A five-time AMA Supercross champion, Carmichael recently signed a three-year deal with MB2 Racing to compete in the NASCAR Nextel Cup championship.

Carmichael will likely follow a similar route taken by former V8 Supercar driver, Marcos Ambrose, cutting his teeth in the Craftsman Truck Series or another development class before he makes the step up to America's most popular form of motorsport.
