McLaren introduced in Miami a first significant set of upgrades on the MCL40, with visible modifications on several key areas of the car.

In Miami, McLaren did not hold back. The British team brought a series of important upgrades to its MCL40, the first step of a two-phase plan that will continue at the next event in Canada.
While the Mercedes engine advantage is well identified in the paddock, the team had so far acknowledged a deficit in aerodynamics. This package aims precisely to close that gap. Team principal Andrea Stella was particularly attentive to the overall context of the weekend, marked by a massive wave of upgrades among its competitors, including Ferrari.
“When we saw the list of upgrades presented by the teams on Friday, we noticed that practically everyone was bringing a new car – or at least half the grid – so we said to ourselves: let’s see who did the best job.”
“I have to say that, as they have already demonstrated in the past, the men and women of McLaren did a really remarkable job designing, manufacturing, and delivering these upgrades. So it’s encouraging to see the team again in a leading position during a qualifying session, even if it’s only Friday and in the context of a sprint qualifying.”
Targeted upgrades on several key areas
Our exclusive images reveal a series of coherent modifications aimed at improving the management of airflow over the entire car, adding to the fins placed on top of the engine cover (image above).
As seen in the image above, the bargeboard has been modified. Its profile is now curved (compare the yellow arrows).
The flat floor inlet (under the air intakes) is clearly inspired by Ferrari’s design. The “teeth” have been reshaped following the model of their Italian counterparts and a small intermediate deflector has been installed (see the red arrows in the image above).
While the initial MCL40 did not have an opening in the diffuser walls (unlike its rivals), it now has one, as can be seen above by comparing the areas indicated by the yellow arrows.
At the rear, McLaren introduced a fin around the exhaust outlet, following Ferrari’s model. A small wing is positioned behind the outlet, accompanied by a lower element that guides the flow upwards.

The goal is twofold: to use the hot gases to energize the flow at the diffuser exit and improve the interaction with the rear wing.
Finally, the rear wing itself receives a rib on its endplate, a solution already seen elsewhere on the grid, aimed at refining the control of marginal vortices.
Norris confirms: “It’s nice to regain grip”
These upgrades seem to already produce tangible effects. Lando Norris secured pole position for the sprint race, a result he partly attributes to the new package.
“It was great. Perfect result for us, a nice way to reward the team.”
“We have a lot of new upgrades on the car, so it’s nice to regain grip, and to reward the guys and girls who worked very hard.”
“I’m happy to be back here. It had been a while, so it’s a perfect way to start the weekend.”
While this first package already represents a visible and structured upgrade, McLaren is only halfway through its development plan.
The second phase expected in Canada will allow a full assessment of the effectiveness of this technical direction. But in Miami, the first signals are clear: McLaren seems to have taken a step forward in its aerodynamic understanding of the MCL40.
