What is the name of this high-performance version of the 6 series coupe/ convertible, which appeared on the Moscow BMW billboard?
Moscow BMW billboard The Moscow BMW billboard was unveiled in 2008 as one of the largest and most elaborate billboards in the world. The billboard had an area of 1.5 acres and depicted an expressway, containing real, full-sized BMWs. At night, the headlights of the cars are lit up. The car models on the billboard were the BMW M Coupe, the BMW M3, the BMW M5, and BMW M6.
BMW R90S The BMW R90S is a 900cc sport motorcycle produced by BMW from 1973 to 1976. BMW commissioned designer Hans Muth to oversee the R90S, which became the flagship of the boxer engined "/6" range. Sporting distinctive two-tone paintwork, a bikini fairing and a new tail, the R90S was intended to shrug off the enduring image of BMW bikes as staid and utilitarian.
