Not an expert, but the dry weight of the Korean diesel engine is said to be ~500 kg heavier than the MTU. As a long stroke engine it‘s also bigger in dimensions.I also have another question regarding the Doosan DV27K's dry weight (≈2550 Kg) in comparison to the MTU MT883 Ka-500/501 (≈1800 Kg). First of all, are these numbers true? If so, why is there such a significant difference in weight between the two engines? Do the Germans really have alien tech? What dry weight can we expect from BATU? Sorry for all the questions, I'm really not knowledgable on this subject.
MTU designs and builds diesel engines for armored tracked vehicles since 1918. That‘s over 100 years of experience and one premier example of German engineering, not alien tech, they‘re simply very good at what their doing.
