Design
The engine block itself is derived from the inline 6 cylinder M103 and M104 gasoline engines, with the Diesel crankshaft differing somewhat from the gasoline versions. Prior to the merge with Mercedes-Benz, AMG Affalterbach utilized the OM603 and OM606 crankshafts in modified form, for the 3.4 litre and 3.6 litre AMG M104 gasoline engine variants.
