The 2013 Ford Mustang Shelby GT500 is about to go where no Mustang has gone before, with a complete package for everyday drivers and track-day enthusiasts alike, 662 horsepower and top track speeds of more than 200 mph.
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. The entire cooling system has been significantly updated on the new 5.8-liter engine. It now includes a high-capacity cooling fan, fan shroud with high-speed pressure-relief doors, a more efficient charge air cooler, a higher-flow intercooler pump and an intercooler heat exchanger whose volume is increased 36 percent. These components harmonize to consistently dissipate heat under extreme-use conditions.
The supercharger design includes four lobes with a 160 degree twist and has a drive ratio that spins 2.64 times faster than the previous model. The inlet air volume also has been increased 33 percent. Boost has been increased from 9 to 14 psi. Other modifications for improved power include an upgraded camshaft profile, similar to the Ford GT. The cam lift for the intake and exhaust has been increased for improved airflow. Additionally, the redline is held at 6,250 rpm continuously, but allows for an over rev to 7,000 rpm for eight seconds to extend the time to shift so that acceleration is higher and 0-60 mph and quarter-mile times can be faster.
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.A new front splitter and black-painted upper and lower grille inserts that expose the radiator drive the functional style changes to the Shelby GT500. The exposed radiator helps funnel air and cools the internals of the vehicle systems. The larger splitter helps create downforce when the car hits top speeds.
