After being previewed late last year, official specifications for the range topping 2015 Roush Mustang Stage 3 have just been revealed.
At the heart of the Roush Mustang equipped with the Stage 3 performance package is the American muscle car’s standard 5.0-litre V8 engine. However, the engine has been joined with a 2.3-litre TVS supercharger from Roush. When combined with a new exhaust system, the latest and greatest Roush pumps out 670 hp and 545 lb-ft of torque.

Alongside the engine and exhaust modifications, the 2015 Roush Mustang Stage 3 has been fitted with single-adjustable coilover suspension but a 3-way adjustable system is also offered. Elsewhere, the Roush Mustang Stage 3 is adorned with an aggressive and bespoke bodykit incorporating new front and rear bumpers and fascias as well as a bonnet featuring a prominent power dome.
Beyond the Stage 3 kit, Roush offers its standard Mustang, the Stage 1 and Stage 2 packages. The entry-level model features the Mustang’s base 3.7-litre V6 while the Stage 1 uses the 2.3-litre EcoBoost turbocharged four-cylinder and the Stage 2 uses the 5.0-litre V8.
