Both Williams F1 drivers were again very busy trying out new parts on their cars but again the team experienced a KERS failure. The team will however equip both cars with KERS for the remainder of the weekend after having left out KERS from Rubens Barrichello's car at the German GP.
Sam Michael, Technical Director:
"We tested different diffusers and a new rear wing with Rubens today and new bodywork and a revised suspension system on Pastor’s car. Although we had a KERS issue in P1, both cars will have KERS for qualifying and we will have the new rear wing for Pastor’s car in time for tomorrow’s last practice session."
Rubens Barrichello, FW33‐04 CA420:
FP1: 1:25.836 (14th) 24 laps
FP2: 1:23.679 (13th) 34 laps
"We tested a lot of things today. We had to run without KERS in the morning session because of a small problem but we reinstated it for the afternoon and it was fine. The car has improved a little bit, but P13 isn’t where we want to be and it’s going to be tough to break into Q3 tomorrow. Our goal today was to focus on set-up for the race as I think points are achievable here."
Pastor Maldonado, FW33‐02 CA325:
FP1: 1:26.124 (18th) 25 laps
FP2: 1:24.181 (15th) 39 laps
"We brought new parts to Hungary which we spent today testing. I was trying out a new cooling system and I have an updated rear wing coming tomorrow that was working well on the other car. I’ll be working hard tonight with my engineers to improve the car. We’ve got plenty to do in order to have a good race."
