George Russell to serve additional grid penalty for engine change

Mercedes driver George Russell will start Sunday's Singapore Grand Prix from the back of the grid due to a new engine, exceeding his seasonal limit. Russell confirmed he expects a further penalty later this year once a planned engine upgrade is introduced to complete the remaining seven races.

In Singapore, Russell will revert to an older car specification used in Azerbaijan to help the team evaluate recent aerodynamic upgrades. Mercedes is splitting car specifications between Russell and teammate Kimi Antonelli to determine if performance issues stem from track characteristics or the upgrade package itself.
