Is ride height in pCars affected by how much fuel is in the tank ?

Yes

It does ?

AFAIK it does affect ride height and weight transfer.

Not sure about that but I'm pretty sure downforce does.

It does, it affects the weight and weight distribution of the car, often quite significantly. Very often in long races I have struggled a bit with finding a good balance between behavior with a full and an empty tank. Some cars that have an unfortunate location for the fuel tank can be real bastards with a full one.

EDIT: Though to clarify, how much it affects the ride height depends massively on the suspension stiffness, the size and location of the fuel tank, for obvious reasons.

To add to the above, even the fuel movement in the tank is dynamically calculated:


We do yes. It's sounding a bit like a heavy fuel tank. The 'slosh' movement of the fuel will dynamically change the centre of gravity.

Also, stiffen your front tyre pressures/arb and reduce front wing/increase rear.

It's only after taking into account the difference of weight distribution and ride height that a full and near empty tank gives, was I able cut my qualifying times down quite a bit.

What! I didn't even know this, such level of simulation, I am amazed this game actually runs on a console with the amount of stuff that is being simulated in real time and yet people are complaining about frame drops and occasional crashes.I am surprised that my PS4 hasn't burst into flames with the amount of calculations going on in that black box!

All I can say is 10/10 for attention to detail, need to factor this in for future reference :)

I like to practice with a full tank and run the entire or nearly entire session trying to better my lap times as the tires wear. When qualifying comes around with a scant tank and fresh boots, BAM extra tenths everywhere and I feel like a superman. I love it.

It s a pitty that the whole parameters taken into account in the model are not detailled somewhere...

Thanks for the link.
But I still haven t found what I m looking for...
