Last year we saw the team from Sport Auto head onto the Nurburgring in the RWD BMW M4 Competition where they managed to set a time of 7:30.79.
Now the xDrive variant is available so they had another go with some extra traction and drive.
The quickest lap they could achieve was 7:28,57 which means it is more than 2 seconds faster than the rear-wheel-drive sibling. We thought it would be a bit more to be honest but what is also impressive is that it fractionally beat their time set in the M5 CS of 7:29.50.
We are expecting to see a new M4 CSL this year which will not only be lighter but more powerful than the M4 Competition so we should see an even more rapid lap time.
