Felipe Massa tops the timesheets at the end of the first day of the final test, blitzing his rivals on the supersoft tyre for Williams.
It was also an encouraging day for Red Bull, who finally showed what pace they could have in store for us in 2017, while Ferrari continue to impress on the long and short runs.
Mercedes finished their day with their drivers in a somewhat disappointing fourth and fifth place, but of course, we never quite know what teams are holding back here.
Williams set the pace, Red Bull start to show their hand, while McLaren run into yet more engine problems.
