Red Bull mechanics have been busy ahead of final practice for the Australian Grand Prix after the team opted to change Max Verstappen’s chassis.

    Verstappen was the quickest non-Mercedes driver in Friday practice, the Dutchman finishing third behind Lewis Hamilton and Valtteri Bottas, eight-tenths off the ultimate pace.

    On Saturday, the FIA revealed Red Bull had completed a scrutineering declaration – as part of the rules for this year which involves the team having the freedom to self-scrutineer – which confirmed they had changed the survival cell.

    A Red Bull spokesperson told Formula1.com it was a “precautionary change due to a concern with the fuel cell”.

    Verstappen’s RB15 is expected to be ready for final practice and qualifying later on Saturday.
