The 2025 Formula 1 Brazilian Grand Prix presents McLaren with two major challenges. On one hand, Lando Norris and Oscar Piastri continue their fierce internal battle for the drivers’ championship. On the other, the team from Woking faces the relentless threat of Max Verstappen and Red Bull, determined to return to victory at Interlagos. The British outfit has all the technical tools to win — but must avoid costly errors in the opening practice session.
The aerodynamic efficiency mistake to avoid
The Brazilian circuit is made up of a combination of technical corners and fast straights, demanding the perfect balance between aerodynamic load and mechanical grip. The key sections are the long full-throttle stretch leading from the final corner to the finish line, and the sequence connecting Turn 3 to Turn 4. Here, top speed and drag efficiency make a crucial difference.
McLaren has consistently demonstrated high aerodynamic efficiency and, in past editions of the Brazilian GP, has managed to strike a solid balance in terms of downforce. However, in the 2024 event, the team made a costly misjudgment when setting up the car. Their technical department was confident enough to aim for pole and victory, focusing their setup on maximizing straight-line speed with heavy DRS reliance. But when the race turned wet, the inability to use the DRS turned their advantage into a major weakness — leaving both drivers unable to make any overtakes.
With the right setup, the MCL39 could be almost unbeatable
Heading into the 2025 weekend, expectations remain high for a competitive McLaren. The MCL39 offers a wide setup window, and the car’s strong ground-effect downforce could play a decisive role at Interlagos. Although the circuit’s surface was improved before the 2024 race, its natural undulation still causes significant bumps, complicating the task of finding the ideal ride height.
Unlike Ferrari, McLaren has developed an effective way to limit floor wear, allowing the team to run the car lower than its rivals — a small but significant gain in performance. Even minor adjustments to ride height can deliver meaningful lap time improvements, and in a short circuit like Interlagos, every fraction of a second counts.
The British team therefore enters the weekend with strong technical foundations, though much will depend on how precise the engineers are with setup work. Because the Brazilian GP is also a Sprint weekend, teams only have one hour of practice before qualifying, leaving no room for hesitation or setup errors.
McLaren working to reduce tire graining
At the 2024 Brazilian Grand Prix, tire management proved to be the decisive factor. McLaren excelled by keeping its tires within the optimal temperature range for most of the lap, ensuring stable performance. Although tire wear was evenly distributed between the front and rear, the Woking team’s strength lay in maintaining consistent grip, which proved essential before rain changed the race conditions entirely.
When track temperatures are close to the ideal range, tire pressures remain stable, resulting in a maximized contact patch. However, during the brief dry running in 2024, teams noticed a high level of graining on the rear tires. This issue led Pirelli to bring a harder range of compounds for the 2025 edition in an effort to mitigate that phenomenon.
If Pirelli’s updated strategy works as expected, we could see less graining this year — although McLaren’s aggressive aerodynamic setup still makes it slightly more vulnerable compared to other cars. Overall tire degradation is expected to remain low, which could help narrow the performance gap between McLaren and Red Bull, setting the stage for another intense battle at Interlagos.
