Specs: 332 Horsepower / 350 Pound-Feet
The most powerful four-cylinder Mustang is the EcoBoost High Performance pack. Though it has the same displacement as its base EcoBoost siblings, this model uses a retuned version of the Ford Focus RS engine, which produces a heartier 332 horsepower and 350 pound-feet. That means the Mustang can hit 60 miles per hour in just 4.5 seconds. The High Performance package is a $4,995 option on any EcoBoost model, coupe or convertible, and if you want the optional handling package on top of that (which we recommend), it's another $3,995. But you can get an EcoBoost HPP for as little as $31,665 (not including destination fees).
