Mercedes' Valtteri Bottas finished seventh in the Russian GP, ​​but due to changes in the power unit, the Finnish driver will drop to the starting box 17, Autosport reports on Sunday.

Modifications were made to the engine elements of the Bottas Mercedes during the night.

Bottas ’starting grid penalty can be considered a tactical game move from Mercedes.

Bottas teammate Lewis Hamilton is at the forefront of the World Series in a tough battle with Red Bull’s Max Verstappen.

Verstappen received a three-point penalty from the Italian GP Kolari.

An entirely new power source was also replaced for his car, so the Dutchman fell into the last starting box.

Now, also starting from the back, Bottas will be able to slow down Verstappen, who is leaving behind, and thus improve Hamilton's chances.

Hamilton starts from the fourth starting box.

A new power unit in Italy was replaced for Bottas' car.

The Finn, who started from the back team at the time, rose to third place in the race.

The Sochi GP will start today, Sunday at 3 p.m.
