On the first day of track action for the Monaco Grand Prix, Charles Leclerc made the most of being on home turf. The Ferrari driver, who was born here and won last year at this track was surprisingly quickest in both free practice sessions: 1’11”964 in the first one and 1’11”355 in the second.

Clearly, Ferrari is looking very competitive as Lewis Hamilton was third in the second session in 1’11”460, but the McLarens are up there too, with Oscar Piastri second just 38 thousandths slower than Leclerc, while Lando Norris is fourth in 1’11”677.


THE DAY ON TRACK:
All three compounds were used over the 120 minutes of practice. The Soft did the most work (574 laps in total), followed by the Medium (427) and then the Hard (221). 13 drivers have already used a set of C4 and will therefore only have one available for Sunday’s race when, as per the modified Sporting Regulations, two tyre changes will be obligatory.


Simone Berra: Chief Engineer:
“Quite a busy day with lots of laps and plenty of data gathered. It was important for us to see how the C6 performed after it made its debut in Imola and we can say that, here too, the indications we saw last week were also confirmed today. The softest tyre in the 2025 range is slightly faster than the C5 and, with one or two cool-down laps, recovers much of its performance. It was also clear that, given that it exhibits the traits of an extremely soft compound, the drivers might feel a little less confident with it when trying to push for a time right from the first flying lap. This could potentially open the door to the Medium also being used in one or more segments of qualifying.

Furthermore, with the special sporting regulation in place for this weekend, the choice of tyres for the grid-deciding session will have a significant knock-on effect for the race. For example, today 13 drivers from seven teams chose to already use a set of Hards, thus having just one left for Sunday. Five drivers, (Piastri, Norris, Hamilton, Hadjar and Lawson), used one set of Mediums in each of the two sessions.

As is often the case in Monaco, the lap times came down bit by bit with every passing lap, partly because the track is rubbering-in, with a new surface from turn 12 to 3, but mainly because the drivers grow in confidence. However, the times have been slightly slower than in the same session last year, when once again Leclerc was fastest, in 1’11”278.

From a tyre wear perspective, we saw some graining on the Mediums at the end of the long runs, something which is totally predictable at this track and in these conditions."


FORMULA 2:
Three thousandths of a second: that was the difference between the times set by Alexander Dunne (Rodin Motorsport) and Victor Martins (ART Grand Prix) in today’s qualifying: 1’21”142 for the Irishman, 1’21”145 for the Frenchman, who were first in their respective groups, as here in Monaco the F2 drivers are split into two sessions for qualifying.

The compounds chosen are the softest in the Pirelli range, namely Soft and Supersoft. At a track that has remained more or less unchanged for 70 years, running through the tight and twisty city streets, qualifying plays a key role in deciding the outcome of the races, especially given the difficulty in overtaking.

In last year’s Feature Race, the majority of drivers opted to start on the Soft with the aim of running as long a first stint as possible, thus delaying the switch to the Supersoft. The softest compound required careful management over its first few laps to avoid graining. In Monaco, there is always the chance of a Safety Car and guessing the right window in which to pit can be the key to winning. The 2024 race was a good example of this, when Zak O’Sullivan pitted on the penultimate lap, taking advantage of a VSC.


FORMULA 3
Bulgaria’s Nikola Tsolov is the Monaco pole-sitter. The Campos Racing driver set a best time of 1’24”882 in the first group, ahead of team-mate, the Spaniard Mari Boya. The quickest in the second part of the session was Poland’s Roman Bilinski (Rodin Motorsport) 1’25”332, third fastest overall.

The Soft is the compound chosen for Monaco. With this being the circuit with the lowest average speed of the season, the softest compound in the range experiences moderate degradation, as the forces exerted on the tyres are minimal. Last year, graining began to make itself felt after around eight laps, on both the front and rear axles, resulting in a drop in performance, although it remained manageable.

As always in Monaco, qualifying plays a crucial role, even if overtaking in F3 is slightly easier than in F1 and F2, due to the cars being slightly smaller in size.
