Does downforce increase when it snows?

i think it would negatively impact free airflow as the air is now 'clouded' with particles. also, water. and frozen.
then again, i wouldn't know where to start in properly investigating.

what i can tell though is that looks absolutely fantastic! great picture.

Obviously yes. All those snowflakes hitting the car at high speed push the car down more.

[Moose]

Not sure about when there's actually snow in the air - but when it's cold... yes. Colder air is denser, which means downforce increases.

Anyone know why LM cars keep there wipers in a central position upright.

[Greg Locock]

Snow is denser than air. The snowflakes have to be accelerated along with the air.as the car passes. So yes, they will affect the forces on the car. Now you job is to work out the change in the density. WAG, hardly anything.

less drag

[Andres125sx]

Relatively, yes (or probably ), in absolute numbers, no, since snow implies wet and very cold tarmac so cornering speed is greatly decreased, thus total DF decreases too

Could have them hidden several road cars have them hidden when not in use

Road cars tend to have a pretty huge cavity under the trailing edge of the bonnet allowing them to 'hide' the wipers.

On LMP1 cars, the windscreen is perfectly adjacent to the top of the tub, so nowhere to hide the wipers. They do sometimes use a little cover for the base of the wiper (example is my model):

If/when snow accretes into ice, the aerodynamic profile is generally deleteriously affected.
