The owner of a 2011 Mustang V6 found out the hard way why Ford put a 112 mph speed limiter on the engine. After removing the speed limiter and driving to a speed of 135 mph the Mustang V6’s driveshaft abruptly failed creating chaos for the driver. Not only was the driveshaft destroyed but the floorpan was punctured, the transmission shifter broke, the parking brake broke and a few interior parts were damaged. Check out the video below.
