After yesterday’s disappointing start to the final pre-season test, today was our most productive and promising day of the winter.
The team did a fantastic job to replace the power-unit ahead of today’s session, with the team ready to start when the track opened at 0900. The morning was spent carrying out front-wing work and corresponding set-up changes. In the afternoon, the team switched to a long-run programme, evaluating mechanical balance while also carrying out a number of pitstop rehearsals with the race crew.
Shortly before the end of the day, Jenson stopped out on track with an unspecified electrical issue, but had already completed 101 laps – comfortably our longest daily mileage this year.
The lack of running so far this year means we’re still playing catch-up with our planned development programme, but a day like today certainly helps us to make up ground at a more desirable pace.
“We’ve still got a lot of work still do to, but we had a good day today. It’s never easy when you’ve missed out on so much testing, but we’re making good progress, and we got lots of really useful information today.
“We know we’re not the quickest guys out there, but you’ll certainly see a lot of improvement by the time we get to Australia.”
