Pursuit of Adrenaline

Combining Ford’s 5.0L V8 engine with the ROUSH Phase 2 Supercharger, the ROUSH Stage 3 delivers 750 hp, 670lb-ft of torque and a blistering 0-100km/h time of 3.6 seconds. Equipped in your choice of 6-speed manual or 10-speed automatic transmission, the power is yours to command. The 2020/21 ROUSH Stage 3 Mustang brings in a range of all new improvements for this year Inspired by Jack Roush’s legendary reputation for engineering excellence and top-notch performance, engineers and designers at ROUSH comb over every detail to create the ultimate driving experience.


The Spirit of Competition

To keep 750HP cool lap after lap ROUSH has engineered an all new Powertrain Cooling Package. Additional coolers for the engine and supercharger system work in harmony with functional vents to decrease engine temperatures. The transmission and differential receive the same treatment with upgraded coolers for a total of 6 intercoolers to give you the most engineered and track proven performance package available.

ROUSH Stage 3 Mustang 2020

Stand Out

The ROUSH Stage 3 is designed to demand attention with its aggressive stance, piano-black fascia, prominent rear spoiler, unique body components like the functional intercooler intakes, hood & fender heat extractors with ROUSH Performance graphics. This is unmistakingly a ROUSH Performance Mustang.


Put Serious Power to the Ground

The custom ROUSH-calibrated MagneRide® suspension provides unparalleled handling for uncompromising grip and a smooth ride. With multiple drive modes, the new ROUSH Stage 3 is subtle on the street and a supercar on the track/drag strip, all with a flick of a switch. Putting that power to the Road are the ROUSH Agate Grey 20" wheels wrapped in ultra high-performance tyres.
