With the launch of the 2010 Ford Mustang and the car’s 45th anniversary coinciding neatly, it was obvious Steve Saleen, who is synonymous with all things ‘Stang, would have something up his sleeve.

His new company, SMS Supercars today released a sketch of its new go-fast Mustang. It comes in two versions, the 460 and the 460X. Fittingly, he released them at the Mustang anniversary party at Barber Motorsports Park in Birmingham, Ala.

Saleen paid special attention to the air induction, fascias, splitters and diffuser to customize the new Mustang. It also gets new suspension geometry and brakes. Inside is Alcantara and leather, with hand-stitching on the interior panels.

The 460 comes with a 4.6-liter V8 making 470 hp and 427 lb-ft of torque. The 460X makes 655 hp and 600 lb-ft from a 5.0-liter V8. They both employ the SMS 296 supercharger.

The 460 comes with five-speed manual or automatic transmissions, and the 460X gets a six-speed manual. Expect the cars to reach 60 mph in the low four-second range.
