More horsepower, more refinement, more functionality
The combination of added horsepower, refinement and functionality makes the 2010 Shelby GT500 a unique high-performance car. The 2010 Shelby GT500 delivers more horsepower and more torque than the outgoing model, thanks in part to advancements pioneered on the GT500KR.

The 2010 Shelby GT500 is powered by a supercharged and intercooled 5.4-liter dual overhead cam V-8 engine expected to produce 540 horsepower and 510 foot-pounds of torque. The redline is 6,250 rpm. The car’s aluminum power dome hood not only adds to the Shelby’s appearance, it helps cool the engine through a hood extractor.

The Shelby’s open-element air induction system features a conical air filter instead of a flat-panel closed system to reduce air restriction. This approach allows more air to be pumped through the engine, producing more power and increasing the engine’s efficiency.

A cold-air intake feeds the coolest air possible directly into the air box, helping further increase horsepower. The intake necessitated moving the Cobra snake badge to the other side of the grille to enable maximum airflow.

The twin-disc clutch on the six-speed manual transmission has been significantly upgraded, improving drivability and NVH. The discs on the 2010 Shelby GT500 are larger – 250 mm in diameter compared with 215 mm in diameter on the outgoing model – and made of copper and fiberglass to make them more robust.

A unique component of the twin-disc system is the control of the intermediate disc. Rather than floating, it instead has six straps that control the engagement of the clutch, improving drivability.

The 2010 Shelby GT500 offers customers improved straight-line acceleration, plus fuel savings when cruising on the highway in the top gears. Gears 1-4 remain the same, but fifth gear changes from .80 to .74 while sixth gear goes from .63 to .50, meaning that the 2010 Shelby GT500 will turn lower engine RPMs in those gears and deliver improved fuel efficiency. The new final drive ratio, from 3.31 to 3.55, enables the improved acceleration in lower gears while complementing the revised fifth and sixth gear ratios.

The Shelby’s distinct sounds will be apparent as always, though with new refinements, thanks to the work of the Noise, Vibration and Harshness (NVH) team. A patented resonator placed between the air filter and engine throttle body helps keep unwanted noise in check.

“You still hear the supercharger but not so that it’s intrusive,” said Kerry Baldori, chief functional engineer for SVT. “It’s the same with the exhaust. You want people to know you’re driving something special, but you don’t want an exhaust note that overpowers the whole interior.

“We spent a lot of time getting the right sound quality out of the exhaust so you get that nice, crisp Shelby sound outside and a pleasant sound inside the cabin. It’s a nice balance; one isn’t overpowering the other.”
