This is very interesting.
This is a Lotus F1 car with a Mercedes turbo compound
engine. The unique  S shaped composite wing support
strut is mounted on the turbine housing for some strange
reason. Composite material loses stiffness as it heats
up. This means the angle of attack and the wing drag
will be reduced quite a bit as the strut deflects  downward
due to  wing drag and wing down force. If measured
at room temperature the deflection will be much less.

This will increase the top speed of the car
compared to other cars with more ridgedly
mounted wings.

I used this idea in the late 1960's and early 1970's on my
suspension mounted wings except for the temperature effect.
I did it with rubber bushing in the strut fittings attached
to the hub carrier.
