The Web has been ablaze with speculation over how the 2013 Ford Mustang Shelby GT500 will flex its muscle: twin-turbo or supercharger? Through the haze, emerges an answer: A supercharger, a Motor Authority source suggests.
Additionally it appears that the 2014 debut will thunder out of the gates with more than the current 550 horsepower. Exact figures aren’t yet available but nearly 600 horsepower is a possibility. This could be Ford’s way of preparing for the Chevrolet Camaro ZL1. The ZL1 currently packs 550 horsepower, and 550 lb-ft of torque. Generous muscle, but it appears the competition is beefing up.
While the GT500′s engine gets a boost, the styling should remain similar to the 2012 model that’s pictured, with a major redesign planned for the 2015 models.
