Roush’s new 427R 2010 Mustang is powered by a 4.3L V8 that has been supercharged to produce 435-hp. Not bad seeing as it allows you to do 0 to 60 mph in the low 4-second range. But what if you feel that isn’t enough horsepower for you to put the all the other pony cars on the road to rest.
Well, Roush today introduced something called the 2010 Roush Stage 3 Mustang, which uses the same engine from the 2009 Roush P-51B Mustang. However, with a couple of modifications, including the next-generation R2300 ROUSHcharger, the engine now produces 540-hp with a peak torque of 510 lb-ft.
Suggested retail price for the 2010 Roush Stage 3 Mustang comes in at $59,945. Roush will produce a limited 103 units of the Stage 3 Mustang so you better hurry if you want one.
However, if you don’t want to pay all that money and don’t really care about 18-inch wheels and a body kit, Roush is also offering the 540RH which it says is “intended to be a ‘sleeper’ car.” It gets the same 540-hp along with a new suspension package, front and rear springs, front and rear stabilizer bars and jounce bumpers – all starting at $46,145.

2010 Roush Stage 3 Mustang / 540RH:
2010 Roush Stage 3 Mustang:
ROUSH® introduces a pair of new 2010 Mustang models, each with 540 horsepower and 510 lb.-ft. of torque ready to be unleashed by the touch of the throttle.
The 2010 ROUSH Stage 3™ Mustang will once again take its rightful place atop the hierarchy of Jack Roush’s lineup. The vehicle comes fully-loaded with the ROUSH body components; resonator exhaust; four-piston front brakes with 14-inch rotors and painted rear calipers with slotted rotors; and the new upper billet grille which removes the fog lamps and streamlines the appearance of the new Mustang while improving cooling performance. Interior enhancements include ROUSH leather seats with an embroidered Jack Roush signature; four-piece performance pedals; ROUSH illuminated sill plates; short throw shifter with black or white ball; and a new interior Stage 3 badge with the car’s serial number engraved.
The 2010 ROUSH Stage 3 Mustang will ride on 18-inch chrome wheels with high-performance Cooper RS3 tires; 20-inch chrome wheels with Cooper RS3 tires are one of the few options available on this model. The suspension package includes ROUSH front struts, rear shocks, front and rear springs, front and rear stabilizer bars and jounce bumpers.
“The ROUSH Stage 3 Mustang has traditionally been among the halo vehicles of our lineup and I’m really proud that it sits atop the pecking order once again,” said Jack Roush. “This new iteration of the Stage 3 represents our highest horsepower and most sophisticated ROUSH Mustang yet, and is sure to resonate among our fans.”
The suggested retail for the 2010 ROUSH Stage 3 Mustang is $59,945*. The 2010 ROUSH Stage 3 Mustang will have a limited production run of only 103 vehicles.
The second Mustang unveiled with the 540 horsepower powerplant is the new 2010 ROUSH 540RH™, a limited content, full powertrain vehicle. Also known as the Hammer®, this car comes armed with massive horsepower, a ROUSH rear decklid spoiler, and short throw shifter with a choice of white or black ball, the 540RH is a stoplight slayer.
Proving just how quick this car can be on the optional 18-inch Cooper RS3 tires, ROUSH engineers recorded an 11.8-second elapsed time at 121 mph during testing at Milan (Mich.) Dragway in early September.
“The new ROUSH 540RH is really intended to be a ‘sleeper’ car,” Roush explained. “It will be purposely built with minimal content as it was designed for the buyer who wanted the ROUSH horsepower but with a blank canvas that can be customized into their own personal one-of-a-kind ride.”
The 2010 ROUSH 540RH has a new suspension package which includes front and rear springs, front and rear stabilizer bars and jounce bumpers, and a subtle tone-on-tone striping package. All this comes with a suggested retail starting at $46,145* when built on a base Ford Mustang GT chassis.
Both the 2010 ROUSH Stage 3 Mustang and the 2010 ROUSH 540RH Mustang use the same engine that debuted in the 2009 ROUSH P-51B™ Mustang. In order to get this type of power from the Ford 4.6L, 3-valve engine, ROUSH technicians replace many of the internal components with stronger parts including forged aluminum pistons (with an increased dish to lower the compression ratio from 9.8 to 8.6), forged steel H-Beam connecting rods and a forged steel crankshaft. The fuel rails are changed, as are the fuel injectors and an upgraded fuel pump. ROUSH also upgrades the clutch and includes a custom-calibration for the ECM to manage the performance of the next-generation R2300 ROUSHcharger®.
As is standard with all new ROUSH Mustangs, both cars will come with the anti-wheel hop kit installed during the assembly process. This part (No. 401788) is an outstanding addition to any 2005-2010 Ford Mustang GT.
Both vehicles are covered by a 3-year/36,000-mile warranty and will be available with a manual transmission only. The 2010 ROUSH Stage 3 is expected to start production by the end of September; the 2010 ROUSH 540RH should start showing up on dealer lots in October.
