BMW has taken the covers off its M3 based challenger that will compete in the Deutsche Touringwagen Masters or DTM series again this year after a many year hiatus.  BMW will fight it out with the Mercedes Benz and Audi cars that have traditionally taken part in the DTM series.  Though it has been a long time since BMW has raced in the DTM series, it has been racing in the World Touring Car Championships till recently apart from being in F1 till a couple of seasons ago.  BMW is confident that it can take the fight to the competition right from the first race.
