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.
Stience !
Most of the improvement come from computer based simulation and calculation.
You can have a virtual engine running in a simulation within a few percent of it’s actual real life counterpart. You can simulate dozen of designs at once in different scenarios and only build real life prototypes of the better ones. Saving time and money on iterations. Designs use less material where not needed, reducing cost and improving resistance where needed.
