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 RS3 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.
