Defending a Formula 1 title is meant to be a victory lap of sorts, a season spent fending off challengers rather than chasing them. McLaren entered 2026 as reigning champions expecting exactly that. Instead, the team finds itself fighting to be the best of the rest, an unexpected demotion that has reshaped its year and forced a reset of expectations both inside the garage and among its supporters.

The standings make the shift plain. Lando Norris sits fifth on 73 points and Oscar Piastri sixth on 68, both adrift of the two Mercedes drivers and Lewis Hamilton. McLaren hold third in the constructors’ championship, respectable on paper but a clear step below the level the team set last season.

A quirk in the tyres at the heart of the slump

Norris has pointed to a specific 2026 factor behind the decline. The new regulations brought reduced downforce, and alongside it, rising tyre pressures that have altered how the Pirelli rubber behaves. Together, those changes have moved the car away from the window where it previously thrived.

It is a subtle problem rather than a dramatic one. The car is not fundamentally broken, but the combination of less downforce and different tyre characteristics has quietly eroded the edge that made McLaren champions. Small shifts in tyre behaviour can have outsized effects on grip and consistency.

Crucially, these are not faults a team can simply bolt away overnight. Adapting to a changed tyre operating window demands setup work, development direction, and time, none of which deliver instant results in the middle of a competitive season.

The frustration is sharpened by how recently McLaren held the upper hand. The car that dominated last year was built around exploiting the previous tyre and aero balance, and the new rules have shifted the ground beneath it. Strengths that once set the pace no longer translate the same way.

Piastri’s grip struggles in Barcelona

The issue was visible in Barcelona. Piastri finished fifth, a solid result on paper, yet he admitted afterwards that he ‘had no answers’ on grip. Salvaging points from a weekend where the car would not cooperate underlines both his racecraft and the depth of the problem.

That candour is telling. A driver finishing fifth while openly conceding he could not unlock the grip he needed paints a clear picture of a team performing below its ceiling. The result flattered a weekend that, from inside the cockpit, felt like a constant fight against the car rather than a battle with rivals.

McLaren themselves have not hidden behind excuses. The team has acknowledged it cannot fight for wins in its current form, a striking admission from an organisation that was setting the pace only a season earlier. Honesty about the deficit is often the first step toward addressing it.

How the title defence unravelled early

The low point arrived in China, where both cars failed to even start the race. Separate power-unit electrical issues sidelined Norris and Piastri before the lights went out, a double blow that handed away points the team could ill afford to lose so early in the campaign.

Two cars failing to start for unrelated reasons is the kind of misfortune that can define a season’s narrative. It set an early tone of frustration and put McLaren on the back foot before the deeper performance questions had even fully emerged.

Points lost so early are hard to recover, and a non-start surrenders them in the most painful fashion. Where a struggling car might still salvage a handful of finishes, an empty grid slot yields nothing. Those zeros in China helped open the gap McLaren are now trying to close.

Can McLaren turn the defence around?

The Austrian Grand Prix offers a fresh chance to gather data and refine the package. The Red Bull Ring’s short lap and traction demands differ from Barcelona’s long, flowing corners, which may suit the car’s characteristics differently and offer clues about where the real weaknesses lie.

Recovering to genuine title contention would require closing the gap to Mercedes and Hamilton, a substantial task with the season already past its early stages. The more realistic near-term goal is consolidating the best-of-the-rest position while the engineers chase a deeper fix.

Having two drivers capable of extracting maximum points is a meaningful asset in that effort. Norris and Piastri have both shown they can wring strong results from a difficult car, and that consistency keeps McLaren in third while the team works to restore the outright pace it has lost.

For a team that began the year as champions, the present reality stings. Yet the diagnosis is clear, the drivers remain strong, and the deficit is rooted in an understood quirk rather than a baffling mystery. That gives McLaren a foundation to build on as the season continues, and a clear target to chase as development arrives at the car.

Frequently asked questions

Where do Norris and Piastri sit in the standings?

Norris is fifth on 73 points and Piastri sixth on 68, both sitting behind the two Mercedes drivers and Lewis Hamilton. McLaren are third in the constructors’ championship, a step below the level they set as champions last season.
