Head of Pirelli Motorsport Mario Isola analyzes the 2018 French GP. Seb made a pit stop under the safety car due to car damage.

Lewis Hamilton won a race for Mercedes that was heavily influenced by the first lap, when two of his rivals clashed and a safety car came out for five laps. A number of drivers made a pit stop under the safety car due to car damage, notably Scuderia Ferrari driver Sebastian Vettel and Mercedes driver Valtteri Bottas, who both switched onto the soft tyre on lap two before making a second stop in the closing stages of the race. Both finished in the points, having dropped to the back, after capitalising on this improvised strategy to move up the leader board as others stopped.

The strategy for Mercedes and Red Bull was to start on supersoft: Hamilton (along with runner-up Max Verstappen) then switched onto soft for the final stint. Ferrari’s Kimi Raikkonen adopted an alternative one-stop strategy that resulted in a strong podium finish.

Pirelli Motorsport‘s Head of Car Racing, Mario Isola, revealed that the compound tyres did what they hoped it would – lead to more strategy variations: “An uncertain weather forecast added to the strategic game today, with the risk of rain meaning that teams wanted to avoid the risk of getting caught out on the wrong type of tyre. As it was, the rain didn’t actually materialise, but it was another potential factor to bear in mind. As expected this was a one-stop race for most drivers, but there was a wide variety of one stoppers, including some very long stints on the soft tyres. We also saw Sebastian Vettel and Valtteri Bottas complete the race strongly with two very different two-stoppers, with Ferrari and Mercedes having split their strategies across each of their cars, reacting to the race circumstances. This confirmed our expectation that all three compounds were valid choices as part of an overall race strategy today, delivering a strong performance throughout.” – he explained.

Lewis Hamilton won the race using a one-stopper as expected, switching from supersoft to soft on lap 33. This was the same tactic adopted by Max Verstappen in second, although the Red Bull driver stopped much sooner. Ferrari’s Kimi Raikkonen in third went for a completely different option, starting on ultrasoft and finishing on supersoft. This enabled the Finn to make a crucial pass in the closing stages of the race that earned him a podium.
