With qualifying yesterday finishing in wet conditions, the drivers were allowed to start the race on whichever compound they preferred, opening up the possibilities for different strategies still further. A number of drivers and teams maximised these opportunities to the utmost today, especially Sebastian Vettel and Red Bull, who controlled the race. But we also saw some very good strategy calls all the way down the grid, which enabled many drivers to improve on their start positions. Following the uncertain weather earlier in the weekend, this was actually quite a straightforward Belgian Grand Prix, with dry conditions from start to finish and no safety car periods. But Spa remains probably the ultimate test of a Formula One tyre, with its long lap and high energy loadings, so the performance and durability of our tyres after a hard-fought race on one of the most epic tracks in the world were very much in line with our expectations.
