2010 Roush Stage 3 Mustang - Click above for high-res image gallery
We had very few bad things to say about the 2010 Roush 427R Mustang after spending a week with the car, but we did have a few questions. First, why not use the new TVS2300 supercharger system that debuted on the P-51A Mustang, and second, why not add a billet grille like the previous model so that there wouldn't be six different lights up front? Roush has answered our questions in the form of the 2010 Stage 3 Mustang. The new stallion atop Roush's Mustang lineup gets a 540-horsepower upgrade complete with a second-generation R2300 supercharger, forged internals, high-flow fuel rails and injectors, upgraded fuel pump and a beefier clutch. The $59,945 price tag also gets you 18-inch wheels and tires, 14-inch brakes, a Roush suspension system, various interior enhancements and a Roush body kit complete with a billet grille.
If the you're the type of person that is only interested in performance and not the rest of the fluff, Roush is also offering a sleeper package called the 540RH. Along with the drivetrain and suspension upgrades, this budget Roush only includes the rear spoiler, a short-throw shifter, and a subtle stripe package. Roush claims they have already tested the car at the drag strip (with the optional Cooper RS3 tires) and came away with an 11.8 second time slip. At $46,145, the 540RH tucks in nicely under the Shelby GT500's price tag while offering similar performance. Hit the jump for full details on both cars.
