Red Bull's Max Verstappen said his RB22 Formula 1 car is "completely undrivable," after qualifying eighth for Sunday's Chinese Grand Prix and a torrid sprint race earlier in the day.
"We changed a lot on the car, and it makes zero difference," the four-time world champion told reporters after setting a fastest lap that was around one second slower than pole-sitter Kimi Antonelli, with the two Mercedes cars securing a front row lockout as George Russell qualified second following car trouble.
The Dutchman added: "The whole weekend we've been off, the car is completely undriveable. Every lap is like survival."
The Red Bull Racing driver sunk to as low as 14th place after having qualified eighth in Saturday's earlier
19-lap sprint race around the Shanghai International Circuit, finally finishing in 9th and behind sister team Racing Bulls' Liam Lawson.
"It's incredibly tough to drive. There's no balance, I cannot lean on the car, every lap is a fight," the 71-times grand prix winner told Sky Sports F1, having come into the weekend hoping to make more of an impact after making his way from the back of the grid to finish sixth at the
previous race in Australia.
This is the first season Red Bull have run their own engine, having partnered with Ford, which ended a very successful six-year streak with Honda.
Verstappen said the new power unit was partly to blame, but added that the poor performance was down to a multitude of factors.
"From lap one of these new regulations, I have not enjoyed this car for sure," he added. "It's not going to be a fun race."
Verstappen has been critical of the new-for-2026 F1 cars so far and his recent struggles will not be helping change his mind about them.
