Eight-cylinders, 420 horsepower, the BMW M3 E92 had been the fastest M3 so far. Another exclusive highlight was the M3 GTS, specially designed for motor racing and the four door M3 CRT. The M3 of the fourth generation was also a car for winners. In the first “DTM-Year” after a 20 year pause the BMW M3 DTM celebrates a spectacular season with Bruno Spengler winning the Driver Championship. This film is the fourth part of our five part series about the most successful model of BMW M.
