NASCAR's second-string Nationwide Series won't debut its own version of the Car of Tomorrow until at least 2010, but they officially began testing of their "new car" on Monday. And who's the coolest prototype on the track? Dodge rolled up with this NASCARed-out Challenger, and I think it looks hot as hell. From the fenders back, it looks pretty much like any other stock car, because of the way the cars' lines have to conform to specific body templates determined by NASCAR. But the sanctioning body has modified the rules governing the forward sheet metal, so it appears that the nationwide CoTs might actually be permitted to run real front clips instead of just stickers. See more pics of the Challenger testing at Richmond International Raceway below the jump, along with the other manufacturers' offerings—the Malibu, the Fusion (though Ford will supposedly be running a Taurus), and the Camry.
