Ford planning 620-hp Shelby GT500?

Not wanting to let the competition get ahead, Ford is planning an even more powerful Shelby GT500 for 2013.

With the launch of the 550-horsepower Chevrolet Camaro ZL1 still fresh on people's minds, Ford is reportedly going back to the drawing board and beefing up its Shelby GT500 for the 2013 model year.

The Shelby GT500 already boasts an impressive 550 horsepower, but Ford isn't interested in just matching the ZL1's output. As a result, a new engine is said to be on tap for 2013, generating in excess of 600 horsepower.

According to Car and Driver, Ford will increase the size of the GT500's motor from 5.4L to 5.8L for the 2013 model year. That displacement increase will also be accompanied by a supercharger swap - with Ford ditching the current Eaton unit for the same TVS unit found under the hood of the ZL1 - resulting in a horsepower rating as high as 620.

Given that added power, the GT500's 0-60 run could dip into the 3 second range, with a 12 second flat Ã'¼ mile sprint. Flat out the GT500 should be traveling in excess of 190mph.

A few body tweaks are also expected for 2013, but Ford still has plenty of time to work out those design changes. The revised Shelby GT500 is expected to hit the market until late 2013.
