Today was a challenging but ultimately productive day on track for the first outing of the second and final pre-season test.
Stoffel took to the track shortly after 09:00, and the team worked progressively through its test programme, which featured more aero correlation, tyre testing and balance and handling evaluations.
Shortly after midday, Honda detected an electrical anomaly in the power unit, and, in order to investigate further, elected to undertake a complete PU change.
The team worked extremely efficiently to get the car back up and running – the engine change taking less than four hours – allowing Stoffel to return to the track shortly before 16:00.
In the afternoon session, the team completed more useful mileage, conducting aero tests and simulation of the type of running expected in Melbourne. Stoffel completed 80 laps by the time the chequered flag fell at 18:00.
