Mercedes forced to lift the car after suffering from bouncing

Mercedes drivers Lewis Hamilton and George Russell have revealed that the bumpy nature of the resurfaced Autodromo Jose Carlos Pace has been hindering their car W15's performance in sprint qualifying.

Lewis Hamilton was struggling with the bumpy track in the sole practice session at the Sao Paulo Grand Prix, but it was not clear what he would be able to achieve, given the fact that he only used the medium tyres in FP1.

Although Hamilton looked relatively strong in the opening segment of sprint qualifying, he was unable to make it to SQ3. The seven-time world champion, who will drive Ayrton Senna's 1990 McLaren MP4/5B after qualifying for the Brazilian Grand Prix on Saturday, has revealed that Mercedes were forced to lift the car between the practice and the sprint qualifying session to improve the ride on the bumpy surface.

"It has been a difficult day for me – notwithstanding the incredible support from the amazing fans here in Brazil. I think the ride on the bumpy surface has been pretty bad for everyone, and it made FP1 very challenging inside the cockpit.

"We lifted the car during the break and improved the situation, but the pace simply wasn’t there when it came to the timed laps – the balance is on a knife edge, and the car just so tricky to drive and I couldn’t attack any of the corners as I wanted to.

"I hope we can move forward from P11 during the Sprint and keep working to figure out how to find the sweet spot of the balance in qualifying tomorrow afternoon."

His team-mate George Russell did make the top 10 shootout, but wound up sixth. However, he was unable to challenge for top places, with Ferrari, McLaren and the Red Bull of Max Verstappen proving too much of an ask for the British driver.

"That was a challenging session as the track cooled through Sprint Qualifying. Finishing P6 is reflective of where we are right now, at the back of the front pack of teams, and with a pace delta to the next group behind us.

"I enjoy the challenge of Sprint weekends, getting straight into the action, and of course today has also brought the slightly unexpected challenge of a very bumpy track – which obviously is the same for everyone. For tomorrow, I will be looking to move forward and using the Sprint to work out where we can improve the car for qualifying and the Grand Prix on Sunday."

Commenting on a difficult sprint qualifying session for Mercedes, trackside engineering director Andrew Shovlin insisted that the W15's performance is heavly influenced by the bumpy surface.

"It has been a challenging day for us in Interlagos. Running in very warm conditions in FP1, it quickly became clear that the resurfaced track was as bumpy as ever, and that this would provide us with a set-up challenge for the weekend.

"Both drivers completed decent long runs, and we made relatively small changes going into Sprint Qualifying. Once we began running, it became clear that neither George nor Lewis were completely happy with the balance, suffering with snaps at the rear. This cost Lewis confidence and lap time, and saw him knocked out of SQ2 by less than 0.1s.

"George was able to reach SQ3, eventually taking P6 but with a substantial gap to Piastri on pole. The Sprint tomorrow is going to be useful to learn about the long run balance ahead of qualifying in the afternoon. It’s normally a good circuit for overtaking so if we have pace, there’s every opportunity for both drivers to move forward."
