For the Williams team it was another uneventful session that saw the team continue on their setup programme. Overall it was a very productive day with the team having no reliability issues. In particular the team was able to run their KERS throughout both sessions. Pastor had been focusing on longer runs in his second session so hopefully we may seem some pace from him on Saturday.
