ylk1·anno scorso·discussThe geometric compression limit for F1 is 18:1. They make it sound like they can go farther.
ylk1·anno scorso·discussMercedes 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 thatHonda did too but they never marketed the explicit number.
ylk1·anno scorso·discusswhat 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
ylk1·anno scorso·discussFerrari'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.
ylk1·anno scorso·discussThey've detailed their work on engine/MGU-K/MGU-H/ESS here: https://global.honda/en/tech/motorsports/Formula-1/
ylk1·anno scorso·discussThe only manufacturer to release any details about their powertrain technology.
