Lance Stroll set the initial pace for Aston Martin in the sole practice session held as the Chinese Grand Prix made its long-awaited return to the Formula 1 calendar.
The Canadian posted a late flier on the Soft compound to head the times with a best lap of 1:36.302s, three-tenths clear of McLaren’s Oscar Piastri in second place.
With a re-laid track surface to bed in at a venue the sport hasn’t visited in five years, the drivers emerged from the pit lane to commence the single 60-minute practice.
However, the teams’ run programmes were disrupted 15 minutes in when a small patch of grass caught fire on the inside of Turn 7 and resulted in a red flag stoppage.
But the setback would prove minor as the session resumed within five minutes, with drama on the restart as traffic in the final sector saw Lewis Hamilton obstructed.
The Mercedes driver had maintained track position over Nico Hulkenberg’s Haas at Turn 14, but he had to take avoiding action into the pits to avoid Piastri’s McLaren.
Hamilton was noted for failing to follow the race director’s notes regarding the white lines on the entrance to the pit lane as he locked up heading into the final corner.
There were no such fleeting issues for Ferrari, with Leclerc heading Sainz at the top of the timesheets as the Italian marque held the nascent advantage over Red Bull.
However, the two Red Bull drivers had been equipped with Mediums and displaced the Ferraris in the closing stages as Verstappen powered to the front of the order.
The Dutchman wound up almost five-tenths clear of team-mate Sergio Perez, who sustained a lock-up which prevented him from getting closer to the ultimate pace.
That enabled Kevin Magnussen to split the two Red Bulls in his Haas, prior to Piastri edging his McLaren MCL38 above Verstappen with a time 0.031 seconds faster.
Piastri’s McLaren team-mate Lando Norris had been on course to usurp that time as he was four-tenths up through the opening two sectors but abandoned that lap.
Stroll would emerge at the end to set the ultimate pace to beat Piastri and the two Red Bulls, with Hulkenberg slotting his Haas car ahead of his team-mate into fifth.
Esteban Ocon is running the upgraded Alpine A524 this weekend and made a positive start to the weekend in seventh, with Williams’ Alex Albon a promising eighth.
Daniel Ricciardo was ninth in the lead RB ahead of the two Saubers, with Valtteri Bottas pipping team-mate and home favourite Zhou Guanyu to a place in the top 10.
Yuki Tsunoda trailed three places behind Ricciardo in the sister VCARB 01 car, while the Ferrari duo dropped through the order with those late runs to 13th and 14th.
Logan Sargeant had begun his debut outing at the Shanghai International Circuit as high as second at one stage, but he also slipped down to be classified 15th overall.
Norris was rooted to the bottom five with his ditched run, with the two Mercedes drivers also setting their best laps on the Hard rubber and languishing at the bottom.
Fernando Alonso was in the same predicament in the second Aston Martin and resided 2.6s behind his team-mate at the top, with Pierre Gasly 20th and last for Alpine.
