Power unit change for Valtteri Bottas!

Mercedes will change Valtteri Bottas' power unit after a problem with the original one was discovered.

At the time of writing, Valtteri Bottas has failed to set a lap time in FP1 and Mercedes have revealed the reason is due to an issue with his engine.

The Finn will not receive a penalty for the change, but is under investigation for entering the pit lane the wrong side of the bollard.

UPDATE: We will do a PU swap with Valtteri as a problem with the current unit has been identified. We are swapping in the other PU already in the pool. This will allow us more time to trace the problem outside the car. #HungarianGP #FP1 pic.twitter.com/qdHXH1xARo
