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.
Forced induction with stronger materials or build design. That’s literally it. You might have a few percentages from increasing efficiencies but it really is nothing but shoving more air into the engine and the block being able to handle it.
