Built in limited production, the 2011 Shelby GT500™ is a prize among collectible American muscle. The latest model holds true to its Shelby racing heritage, and it offers more power and performance-enhancing additions than ever before.
Jamal Hameedi, SVT chief engineer, gave us the highlights of the new GT500, which you can view in this video.
The Shelby GT500 combines power and fuel economy into one impressive package. It’s powered by an all-new, aluminum-block 5.4-liter supercharged V-8 engine, which produces 550 horsepower and 510 ft.-lb. of torque, a 10 horsepower increase versus the 2010 model. And, it will be the first modern Shelby without the gas guzzler tax, thanks to the EPA-projected 23 mpg highway and 15 mpg city it will deliver. Fuel economy gains come from the new aluminum-block engine that is 102 pounds lighter, Electric Power Assist Steering (EPAS) and aerodynamic changes to the underside of the vehicle.
The Shelby GT500 is equipped with a Tremec six-speed manual transmission, a limited-slip rear differential with 3.55:1 gear ratio or an optional 3.73:1. Stopping performance is provided by Brembo four-piston front brake calipers and 14-inch vented rotors.
New for 2011 is an SVT Performance Package for enthusiasts who want even more performance out of their Shelby GT500 for racetrack-ready driving dynamics. Complete with all-new Goodyear Eagle® F1 SuperCar G: 2 tires that SVT engineers worked directly with Goodyear to develop, the car is ready to race. The tires offer superb dry traction and precise handling with a race-inspired high-performance tread compound. The optional package also offers unique styling, lighter wheels, a higher rear-axle ratio and stiffer springs. It is available on both the convertible and coupe.
The new engine uses state-of-the-art Plasma Transferred Wire Arc (PTWA) liner coating, a process that applies a 150-micron composite coating that contains nanoparticles on the internal surfaces of engine cylinder bores, replacing cast-iron liners typically used in aluminum engine blocks. This is the first Ford application of the technology, and it offers improved overall performance and durability, along with functional benefits of reduced friction between piston rings and cylinder bores, improved heat transfer due to increased surface contact area and a weight savings of 8.5 pounds compared to a typical steel-sleeved aluminum block.
