Belgium 2013 preview quotes: Pirelli

Before the mid-season break, the Formula One teams visited the slowest permanent track on the calendar: the Hungaroring. Now they head to one of the quickest of all: Spa-Francorchamps, in the foothills of the Ardennes. Pirelli is bringing the P Zero Orange hard and P Zero White medium tyres: the two hardest compounds in the range. These are perfectly suited to the high-energy demands of the circuit, with its rapid corners and fast compressions such as the legendary Eau Rouge. One of the key characteristics of Spa is its variable weather conditions, which means that the Cinturato Green intermediate tyres and Cinturato Blue full wet tyres are also likely to be called into play over the course of the weekend.

Paul Hembery: "Spa is not only an epic circuit, but also one of the biggest challenges for our tyres all year. Mostly this is because of the very high-energy loads that go all the way through the tyres, both vertically – due to the big compressions such as Eau Rouge – and also laterally at fast corners like Blanchimont. Often, the tyres are subjected to forces acting in different directions at the same time, which increases the work still further. So looking after the tyres is very important, particularly as it's such a long lap. This means that there are a very wide variety of possible strategies available at Spa as well, with plenty of time to be won and lost if the right tactics are chosen. However, any strategy has to be very flexible, because it's the changing weather that often makes Spa such a fascinating race. The conditions can change extremely quickly, which then makes how the teams use the intermediate and wet tyres the key to success – as we have seen so often in the past. Both our wet-weather tyres have proved their performance over previous races; with the intermediate tyre in particular showing how well suited it is even to inconsistent and drying conditions. There are plenty of overtaking opportunities, and the blend of performance and durability offered by our nominated tyres should maximise those chances this weekend."

Jean Alesi: "Spa is a circuit that everyone talks about and over the years I've not heard anybody say anything apart from the fact that it is awesome. It's so fast and so challenging, but one of the key characteristics is the fact that it's very long. So it's never monotonous, as you do very few laps compared to other tracks. Managing the tyres takes a special skill: there are lots of fast corners and the length of the track as well as the variable temperatures mean that your tyres can actually cool down after the first part of the circuit. But in qualifying, if you start off with your tyres too warm, then you won't get the maximum performance from them throughout the entire length of the lap. There's a huge amount of variation possible in terms of set-up as well: some teams add downforce to get more grip in the mid part of the lap, and that will also have an effect on how the tyres work. Probably the most important characteristic is the high possibility of rainfall. You can have a completely dry corner and then a fully wet track a few corners later. Underneath the water though, the surface is quite abrasive and offers good grip, so you can still drive. The bigger problem is the sudden rivers of water that run across the track in a zigzag shape: you've got to know where they are, so that the aquaplaning doesn't catch you out. There's also a lot of spray at Spa when it rains, which makes visibility very difficult in wet conditions."
