Andrea Stella highlights McLaren 'paradox' over significant turning point

McLaren team principal Andrea Stella has identified F1's April hiatus as a significant moment in the Woking-based team's season, despite describing the pause as a paradox in its eventual impact.

McLaren entered the five-week gap between the Japanese and Miami Grands Prix having endured a difficult opening to the new regulations, with reliability problems and a lack of competitiveness relative to Mercedes leaving the reigning constructors' champions searching for answers.

The Bahrain and Saudi Arabian Grands Prix were postponed for April because of the security situation in the Middle East, creating an unusually long break between rounds three and four.

Rather than pointing to a single upgrade or race as the catalyst for McLaren's recovery, Stella believes the interruption provided valuable time to reassess the MCL40.

"There wasn’t a single event that changed course; rather, it was a growing awareness of the scale of the challenge we’re facing and the adjustments we needed to make," the Italian explained.

"Paradoxically, the enforced break in April probably allowed us to focus entirely on analysing the MCL40’s performance and to fully understand that we needed to redirect or strengthen its development in certain areas of the car."

power units a 'complex issue'

McLaren had suffered through a particularly troublesome start to life with Mercedes HPP's new-generation power unit, with both cars failing to start in China because of electrical problems.

Further reliability issues subsequently affected Lando Norris and Oscar Piastri, while McLaren also found itself behind the Mercedes works team despite using the same power unit.

Stella has previously stressed that Mercedes HPP was not responsible for all of McLaren's problems, but acknowledged that operating as a customer team created disadvantages when attempting to address power-unit reliability and optimise its usage.

That became an important part of McLaren's development process during the April stoppage.

"Furthermore, over the past few months we've had the opportunity to deepen our understanding of the new power unit supplied by Mercedes HPP and to work with our technical partners to work out how best to utilise it," he said.

"It's been a long process, with its ups and downs, but one that’s starting to bear fruit. That said, I expect that optimising the power unit will remain a complex issue throughout the 2026 season."

The clearest evidence of McLaren's revised approach arrived at the Hungarian Grand Prix, where the team introduced a comprehensive aerodynamic package aimed at addressing weaknesses identified during the first half of the campaign.

The upgrades included a revised floor and further aerodynamic developments, with McLaren reporting that the package was designed to improve braking performance and cornering capability.

Norris subsequently secured pole position and converted it into his first victory of the season, while Piastri was also in contention for the win before retiring.

Stella added: "Returning to the car’s performance, it is clear that the Budapest weekend, which brought the first half of the season to a close, was the highlight: not only because of the result, but above all because the aerodynamic package we introduced at the Hungaroring is the result of this change of direction in development and has enabled us to make significant progress in terms of competitiveness."
