The 2013 BMW M6 Gran Coupe has sidled in front of our spy photographers' lenses, and it looks good: like the Gran Coupe, but meaner. We're looking forward to seeing how it stacks up to the M5 on track.

A 2013 Shelby GT500 prototype will cross the blocks at Barrett-Jackson this month, though it'll be destined for limited use, as it can't be licensed for the street. Still, with a Carroll Shelby-driven pedigree and its status as a pre-pro version of the hottest street Mustang yet, it'll likely be sought after by collectors.

Finally, we have a recall on the 2012 SRT8 Charger and 300 sedans, due to a mis-configured tire pressure monitoring system that doesn't warn of low pressures until they're way, way too low.
