According to the latest rumors Ford is currently working on an even more powerful Mustang Shelby GT500. The current Shelby GT500 puts out 550 horsepower from its 5.4L V8, but new competition from the Camaro ZL1 has Ford looking for even more power. Sources claim that Ford is going to increase the power of the 2013 Shelby GT500 by boring out the 5.4L V8 to 5.8 liters. The increased size and a new supercharger could see the horsepower number climb up to 620.

The 2013 Mustang will get a refresh that is said to take it beyond its current retro styling for something more modern.
