BMW was one of the biggest corporate supporters of the 2012 London Olympics, earning the right to be its official car sponsor.

BMW supplied about 4,000 vehicles to the London Olympics organizers, everything from motorcycles to electric Minis to hybrid 5-Series sedans to diesel X5 SUV's. Our sister site Translogic went to the Olympics to get a taste of the breadth and depth of the BMW Olympic fleet.
