Muscle One-upmanship Continues, Next Mustang Shelby GT500 To Get 600 Ponies

Though mile-per-gallon competitions have provided a contemporary side show for the muscle car wars, in the end, it's all about pure, unadulterated power. At the 2011 Chicago Auto Show, Chevy raised the bar with the all-new 2012 ZL1, a 550-hp beast of a Camaro. Now, rumors indicate that Ford isn't going to sit idly and let Chevy steal its thunder. Car and Driver reports that the next Mustang Shelby GT500 may just leap well over 600 hp.

Car and Driver's report points to a horsepower bump that will put the 2013 Shelby GT500 over 600 horsepower and possibly as high as 620. To achieve the upgrade, the displacement on the current 5.4-liter V8 engine will be bumped up to 5.8 liters, and a more efficient TVS supercharger will replace the Eaton M112. Interestingly enough, that's the same charger that Chevy uses to pump 550 horses out of the Camaro ZL1's 6.2-liter LSA engine. It also appears in such notable GM efforts as the Cadillac CTS-V and the Corvette ZR1.

The current top 'Stang, the 2012 Mustang Shelby GT500, puts out 550 horses. It hits 60 mph in 4.1 seconds and a quarter mile in 12.4 seconds. Car and Driver predicts that the upgraded muscle icon will cut that quarter mile time down to 12 seconds flat and will be capable of upwards of 190 mph, if not cut off by an electronic limitation.

The 2012 GT500 is priced at $48,645, so the 2013 model will undoubtedly jump over the half-century mark. Car and Driver expects it to leap as high as $60K.

The Camaro ZL1 will hit the market later this year, and will likely get competition from the 2013 GT500 about a year after that. Chevy is still testing the prototype version of the ZL1 and we hope to have some finalized specs in the coming months.
