While some 8 teams have chose not to use the wide window 2 have gone for the wide window. I guess it is easier to design a floor with a narrow window rather than for a wider window.venkyhere wrote: ↑28 Jun 2026, 08:41
Thank you.
But how narrow is 'floor optimal window' in this era ?
The 'floor-downforce' is now coming from high suction force spread over a large rectangular area, rather than super-high-extreme suction force coming from a pair of venturi tunnels of the GE era (relative proportion of the two factors in the force x area equation). So the 'window of operation' surely has to be much wider compared to GE era. Which in turn means the need for tremendous anti-dive / anti-squat suspension geometry is much lesser, I reckon ; and in exchange providing a much better cornering feel to the driver & much better kerb riding ability, by having a conventional suspension geometry and softer suspension stiffness w.r.t the GE cars.
But that is 'vanilla/conventional' thinking from me. Obviously 3 out of the 4 teams have seen something more nuanced and have stuck to the aggressive anti-dive/anti-squat.
I should have framed my question better - what makes 'almost-nil' longitudinal movement of the floor in high speed corners so critical in 2026, when it was fine to have movement in 2021 ? Am I even asking the right question ? Does anti-dive geometry still being present, have anything to do with high speed cornering ?
It is early days, the front wing getting closer to the road at low speeds during braking has not been exploited yet by RB.
When the font wing gets too powerful with relative to the speed of the car, tipping forward, there is going to be too much front end for a high speed corner. This will force instability at the rear and driver will have to work harder through the corner.
In comparison the anti-dive is going to hold the wing at more optimal place and not allowing the front to get too powerful.
