The teams had their preparation time for qualifying limited by wet weather yesterday morning, so there were still a number of question marks today. As expected we saw a considerable degree of track evolution, with this year’s pole time in Barcelona the fastest-ever since Pirelli came to Formula One in 2011. The teams have quickly got to grips with our latest evolution of the P Zero Orange hard, which should make it easier to maintain the tyres within the optimal working temperature range and so use a wider variety of strategies. With plenty of lateral energy through the rubber, an abrasive surface, and warm temperatures Barcelona is quite challenging for the tyres. We would expect to see three pit stops tomorrow – as was the case last year. The race has never been won from outside the front row, so it will be interesting to see if any drivers can reverse that trend through the use of strategy.
