So I made a handy timeline in every engineer’s best friend.

I know Wikipedia has a similar one, but it's not really accurate and it doesn't include all engines

I still need to work on the organization and color codes to make it more readable. I’m colorblind, so I had to pick some pretty strong colors.

Did I miss anything?

Also, pretty much every source gives a year to each engine, so correct me if something’s wrong. And some engines like the S62 was in production until much later because they sold engines to boutique car manufacturers, so I picked the latest BMW production car.
