> Now it turns out that making 2 different engines is actually pretty wasteful, and it's way more efficient to make 1 engine Generally speaking gas/diesel engines are used across several models, mass market manufacturers aren't making bespoke engines for one specific vehicle trim that isn't used elsewhere. The overall direction is further standardization of platforms (esp with electric vehicles) but large companies like Toyota, Ford, etc. are going to have a variety of engines available for engineers to slot into vehicles to handle different use cases. I'm not terribly interested in counting but here's some examples of the variety: https://en.wikipedia.org/wiki/List_of_Toyota_engines https://en.wikipedia.org/wiki/List_of_Toyota_engines https://en.wikipedia.org/wiki/List_of_Ford_engines https://en.wikipedia.org/wiki/List_of_Ford_engines > I'm not in the automotive industry, so I don't know all the details, and I might be wrong on the above reasoning, but this is what I got from it. I'm sorry but your speculation is pretty far off base and isn't based in fact.
