Roush Unveils 2010 Roush 540RH, the Ultimate Sleeper Mustang

Another vehicle unveiled by Roush Performance this week is a Sleeper Mustang of sorts



Another vehicle unveiled by Roush Performance this week is a Sleeper Mustang of sorts, the 2010 Roush 540RH, a limited content model with the same powertrain from the Roush Stage 3 Mustang and minimal Roush accessories.  The 2010 Roush 540RH will have the same ROUSHcharged 4.6-liter V-8 with forged internals as the Stage 3 model and only a ROUSH rear decklid spoiler and short throw shifter with white or black ball to be identifiable as a Roush Mustang.  The 540RH is intended to be a 'sleeper car' as explained by Roush with it specifically designed for the buyer who wants the Roush performance and not the Roush accessories.  This gives the new owner the opportunity to create his or her own unique Mustang with the power already taken care of.  With an MSRP of $46,145 it will be a costly starting point but well worth it for those wanting a solid powertrain in place.

Testing this vehicle at Milan Dragway in Michigan Roush Engineers recorded an 11.8-second quarter mile time at 121 mph.  Like I said in the title this is the Ultimate Sleeper Mustang.

Press Release:

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 bumper, 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.
