Wonder if F1 teams can build desktop tunnels to test 15% models and make it accurate

I wonder if FIA would count that in terms of ATR.

In the new ground-effect era, where the cars run closer to the ground, the interaction between the car floor and track surface has become a key performance differentiator.

Last summer Ferrari shut down its F1 wind tunnel to install a new ‘rubberised’ rolling road which, while less durable than the conventional steel belt, more accurately reflects the texture of a track surface.

Teams have historically used smooth surfaces because it meant the 60% test tyres that Pirelli gave them lasted longer.

Quiet sure they can wheel them out of the design office if an FIA inspector comes around.

They probably figured they can do this...........

you're not allowed to modify the supply wind tunnel tyres

A very insightful video what's actually happening and what a WT facility looks inside:


Amazing content from Williams!

Are the parts of the 60% models nowdays full 3d printed or not? I would think it is the cheapest way to produce them.

Material selection is based on mechanical requirements and lifing (frequency and amplitude of vibrations and how long it's expected to remain on the model) of a part.

There’s a rolling road. It’s just hard to see in that angle.
