Michael Andretti says he is still hoping to be on the grid in 2025, but still waiting for conversations with F1/FOM to even begin.
You're viewing a single thread.
Is GM not yet involved? Why would they use Toyota's wind tunnel and not one of GM's?
There are rules regarding wind tunnels. McLaren already had a wind tunnel, but used this same Toyota tunnel until this year.
There are rules regarding wind tunnels.
There aren't for non-participants. You can make an 2023 F1 car model and test it in your private wind tunnel for how long you like.
If you're looking to build a model to build upon for an actual car. Then it makes sense to follow the rules.
Then it makes sense to follow the rules.
What amount is their wind tunnel and CFD allowance then? 🙄
Hint: The FIA has not allocated wind tunnel and CFD time to Andretti because they aren't competing.
Don't know what you're deliberately being obtuse. The implications of Andretti building a model to F1 spec is pretty clear.

The car specs aren't an answer to why not using a GM wind tunnel. https://www.fia.com/sites/default/files/fia_2023_formula_1_technical_regulations_-_issue_1_-_2022-06-29.pdf does not have any chapter of wind tunnel legality.
Again you're being deliberately obtuse.
If there are rules regarding wind tunnels and you want to show you can build an F1 car to spec, why use a wind tunnel that doesn't follow those rules.
There is no way you can see Andretti build a model to F1 spec and test it in a wind tunnel used by F1 teams. And not understand the significance of that.
If there are rules regarding wind tunnels
I've linked to the PDF of the rules. There are no wind tunnel rules.
That's because those rules are in the sporting regulations. Appendix 7
The following restrictions apply during RWTT: a. Only wind tunnels that use air at atmospheric pressure as the test fluid are permitted. Other than rotations of the RATG and model or ground plane about the yaw axis, designs which attempt to create curved flow conditions relative to the RATG are not permitted. For closed section wind tunnels adaption of vertical walls and the ceiling to improve air flow uniformity is permitted. Particle image velocimetry systems where the wind tunnel air transports a flow visualisation medium are permitted. b. No RWTT may be carried out using a scale model and RATG which is greater than 60% of full size neither may it be carried out at a wind tunnel air speed exceeding 50m/s measured relative to the scale model and RATG. Furthermore, during restricted wind tunnel testing the magnitude of the rate of change of the wind tunnel air speed measured relative to the scale model and RATG must be less than 4.5m/s². The rate of change of the wind tunnel air speed will be defined as the derivative of wind tunnel air speed and smoothed using a moving average filter, centred on each sample, of period 0.5 seconds during each wind tunnel air speed ramp up and ramp down phase. These phases are defined as the periods when the wind tunnel air speed is varying between 15m/s and 95% of the maximum wind tunnel air speed during a run.
There's quite a bit about it in there. You should read it some times. https://www.fia.com/regulation/category/110
