We all knew the 2013 Ford Shelby GT500 was a special car when it was introduced earlier this year at the Detroit Auto Show with an estimated 650 horsepower, but now Ford has an even bigger advantage over rival muscle cars with an official rating off 662 hp announced today. In the grand scheme of things, this engine solidifies itself even further as the most powerful production V-8 in the world, but we're pretty sure that Mustang fans will just be happy to blow the doors off any Camaro - and probably even Corvette for that matter - straight from the factory. On top of everything else, the price hasn't jumped as much as the power output has with the new Shelby GT500 having a starting MSRP of $54,200 for the coupe and $59,200 for the convertible when they go on sale this summer.
The 5.8-liter supercharged V-8 is officially rated at 662 horsepower that peaks at around 6,500 rpm and 631 lb-ft of torque - 90 percent of which is available between 2,200 rpm and 5,800 rpm. This is a remarkable power increase over the 2012 Ford Shelby GT500 produces just 550 horsepower and 510 lb-ft of torque. Even with all this added power, the 2013 Shelby still manages to include a little fuel efficiency. Compared to last year's GT500, the 2013 model squeezes out an extra 1 mile per gallon in both city and highway driving up to 15 mpg city and 24 mpg highway, and it even beats out its main rival, the new Chevrolet Camaro ZL1, by 1 mpg in the city and 5 mpg on the highway. Chances are that none of these fuel numbers will matter though since hit GT500's 200+ mile per hour speed is far from efficient driving.
Assembled right alongside standard Mustang models in Flat Rock, Mich., the 2013 Ford Shelby GT500 has been tuned so it can handle the higher loads of this record-setting horsepower including tougher powertrain components, optimized aerodynamics and even unique option packages. To be able to handle the 662 horsepower, most of the powertrain has been beefed up with items such as the carbon fiber driveshaft and upgraded gears and clutch in the six-speed manual gearbox all the way to where the rubber meets the road with high-performance Goodyear Eagle F1 SuperCar G: 2 tires. To ensure the new Shelby could handle 200-mph speeds, Ford and SVT worked on the aerodynamics of the car making it 33 percent more effective at 160 mph which helps to keep the car planted at high speeds. Those looking to track thier GT500, there is an optional $3,495 Performance Package that includes a Torsen rear differential and Bilstein electronic adjustable damping for optimal handling.
"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," said Jamal Hameedi, SVT chief engineer. "On top of that platform they added advanced driver-adjustable electronic assist features including launch control, Bilstein adjustable damping, AdvanceTrac stability control and electric power-assisted steering."
