While Chevy's racecars in the NASCAR Nextel Cup were already based on the Monte Carlo, next season's will be based on the Monte Carlo SS. What's the difference, you ask? In terms of shape, nothing. In terms of appearance, the "SS" moniker will now appear on the vehicle. We know, we know… hardly worth mentioning, right? The only item of real note here is that the Monte Carlo SS now comes with a new 5.3L V8 that produces 303 hp and 323 lb-ft of torque. So the production MC SS has a V8 and it's a coupe, just like its racecar cousing. It's not RWD, but it still has two out of three things in common with Jeff Gordon's ride. The Dodge Charger, on the other hand, only shares its drive wheels with its distant racing kin, and the Ford Fusion and Fusion NASCAR racer aren't related at all. Can anyone remember the last NASCAR racecar to share its body style, cylinder count and drive wheels with the production vehicle on which it was based?
