F1MATH: Key takeaways from the opening day in Monaco

Pirelli’s evaluation of Friday practice at the Monaco Grand Prix paints a clear picture: the 2026 tyres behaved consistently across all three compounds, degradation was minimal, and the evolving street surface is likely to deliver even faster lap times in qualifying.

With Lewis Hamilton, Charles Leclerc, and Max Verstappen separated by less than two tenths on the C5 Soft, the stage is set for an exceptionally tight Saturday.

úThe headline times came from the C5 compound, with Hamilton topping FP2 in 1:13.026, followed by Leclerc (1:13.137) and Verstappen (1:13.194). All three drivers set their best laps on the Softs, reflecting the compound’s strong one‑lap potential once brought into the correct operating window.

Mileage was also high, as is typical for Monaco Fridays. Hamilton and Leclerc each completed 34 laps, while Verstappen logged 33, using the long runs to build confidence on a circuit where precision is everything.

Pirelli noted a fairly even split between the C4 Medium and C5 Soft across the field. Ferrari focused heavily on the C4, while Verstappen spent more time on the C5.

The only outliers were Lando Norris, who stopped early with an electrical shutdown, and the Aston Martin drivers, who ran exclusively on Softs in FP2.

The C3 Hard appeared only in the early phases of FP1, used primarily for track familiarisation. As Pirelli highlighted, the Hard is unlikely to play a major role in Sunday’s race.

Pirelli Chief Engineer Simone Berra explained the logic behind the compound choices: “Most teams started the Monaco weekend using the Hard compound, with the aim of assessing track conditions and allowing the drivers to build confidence with the circuit.

"The C3 will in all likelihood be the least-used option in the race, in a scenario that should point towards a one-stop strategy, barring any neutralisations.”

Berra emphasised the stability of the Medium and Soft compounds: “Over the course of the day, the other two compounds proved to be consistent. The long runs completed by some drivers did not show any particular degradation, while graining, although it appeared on some front axles, did not impact performance.”

One of the most striking observations from Pirelli was how close Friday’s times were to pre‑event simulations:

“Today’s fastest lap times are just three tenths of a second away from the quickest lap indicated by the teams’ simulations. It is therefore plausible that, already in qualifying, also thanks to the further evolution of the track, which is traditionally very pronounced in the Principality, lap times quicker than the forecasts could be recorded.”

This suggests that the pole time could dip well below the 1:13 barrier if conditions continue to improve.

Berra underlined that the Soft tyre will be the decisive factor in qualifying: “To achieve a strong qualifying performance, it will be crucial to bring the Soft compound into the correct operating window. Teams may adopt different approaches to achieve this, taking into account the unique characteristics of the circuit.”

With 22 cars on track this year, traffic will also be a major strategic variable: “In strategic evaluations, managing traffic will also be critical, particularly in light of the presence of two additional cars on track this year.”
