Born of a small cadre of Mustang engineers wondering "What if..?," this vehicle was conceived largely as an after-hours, shoestring-budget project. All-in, the EcoBoost High Performance Package only took about 10 months to come together -- an unusually short gestation period -- even for something well short of an all-new model.

This being a performance car, the first thing you'll want to know about is the power figures: The 2.3-liter turbo four provides an estimated 330 horsepower and 350 pound-feet of torque on premium gas. That's relatively close to the existing base Mustang EcoBoost's ratings of 310 hp and 350 pound-feet, but Ford assures that the new engine's character is markedly snarlier, picking up torque lower on the tachometer and sounding significantly more aggressive, to boot.
