2015 Ford Mustang GT: Performance Testing Redux

by Reese Counts, Vehicle Testing Assistant on December 11, 2015

2015 Ford Mustang GT

The Mustang is one of the most commonly modified vehicles in history. We decided to join the party with our long-term 2015 Ford Mustang GT by making it a lot louder, a little lower and its shifts slightly shorter. Finally, we wrapped the Mustang in fresh rubber and traced down the source of a mysterious noise.

As with all our long-term test vehicles, we tested the Mustang shortly after it was purchased. With all these new parts installed, we put Senior Editor Josh Jacquot behind the wheel for another go. Like many modifications, the numbers alone don't tell the full story.

RPM @ 70: x 2,100

Comments
Acceleration:
"Best run using launch control at 3,400 rpm. Shifter allows rapid shifts, but feels bad for tranny. No new news here. Launch control removes most of the technique from the launch, leaving only the trial-and-error of picking launch rpm. I had one run several tenths quicker but forgot to hit the log button. Couldn't duplicate after many attempts.                                                                       
Braking:
Extremely solid pedal has almost no compliance, which hurts feel. Matters little in full ABS stops, however. Consistent. No pedal fade.    

Handling
Slalom: Feels truly drivable through slalom. Predictable, intuitive, well-controlled. Better than before. Track mode allows a reasonable amount of limits-exploring. Even small slides are permitted and controllable. Possibly this is the only noticeable difference versus the last test with wheels in the wrong place.

Skid pad: No improvement over last test. Handling balance still very different clockwise vs. counterclockwise with counterclockwise balance allowing far more adjustment at the limit. Clockwise, only wants to understeer.
