Lewis Hamilton’s troubled start to the new season took another desperate twist on Saturday after he qualified a lowly 18th for the Chinese Grand Prix.

Hamilton earlier in the day had led the sprint race in Shanghai for eight laps before he had to settle for runner-up after he was overtaken by eventual winner Max Verstappen.

But less than four hours after Hamilton’s drive to second place – a result he described as his “best in a long time” – the 39-year-old was brought crashing back down to earth when he was eliminated in the opening phase of qualifying for Sunday’s main event.

The seven-time world champion locked up at the penultimate corner on his speediest lap, and he finished in the Q1 knockout zone, leaving only RB’s Yuki Tsunoda and Williams’ Logan Sargeant behind him on the grid.

An exasperated Mercedes boss Toto Wolff looked to the heavens after Hamilton’s fate was confirmed.

“Sorry guys,” reported Hamilton, 39, over the radio. He finished eight tenths off the pace and half-a-second behind George Russell in the other Mercedes.

Aside from his strong showing in Saturday’s 19-lap dash to the chequered flag, this has been Hamilton’s worst-ever start to a season.

The British driver, who is leaving Mercedes to join Ferrari next year, failed to finish inside the top six at the opening four rounds of the campaign. And his bleak result in qualifying here leaves him staring at another underwhelming result.

Carlos Sainz, the man who is giving up his seat at Ferrari for Hamilton next year, brought out a red flag in Q2 after he lost control of his Ferrari.

The Spaniard dropped his rear wheels on to the gravel on the exit of the final corner, sending him backwards into the wall on the opposing side of the track.

Sainz broke his front wing but he was able to limp back to the pits.

Lando Norris said it was “all or nothing” as he mastered a rain-hit qualifying to secure pole position for Saturday’s sprint race at the Chinese Grand Prix.

In treacherous conditions in Shanghai, Norris tip-toed his McLaren to top spot, finishing 1.2 seconds clear of Mercedes’ Lewis Hamilton in an all-British front row for Saturday’s 19-lap dash.

For a moment Hamilton, who has endured his worst start ever to a season, looked to have taken a surprise pole when Norris’ best lap was chalked off for exceeding track limits at the final corner.

But the stewards U-turned on their decision after it became evident the 23-year-old had not gained an advantage as he scrambled for grip while gearing up for his pole lap.

Aston Martin’s Fernando Alonso will line up from third for Saturday’s sprint race, one position ahead of Max Verstappen who struggled in the inclement conditions in his all-conquering Red Bull.

“It was wild,” said Norris. “You always know it is going to be in a session like this.

“You only have three laps. The first two I aborted so that last lap was all or nothing. I was nervous because I made a few mistakes, but you have to risk a lot and push and I was quick.

“I got a good final lap in for pole so I am happy. I am sad it is not real qualifying, but it is good enough. It gets your heart going and it is what we wanted.”

On Formula One’s return to China after a five-year absence, rain threatened throughout qualifying and it finally arrived for the decisive Q3 session.

Charles Leclerc was the first to fall foul of the downpour when he lost control of his Ferrari. The Monegasque pirouetted through the gravel before hitting the wall at Turn 2 and breaking the front wing on his Ferrari. He had to settle for seventh.

Verstappen made not one, but two uncharacteristic mistakes – driving off the road in his first attempt at pole, before later running through the sandtrap at the final corner.

Mercedes’ wretched run had appeared set to continue here after George Russell was eliminated in 11th in the dry – but when the rain landed, Hamilton looked at home as he secured his spot on the front row.

“I am so happy,” said the 39-year-old, who failed to finish inside the top six at any of the opening four rounds.

“When I saw the rain coming I was getting excited because in the dry we are not quick enough. I thought I would have a better opportunity and that is when it all came alive.

“Tomorrow depends on the conditions and if it is like that, maybe we will have a chance of being somewhere up there, but if it is dry the Ferraris and Red Bull will come by.”

Earlier, the start of Q2 was delayed by several minutes following a second bizarre track fire of the day.

Practice was red-flagged when a patch of grass next to Turn 7 caught fire. And in qualifying the grass was ablaze again, this time at Turn 5.

Although both fires were quickly extinguished, the incidents – which the FIA believes were caused by sparks flying off the drivers’ cars – will be a concern for the sport’s bosses.

Saturday’s sprint takes place at 11am local time (04:00 BST) ahead of qualifying for Sunday’s main event.
