Sauber announced the hiring of long time JordanForce India Technical Director, James Key. With Keys Experience in resource limited teams and Rampfs desire to decrease his involvement with the team, this makes a lot of sense for the Swiss outfit.
On the track, a revised rear wing with flicked up edges was the main development. The revised wing tips should reduce the downforce and hence drag the wing creates. For greater straightline speed at the cost of grip in the turns. Additionally the team ran with the slotted rear wing, this was kept well hidden the team putting a board over the top and rear of the wign as it arrived in the pits. Lastly the periscope cooling outlets seen in Jerez were replaced by a louvered panel durign some runs.
