Hi Dean@NorthcliffBMW... unfortunately you are mistaken. That is not an M6 DTM but rather an M6 GTLM.
There is no such thing as an M6 DTM. There is however an M4 DTM and an M6 GT3.
You can see for yourself on your own webpage.

Be so kind as to look at the top left of the webpage linked above, and you will see the different versions of race cars BMW is currently pitting into the field.
The M6 GTLM had its first endurance race this past weekend at the DAYTONA 24 hours.
I hope this helped.
