Today was a stop-start but ultimately productive day of running for McLaren-Honda. Despite losing out on mileage over the course of the test due to reliability issues, the team pushed ahead with its scheduled test programme: this morning with a focus on aeromapping, and this afternoon on handling and set-up changes.
The nature of the run plan dictated short runs punctuated with longer spells of set-up changes. A scheduled ESS pack and floor change meant lunch break would be longer than usual, however, while stripping down the car, the team noticed a small water leak, which was also fixed at the same time.
The team then took the opportunity to undertake a more thorough check of the car, its set-up and its systems, to ensure any running in the afternoon could be as productive as possible, but this meant the car remained in the garage for longer than originally planned.
Fernando re-joined the track at approximately 16:00, and despite only clocking up a total of 46 laps, the team gathered a lot of useful data on car and PU behaviour in preparation for Melbourne.
