Lewis Hamilton continued a record-breaking run for Mercedes by taking another win ahead of his team mate. The race looked set to be a combination of one and two stop strategies, but in the end this was influenced by a late safety car, giving the frontrunners a ‘free' pit stop.
All but one of the drivers stopped twice - most making their second stop behind the safety car - and there were also four different strategies in the top five.
Red Bull's Max Verstappen was the first to commit to a two-stopper, followed by Ferrari's Sebastian Vettel, whose strategy was compromised by a flat-spot in a tussle for position at the first corner. Mercedes driver Valtteri Bottas also pitted as the safety car came out. All three used different strategies.
The safety car allowed Hamilton - who had made his first stop without losing the lead - to make a second stop without penalty, emerging in the lead once more. Several other drivers followed him, pitting under the lengthy safety car period.
Conditions were warm today with track temperatures in excess of 40 degrees centigrade, following a weekend during which the weather fluctuated.
Mario Isola: "The safety car close to the end was the pivotal moment in the race when it came to tyre strategy, effectively ensuring that everyone did a two-stopper, and resetting the gaps so that there was a short sprint to the finish. From the start of the race, it seemed likely we would see a variety of one and two stop strategies, with all three compounds in play. In the end, it probably would have been quite tricky to one-stop, as there was some degree of wear on the soft and medium, at this very severe circuit in terms of energy loadings. Now we remain in Barcelona for the in-season test on Tuesday and Wednesday, when Ferrari and Racing Point will be fielding an additional car for us to test 2020 prototype tyres."
