ROUSH is the first to market with a complete performance package for the new 2010 Mustang GT. The ROUSH 427R Mustang comes with more power, a new look and improved handling.

Power is increased to 435hp and 400 ft-lbs of torque thanks to a ROUSHcharger, which features a significantly improved intercooler setup over previous ROUSH models. The intercooler is a single core cross-flow unit with better cooling and is much larger than past versions. The reservoir is also twice as large as on past models. Even better, the intercooler sits higher in the vehicle to help reduce damage from road debris. ROUSH also went to great lengths to insure all the parts were top quality, not only for durability, but also to give that OEM appearance.

The ROUSHcharger comes with a 3 year/36,000 mile warranty.

Also a part of the 427R package is a new suspension setup and 18-inch cast (sigh not forged) chrome wheels. A set of 20-inch wheels is a $1,115 option. The ROUSH suspension also comes with a ROUSH wheel hop reduction it, when the new suspension is installed at the factory.

The 427R package wouldnt be complete without a new aero kit to set the car apart. The 427R kit comes with a new front fascia (with integrated lights) and front splitter, a rear bumper, side skirts and a three-piece rear wing.

The complete 427R also includes other odds and ends and is priced at a reasonable $14,156.

PRESS RELEASE



The ROUSH 2010 427R Mustang will be the first in the lineup of new ROUSH 2010 Mustangs to have a ROUSHcharger installed which boosts the horsepower to 435 and offers 400 lb.-ft. of torque. This is the first time that ROUSH has been able to offer a supercharged vehicle at the launch of a new body style.

Under the hood customers will see many differences in the ROUSH 2010 427R Mustang compared to previous years. One of the biggest changes is that the long air induction tube that wrapped around the engine was eliminated making a much cleaner appearance under the hood. The intercooler reservoir has more than twice the volume of previous generations, and the intercooler itself is a single core cross-flow radiator which means more efficient cooling. It is substantially larger than on prior model years, and is now raised higher off the ground which should offer much less potential for road debris damage. Even the hoses on the ROUSH 2010 427R have seen an upgrade; they are all now 100 percent molded rubber with abrasion resistance and have imprinted markings for things like the clamp locations. This makes for even more of a true OEM appearance under the hood, and ROUSH has taken this factory appearance to the degree of matching the Ford grain on the OEM radiator reservoir and duplicated it on the one used by the intercooler. Although much of the 4.6L, 3V powertrain components are a carryover from that used on the 2005-2009 ROUSH Mustangs, customers will notice much more refinement and OEM-level quality materials and appearance on the new ROUSHcharged engines. This new 427R is be covered by a 3-year/36,000 mile warranty.

The 2010 427R includes an appearance package which is comprised of several components such as a new front fascia and front splitter, rear fascia, side splitters, and a three-piece rear wing. The new rear fascia is a one-piece design which improves the fit and finish; the part is injection-molded by ROUSH Manufacturing in an OEM-level TPO plastic which, in the black color with decorative grain, will help reduce rock chips. The vehicle rides on 18-inch cast chrome wheels with high-performance Cooper Zeon tires, with a new 20-inch cast chrome wheel as an available option.

This package also includes an all-new suspension package to greatly enhance the handling of the vehicle and turn that daily commute into a slalom course. The ROUSH chassis engineering team has driven tens of thousands of miles on the streets and tracks to create the best blend of comfort and handling, and claim that this is the best suspension package they have come up with yet for the Mustang. A ROUSH wheel hop reduction kit will be included with all vehicles that have the upgraded ROUSH suspension package installed at the factory.

Ive driven every generation of ROUSH Mustangs and there is no question that these cars keep improving over the years. Our engineering teams never sit back and say,Thats it. We are done working on this now. They continually refine the components, whether it is in the engine, suspension, or any other part of the car. They are always thinking and testing and improving and creating the ultimate Mustang for the muscle car enthusiast. I think that there is no doubt that the ROUSH 2010 Mustang is our finest effort yet, Roush stated, adding that he will shortly be using one as his personal vehicles while traveling the NASCAR circuit.
