The examples being lets say BMW E46 M3 and the new BMW G80 M3. The E46 has a 3.2 i6 NA that makes 338hp, the G80 M3 has a 3.0 i6 twin turbo that makes 510hp.
What technological advancements have been made, other than the turbos and 20 years, that separate these 2 cars?
If you know something really technical feel free to share.
The G80 has two big turbos. A more interesting discussion would be around how powerful small engines have become, like the Yaris GR with a 1.6 and 500-600bhp some are running.
