Formula 1 world championship leader Max Verstappen (Red Bull) will start the Russian Grand Prix from the back of the grid on Sunday in Sochi due to an engine change.
Verstappen, who is five points ahead of Lewis Hamilton (Mercedes) in the drivers' standings, was already penalized three places on the grid for causing a collision with his rival in the previous round.
The number of changes to the different elements of the single-seater powertrain is limited each season and any change beyond a certain number is automatically penalized.
Monegasque Charles Leclerc (Ferrari) is subject to the same penalty.
In Sochi, Mercedes has been unbeaten since the first GP in 2014: Hamilton has won four times, leaving the other three victories to his teammates Nico Rosberg (2016) then Valtteri Bottas (2017 and 2020).
