Yes, technically that would certainly be possible.
The challenge is that it requires very detailed simulations to capture these effects. For us, that means our 2.500 USD Advanced simulation with 50-100 million cells. We can run some cases on the house for media purposes, but this would be...
Supercool to see the data of the tests they performed.
Some comments, many of which have been mentioned before:
- The goal of an "air breather" as BMW and perhaps others call it is indeed to evacuate some of the high pressure air in the wheel wells (the wheels rotate and spin the air, building...
Oh my bad, misunderstood your question!
The answer is the same in terms of 3D model:
we'd need one with open & closed vents.
On top of that, the internal modelling of the cooler is quite complex. Often, this is done using a "porous" block, which features a uniform flow resistance (rather than...
Hi Jim,
no, we don't have 3D models with the vents both open and closed.
I would guess an open vent helps to evacuate some of the high pressure from inside the wheel well and feed it into the turbulent area behind the wheel. And perhaps the grid/maze/... structure inside such vent can help...
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...
Hi @Kingske
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...
Hi everyone,
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!
