Mercedes team principal Toto Wolff admitted being frustrated after trying many things during FP1 and FP2 but still lacking performance.
During the first two practice sessions, it was visible that both Lewis Hamilton and George Russell were struggling to drive the W15. The balance of the car was all over the place and, especially in fast corners, the car was very unstable.
Wolff said that Mercedes experimented with different things, but still hasn’t managed to unlock more performance.
“Well, we’ve achieved experiment, but we haven’t unlocked performance.
“I think in the second session, we’ve gone through a quite dramatic setup change on Lewis, and that has massively backfired, but this is why we’re having those sessions.
“On the other side [George Russell] it was a bit better, but we are lacking performance. On a single lap, if he finishes that lap we’re a bit better, but overall, it wasn’t a good thing.”
Wolff also admitted that he is frustrated, but everybody on the team will “keep trying” as he believes the W15 can be a competitive car.
“If I said that I’m not frustrated, it would not be true.
“Certainly, we are [frustrated] because we’re trying so much in all directions, but we don’t seem to have found that silver bullet that helps get us in the right direction.
“We’ve got to keep trying. We’ve seen performance in this car before. I just don’t want to go back and say we’re just not good in these regulations because we have everything we need in order to get on top of that, and we will.”
