For 2011 the Ford Mustang GT500 seemingly went through a minor change. The cast-iron block was replaced by an aluminum one. One derived from the mid-engine exotic Ford GT. It save 100 lb. off the front end of the otherwise nose heavy, but powerful (output to 550 bhp and 510 lb.-ft. of torque) muscle car.
We were told at the unveiling at the Chicago show that a new SVT Performance Package would upgrade the wheels, tires and suspension. Doesn't sound like a huge change, but apparently it is. The new car just turned a 2:58.5 lap at Virginia International Raceway. In the press release sent out today by Ford they say that's NINE SECONDS quicker than the 2010 model that only ran a 3:07.4 lap. That's a significant improvement around the 4.1-mile track. I verified with Ford PR that this run of the 2010 model was done at the same time, and they confirm that it was. Patrick Hespen of Ford Communications had this to say "our guys turned a 3:07.4 the same day they ran this video. Apples to apples. They had a 2010 and this 2011 there that day for testing. The driver was Gene Martindale who'll admit to a sloppy lap. He has driven in ALMS, the Grand Am Continental series, the Mustang Challenge series, and at the Baja 1000." So if the new GT500 is this fast where does that leave the Dodge Challenger SRT8 and Camaro SS? In the dust apparently.
