My last speeding ticket was nearly two years ago while behind the wheel of a 2014 Roush Stage 3 Mustang. Considering the supercharged 5.0-liter V8 produced 575 horsepower – the lowest of the Stage 3's tunes – an encounter with the friendly folks at the Michigan State Police seemed inevitable. With the 2015 Stage 3 producing 95 more horsepower, if and when I drive the new supercharged 'Stang, another meeting with Michigan's finest seems likely.

The combination of the Ford 5.0-liter V8 and a 2.3-liter TVS supercharger turns out 670 horsepower, which should have owners of the weightier Dodge Challenger Hellcat at least a bit nervous. All that power is complemented by 545 pound-feet of torque and what is almost certainly an ear-shattering exhaust note from the quad-tip pipes.

On top of the RS3's trademark sound and speed, Roush has fitted the sixth-generation Mustang's body with a new "R7" aero kit that actually looks toned down from last year's car. 20-inch "Quicksilver" wheels are standard, although Roush is offering a pair of optional designs. Either way, Cooper RS3 tires are the rubber of choice.

Prices for the Roush Stage 3 Mustang start at $21,995, not including the $32,300 starting price of a Mustang GT donor car. ROUSH Stage 3 Mustang Produces 670 HP

May 7, 2015 – PLYMOUTH, MICHIGAN – ROUSH Performance is excited to announce final horsepower ratings for the all-new 2015 ROUSH Stage 3 Mustang. The RS3 is cranking out a heart-racing 670 horsepower and 545 lb-ft of torque to deliver the ultimate driving experience.

All 670 horsepower are created as a direct result of the powerful combination of Ford's 5.0L V8 engine with ROUSH Performance's dynamic new 2015 2.3L TVS supercharger.

The new ROUSH Mustang's generous power ratings impeccably compliment the RS3's list of standard and optional features, including the ROUSH Quad-Tip exhaust (with optional ROUSH Active Exhaust System), standard single-adjustable coilover suspension system (or optional competition-tuned 3-way adjustable system), and the fierce new "R7" aerobody.

The 2015 ROUSH Stage 3 Mustang is not just a car – it's an experience. The RS3 truly bridges the gap between road car and race car, putting drivers behind the wheel of the ultimate uninhibited muscle car.

Jack Roush's vision shines through the 2015 ROUSH Stage 3 Mustang's perfect combination of 670 horsepower with meticulous handling and braking capabilities, providing the driver access to the robust attitude and performance of a racecar, while maintaining a comfortable and uniquely ROUSH driving experience.
