Most of the production engines still use tumble flow combustion

For reference: Nissan e-power with recuperation ~50%: https://www.nissan-global.com/EN/INNOVATION/TECHNOLOGY/ARCHI...

Mahle ~45% with pre-chamber: https://www.mobilityengineeringtech.com/component/content/ar...

Toyota dynamic force engines ~40% : https://www.thedrive.com/tech/18919/toyota-develops-worlds-m...

Toyota's newest engines claim even more: https://global.toyota/en/newsroom/corporate/40850156.html

Honda hybrid ~40%: https://hondanews.com/en-US/honda-automobiles/releases/relea...

Startup Carnot engines claim 70% efficiency: https://carnotengines.com/technology/

The geometric compression limit for F1 is 18:1. They make it sound like they can go farther.

Mercedes crossed 50% thermal efficiency in 2018 with their F1 engine: https://www.roadandtrack.com/motorsports/a15049580/mercedes-... Their recent interviews suggest they are up by 2 to 3% on that

Honda did too but they never marketed the explicit number.

what are you even talking about? A lot of stuff is clearly laid out on how they achieved better efficiency.

You can get more power out of NA with better materials you've stated but not efficiency.

F1 wanted more road relevancy and hence ended up with turbo-charging and Fuel limits

Ferrari's partner MAHLE has pre-chamber ignition productized for OEMs: https://www.mahle-powertrain.com/en/experience/mahle-jet-ign...

I think, Maserati MC20 has this tech.
