V configuration on a diesel engine is a questionable approach. Witness the GM debacle 20 years ago. Too much torque for the block to hold up. Hopefully MB engineers have worked this out. To my knowledge big block mfrs (Cummins, Cat, Detroit, Mack have discarded the V and gone in-line. In the pickups only Ford has the V-8. Dodge/ Cummins and GM/Isuzu (duramax) are in-line. Oh well, ANY approach is superior to these hybrids coming out.
