After the push start in our first race of the day we have lost the second controller. The symptoms for both controller failures are identical, blown MOSFETs but the root cause is unknown as the electric drive system has been fully tested in the wind tunnel.
We suspect shoot through as a result of some noise/crosstalk on the gate drivers but there is little time to try to find this.
The car is sadly wheeled off the track and back into the hanger for an attempt at a speedy repair.
