Mercedes will run Frederik Vesti in Friday’s FP1 at Mexico City, with George Russell stepping aside. The move satisfies the FIA rookie requirement ahead of the October 26 Grand Prix.
Each car must surrender one FP1 to a rookie across the season. Kimi Antonelli completed the sister car’s allocation earlier, leaving Russell’s side due to run a newcomer.
For Vesti, this is a fourth FP1 in three seasons. He last sampled the W16 in Bahrain, and has since focused on simulator correlation and physical preparation for high-altitude demands.

Mercedes accepts the usual FP1 trade-offs. Early long-run work compresses, but the team values fresh feedback and correlation data more than the marginal setup time sacrificed.
The FIA regulation mandates two rookie FP1 outings per team, one per chassis, for drivers with two or fewer race starts. Mercedes remains on schedule with this Mexico commitment.
Vesti’s year includes consecutive IMSA victories at Indianapolis and Petit Le Mans. That endurance mileage underpins his sharpness and complements targeted neck training for Mexico City’s G-loads.
Expect a conservative run plan: baseline aero, tyre data gathering, and correlation checks, before handing the car back for FP2. Russell refocuses on qualifying and race preparation thereafter.
Any FP1 concession is minor, but significant margins are scarce against Red Bull and McLaren. Clean execution will determine whether Mercedes extracts net gain from the rookie allocation.
The Autódromo’s altitude skews cooling, turbo efficiency, and downforce levels. Mercedes targets a tidy baseline to stabilise tyre temperatures and manage brake and energy systems across long runs.
Vesti’s outing fits Mercedes’ longer-term development strategy while maintaining race-weekend momentum. The immediate objective is clean mileage; the broader aim is improved simulator fidelity into Sunday.
