Mclaren have been using Toyota's wind tunnel in Cologne for years - I'm not sure how that stacks up these days compared to the other teams. The problem with their own tunnel is that it is just too small for a 60% model, or anything close
Surely it might be that their wind tunnel is too big? because it would be used for full sized road cars?
The problem with the wind tunnel is not because of the physical size of the race car, it has more to do with the how the air is displaced / moved by the aero surfaces.
When the cars changed from an inboard aero concept to an outboard aero concept (in order to manage the front tire wake), the restrictions due to the size of the tunnel were apparent… The air been pushed outwards by the front wings would not have enough room in McLaren’s tunnel and therefore they had to move to the Toyota Tunnel in Cologne, which is effectively larger (and at the time, probably more up to date in terms of technology)
