The ROUSH Stage 3 Mustang is a modified stock muscle car that can produce 670 horsepower. A 5.0-liter eight-cylinder engine with a 2.3-liter TVS supercharger powers the vehicle.
The vehicle features a body kit that improves aerodynamics and handling due to the single adjustable coilover suspension system and the optional three-way adjustable system. The Stage 3 Mustang has the ROUSH Active Performance exhaust system that can adjust the volume and the tone of the exhaust noise. Furthermore, the exhaust system is fully customizable from a mobile device.
The exterior of the car features a front fascia with aero pockets, hood heat extractors, body side scoops and a front chin splitter. The car has aero aids on the side rockers and 20-inch quicksilver wheels with high-performance Copper RS3 Series tires.
ROUSH has added its badge all over the car. Badge locations include the front windshield, the dash, the floor mats, the fenders and the door sills. The car also has a ROUSHCHARGE badge, indicating the supercharger in the vehicle. ROUSH also replaced the Mustang badge on the back with its own.
ROUSH also offers customization options. Customers can add engine coil covers, ROUSH leather seating, Billet performance pedals, and locking lug nuts to the vehicle. Likewise, the wheels are upgradeable to a 20-inch polished alternative. The car comes with a three-year, 36,000-mile limited warranty.
