its not because they are going back to heritage. BMW makes a lot of I6 engines. it saves cost to make a M4 and a 335i more similar with production. look at the new M engine and look at a 335i engine.

the problem is not a 8 cylinder Vs 6 cylinder thing. its these new small displacement turbo engine. its completely new to M cars!

the M3 v8 is more similar to the E46 I6. than the E46 I6 is to the F80 I6 turbo

Remember this about shared components?

The M3/M4 is brimming with dedicated parts - Albert Biermann says that the content of standalone components amounts to roughly 50 per cent.

Significant cost-cutting is achieved when the percentage of shared components between regular 3er model and M3/M4 model is increased from ~20% to 50%.
