Paul Williams on the features of the weekend in Spa

      Before the Belgian Grand Prix, Williams' chief race engineer Paul Williams spoke about the factors that could influence the weekend's proceedings…

      Question: What are the main technical challenges of the Spa circuit?

      Paul Williams: Spa is one of the most challenging and diverse circuits, combining long straights with fast and slow corners. The car needs to be quick on the straights but also handle sharp direction changes well. In the famous Eau Rouge, the height and travel of the suspension need to be precisely tuned. Additionally, the weather always remains unpredictable – rain can come at any moment during this Grand Prix.

      Question: How will the 2026 regulations affect the approach to the weekend?

      Paul Williams: Spa is the most energy-consuming circuit we've seen this year. Approaching Eau Rouge, you can change your trajectory; in 2026, five speed limit zones were added, and all of them remain active in wet conditions.

      Question: What strategic considerations should be taken into account during the race?

      Paul Williams: Spa is the second easiest circuit this year for overtaking, but the ability to conserve battery charge will be crucial. This shifts the balance of priorities towards the race. It is expected that the race will be run with one pit stop – and the main question will be which tires to start on – Medium or Soft.

      Moreover, there is a high likelihood of a safety car deployment at Spa, and the weather often changes. Teams need to react quickly to changing conditions, which will play a very important role.
