“Just a few minutes behind the new Mustang’s wheel convince you that Ford was aiming high with this car. The cabin isolation, the structural stiffness, the body control, and the finish quality are huge improvements over the last model. Is it all down to the independent rear suspension? Sure, some of it is. Over cracked pavement the car doesn’t shudder or clomp as hard as it did before. And a midcorner pavement heave isn’t going to have you fighting the steering wheel as you once did, because such things are now digested without complaint by the unsprung bits.
“Ah, but what about the four’s acceleration? On the track, it lays down numbers almost identical to the last V-6 model, which was more than 100 pounds lighter than our Premium-trim automatic-transmission 2015 Mustang EcoBoost. The 60-mph mark comes in 5.2 seconds, the quarter-mile covered in 13.9 seconds at 98 mph. This is about what pre-Coyote-engine Mustang GTs once ran. So the EcoBoost is no EcoDud.” -- Car and Driver
