Toto Wolff conceded Mercedes' car is a "nasty piece of work" as Lewis Hamilton 's difficult season continued in Miami.
Hamilton, a multiple world champion, has yet to win a race in the 2023 season. The Englishman will start the Miami Grand Prix down in 13th after a tough qualifying session, behind all three of the drivers currently ahead of him in the drivers' championship.
Sergio Perez, who won last time out in Azerbaijan, claimed pole and has a chance to leapfrog Red Bull team-mate Max Verstappen in the overall standings. For Hamilton and team principal Wolff, though, things have gone from bad to worse.
