Red Bull still managed to get on pole for the Saudi Arabian Grand Prix, with Sergio Perez topping the timesheets after Max Verstappen's driveshaft issue, and Charles Leclerc conceded the defending champions are "on another planet".
Verstappen was stunningly knocked out of Q2 after the mechanical failure forced him to limp back to the pits.
That left the fight for pole in Jeddah wide open but Perez shut the door for Red Bull's rivals, claiming his second career pole at the circuit where he claimed his first last year with a lap of one minute and 28.265 seconds.
Leclerc was second for Ferrari, but his 10-place grid drop for taking on too many control electronics units will see him start 12th, with Aston Martin's Fernando Alonso taking his place on the front row after qualifying third.

While Leclerc, who challenged Verstappen last season before reliability and strategy problems dashed his hopes, was pleased with his performance, he was realistic about the Scuderia's capabilities compared to those of Red Bull.
"It has been a very difficult weekend in terms of pace for us but on my lap I think I put everything into it and it was really on the limit," said Leclerc, who was just 0.155 seconds behind Perez.
"On the other hand, Red Bull are on another planet and we are struggling a little bit, so we need to keep pushing, but that is what we are doing as a team.
"Tomorrow isn't going to be easy. I have a 10-place grid penalty, so we will be starting a little bit further back, but we will focus on the race and hopefully come back to the front as quickly as possible."
Asked about apparent improvements in race pace in Friday's second free practice session, Leclerc replied: "The race pace looked quite good but it's very difficult to compare because in FP2 everyone is running a different programme, but it seemed a little bit better.
"We will see but it is not going to be easy because I think everyone is going to be very close on race pace."
Alonso's mood was in stark contrast to that of Leclerc, the two-time world champion clearly revelling in being a car that can compete at the front again.
"Qualifying was our weak spot in Bahrain but we performed very well [here] so let’s see what we can do. It is amazing," Alonso said.
"We are confident, the gap on the long runs [on Friday] was affected by traffic, so we feel very strong. The strongest point of the car is the long-run pace and how we treat the tyres, so it should be better on Sunday."
George Russell will start third for Mercedes after qualifying fourth, four spots ahead of team-mate Lewis Hamilton.
Russell will have Leclerc's team-mate Carlos Sainz for company on the second row, with Lance Stroll in the other Aston Martin behind them on an intriguing grid.
Verstappen, who has won the last two world titles and tasted victory in the Bahrain season-opener, will start in 15th position.
