The BMW inline 6 were the best engines ever. Their inline 4 and other are a strong contender for the worst engines ever.

I assume you’re talking about the n52 vs n20. I’ve had both engines as daily drivers, and they’re both fine. The n20 has a bad rap due to early models failing from a timing chain guides breaking.

I miss my E39 530 every time I drive. My next 90s Jag is also going to be a straight-six; the V12 is glorious but heavy.
