Mercedes driver George Russell reckons Ferrari has quite an advantage
at F1’s Mexican Grand Prix with its turbo design, while Charles Leclerc still believes Mercedes has the best car wherever we go
. The differing assessments set the stage for an intriguing competitive battle as the Formula 1 paddock travels to Mexico City’s Autodromo Hermanos Rodriguez, where the extreme atmospheric conditions place rare and critical demands on power unit architecture.
High Altitude and Engine Architecture in Mexico City
Mexico’s capital megalopolis sits on a 2250m plateau, which gives the Autodromo Hermanos Rodriguez one of the most unique engineering challenges. The lower-density air reduces aerodynamic performance and has major cooling headaches, but it may also reward Ferrari for some of the design decisions it made with its 2026 power unit. Boasting a smaller diameter turbocharger compared to its rivals, the turbo’s lower inertia allows it to spool up quicker, which has a compound effect when the air is much thinner at altitude and there is less exhaust energy available to begin with. The trade-off is a limit on peak horsepower compared to larger diameter turbines.
Anticipating the hurdles that teams will face navigating the thin air, Russell highlighted the performance implications: I think it’s going to be very interesting. I think turbo lag is going to be a big factor for a lot of teams this weekend,
Russell pointed out. There’s obviously no secret that the likes of Ferrari have a smaller turbo than most, so they probably have quite an advantage in this regard. We’re not sure as yet how challenging it will be, but I can definitely foresee it being not straightforward.
Charles Leclerc Downplays Ferrari’s Frontrunner Status
Ferrari’s Leclerc was quick to play down his team’s favourite tag, coming after a series of wins for Max Verstappen in the significantly improved Red Bull and a victory in Austin for champion-elect Kimi Antonelli in the Mercedes. Ferrari, which also introduced significant upgrades last weekend, hasn’t won a grand prix since Leclerc triumphed at July’s British Grand Prix in Silverstone.
Despite recent strong showings, Leclerc remained grounded regarding Ferrari’s standing: Honestly, I think it’s getting very close, and we have good momentum,
Leclerc said. With Singapore and Austin as well, we’ve maximised our potential, and I was relatively happy with the pace we’ve shown.
He continued by pushing the expectations back onto Mercedes and Red Bull: Whether we are the favourites for this weekend, I don’t fully agree. I think Mercedes remains the favourite wherever we go. Red Bull are very, very strong as well recently. But if we maximise everything we have, then I hope it can be a great weekend for us.
Qualifying Execution Remains Decisive for the Scuderia
Ferrari has developed a habit of being very strong at getting up to speed quickly during Friday practice, only to be overhauled by its rivals when it matters in qualifying. So, with F1’s four top teams as close as they have been all season on pure pace, Leclerc acknowledged that executing a clean qualifying session is crucial to avoid a repeat.
Addressing the fine margins, Leclerc observed: As we’ve seen, I think the optimisation of our package is what will eventually make the most difference,
Leclerc pondered. It’s so difficult to put everything in the right window coming into qualifying that, if we manage to do so, I think we’ve got a chance here.
Why This Matters
The technical nuances on display at the Mexican Grand Prix trace back directly to power unit philosophy. Ferrari’s turbo choice was partly driven by the need to spool up at the start of a race without assistance from an MGU-H system, which was shelved for the 2026 regulations. A smaller turbo would theoretically have allowed the squad to execute the complicated 2026 start procedure more consistently, but an eleventh-hour change to the procedures by the FIA on safety grounds negated some of Ferrari’s advantage.
As the frontrunning pack tightens heading into the closing rounds, the Mexico City weekend serves as an ultimate operational test of engine responsiveness and thermal management. The high elevation could disrupt recent balance-of-power trends established by Mercedes and Red Bull, giving Ferrari an engineering pathway to bridge the performance gap if they can successfully convert their low-inertia turbo benefits into qualifying track position.
Frequently Asked Questions
Why does Ferrari’s turbo provide a potential benefit in Mexico?
Because the Autodromo Hermanos Rodriguez is located 2,250 meters above sea level, thin air creates severe turbo lag due to limited exhaust energy. Ferrari’s smaller-diameter turbocharger features lower rotational inertia, allowing it to spool up significantly faster than larger units used by competitors.
When did Ferrari last win a Grand Prix this season?
Ferrari’s most recent Grand Prix victory occurred at the British Grand Prix at Silverstone in July, where Charles Leclerc secured the win.
Why did Ferrari originally choose a smaller turbocharger design?
Ferrari’s concept was originally influenced by the need to spool up at race starts without an MGU-H under the 2026 engine regulations, though a subsequent late safety adjustment to the start procedures by the FIA diminished some of that planned competitive edge.
