Now for what you've been waiting for: the new 2015 Mustang GT accelerates from 0 to 60 mph in 4.4 seconds, and gallops through the quarter mile in 12.8 seconds at 112.2 mph. That's just a tick slower than the last performance-pack-equipped 2013 Mustang GT we tested. The old S197 model ties the 2015 model in a race to 60 mph and completes the quarter mile a tick faster at 12.7 seconds, with a 111.7 mph trap speed. Big six-piston Brembo front brakes help the new Mustang come to a stop from 60 mph in 107 feet, a yard shorter than the outgoing model.
