Mercedes admit 'issues' after Lewis Hamilton's Texas trouble

He referred to car problems and said Hamilton's exit was "one hundred percent the car" as he was "not even pushing at that stage… and Lewis Hamilton doesn't lose a car on lap five like this."

Wolff also spoke out about the inconsistencies of stewards' decisions that on Sunday included a five-second penalty for George Russell who finished a fine sixth after starting from the pit lane.

Clearly referring to a stewards' decision to give McLaren's Lando Norris a five-second penalty for gaining an advantage when he was forced off track as he passed Red Bull's Max Verstappen, Wolff was enigmatic.

"It's inconsistent," he said. "Yesterday, we've seen a few of those incidents which were exactly the same but weren't penalised - racing for positions actually, real positions and receiving that penalty is just completely odd and bizarre.

"I think we know, but obviously you can't say that on television... some of that decision making at the end. Sometimes, there's correlations between when there is decision-making that is a bit interesting."
