Toto Wolff plays down the impact of the upgrades that Mercedes have brought for the Miami Grand Prix.

Mercedes have a revised specification of front and rear wings at the Miami GP. The upgrades seem to be working as the Silver Arrows were among the leaders on Friday with George Russell on top of the standings in FP2.

Wolff admits that the upgrades are effective, though that they are not a game-changer.

“I think we brought some parts that function. The lower-drag package generally has been good to us in the past. The track surface seems to be very smooth, so our bouncing problem isn’t articulated like on some of the other tracks and I think we’ve just managed to chip away at lap time,” the Mercedes team principal said.

“And yesterday was good, but we need to be also honest with ourselves: it’s not like we have brought a ground-breaking solution. Probably, the circumstances favored us yesterday. We haven’t seen Max [Verstappen] running properly, so I would express caution at this stage.

“Yes, I think we have more clarity with where we need to go but I would say if we were to put our car in Imola, 10 degrees and rain, the picture would maybe have been a little bit better – but still not good enough.”
