that are witnessed and verified by an SAE-qualified observer. The procedure for certification is outlined in SAE's standard J2723; the actual horsepower testing procedure is described in J1349. Engine manufacturers are free to cite power and torque figures derived from testing conducted outside the scope of the SAE standards, but in those cases they may not claim those figures are "SAE J1349 Certified Power."

More than 40 engines have been certified under SAE J1349, including engines from Ford, General Motors and DaimlerChrysler.  In addition to the Ford Shelby GT500, two other engines have been certified at 500 or more horsepower – the 2006 Chevrolet Corvette Z06 and the 2006 Dodge Viper.

The SAE Detroit Section meeting on January 30 will feature the Ford Shelby Mustang GT500. For more information on the meeting, visit
