As far as I know, each DTM car has a unique livery, at least it has been this way over the last few years. (This is probably one of the things that F1 could learn from DTM.) Anyway, the new liveries will be a nice addition to BMW joining the club.
Agreed with @matt90. Maybe their “A” team drivers will get the traditional BMW Motorsport livery. I wonder which drivers will drive for the main team. Tomczyk; Spengler and Priaulx would probably be the possibles..
I reckon Bruno Spengler will have the BMW Motorsport livery, his car’s livery last year consisted of little more than some Mercedes stickers. Most of the other BMW drivers I suspect will have their own sponsors on, Tomczyk with Schaeffler Group and Priaulx with Crowne Plaza.
