To start discussing the McLaren topic, it’s necessary to take a step back to last Sunday, specifically to the post-race cooldown room in Barcelona, when Charles Leclerc turned to Oscar Piastri and Lando Norris and asked if they, too, had felt a shift in the balance of their cars toward the end of the race.
The response—or rather, the lack of one—by the two papaya-colored drivers went mostly unnoticed, but it was actually more telling than it seemed. The stunned expressions of the Briton and the Australian—accompanied by a dry “no”—left space for Leclerc’s almost dejected “for me was unbelievable.” It was a quick but meaningful exchange, perfectly summarizing (if any proof were still needed) the difference between what one is driving and what kind of aerodynamic and mechanical gem the other two have at their disposal.
McLaren’s Performance Is Humbling Rivals: What’s the Secret Behind the MCL39?
The quality of the Woking car can be summed up with a simple metric: top speed. Andrea Stella’s cars are rarely—if ever—among the fastest on the straights. That’s because the amount of downforce generated by the MCL39 is so high that, oddly enough, it almost becomes a disadvantage on long straights.
More specifically, what continues to astonish the entire paddock week after week is the car’s ability to manage rear tire temperatures. This makes the MCL39 virtually immune to sliding and, as a result, to overheating. That makes a huge difference—especially on hot circuits. It’s no coincidence that between Miami and Barcelona, McLaren put on a display of superiority that bordered on embarrassing.
This is an area where the others are still struggling, as demonstrated by what happened in Spain a few days ago. In the first stint, the papaya team ran over 20 laps on soft tires while consistently clocking highly competitive lap times. Mercedes also managed the same number of laps on the same compound, only to see performance drop off sharply.
Naturally, rivals aren’t standing still and are trying to understand how to replicate such performance—particularly Ferrari and Red Bull, who with their first major upgrade package introduced in Imola already started modifying their rear brake ducts.
Giving Credit Where It’s Due
That said, there has been no shortage of controversy. The Milton Keynes team in particular has repeatedly requested clarification from the FIA on whether this solution is legal, using thermal images collected via infrared cameras during pit stops. These images clearly showed just how effectively McLaren was managing to avoid tire overheating.
What emerged—following thorough checks by the FIA—was that the British team had simply been the most skilled at exploiting the so-called “grey areas” of the Sporting Regulations. So, metaphorically speaking, it might be time to applaud those who have worked better than anyone else—and roll up our sleeves to try and challenge those who are currently delivering a resounding lesson to the entire paddock.
