'SVT keeps the Shelby GT500 on the cutting edge of technology and takes muscle car performance to new heights,' said Jamal Hameedi, SVT chief engineer. 'We encapsulated every aspect of performance in this car – whether it's 0-60, top speed, racetrack or quarter-mile times. Beyond that, the daily driver also will find this car perfectly fits his or her needs.'
The 5.8-liter aluminum-block V8 engine produces 662 horsepower and 631 lb.-ft. of torque, making it the most powerful production V8 in the world. The 3,850-pound car also stays exempt from the gas-guzzler tax.
Nearly every part of the powertrain has been optimized for producing the massive horsepower, including the supercharger, cross-drilled block and heads, camshaft profiles, carbon fiber driveshaft and upgraded clutch, transmission and axle.
A TVS series 2300 supercharger flowing air through the engine is key to helping produce the GT500's 662 horsepower. The 2.3-liter supercharger is a unique design to the 5.8-liter engine.
The entire cooling system is up to the task of dissipating the heat produced by the 5.8-liter engine. It now includes a larger cooling fan, fan shroud wîth high-speed pressure-relief doors, a more efficient charge air cooler, a higher-flow intercooler pump, and an intercooler heat exchanger wîth volume increased 36 percent compared to earlier GT500 engines.
Gearing The gearing on the 2014 Shelby GT500 has been optimized to manage the torque and use more of the power in a way that makes it more driver-friendly. Engineers considered more than 35 gearing combinations, finally deciding on one that balances torque being transmitted all the way through the wheels and grip to the ground.
A key piece of the driveline, the six-speed manual transmission, offers upgraded gears, bearings and housing so it can properly manage the torque. The final drive ratio is now 3.31:1 for optimized overall vehicle gearing to complement the massive torque. The clutch has the torque and rpm capacity to match the massive output of the engine, and uses a dual-disc design.
'It might just seem like we're putting a bigger engine into the car. But it's been a balanced approach through and through,' said Kerry Baldori, Ford SVT global performance vehicles chief engineer. 'We've completely redone the car to be even more sophisticated in terms of handling and control than earlier models.'
Other keys for improved traction management include:
•Torsen

limited-slip differential: When customers order the optional Performance Package, they get a Torsen limited-slip differential that helps the rear suspension deliver maximum torque and traction better and longer under track conditions
•Launch control: The launch control system lets drivers set the desired launch rpm depending on tire temperature, street surface or other conditions. Únique to SVT's launch control is its integration wîth both the engine control and traction control
•Brembo braking system: A Brembo brake system offers drivers enhanced stopping power to help keep their car under control, both on the road and the track. Six-piston calipers in front along wîth larger front and rear rotors help improve resistance to brake fade. New brake pads that are more aggressive also help the car achieve high deceleration and further robustness for more driver confidence.
