Until now, Roush Performance had held the official performance numbers for its top-of-the-line 2015 Roush Stage 3 Mustang. Based on the potential shown by its Phase 3 aftermarket kits, we knew the numbers would be solid—and they are. Who wouldn’t like to drive off the dealer lot with 670 horsepower and 545 lb-ft of torque? That’s just want proud owners of new RS3s will have on tap.
“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 coil-over suspension system (or optional competition-tuned three-way adjustable system), and the fierce new ‘R7’ aerobody,” says the company.
