Yes, that's it. As the M1 should only serve as a Homologation Model in the first place, there were plans for a common 3.0l V10. Since the numbers of cars produced was risen, that wasn't reasonable anymore and they opted for the inline 6 instead, where they could make use of other serial parts. And then they created the Procar Series with it..
On the one hand I find it quite impressive that Paul Rosche already at that time thought the V10 configuration would be the best, at least some 10 years earlier than others. On the other, it seems it was real luck how it went, because at that time, they would not know the NA engine would not have had a very long career against the TC engines.. A lot of money and manpower would have been wasted.. And surely BMW would not have been the first TC engine WC..
I think it's X's turn, since figuring out which BMW model in the late 70's wasn't that hard..
