Rumormill: 2013 Shelby GT500 to boast over 600 horsepower

The golden age of horsepower ended a long time ago in a galaxy far, far away, right? Well, no. In reality, it seems that every new model year brings more and more ponies from the likes of the reborn Chevrolet Camaro and Dodge Challenger along with the stalwart Ford Mustang.

According to the internet rumormill, that pattern isn't going to change any time soon. Car and Driver reports that the 2013 Ford Mustang Shelby GT500 will boast as much as 620 horsepower. Naturally, the powerplant providing all those ponies will be a supercharged V8, in this case bored out to displace 5.8 liters instead of the 5.4 we've been seeing for the last several years.

Car and Driver's math tells us, assuming the power and weight estimates are in the ballpark, to expect a scorching 12.0-second quarter mile time from the 2013 GT500, a top speed that could be as high as 190 miles per hour and a sticker price of roughly $60,000.

For what it's worth, Chevrolet is estimating that the supercharged and intercooled 6.2-liter LSA V8 engine that will power its Camaro ZL1 – the top run (so far) of Chevy's muscle car lineup – will put out around 550 horsepower and 550 pound-feet of torque. Naturally, that's all subject to change...
