With just under two weeks to go until the 2009 SEMA show, Ford decided to tease us all with an excerpt regarding the return of the infamous 5.0-liter Mustang. Word of the 2010 Ford Racing Boss 302R spread fast late this week…and rightly so. This 400hp special edition throwback to the muscle era is a race-inspired pony car well poised to assault the aggregate at any raceway. The Boss 302R will come in its base form with a sticker price of $79,000 while its upgraded sibling, tweaked with a Grand-Am Homologation package, will post a price of $129,000 for those Mustang racers looking to get into the KONI Challenge series. There’s not a plethora of “official” details (let alone imagery) released yet and Ford is being intentionally vague here, but keep reading to check out the official dealership notice sent out to let everyone know what’s coming at SEMA 2009.
