Scuderia Ferrari SF90

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

I expect Ferrari poles but I'm not sure about race wins. Their race pace has been very poor compared to Mercedes and Red Bull.
It’s true that they’ve generally had worse race pace, but also that when on pole they’ve had the opportunity to win the race - Bahrain, Canada and Austria could all have been wins with optimal execution (e.g. respectively: reliability, errors, longer first stint on mediums).

But I do think it’s clear that the Ferrari engine modes used in quali are not there in the race - so wondering how much of this new engine is aimed at that. The wording of ‘better management of combustion’ could mean a lot of things, and the article speaks to reliability which also could mean running higher modes for longer. We’ll see, I guess.

One thing is power. Another is power deliverance. Maybe it is not as drivable as Mb and Honda....

Ferrari had issues with fuel consumption they are focusing there atm.

Fuel economy is the thing to aim for once you've got the power sorted. Being able to make big figures for a few qualifying laps doesn't help if you can't make those figures in the race without running out of fuel.

Fuel efficient ICE helps with downforce as well. More drag leads to higher fuel consumption.

I don't think this is necessarily true in a formula1 race. It would be true at a constant speed, but the f1 cars aren't travelling at a constant speed. They basically travel as fast as they can at every given moment. On the straight, this is when when available power=drag. A draggier car with more downforce can go round the corners faster, so the less draggy car has to syphon off more of that kinetic energy to get round the corner, since harvest/deploy isn't 100% efficient it means the draggier car is actually more fuel efficient around a lap assuming the approaches equate to the same overall lap time.

I tend to agree with your view.

My way of looking at it is that the most fuel efficient mode would be to travel constantly at the lap average speed. Every time you go below this speed you waste fuel accelerating to return to the average speed, the further you go above the average speed the more fuel you use pushing the air out of the way b

Of course the reality is a little more complex.

Yes, I know, F1 is on its mid term break, but that does not mean that threads should then go off-topic. Please have a look at the thread title before posting, and try to stay on topic
