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.
Advancements have come from materials, intake and exhaust efficiencies. Motor size doesn’t matter like it used to back in the day of carbs, the old way was crude and so inefficient compared to the modern stuff.
The gains with the modern stuff is so small and minor, a few hp here and there but over the course of decades it became impressive. Turbo’s were never really all that great until recently and they have so much room to go…plus hybrid systems, you’ll be looking at extremely quick cars.
Problem is EVs are taking over, so much faster and r&d into ICE is going to stop.
