Roush unveils two 540-horsepower MustangsThu, 17 Sep 2009 00:00:00 -0700
The go-fast guys at Roush tore the cover off two 540-hp 2010 Ford Mustangs today.
The range-topping Stage 3 Mustang will be limited to 103 copies for 2010, while the 540RH will slot in as minimalistic approach to the iconic Pony Car for customizers. They both launch this fall.
The Stage 3 gets a new upper billet grille without the foglamps, which streamlines the look and aids cooling, Roush body parts and four-piston front brakes with 14-inch rotors. It rides on 18-inch chrome wheels, and 20-inchers are optional.
The interior gets leather seats with the embroidered signature of Jack Roush, illuminated skid plates, Stage 3 badging and a short-throw shifter. It will start around $59,945, including current Ford incentives.
The 540RH is a “sleeper” car in the words of Roush, and offers less content--but the same power--as its sibling. The 540RH has a new suspension package, rear spoiler, short-throw shifter and starts around $46,145.

Both cars use a heavily modified 4.6-liter V8 that is fortified with new aluminum pistons with increased dish to lower the compression ratio, a forged steel crankshaft and new fuel rails and injectors. Bolted on is Roush's next-generation supercharger.
