With the track always evolving so quickly in Sochi, it’s not easy to draw any firm conclusions on a Friday. However, we’re seeing that the lap times are getting dramatically faster throughout each session. The compounds also seem to be quite evenly spaced out in terms of performance, which is what we wanted to achieve with the ‘step’ between the nominations. It was important for the teams to find out as much about the hypersoft here as they could, to see how it could fit into a race strategy. Balancing the load between the front and rear tyres, given the quite different demands between the first and third sectors of this circuit, is likely to be a key to success in Russia.
