Right before Christmas, German magazine Autobild gave themselves a little present: they took all of the current BMW M models and tested them on the circuit to see which one was the fastest. All of the tests were done on the Sachsenring circuit in Germany and, surprising or not, the fastest model turned out to be the M3 CRT (E90) . In fact, according to Autobild, not only was it the fastest from all the models tested, it was also the fastest M Car they have ever tested on the Sachsenring.
The M3 CRT lapped the circuit in 1:38.87 , closely followed by the M5 with a lap time of 1:38.90 and the 1-Series M Coupe with a time of 1:40.18. The list continues with the M3 in coupe, sedan, and convertible forms and ends with the X6M and X5M . Both SUVs were faster than the old E60 M5.
