Ford are touting the 2012-2013 Shelby GT-500 as the “most powerful series production V8 in the world.”

The ultimate Ford Mustang – Shelby GT500 – raises the bar high on performance by delivering 662 horsepower and a track-tested top speed of more than 200 mph. The 5.8-liter supercharged V8 aluminum-block engine produces 650 horsepower and 631 lb.-ft. of torque, making it the most powerful production V8 in the world.

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.

SVT chief engineer Jamal Hameedi, “Our goal is to create outstanding all-around performance cars, not just stoplight-to-stoplight sprinters. 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.”
