Roush has finally taken the wraps of its latest tuning package for the 2010 Ford Mustang, with two new levels of tune available for sale this fall. Both offer up to 540 horsepower, as well as overt styling and a smorgasbord of other performance modifications.
Power comes from a supercharged version of the Mustang GT’s 4.6-liter V-8. Along with the supercharger, Roush engineers also add forged aluminum pistons, a forged steel crankshaft and new fuel rails and injectors.
The range-topping model is the Stage 3 Mustang, which Roush will be limited to just 103 units for 2010. The Stage 3 package features a upper billet grille, a full bodykit, four-piston calipers biting 14-inch brake discs and 18-inch chrome wheels as standard (20-inch wheels are optional).
Inside, designers have also gone over the top with full leather seats featuring the embroidered signature of Jack Roush, illuminated skid plates, a short-throw shifter and custom badging. Pricing for the Stage 3 kit starts at $59,945.
One of the performance bargains of the year would have to be the 540RH package, which gets the same potent powertrain as the Stage 3 Mustang but is priced from $46,145. Other elements include a new suspension package, rear spoiler and a short-throw shifter.
