What car is this?

I took this photo on 13 May 2011 on the road between Garda and Torbole. I was heading south and was stopped at a traffic control for roadworks and had my camera out to get photos of some sail boats on the lake when traffic started coming from the south so I quickly snapped this photo when i saw this car coming. After reading the article on the Mercedes Benz celebrations in the 2011 Mille Miglia (7 May VRL newsbrief) i guessed that this was one of the 3 Mercedes in the race. Can anyone confirm which car this is and who the driver and co-driver is.
