All-New 2015 Roush Stage 1 Mustang

The All-New 2015 ROUSH Stage 1 Mustang Crosses New Boundaries



"We're excited to incorporate the new Ford I-4 EcoBoost platform into our line-up with the 2015 ROUSH Stage 1 Mustang," says Jack Roush.


  • With the introduction of the 4-cylinder EcoBoost Mustang, ROUSH has taken the opportunity to provide an even more diverse selection of models. The 2.3L turbo-charged engine provides both more power and fuel efficiency than the already impressive Ford 6-cylinder Mustang. The base 2015 I-4 EcoBoost Mustang is rated at an whopping 21mpg city / 32mpg hwy and 310hp / 320lb-ft.
  • ROUSH has taken this system and added its unique vision for the vehicle, with 17 core component upgrades, including an aggressive front fascia, front grilles, a front chin splitter, rear decklid spoiler, the 2015 ROUSH Mustang Exhaust System with Quad Tips, and more. There is also a wide variety of optional components, including side rocker graphics, 20-inch wheels with ultra high performance tires, hood graphics, instrument gauge cluster, body side scoops, and the innovative ROUSH Active Performance Exhaust System.
