Belgium preview quotes: Williams

"The work everyone at the factory is putting in should help us out in Spa. We're not going to make a huge jump, but we'll definitely be heading in the right direction. I'm really looking forward to the Belgian Grand Prix because Spa is an amazing race track. It will be difficult to score points there, but you can never predict what will happen somewhere like Spa, so we'll have to wait and see."

Kazuki Nakajima: "It's going to be the first time I've driven a Formula One car around Spa, so my first priority will be to learn the circuit and to find out how the car behaves on this track. I have, of course, driven Spa while racing in GP2 so know what a great racing track it is. In fact, it's probably one of the greatest tracks on the calendar so I'm really looking forward to taking my FW30 out and doing that first lap!"

Sam Michael, Technical Director: "Spa is one of the greatest tracks we visit. The circuit is steeped in history, with one of its most prolific characteristics being its fantastic corners, created by some significant undulations over the course of the lap. It's a real challenge for the drivers to put in a perfect lap, on what is the longest on the calendar at seven kilometres.

"Spa is a fairly fluid track, with the corners flowing smoothly from one to another. As they are either medium or high speed, good car stability is a pre-requisite, and mistakes made in the early part of the lap are difficult to recover from. A car that can withstand some kerb-riding is also important to get through the Bus Stop chicane quickly.

"Weather is at its most unpredictable in Spa. The mountains in the area create their own micro-climate and small bursts of rain can appear on one part of the circuit and not on the others, which makes tyre choice an additional challenge! Strategists usually adopt a one or two stop approach for Belgium and Bridgestone will take the medium and hard tyre compounds."
