Weight is bad for performance—this is why Rick Ross didn't make the Olympic figure skating team—and that holds true for cars as well as people. Every pound added is another pound that has to be pushed into movement or redirected, and both of these things take precious, precious Newtons of force.
That's we we're sad to report that Mustangs Daily published the following from tuner Steeda: "Our work is cut out for us because unbeknown to most Mustang aficionados (and not "officially" confirmed by Ford for obvious reasons), the 2015 Mustang ended up gaining 200-300 pounds in this remake – and with weight being the "enemy of performance", there are plenty of challenges needed to ensure that the 2015 iteration of America's favorite Pony Car isn't left at the starting line spinning its wheels against the competition."
Ouch, the Mustang's biggest advantage over the Camaro was that it was 300 pounds lighter. All that new tech and the IRS will have its work cut out for it just keeping pace.
