The current plan is: "General Dynamics has been working on a drop-in diesel engine to replace the gas turbine engine. It is smaller than the turbine, 14% cheaper to operate per mile, and has a four-fan cooling system that is to greatly reduce the tank's heat signature.[132] General Dynamics is offering the Tognum America/12V883 diesel engine with new Diehl 570P3 tracks." Didnt know that (obviously). On the other hand they have the "current" plan for a while now and I guess they are not only happy with the gas turbine decision and changing to another engine does pose some serious challenges. I wonder whether the reference to new "tracks" in connection with a new engine points at a greater rework than just putting in a new engine. The idea of a multi-fuel engine made a lot of sense back in the start of the cold war. A unit might be deployed with allied forces that used different fuel, far away from any american supply line. Especially if you consider the difficulty of getting fuel transported across a literal ocean and how much infrastructure exists in Europe. But in 2020 they focus on one fuel for all land vehicles, one fuel for ships, one fuel for aircraft. Where the tanks a sent, nearly no secure fuel infrastruture exists. So needing less of a common fuel makes more sense. quote:
ORIGINAL: postfux While you can fit a much bigger engine in an existing model within some months of development you might decide to continue a proven set of components in a "new model" just because the development cost of the existing model is high after several reworks. There is no connection in the game between design decisions and the fact you are getting a new model. I am 90% sure that design passes do not increase the design cost. Only adding totally new model line of a type causes a increased price - and only for new models. So one of us has a faulty asumption, and there is only a low chance of it being me.
