If it was indeed a PP thing - surely the McL design would reflect as much?Advino116 wrote:They are moving from an upwash design to an outwash design. I wouldn't be surprised if the cascades change to a Merc style soon. To me the change makes a lot of sense. An upwash design is fine back then when the front wings were the full width of the tyres, but since reduction in width last year, the flow off the end of the wing should see much higher blockage from the front tyres, which makes an outwash design a more logical design choice for me.
If you watched Scarbs latest video where he talks about Merc's newest front wing, he mentions the long lead times to design and make one, making me think this change wasn't a recent decision. It might be they revaluated their front wing philosophy after PP left and realised maybe Vettel's struggles with the car is partially contributed by the rear end ingesting dirty air off the front wheel wake which is insufficiently controlled by an upwash design. Else, I don't see a reason why they would totally switch philosophies if the upwash design is sufficient.
