As Audi prepares to unveil its updated 2013 Audi R8 at the 2012 Moscow International Motor Show, the carmaker released a video detailing what’s new. We've already shown what the model will look like — it gets new headlights, front bumper and front grille designs — and there's a new transmission, too. The new double-clutch seven-speed S-Tronic automatic transmission will help the R8 accelerate from zero to 62 mph in 3.6 seconds, which is a smidge faster than the 2012 Audi R8 GT coupe. Check out the video below. We should have more information on the 2013 R8 early next week.
