I guess the M3 not having a pair of up-to 1000C / 1900F hot turbos might be one explanation?
Also, I don't know how hot it gets, but the DCT has its own cooling circuit in the M3...
This might also explain why:

(Random internet speculation that the oil temp gauge in the M3 shows only a derived combo and not the actual oil temp directly...)
