Why aren't we using AirShaper to do aerodynamic testing ?

Hey guys, I'm just wondering why none of us have used AirShaper to do testing on our cars ?
Or any CFD for that matter.

When the guy from AirShaper came to the forum, you all just threw...

Ford F150 - 25% drag reduction

Hi everyone,

using a 3D scan of the Ford F150 and a bunch of aerodynamic simulations, we demonstrated how the aerodynamic drag of a Ford F150 can be reduced by 25% - see this link:...
