2021 Roush Stage 3 Mustang

Starting From $58,000

The Ultimate Pursuit of Adrenaline

25 years ago, the first ROUSH Performance Mustang hit the streets and set the bar for earth-shattering performance that was bred on the track. Today, the 2021 ROUSH Stage 3 delivers 750 horsepower and 670 lb-ft of torque to deliver a blistering 0-60 mph time of 3.6 seconds. Equipped in your choice of 6-speed manual or 10-speed automatic transmission, the power is yours to command. 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. For those craving even more power, a new 775 horsepower optional upgrade is now available for 2021.

Design Meets Functionality

Everything on the 2021 ROUSH Stage 3 is designed to demand your attention on the street and to function on the track. The ROUSH Powertrain Cooling Package is standard for all 2021 ROUSH Stage 3 Mustangs. Behind each of the high flow corner pockets is an auxiliary cooler. The high-gloss fender vents and hood vents allow hot air to quickly escape the engine bay. The ROUSH Chin Spoiler separates airflow above and beneath the Mustang, working to reduce overall aero drag. The included market-exclusive Wheel Shrouds separate the turbulent wheel well airflow from the body’s exterior slip stream. An optional Active Carbon Fiber Rear Spoiler is available for those who want to dominate on the track.

Power to The Pavement

With 750HP beneath your right foot, our ROUSH-calibrated MagneRide Suspension is specially engineered to deliver unparalleled performance on the street and on the track. Each ROUSH Stage 3 is equipped with Continental ExtremeContact Sport tires to maximize your Mustang’s performance capabilities in both wet and dry conditions. These two incredible feats of engineering paired together allow the Stage 3 to push 1.07Gs on the skid pad.

Upgraded Cockpit

The inside of your ROUSH vehicle is where you the driver spend most of your time (optional Amaretto leather seating shown). Featuring premium leather seating with several upgrades and color options, custom dash gauges, a calibrated boost gauge, illuminated door sills, and more, the 2021 ROUSH Stage 3 Mustang is upfitted with premium accessories to make every ride feel special.

Make it Your Own

Our optional components allow you to take your ROUSH Stage 3 Mustang to the next level. New for 2021, we are releasing an optional calibration that boosts horsepower output to 775 horsepower. This is the most power ever available on a Stage 3 Mustang. The optional Active Aerodynamic Carbon Fiber Spoiler is an electrically actuated rear spoiler that can be adjusted based on your driving preferences and is integrated with ROUSH Active Exhaust modes.
