So... How about those 2021 engines...
They're 2020 engines but more betterer.
Recently, in the last few years, circa 2018, technologies which use exotic cylinder and piston platings have been advanced. Computers have advanced and engineering keeps trundling along. Naturally everyone is already on board, and now before costs start going haywire, they're hoping everyone catches up, and gets to a roughly similar level.
Naturally for Renault got their toys to develop the engines late, Honda was a year and a half ahead, but Renault still had 2 years of a development head start. Renault and Honda have been relatively even in their time together, Honda ICE and packaging advantage, Renault has more MGU-K power at the expense of packaging.
Mercedes was probably 2 years ahead of everyone, and was willing to make the investment, Renault tried to cut corners and Honda needed to in order to make progress. I think what Honda and Renault have produced is worth the investment in the long run, and the timing is interesting. Ferrari is an interesting case, the engine has evolved so much, and the version that was used this year, it reminded me of when Honda started in F1, there just wasn't enough MGU-K deployment.
Engine power was there, but it just fell flat. The engine was probably designed with the exploitation of 2019 in mind, but then was forced to run with the grey zone blocked. End result too much clipping. What are the chances that Ferrari has gone to the 2015 Honda layout, and the small turbo within the V had trouble harvesting from the MGU-H. That the 'grey area' exploitation would have allowed them to make it work.
It would explain why they're banking on the intercooler, they're going to make it work some other way because the aero advantage is impossible to ignore, especially since LeClec has the concentration to get the performance from the aero.
Everyone seems to be confident of decent gains for next year. Mercedes is rumored to be bringing 25-30hp, Honda says 35-40hp?!?!*, Ferrari says it believes 30hp for the start of the season is within reach. Renault is closed lipped, nothing coming from them save they're developing a split turbo setup. Are they having trouble with the new concept? This year seems to be a limbo year for Renault because if they go split turbo it will undoubtedly be a step backwards until at least mid season. Or maybe they're just keeping their cards close to their chest, usually Renault is pretty boastful when they have a serious development. However Renault supplies no other teams, they don't have to advertise their product to anyone.
In 2025 they should release a documentary series about these engines. The development, and work that went into them really deserves to be told.
