Max Verstappen will use another new gearbox ahead of qualifying day for the Formula 1 Miami Grand Prix, with the Red Bull driver using a higher-than-average number for the season so far.
The reigning World Champion will use his third new gearbox of the season in Miami, meaning he will be permitted just one new gearbox over the remainder of the 23-race season.
The Red Bull driver took his second gearbox of the season just three races ago in Saudi Arabia in what was already considered an early change.
The team will still be permitted to use the older gearboxes as part of Verstappen's 'pool' of parts, but it is not known how usable the remaining gearboxes are.
Red Bull have also not yet detailed any issues with the gearbox that was run on Friday.
Should Verstappen use more than four new gearboxes over the course of the season, he will be given grid penalties.
Carlos Sainz has also taken a new gearbox for the weekend, but the Ferrari driver will only be using his second of the season.
There were also new Control Electronics (CE) and Energy Stores (ES) for McLaren's Lando Norris, Williams' Alex Albon and Aston Martin's Lance Stroll, with no driver receiving any penalty.
