The Formula 1 title fight enters its decisive phase, with every race now potentially decisive in the run-up to the season finale. Despite being on the comeback trail, Max Verstappen still faces a considerable gap to Oscar Piastri, which means that even one defeat to the McLaren drivers could all but end his championship hopes. The Mexican Grand Prix therefore becomes crucial, with the battle set to unfold in the thin air of Mexico City. The same challenge also applies to the fight for second place in the Constructors’ Championship between Mercedes, Red Bull and Ferrari, with the Scuderia from Maranello paying particular attention to brake cooling.
Engines under pressure in the thin air
The central theme of the Mexican weekend is altitude, with the Autódromo Hermanos Rodríguez circuit sitting 2,200 meters above sea level. At such heights, the lack of oxygen affects not only the drivers but also the cars. Air density drops by about 25% compared to sea level, impacting multiple areas of performance. One of the main consequences is the loss of power from the internal combustion engine, forcing the MGU-H to work harder to spin up the turbo and compress more air. Although the power units are now closely matched in performance, there remain some differences. Honda engines, for instance, have always stood out for their strong hybrid energy recovery and smaller turbo — features that perform better at high altitude, a factor Verstappen and Red Bull hope to capitalize on this weekend.
However, engine power will not be the only decisive element. In Mexico City, drivers run at full throttle for only 61% of the lap distance — one of the lowest figures of the season, behind only Singapore (59%) and Monaco (56%). That statistic favors McLaren, whose car performs best in medium-speed corners, particularly in the sweeping middle sector taken at around 170–180 km/h. Still, the team from Woking must deal with its own weaknesses, especially in the four corners taken below 100 km/h and the five others under 130 km/h. These slower zones, preceded by mostly straight braking areas, make it difficult for Lando Norris and Oscar Piastri to feel the car’s grip limit, although they can take comfort in the fact that Red Bull is not particularly strong in low-speed sections.
Monaco wings, Monza downforce
The rarefied air also reduces the effectiveness of aerodynamic surfaces, forcing teams to run large Monaco-style wings but still generating less downforce overall than at Monza. Simulations confirm this, with predicted lateral acceleration peaking at just 3.6 g compared to the usual 5 g these cars can achieve — clear evidence of reduced grip levels. In such conditions, driver sensitivity becomes a key factor, and it is perhaps no coincidence that Verstappen holds the record for five victories in Mexico.
The mantra for every driver will be to respect the car and avoid overpushing to prevent excessive tire slip and overheating. Pirelli will bring the same C4 and C5 compounds used last year, but as seen in Austin, the third option will be two steps harder than the medium compound, encouraging teams to favor softer tires. The 2024 race showed very little degradation, a trend expected to continue this year, potentially limiting McLaren’s advantage in race pace.
Meanwhile, the reigning double world champions can rely on the MCL39’s excellent cooling efficiency. The thin air makes heat dissipation difficult, forcing teams to open up larger cooling vents and run their widest bodywork of the year, at the expense of aerodynamic efficiency. McLaren, however, remains unconcerned, as its superior cooling system allows it to keep tighter bodywork even in hot conditions — a design advantage that can save valuable hundredths on the straights.
Ferrari’s focus on brake cooling
When it comes to managing temperatures, Ferrari’s top priority will be ensuring effective cooling of the braking system. The painful memory of Singapore still lingers, where a miscalculation led to a disastrous Sunday. Both drivers were forced into an unusually heavy lift-and-coast strategy, with Lewis Hamilton narrowly avoiding retirement in the closing laps. Even with everything under control, a repeat of Ferrari’s 2024 victory — their last win in Formula 1 — appears unlikely, with the more realistic goal being to reclaim second place in the Constructors’ standings.
Achieving that will not be easy. Mercedes has made solid progress since the summer break thanks to work on the floor, the flexibility of the front wing, and improvements to brake ducts. The Mexican track also lacks high-speed corners, which prevents the W16’s weaknesses from being exposed. The fight for second place will nonetheless be a three-way battle, as Red Bull remains in contention thanks to Verstappen’s wins and Yuki Tsunoda’s consistent points finishes. The Milton Keynes team still has some updates in development, and it remains to be seen whether they will debut them in Mexico or at a later round.
Execution and adaptability will be decisive
More than any single car’s characteristics, the key to success in Mexico will lie in the weekend’s execution — from setup choices to race strategy. Complicating things further, several regular drivers will have to give up their seats to rookies during FP1, reducing their preparation time. At Red Bull, Verstappen will hand over his car to Arvid Lindblad, while Norris will make way for local hero Patricio O’Ward at McLaren. Ferrari and Mercedes will also participate in the rookie sessions, with Antonio Fuoco replacing Hamilton and Frederik Vesti stepping in for George Russell.
As 2025 has already shown, qualifying execution will again be crucial, especially given the likely low tire degradation during the race. Altitude may also play a role here, as the circuit is known for rapid temperature fluctuations within minutes, drastically changing track conditions. The ability to adapt in real time could make the difference in securing a front-row start — though not necessarily pole position. The long run down to Turn 1 often leaves the pole-sitter vulnerable to slipstream attacks, rewarding strategic awareness and aggression into the first chicane. Verstappen has mastered this scenario many times before, but if McLaren can position both cars effectively, teamwork could be their best weapon to disrupt the Dutchman’s plans.
