On a hot day in Sochi, with ambient temperatures in excess of 30 degrees, we saw a variety of strategies, as a result of bringing compounds that were a step softer than last year. In the past, Sochi has been mainly a one-stop race, and this was generally the case again but with all three compounds coming into play as part of the different strategies. Managing thermal degradation was key, especially on the soft, but we also saw some particularly long stints on the hard. Congratulations to Valtteri Bottas and also to Mercedes – which keeps up its unbeaten record at the Russian Grand Prix.
