Ferrari Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

It's great to see the Ferrari turbo for the first time.
So from 2016 onwards, Ferrari took their intercooler out of the V and opted to insert the compressor and its entry air ducts there instead. Few people know that or want to believe it : )
(they didnt put it at the front of the V obviously, they pushed it in the back of the V).
So their general packaging philosophy remained the same since 2014.

So officially, F1 has recognised in their articles that ferrari's new upgrade includes a new mgu-h. The Amus theory of "shifting to 800Vs" is losing creditibility in my mind..
Unless somebody with the Ferrari technical team reveal the operating voltage of the system, I would imagine that they are already using in excess of 800volts, in WEC Porsche were already using a 900volt system before they stopped at the end of 2018.

I’m surprised that the FIA haven’t mandated a specific operating voltage, as that seems to be how they manage ‘progress’ ….
Common sense is not as common as stupidity, but it is better to be uninformed than to be mis-informed...

All teams in F1 use high voltage DC links at around 800V (depending on the energy store State of Charge) - as does FE (and other derivatives) as higher voltages are more efficient; they must be under 1000V by FIA regulation; and they use 1200V Silicon Carbide switches. 400V based systems are either legacy or carry over in current road vehicles due to cost or design cycle.

It's a first, but Amus was clearly bullshitting then. On a brighter note, even that 8 hp release has shown visible progress on track as well as data. I'd love to see what the double of that would do.

Do you have any more details or references to this?

I’m really looking forward to next year’s power unit. But as far as this current upgrade that they just put in Lecs car goes, I think the gains we’ll see are not going to be much over a single lap. 8 to 10 hp is not going to do much there. I think on a single qualifying lap where you have your battery charged up anyway, I think you’ll see maybe .1 sec. Where I think will see the biggest gains are over the course of the race. They should be able to use the energy for longer periods during a lap, and also recover much quicker. So hopefully if they qualify fifth, they won’t get passed by three or four other cars during the course of the race and end ninth.

With 800V system can be smaller and thus lighter. Lower current means smaller diameter cables, that's additional weight reduction but also helps with packaging.

BTW, even in commercial applications everyone wants SiC. Whenever any project is being discussed SiC is a must.

I also think that what sounds like a relatively small (~1%) horsepower increase has compound effect on setup. Ie if you’re 25 horsepower down, you have to take off a reasonable amount of wing vs optimal to avoid being a sitting duck on the straight and this is likely part of the cause of Ferrari’s graining issues. 15 horsepower deficit (and these are made up numbers, I have no idea what the deficit is) is possibly more manageable, allowing you to run more downforce.

This doesn’t just help lap time but also helps time over an entire stint. It may be that the difference is not as significant as all that - we need more races and starting nearer the front may give a clearer picture - but it seemed encouraging from Russia.

Third pic there is the 2020 Ferrari PU.
Has this been posted here before?



I swear with all the split turbo engine images, the normal ones look weird
