kurtporrine: Ford Mustang Shelby GT500

Chevrolet’s release of the all new Camaro ZL1 at the 2011 Chicago Auto Show allowed them to reignite the muscle car wars that have been burning up the automotive websites for a good and long time. But before Chevrolet can shout out "Checkmate," Ford has answered the ZL1 with an update car of their own: the 2013 Shelby GT500. Recent spy shots have revealed that the company is already testing the 2013MY GT500 and it will be more powerful than ever.

The Camaro ZL1’s LSA 6.2L supercharged V-8 engine producing an estimated 550 HP and 550 lb.-ft. of torque is nothing to shake a stick at, but Ford has one-upped them once again. The Eaton M112 supercharger that is being housed in the current GT500’s V8 engine will be replaced with the more-efficient and quieter TVS unit. The V8 engine found in the 2013 model will also get modified and bumped up to 5.8L, all while producing up to 650HP and making it the most powerful, factory made Mustang ever! The game continues...Your move Chevrolet.

UPDATE 03/16/2012: Ford has announced prices for the new 2013 Shelby GT500. The base price is $54,200, but if you want to add the SVT Performance Package, it jumps up by another $3,495. This package includes: Torsen limited-slip differential, 19" forged-aluminum front wheels or 20" forged-aluminum rear wheels, Bilstein adjustable dampers, unique rear springs, a unique instrument cluster, and an SVT gear shift knob. A glass roof will add yet another $1,995, while an electronic package adds another $2,340.

UPDATE 05/08/2012: Ford has unveiled a pretty cool commercial for the Shelby GT500. The idea behind the commercial is pretty simple: Everyone has an Inner Mustang. Unleash yours! Of course, you’ll have to wait until Summer 2012 when the Mustang goes on sale!
