2005 Roush Mustang Specsby Phil Whitmer
On November 2, 2004, the 2005 Roush Mustang was unveiled at the Specialty Equipment Market Association show in Las Vegas. The high-performance, customized version of the 2005 Ford Mustang GT was built by Jack Roush, owner of the Roush Enterprises family of companies. Roush Performance engineered and manufactured the Roush Mustang, using racing components and modular engines. It was available in four versions.
Jack Roush is the owner and CEO of Roush Racing, with teams competing in all three of NASCAR's top divisions. By 2010, the racing division had won over 250 motorsport events. Roush is the chairman of the board of Roush Enterprises, comprising Roush Industries, Roush Performance and Roush Manufacturing. The companies' combined expertise in racing, performance parts technology and manufacturing was used to produce the Roush Mustang. The first in-house custom-built Roush Mustang debuted in 1997.
Roush Sport Mustang
The third-generation 2005 Roush Mustang was based on the model S197 Mustang GT. The lowest-level version was the Roush Sport package. The Roush Sport Mustang had a 1960s retro look. It featured a six-piece Aerobody kit of Roush-designed aerodynamic body components. The kit included rocker panels, a rear wing, front fascia and rear valancers. Optional body components were a chin spoiler, quarter window and rear louvers, and a hood scoop.
Stages 1 And 2
The Stage 1 Roush Mustang was an appearance package, offering many of the aesthetic components of the Sport version. It featured Roush graphics, fender badges, deck lid emblem, windshield banner and embroidered floor mats. Stage 1 options included leather seats, Jack Roush-autographed gauge cluster, and billeted aluminum pedals and shift knob. Stage 2 was the more popular version, with performance suspension and handling components combined with appearance upgrades. It included racing-style front struts, rear shocks, front and rear springs, and a front sway bar. Custom Roush 18-inch chrome wheels and high-performance tires were part of the package.
The Stage 3 version was the top-of-the-line 2005 Roush Mustang version with the highest performance specifications. It featured the Roush 4.6-liter V-8 with an intercooled supercharger. The single-overhead-cam engine produced 415 horsepower at 5,250 rpm. Its maximum torque rating was 385 foot-pounds at 3,000 rpm. Its bore and stroke was 3.55 inches by 3.54 inches. The motor had three valves per cylinder with sequential fuel injection and an aluminum flywheel. The car used race-tuned Roush suspension, sub-frame connectors and performance Alcon brakes.
