Ford are touting the 2012-2013 Shelby GT-500 as the “most powerful series production V8 in the world.”
The ultimate Ford Mustang – Shelby GT500 – raises the bar high on performance by delivering 662 horsepower and a track-tested top speed of more than 200 mph. The 5.8-liter supercharged V8 aluminum-block engine produces 650 horsepower and 631 lb.-ft. of torque, making it the most powerful production V8 in the world.
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.
SVT chief engineer Jamal Hameedi, “Our goal is to create outstanding all-around performance cars, not just stoplight-to-stoplight sprinters. We’ve backed up this amazing powerplant with a more refined chassis tuning that helps keep the rubber on the pavement without punishing the driver’s spine and six-pot Brembo brakes that dissipate speed with ease stop after stop.”
The 2011 Mustang features all-new V6 and V8 engines for the mass production model, and the GT500 Ford is going to an all-aluminum version of the 5.4-liter supercharged V8 that was in the 2010 GT500. This new engine is good for a 102 pound weight decrease, as well as 10 horsepower surge over the previous model – putting total output at 550 horsepower and 510 lb-ft. of torque.
“Cutting weight to improve performance is a tradition among hot rodders,” said Carroll Shelby in a statement released to the media. “It might not be as sexy as adding more horsepower or bigger brakes, but shaving pounds off of a car is the single smartest move you can make.”
Ford also points out that this new Shelby Mustang is uses an engine with roots in the now discontinued Ford GT supercar – but with improved block structure through the use of a unique bulkhead chilled process and six-bolt billet main bearing caps. Ford says that the 2011 Shelby GT500 engine will exceed Ford GT performance due to its superior supercharger technology.
With increased power comes…increased fuel efficiency?
Bucking the trend of range-topping muscle cars receiving a gas guzzler’s tax, Ford says the 2011 Shelby GT500 will be the first modern Shelby without a gas guzzler tax, thanks to the EPA-projected 15 mpg city, and 23 mpg highway ratings. Ford’s engine changes also result in 80 percent torque being available between 1,750 and 6,250 rpm, along with a larger two-row intercooler that delivers 40 percent more cooling capacity.
Ford achieved the increase in fuel economy through a combination of weight savings from the use of an all-aluminum engine block, improved body and undercarriage aerodynamics and the addition of Electric Power Assisted Steering.
New performance features for 2011
Likely the most significant option change for the GT500 is the SVT Performance Package – giving the GT500 a track-ready performance pack from the factory. This package includes specially developed Goodyear Eagle F1 SuperCar G: 2 tires, a higher rear axle ratio, stiffer springs, lighter wheels and cosmetic changes for both the coupe and convertible. Ford attributes a 3.0-second lap time savings over the 2010 coupe on the 2.3-mile test track.
On the 45th anniversary of the original Shelby GT350, Carroll Shelby is revealing the latest version of the hopped-up Ford Mustang tonight at the opening gala of the Barrett-Jackson auction in Scottsdale, Ariz.
Shelby added a new rear look to create the GT350 from a 2011 Mustang GTCAPTIONBy Shelby AmericanThe new GT350 is a supercharged 2011 Ford Mustang GT that will go on sale in the spring with a combined pricetag — both for the car then Shelby American’s modifications — at more than $60,000. Shelby American says more than 100 devotees have already placed orders.
Shelby, 87, says the new GT350 has “got some of the old and some of the new:”
The supercharging should push the horsepower of Ford’s new 5-liter engine past 500, up from 412 of stock, and it has the look of the original — white with blue stripes. He says he loves the look of the front and rear ends, as well as the braking and handling.
To his regret, he can’t behind the wheel and put the car through hot paces anymore. “I’m three-quarters blind now and I don’t drive fast anymore,” said the automotive legend. Ford will continue to make its licensed Shelby GT500 with the 5.4-liter V-8, but the Shelby GT350 should be more nimble and plenty fast on the track.
