A “fired-up” Max Verstappen sent a warning to the rest of the grid that Red Bull are back on form as he set a searing pace to top the first two practice sessions at the Japanese Grand Prix.

Verstappen’s record 10-race winning run and Red Bull’s unbeaten season came to a shuddering halt last weekend in Singapore, where the team admitted they did not understand their struggles with the car’s set-up around the street circuit.

The 25-year-old was confident of a return to form around the high-speed corner track at Suzuka, where Lewis Hamilton predicted the Red Bull would be “phenomenal”, but all eyes were on the Dutchman who is closing in on a hat-trick of world titles.

His response to the struggles of Singapore was immediate and emphatic, finishing 0.626 seconds clear of Ferrari’s Singapore-winner Carlos Sainz in P1 before beating Charles Leclerc by 0.320sec in P2.

Red Bull team principal Christian Horner said: “He dealt with (Singapore) very maturely.

“It was a difficult weekend but he raced very hard. It was what it was. He knew at some point we were going to get beaten and he dealt with the situation well.

“He has certainly come here pretty fired up as you could see from his outlap in P1 today.

“Max knew it was always going to come to an end at some point. That 10th victory meant a lot to him and certainly to the team so I’m glad Singapore wasn’t the 10th in that succession of races. I think he has just shown great leadership and great maturity.”

The second session was red-flagged with a little over two minutes remaining when Pierre Gasly crashed heavily into the barriers at Degner Two, bringing a premature end to the session.

McLaren had been tipped to be the closest challengers to Red Bull and Verstappen this weekend, with Mercedes’ George Russell even suggesting the British team could be favourites.

Lando Norris showed strong pace to finish the day third, albeit 0.464sec off the pace, while Oscar Piastri, who signed a contract extension earlier this week, claimed eighth in the second McLaren.

Red Bull will almost certainly clinch the Constructors’ Championship this weekend at the home race for their engine supplier Honda.

But Sergio Perez was over a second off the pace of his team-mate, finishing 11th in P1 and ninth in P2.

Fernando Alonso claimed sixth for Aston Martin ahead of the Williams of Alex Albon.

Mercedes pair Russell and Hamilton struggled in the opening session, finishing a lowly 13th and 16th respectively, with chief race engineer Andrew Shovlin admitting the team had work to do on the car setup.

Russell claimed fifth in P2 but Hamilton was only 14th, with the seven-time world champion a huge 1.141sec adrift off the pace.

Max Verstappen appears set to return to form at the Japanese Grand Prix after posting a blistering time in the opening practice session.

Verstappen’s record 10-race winning run and Red Bull’s unbeaten season came to a shuddering halt last weekend in Singapore, where the team admitted they did not understand their struggles with the car’s set-up around the street circuit.

Lewis Hamilton warned on Thursday the Red Bull car would be “phenomenal” around the high-speed corner circuit at Suzuka and, while practice times must always be treated with caution, it appears the runaway championship leader could dominate again this weekend.

Verstappen, who is closing in on a hat-trick of world titles, was the first car out on track and it took the Dutchman just a handful of laps to set the fastest time in every sector.

He finished the opening running 0.626 seconds clear of Ferrari’s Carlos Sainz, who clinched victory in Singapore.

McLaren had been tipped to be the closest challengers to Red Bull this weekend with George Russell even suggesting they could be favourites.

Lando Norris delivered an impressive final lap to clinch third for the British team, ahead of the second Ferrari of Charles Leclerc and home favourite Yuki Tsunoda in the AlphaTauri.

Oscar Piastri, who extended his McLaren contract this week, claimed seventh just behind the Aston Martin of Fernando Alonso.

Red Bull will almost certainly clinch the Constructors’ Championship this weekend at the home race for their engine supplier Honda.

But Verstappen’s team-mate Sergio Perez finished only 11th and a massive 1.396sec adrift of the pace-setter.

The second practice session gets under way at 1500 local time (0700 BST).
