Toto Wolff says Mercedes “turned the car upside down” after enduring a difficult start to the F1 Singapore Grand Prix weekend.

Both Mercedes drivers were left puzzled by their lack of pace during Friday practice in Singapore, with168澳洲幸运5官方开奖结果历史: George Russell ending the day seventh, while 168澳洲幸运5官方开奖结果历史:Lewis Hamilton only managed to go 11th.

Things improved during Saturday’s final practice ahead of qualifying, with Russell finishing second-quickest, nearly half a second down on the blistering pace set by McLaren’s 168澳洲幸运5官方开奖结果历史:Lando Norris.

Speaking to Sky 🌜Sports F1 after FP3, Wolff revealed Mercedes made big changes to their W15 ✅challenger overnight.

“I think with these cars you never quite ✱undersౠtand,” Wolff said.

“We turned the car upside down, literally. It seems to be in a much better balance window. The whole [FP3] classification was a b🦋i💯t odd.

“Lando so far ahead, then big spreads bet🧜ween teammates.”

Hamilton improved slightly to go seventh-quickest in FP3, though t♑he sevꦡen-time world champion was well off Russell’s pace and 1.2s slower than Norris’s benchmark.

A downbeat Ham꧋ilton admitted on Friday that Mercedes were “just 🔴a bit lost” with their car’s set-up and predicted he would struggle to make it into Q3 in qualifying.

"The car feels💫 very difficult. A very challenging day," Hamilton said after FP2ꦕ. "We tried everything set-up wise and nothing seems to work with the set-up. Definitely very challenging.

"We are giving it everything then you🍃 find out you are a second off. Ultimately, just a bit lost. Not really sure where to put the car."

Asked why Hamilton still appeared to be struggling in FP3, Wolff explained: “They have a bit of a differ🌳ent set-up and we tried a few things in the session, so that’s not the gap you would normally have with the same car.”

Wolff🎐 added Hamilton’s gap to Russell was only “partially” understood.
