wind tunnel to how it performs on the track. The car has sensors allocated to measuring aerodynamic loads as well as the cars ride-height, yaw, roll, steering angle, wind direction and so forth. We have transducers to measure pressure on the various aerodynamic surfaces of the car to see if any of them are misbehaving or behaving differently to their cousins on the wind tunnel model. This allows you to build up a detailed picture of whether the car is performing the same on track as it does in the wind tunnel.
