DETROIT — The Detroit muscle car horsepower race escalated last week when Ford Motor Co. announced that the 2013 Shelby GT500 Mustang will have a 650-horsepower V-8 engine.
The company unveiled the GT500 and a freshened version of the regular Mustang at the Los Angeles Auto Show. Ford says the Shelby version will have the most powerful production V-8 engine in the world, with a top speed of more than 200 mph.
The 5.8-liter engine is mated with a six-speed automatic transmission.
Ford wouldn’t release the gasoline mileage but said it would be good enough to avoid the U.S. tax on gas guzzlers.
The GT500 would beat the most powerful model put out by rival General Motors Co. by 12 horsepower. The Chevrolet Corvette ZR-1 is rated at 638 horsepower.
Ford also unveiled the freshened 2013 Mustang, which comes with more aggressive styling and new LED lighting to give it a high-tech look, the company said.
