McLaren fires up 2026 MCL40 as Houldley defends strategic pivot

McLaren’s gaze is already fixed firmly on Formula 1’s next frontier, and inside the Woking factory there is a growing sense that the gamble taken last season will pay off.

As rivals wrestled with the final tenths of performance in 2025, McLaren quietly reallocated its energy toward the sport’s looming regulation reset – a move engineering director Neil Houldley remains convinced was both necessary and timely.

The decision was only possible because of strength. With the MCL39 proving competitive enough to secure the Constructors’ title in Singapore – before Lando Norris narrowly edged Max Verstappen to the Drivers’ crown – McLaren had the luxury of thinking longer term.

Others, Red Bull included, chose to keep pushing development deep into the season. McLaren chose a different path.

The ‘Millisecond’ Long Game

For Houldley, the call to stop development on the 2025 car was rooted in cold performance logic rather than sentiment.

“If we had continued to develop in 2025, we would have certainly gone into 2026 slower than we're going to,” Houldley explained, quoted by RacingNews365.

By that stage of the season, the returns were diminishing rapidly. Gains were becoming increasingly marginal, and the looming complexity of the 2026 rules – from power unit changes to active aerodynamics – demanded focus.

“We were looking for milliseconds; 30 milliseconds was a good upgrade at that point, so when you get to that sort of level, it was clear for us at the time [to stop development on the 2025 car],” the Briton added.

That clarity did not come without risk. Red Bull’s continued push delivered visible late-season gains, sharpening the competitive picture and raising inevitable questions about whether McLaren had stepped away too soon.

“Other teams continued their development, and it certainly gave Red Bull some great gains towards the end of the year, but I still think we've made the right decision, and when we get to 2026, hopefully, that will be proved,” Houldley concluded.

Early signs of momentum

Inside McLaren, belief is now being reinforced by progress on the factory floor. The team has already taken a major step toward the new era, successfully completing the first fire-up of its 2026 challenger, the MCL40, according to The Race.

The milestone was achieved at Woking on Friday, just over a week before pre-season testing begins in Barcelona.

Team principal Andrea Stella was present as staff gathered to witness the car come to life, while McLaren personnel worked closely with engine partner Mercedes to carry out the initial systems checks.

It is an early but meaningful signal that the head start McLaren hoped to gain is translating into tangible momentum. While lap times will deliver the final verdict, the foundations are already being laid – quietly, methodically, and with conviction.

For Houldley and McLaren, the message is clear: sacrificing short-term polish for long-term performance was never about standing still. It was about arriving in 2026 ready to fight from the very first lap.
