Yet again raising the standards in the Mustang world, ROUSH Performance unveiled the new 427R model with a total of 427 horsepower under the hood and ready to unleash with the turn of a key. This is the most horsepower ever offered on any version of the ROUSH Mustang.

The number 427 has been intertwined in the Ford product line for many years, both as a car model and one of the most powerful and legendary engines in their line. It is only natural that ROUSH, as perhaps the best Ford engine builder in the country, is the company to reintroduce the number to the automotive lexicon using modern engine technology.

Based on the acclaimed ROUSH Stage 3 Mustang, this version is slightly less in content but includes 100 percent of the fun factor. The 427R horsepower package is highlighted by the intercooled ROUSHcharger* system which adds 115 horsepower and 65 lb-ft of torque to the base Ford 4.6L, 3-valve V8 powertrain system. The additional power upgrade comes via a ROUSH-engineered ECM calibration which has been specially-tuned to work in harmony with the different exhaust system used on the vehicle.

Further adding to the style and performance of the 2007 ROUSH 427R is a four-piece aerobody kit which includes a stylized front fascia, front chin spoiler, hood scoop and rear wing and ROUSH 18-inch cast chrome wheels with high-performance tires and the special 427R striping kit.

The sports-tuned suspension includes all new front struts, rear shocks, front and rear springs and sway bars and the jounce bumpers. Each component was designed for both comfort and performance by the industry-leading ROUSH automotive engineers.

Authenticating the vehicle are special ROUSH fender badges, decklid emblem, a serialized engine bay plate, and a ROUSH engine build plaque personally engraved by the technician who upgraded the car in the Livonia, Mich., facility. The ROUSH 427R is available in both coupe and convertible versions.

To assist customers in creating their own personalized one-of-a-kind vehicle, a variety of options are also available which include white face gauges, interior carbon fiber design dash trim kit, short throw shifter, door sill plates, and ROUSH sport leather seating.

"The new ROUSH 427R is a natural extension of our product line," said Joe Thompson, general manager of ROUSH Performance Products. "It has more horsepower than any car we have produced in our company's history and I expect that this will become one of the most popular vehicles that ROUSH Performance has ever offered."
