Fans of ultra-performance cars are rejoicing at the news announced at the 2011 LA Auto Show. The ultimate Ford Mustang – Shelby GT500 – raises the bar high on performance with the introduction of the new 2013 model delivering 650 horsepower and a top speed of more than 200 mph. Jamal Hameedi, SVT Chief Engineer, gave us more details on the car during a video interview, seen above.
The 5.8-liter V8 aluminum-block engine produces 650 horsepower and 600 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.
A larger, more-efficient supercharger flowing more air through the engine is key to helping produce the massive 650 horsepower. The new TVS series 2300 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 larger 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 with volume increased 36 percent.
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.
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. Every gear besides fourth was optimized for competing performance metrics. The clutch has increased torque and rpm capacity and uses a dual-disc design.
Other keys for improved traction management include:
Significant aerodynamic work was done on the new Shelby GT500 to ensure the car has proper downforce for optimum performance at all speeds. Engineers were able to determine how to harness the air that was moving around and through the car to improve the cooling system, maximize downforce and minimize drag.
The front fascia and splitters were modified to handle the extreme loads at 200 mph, resulting in a car that tracks more securely and feels more planted to the road at higher speeds. It offers 33 percent more effective aero loading at 160 mph compared to the 2011 model.
Enthusiasts can upgrade their Performance Package with an additional Track Package for all-out performance. The option comes with an external engine oil cooler, rear differential cooler and transmission cooler for further durability. The coolers play an essential role in preventing crucial components from overheating under high-speed conditions.
