Ferrari rolled into Mexico City with a proper test on their hands. The thin air at 2,240 metres above sea level messes with every power unit in ways you don't see at other tracks. So when Charles Leclerc topped both Friday practice sessions, people started asking whether the Scuderia's latest engine upgrade was the real deal or just practice-session smoke. Turns out, it's more nuanced than that.

The upgrade isn't about slapping more raw power into the SF-26. Instead, Ferrari's engineers have nailed something far cleverer: consistency. By managing combustion and electrical energy deployment more smoothly, the package gives drivers a steadier platform to work with. In Mexico, where reduced oxygen and cooling capacity force engineers to balance performance against component protection, that kind of controlled delivery becomes gold dust. Leclerc's double practice lead shows the car's operating inside a sweet spot, but Friday running doesn't tell the whole story because teams were running conservative settings to check temperatures and turbocharger stress.
What makes this genuinely interesting is how Ferrari's tailored the upgrade for circuits like this. The work supposedly became possible after ADUO 2 landed last September, giving the team the tools to coordinate power delivery around specific track demands. Mexico's long straights need electrical support, while the slow corners demand clean power without cooking the tyres. A power unit that delivers consistently across those demands beats one that just chases peak numbers on a straightline.

Leclerc's pace in practice is a proper positive, but here's the catch: qualifying and the race will demand way more aggressive engine modes than Friday offered. That's when you'll really see if this upgrade holds its own. The team's also dialled in a softer setup that prioritises traction, which could protect tyre life and give Ferrari options on strategy. But protection in free practice and protection over a full grand prix distance are two different beasts entirely.

So what's the takeaway? Ferrari's found something genuinely useful, but it's not a magic bullet. The real test starts Saturday afternoon. If Leclerc can keep that pace when the engines turn up and traffic gets involved, Mexico could be the moment this upgrade clicks. If it all falls apart under pressure, then Friday was just another practice session that meant very little.
