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.
Precision through computer simulations, take 2jz for example, a huge and over-built in every corner of the block, but it’s extremely heavy and inefficient especially being a cast iron block.
Modern engines are smaller, lighter where mass are only necessary added based on the engine’s weak points. Materials selections have also improved for better costs to strength.
