In response to Valtteri Bottas retirement from the Eifel Grand Prix, Mercedes decided to change the control electronics on the engine of both cars.

Bottas retired from the Eifel Grand Prix after experiencing a loss of power. At first it was suspected to be an MGU-H problem, but it was later revealed the issue was electrical.

In response Mercedes decided to install new control electronics on the power unit of both cars.

“Valtteri’s failure in Germany was located to a failed electrical component in the control electronics,” said a Mercedes spokesperson on Thursday evening.

“Both he and Lewis will take new modules this weekend, and we have made calibration changes too in order to avoid a repeat.

“It’s the second module for both drivers, so within the permitted allocation.”

This change won’t trigger any grid penalties as it is only the second control electronics component used by both Hamilton and Bottas in 2020.
