When we did the original Volt we were at 0.284. We were good with that because it allowed us to round down and advertise that it was 0.28.
The only problem was when we starting auditing the first production vehicles they were checking at .285, which would require us to round up to 0.29. We launched a very in depth investigation and were re-checking everything aero related (which includes every little skeg and bump, whether on the front or the rear of the car).
As it turns out those first production cars were building 5mm high. We retrimmed them out, dropped them the 5mm and got our 1 count back.
