Key Highlights
- Red Bull Team Principal Laurent Mekies warns that Mexico City’s high elevation and intense cooling demands could create a one-off shake-up in Formula 1’s competitive order.
- Despite an early power unit issue for Isack Hadjar in opening practice, Red Bull reported no unforeseen complications directly caused by altitude.
- Red Bull’s advanced Milton Keynes wind tunnel project is slated to go online in 2027, with performance benefits expected to impact the 2027 and 2028 car designs.
Altitude and Cooling Challenges at Autodromo Hermanos Rodriguez
The unique atmospheric conditions of the Mexico City Grand Prix could significantly disrupt the established Formula 1 running order, according to Red Bull Team Principal Laurent Mekies. Addressing the media during Friday’s official press conference following Free Practice 1 at the Autodromo Hermanos Rodriguez, Mekies highlighted the intense operational hurdles posed by the circuit’s extreme elevation of over two kilometers above sea level.
The dramatically thinner air typical of Mexico City reduces downforce and compromises cooling efficiency, requiring engineers across the paddock to implement severe packaging and aerodynamic compromises. When asked whether the thin air had triggered problems for Red Bull’s power units, Mekies outlined the team’s early findings: “I think there have been no unforeseen issues so far related to the altitude,”
he noted. However, the session was not entirely uninterrupted. “In fairness, we did have a PU issue with Isack [Hadjar] this morning and lost a bit of track time. The guys did a very good job and managed to send him back on track, but that was not linked with altitude.”
Predicting a Potential One-Off Shift in the Pecking Order
Because the atmospheric demands force teams to prioritize operational survival over pure performance, Laurent Mekies expects the race weekend to present an unusual competitive dynamic. The necessity of keeping internal components within viable thermal thresholds means teams cannot run their packages at maximum theoretical efficiency.
“Both in terms of PU for the altitude and with all the compromises we are all having to make on the cooling side, we expect that this race could be a one-off in terms of pecking order,”
Mekies explained. He cautioned that it remains uncertain which constructors will manage these constraints most effectively. “We don’t really have an idea whether we will have an advantage or a deficit this weekend. Only time will tell. But there is a fair amount of lap time, both on the PU side and the chassis side, that is in the game this weekend.”

The compromises made by power unit manufacturers and aerodynamic departments mean that survival and reliability will go hand-in-hand with raw pace. As Mekies stressed: “In many respects everybody will not be operating at the optimum this weekend – PU side for the altitude, chassis side for the temperature. We are all ready to make some compromises to make sure our car can survive and our PU can survive in these conditions.”
Timeline and Expectations for the New Milton Keynes Wind Tunnel
Beyond the immediate engineering test in Mexico, Laurent Mekies offered important updates regarding the construction of Red Bull’s state-of-the-art wind tunnel at its Milton Keynes headquarters. The facility will eventually succeed the team’s longstanding aerodynamic base in Bedford, representing a vital infrastructure shift in their long-term technical roadmap.
“As much as the wind tunnel we are using has ultimately been producing extraordinary results over the last few years, it is most likely the oldest one on the grid,”
Mekies noted. Discussing the potential transition, he stated: “As a result, if you jump to a state-of-the-art facility, of course you expect a competitive advantage from there. It’s not going to come as soon as we switch everything on, but it’s certainly going to unlock potential and give the talented people we have in the aero department another way to express their ideas.”
Detailing the targeted commissioning phase, Mekies clarified the expected timeline: “It’s not ready yet. It’s something that will come online sometime during next season. Is it the first quarter, second quarter or third quarter? We will see. But it will be based on how much time we need to complete the calibration work and get it online first. So, it will most likely be for the second half of the 2027 car and hopefully for most of the 2028 car.”
The modernization plans address concerns previously raised by four-time World Champion Max Verstappen. Speaking to Viaplay earlier in September, Verstappen jokingly described the Bedford installation as a wind tunnel “that comes from World War II”
, emphasizing: “Of course you hope that as a team you can make a step there as well.”
Why This Matters
The Mexico City Grand Prix represents an annual operational stress test for Formula 1 machinery. The circuit sits approximately 2,240 meters above sea level, causing air density to drop by nearly 25 percent compared to standard sea-level tracks. This requires power unit turbochargers to spin faster to maintain boost pressure while drastically reducing airflow across radiators, forcing aggressive cooling gills, enlarged engine covers, and elevated thermal risks that can reshuffle the competitive field.
Looking at long-term competition, aerodynamic testing infrastructure remains the backbone of contemporary Formula 1 development. Red Bull’s reliance on its aged Bedford site has drawn scrutiny despite historic championship successes. By establishing a modern facility directly in Milton Keynes, the outfit aims to streamline calibration times, refine airflow simulation accuracy, and ensure their engineering group possesses the necessary tools to sustain elite performance into the 2027 and 2028 seasons.
Frequently Asked Questions
Why does the high altitude of the Mexico City GP affect Formula 1 cars?
Sitting over 2,000 meters above sea level, the track features thinner air, which depresses aerodynamic downforce and significantly reduces engine cooling efficiency. Teams are forced to modify their chassis packaging and engine settings to safeguard reliability against thermal and mechanical strain.
What caused Isack Hadjar’s issue during Free Practice 1?
Isack Hadjar experienced a power unit issue during FP1, but Red Bull Team Principal Laurent Mekies confirmed that the problem was isolated and unrelated to the circuit’s elevated altitude. Hadjar was able to return to the circuit following swift repairs by the team’s mechanics.
When will Red Bull’s new wind tunnel be ready for car development?
According to Laurent Mekies, the Milton Keynes wind tunnel is slated to become operational in 2027, subject to necessary calibration work. The performance and development benefits are expected to influence the second half of the 2027 chassis development and the full 2028 car.
