The wild boys over at Roush Performance have finally mastered a turbocharger.

A new app lets you turn your Roush Mustang from a mild mannered sports car into a roaring lion at the touch of a button.

The Roush Stage 3 s550, which makes 670 horsepower and 545 lb-ft. of torque, has an asking price of $65,255, which seems like a lot of car for the money.

This custom s550 is a new limited-edition model made by Roush and Military Autosource that will be offered exclusively to U.S. Military through overseas dealerships.

These forged rollers from Vossen meld perfectly with the black paint and angry body kit of this 2015 Roush Mustang.

This RK Motors Charlotte Mustang is a clear reminder that the appeal of the Roush Stage 3 didn’t start in 2015.

Although we’ve already gotten a lot of the details on the 2015 Roush Stage 3 Mustang, a new video posted by the company gives us a more up-close look at the car’s features.
