Would high rake be a disadvantage on the 2021 smaller floors because of the sealing of the floor?
The high rake concept will be a disadvantage next year due to the smaller floor but, on top of that, because of the abolition of the slots in front of the rear tires.
They are fundamental to avoid dirty air going under the car damaging the aerodynamics of the diffuser, so next year diffusers will be way less efficient.
Why is the fia constantly making rules to make Mercedes faster anyways
trade off, higher rake too will be effected by the new rules because the floor is steeper so pressure build up towards the rear, on top of the floor is greater and that will move air around the new floors cut out towards underneath. low rake longer floor which has more surface area for ground effect, with the new floor rule, will allow negative pressure underneath the car to recover that negative pressure reducing ground effect unless the bargeboards and the rest of the aero package can keep the recovery at a minimum.
there is a huge aerodynamic advantage the longer chassis allows compared to a short chassis. vortex can run longer along the body to be more effective while certain criteria, say, if the aerodynamicist wants to drag as much air downwards as possible towards the diffuser and rear wing, the longer bodied car has more area to do this
one reason maybe that red bull racing are running a short chassis high rake is that, as the rear suspension compresses, the rate of air approach angle ratio change is greater than those running long chassis and maybe this is also why the mercedes-amg dont really bother running high rake because the angle will only change marginally while the suspension geometry is compromised further when running high rake angles
