That indeed makes things different:
I'm guessing the "rear" air vent is mainly there to evacuate some high pressure air from the wheel well and perhaps create a better attached flow on the side flank. I'm guessing (again, haven't done a sim with & without that) the order of magnitude of effect...
We didn't run a back-to-back simulation with & without air curtain, so I don't have info on the real difference. But I would guess it's in the order of magnitude of 1%.
I've attached a screenshot below where you can at least see an indication that the flow through the air curtain...
Oh that one looks bad!
It's too small & slender compared to the size & design language of the car itself, I would say.
Also, if we're honest, you need a lot of aero if you want to have substantial effects on a 2.5 tonne car, so it may need to be bigger :)
We did an automated morphing of the...
I agree @Kingske
Legacy arguments probably come into play.
I did see a video of "Engineering Explained" where he mentioned that Porsche "reserves" some battery capacity for regen situations / future battery capacity loss:
I agree @submatrix , having the car up the "lift" really makes it look very nice!
Tesla does work on aero quite heavily, but indeed, I don't know of any active flaps at the front. They do have air curtains, and we've had the fortune to have a look at a 3D scan (which we then compared to wind...
I agree! In principle, brake discs can be made smaller if you use re-gen braking. But given it's a Porsche, I can imagine they don't want to take chances (a full battery prevents you from braking through re-gen, for example, or things could overheat when doing it too often) and still fit full...
we just released a video on the aerodynamic features on the Porsche Taycan:
I hope you like it!!
All comments welcome :)
In part 2, we'll take it to the streets and compare the results with simulation data!
