The horsepower wars are far from over. Squaring off against the mighty Dodge Challenger SRT Hellcat and the Chevrolet Camaro ZL1, Roush officially revealed that its 2015 Roush Stage 3 Mustang will spit out 670 hp and 545 lb-ft of torque from its supercharged 5.0-liter V-8 engine.

The Roush Stage 3 achieves this gut-twisting horsepower through the addition of a 2.3-liter TVS supercharger to the stock naturally-aspirated 5.0-liter V-8 mill. This is a boost of an incredible 235 hp and 145 lb-ft of torque over the standard 2015 Ford Mustang GT.

To make sure the rest of the world knows the Stage 3 packs some serious heat, the newest Roush monster comes equipped with a special quad-outlet exhaust, with a active dual-mode exhaust as an optional extra. In traditional Roush fashion, the exterior of the Stage 3 has been modified to match the outlandish power under the hood. The "R7" aero kit adds an aggressive appearance to the front, rear, and sides of the 2015 Ford Mustang.

To ensure the Stage 3 can handle itself when the road turns twisty, Roush fits the Stage 3 with a standard height-adjustable performance suspension. An optional three-way adjustable coilover suspension is also available.

Prices for the new 2015 Roush Stage 3 Mustang starts at $21,995, not including the base price of a regular 2015 Ford Mustang GT itself.
