Norris

McLaren have fallen to the back of the top four teams in recent races as rivals have introduced upgrades, but the hope is that the aerodynamic package to be brought in across the Hungarian and Dutch Grands Prix on either side of Formula 1’s summer break will return them to competitiveness.

They decided that it was better to take the grid penalty in Belgium, where they expect to be no more competitive than at the last race in Britain but where passing is relatively straightforward, than compromise Hungary, where the car should perform better and overtaking is notoriously difficult.

Norris said: “I have to wait and see really how the overtaking is. We probably have a small straight-line speed advantage, comparing to people a little bit further back. So comparing to them we should have a good chance.

“To just overtake in general could be pretty difficult here. But the slipstream is pretty big, and there’s still a few straights, but there’s no straight-line mode (through some of the flat-out sections), and therefore the slipstream is pretty large, and you can gain a good amount from that.

“But we know it’s better than Zandvoort, and better than Hungary taking penalties. I hope it’s not the end of my weekend before it started, but I’m still confident we can have a good race.”

Norris’ grid penalty comes after a troubled start to the season for the team that won a drivers’ and constructors’ championship double last year, in both performance and reliability terms.

Technically, the part replaced in Belgium is known as the ‘power electronics’, which is a control computer within the battery module.

Norris failed to start the Chinese Grand Prix in March after a terminal issue with his power electronics unit, and a second example of that part had to be withdrawn after suffering problems in practice at the following race in Japan.

The Japan unit was repaired but suffered a terminal problem in practice in Monaco.

A McLaren statement said: “While the power electronics unit we installed in Japan, and have used in every session since Miami, has worked reliably, Mercedes-AMG High Performance Powertrains (HPP) has since introduced a series of reliability fixes to their new power electronics systems.

“However, in order to take advantage of these improvements, we must incur a 10-place grid penalty on Lando’s car in order to take a new unit.”

The statement added: “We now plan to use this fourth power electronics unit for the remainder of the season, in order to maximise reliability while minimising sporting penalties on Lando.”

McLaren will have a new rear wing design in Spa, which the team hopes will better suit the specific characteristics of the flowing high-speed track around the Ardennes forests.

This wing will have a conventional opening style in straight-line mode, rather than the somersaulting designs introduced this season by Ferrari and Red Bull.

Red Bull have had to revert to a conventional wing this weekend after Max Verstappen suffered high-speed crashes at the previous two races because of issues with the design.

Mercedes have had a series of engine-related reliability issues this year, not all to do with the battery.

Another has emerged with the engine used by championship leader Kimi Antonelli at the British Grand Prix.

That has had to go back to the HPP’s base in Brixworth for investigation and the Italian has a new engine as a result this weekend in Belgium. This is from within his allocation and therefore comes with no penalty.

Depending on the outcome of the investigations, Mercedes hope to be able to put Antonelli’s Silverstone unit back into the pool for use later in the year.

Norris was left to rue the pit stop decision – “How did we not win this?” he said over the radio. “We can make it easier for ourselves.”

But this was a strong showing from McLaren, who introduced a major upgrade package this weekend, which brought them right into the fight with Mercedes.

Leclerc was brought in on lap 21 for his stop, and complained over the radio that he had not been consulted.

The decision did drop him down the field and force him to fight past slower cars. He regained third, but then lost it again to Norris’ team-mate Piastri on the penultimate lap as he began to struggle for grip.

Leclerc then spun on his own on the last lap, shortly after Piastri had overtaken him, and he lost two further positions into and out of the final corner, as first Russell and then Verstappen came past him.

Verstappen pitted under the safety car for his fresh tyres, hoping the gamble would pay off. It dropped him to the back, but with some aggressive overtaking and the others pitting in front of him, it put him in the lead mid-race.

But he was never going to hold on with his worn tyres, and he slipped down. Still, fifth was a decent result after his early error, which was followed by some very aggressive racing that prompted complaints from some of his rivals.

Leclerc slipped back to sixth, ahead of team-mate Lewis Hamilton, whose car was damaged in a first-lap clash with Alpine’s Franco Colapinto.

The Argentine took eighth, ahead of the Williams cars of Carlos Sainz and Alex Albon.

Verstappen faces an investigation from the stewards for crossing the white line on pit exit, while a collision between Russell and Verstappen while they were racing in the closing stages and in which the Mercedes’ front wing was damaged is also under consideration.

It was Norris’ first pole since Las Vegas last year, three races from the end of his championship season, and a suggestion – at the very least – that Mercedes may not have things all their own way this year, after all.

Antonelli salvaged a good result for Mercedes after a difficult session.

The Mercedes car has often struggled in the heat, and the 32C temperatures did not seem to do it any favours.

But after not looking competitive for most of the session, Antonelli ensured he was the very last car to set a time in the final session, when the track would be at its grippiest, and it paid off.

“It was a pretty messy session,” the Italian said. “I struggled a lot with the car and on the medium (tyres) I couldn’t get a lap in, and then on the soft, all of a sudden, the car became more alive. I felt more comfortable.

“We definitely felt we were expecting this weekend to be quite a bit tougher, also because those teams brought major upgrades which they closed the gap massively, or even went in front of us. McLaren have the same engine as us and they improve a lot the car, but I think we can be in the fight.”

Russell took the opposite route, running first, and he ended up 0.4secs back from his team-mate, not an ideal result given he already has to make up nine points on Antonelli in the championship.

“Pretty surprising how big a jump McLaren and Ferrari have made,” Russell said. “That’s pretty damn impressive. All day they’ve been quicker than us. From my side, I’ve been struggling all day.

“Miami is not a track I particularly love, especially in these hotter conditions, but it’s only sprint qualifying. Just overheating the tyres a lot in that twisty section in the middle. Struggling to get the right balance with the car.”

The Ferrari was very fast through practice and the first two qualifying sessions on the medium tyre, but struggled on the soft in the final session.

“The upgrades are fine,” Leclerc said. “It’s just everybody brought upgrades. McLaren did a very big step forward but I felt like they didn’t optimise their first races so they were always there but didn’t put everything together.

“On our side, we have struggled with tyres. The medium were working very well. On the soft, it was not a nice feeling, so on that we have got to look at it. We know on the race pace we are stronger but in terms of qualifying there is still work to be done.”
