Design enhancements for 2013 include all-new signature lighting with two LED bars that command attention in the front and rear. The rocker panels running along the car are now body-color, adding a more premium look. Additionally, the rear end has a new high-gloss black panel between the taillamps and a diffuser that surrounds a new quad-tip exhaust.
The 2013 Shelby GT500 offers two new sets of forged-aluminum wheels, including a unique wheel for cars with the optional packages. The 19-inch front and 20-inch rear wheels are coupled with Goodyear Eagle® F1 SuperCar G: 2 tires on all configurations.
The new Shelby GT500 driving dynamics have been overhauled, now working in concert with Goodyear tires. New Brembo™ brakes with six-piston calipers in front and the new wheels also required unique suspension tuning to ensure everything works harmoniously.
The 5.8-liter V8 aluminum-block engine produces 662 horsepower and 631 lb.-ft. of torque, making it the highest-horsepower engine ever produced in North America. Nearly every part of the powertrain has been optimized for producing the additional horsepower, including a new supercharger, new cross-drilled block and heads, an all-forged engine rotating assembly, updated camshaft profiles, upgraded head gaskets, a new carbon fiber driveshaft and upgraded clutch, transmission and axle.
A larger and more efficient supercharger helping flow more air through the engine is key to producing the 662 horsepower. The new Twin Vortices Series 2300 blower creates 2.3 liters of displacement and is a unique design to the 5.8-liter engine.
