2013 Ford Shelby GT500 Rated at 662 Horsepower
Ford has outdone itself this time. Initially promising 650 horses, the 2013 Ford Shelby GT500 has been officially SAE-certified at 662 horsepower and 631 lb-ft of torque. That makes it the most powerful series production V8 in the world.
There's more. Ford says the Shelby GT500 is also the most fuel-efficient vehicle in its segment with an EPA-estimated 15 mpg city, 24 mpg highway and 18 mpg combined with no gas guzzler tax.
According to Ford, nearly every part of the powertrain has been optimized for producing the additional horsepower, including a new supercharger, new cross-drilled block and heads, updated camshaft profiles, a new carbon fiber driveshaft and upgraded clutch, transmission and axle.
“Our goal is to create outstanding all-around performance cars, not just stoplight-to-stoplight sprinters,” said Jamal Hameedi, SVT chief engineer. “We’ve backed up this amazing powerplant with a more refined chassis tuning that helps keep the rubber on the pavement without punishing the driver’s spine and six-pot Brembo brakes that dissipate speed with ease stop after stop.”
The 2013 Ford Shelby GT500 will be built at AutoAlliance International Plant in Flat Rock, Mich.
