The American Mustang->ke428 tuners at Roush->ke1434 Performance have announced details about their plans to upgrade the all new 2011 pony car. There will be two different versions of the modified Mustang, appropriately called Stage 1 and Stage 2; with both starting out with the blue oval's new 5.0 Liter power plant producing 412 HP and 390 lb-ft of torque. The Stage 1 package will consist of nothing more than a few aesthetic changes including the Roush body kit, meanwhile the Stage 2 kit adds a few new suspension parts to improve the 21st century pony car's handling package.

According to the man himself, Jack Roush, "the 2011 ROUSH Stage 1 and Stage 2 Mustangs will represent an incredible value by blending appearance and handling with an amazing base Ford engine package... I expect that the 2011 Stage 1 and Stage 2 Roush Mustangs could come close to matching the performance of some Roushcharged Mustangs we have offered in prior model years which will make them extremely exciting to drive and at a reasonable starting price point." While this is well and good for now, Roush fans are accustomed to a blower under the hood, and they can rest assured because the team is hard at work with a few power adding parts which will be available sometime this summer.

Press release

ROUSH Performance, the leader in specialty Mustang builds with more than 16,000 vehicles on the road, unveiled the timeline for producing their highly-anticipated 2011 Ford Mustang conversions.

In April, shortly after Ford’s Job 1 begins on the 2011 model year Mustang, ROUSH® will offer their Stage 1™ and Stage 2™ versions. Using the new Ford 5.0-Liter, V-8 engine, both of these cars will have 412 horsepower and 390 ft.-lb. or torque, all while reaching an estimated 25 highway miles per gallon of fuel economy. Also new for the 2011 model year is the standard six-speed transmission, something that Mustang fans have clamored for over the past several years.

The ROUSH® Stage 1™ package consists primarily of aesthetic changes such as the addition of the OEM-quality ROUSH body kit. The ROUSH® Stage 2™ adds a suspension and handling package in addition to the appearance upgrades.

“The 2011 ROUSH® Stage 1™ and Stage 2™ Mustangs will represent an incredible value by blending appearance and handling with an amazing base Ford engine package,” said Jack Roush. “I expect that the 2011 Stage 1™ and Stage 2™ ROUSH® Mustangs could come close to matching the performance of some ROUSHcharged™ Mustangs we have offered in prior model years which will make them extremely exciting to drive and at a reasonable starting price point.”

For powertrain models, such as the ROUSH® 427R®, the engineering team is already hard at work developing the 2011 model year ROUSHcharger® and determining what modifications can be done to the 5.0-Liter engine. ROUSH® 2011 model year powertrain vehicles, however, are not likely to be available until late summertime.

“We have a history of increasing the horsepower on each model year 427R® Mustang, and that should continue with the 2011 as well. However, exactly what the horsepower and torque numbers will be is too early to tell at this point as the engineering teams are still working through a myriad of details on the new five-liter engine,” explained Jack Roush.
