2014 Chevrolet SS arrives first for NASCAR, then everyone else late next year

It only took 17 years after General Motors killed the last rear-wheel-drive Chevrolet Impala sedan for GM to decide that maybe a few of its more devoted shoppers wanted such a car (not counting the new, police-only Caprice.) This blurry prototype shows what Chevy will race in NASCAR next year, and hints at what it will offer as the 2014 Chevrolet SS sedan late in 2013. What's one more year at this point anyway?
