Sauber joined Marussia and Caterham at the bottom of the timesheets in Friday's practice for the Spanish Grand Prix...
Esteban Gutierrez: "In total, it has been taking me some time to adapt to the track conditions and to the new package. At the moment, I don't feel very confident. I am not very happy with the car's balance. We had some issues with the power unit, so we lost quite a lot of time on track, which makes it more difficult to get a proper feeling for the car. However, we will do our best to sort these things out. We have data from Adrian's car which will help us to analyse the differences between the cars and to find the right balance for tomorrow."
Adrian Sutil: "We definitely made a step forward today. In the morning it was not easy to evaluate things because we had to solve some minor issues. However, I had a good feeling about the potential of our car, and during the afternoon was able to witness this. My fast lap was ok, but I think we can improve in every corner. If we can implement everything tomorrow, we certainly have a good chance to finish tomorrow's qualifying in the top ten. I am satisfied with today's outcome. We still have a lot of work ahead of us, but we are going in the right direction."
Jules Bianchi: "I think we have shown that we have made a good initial step with our updates today. It is never the case that you get everything from them immediately, so there is still plenty of work to do to understand how well they are working and where we can improve. With Max running the previous specification today we will have some interesting information to look through this evening. In simple terms we are closer to the cars ahead and keeping the Caterhams behind us, which is good."
Max Chilton: "It hasn't been an entirely straightforward day for me today and that can be frustrating when we have so many important boxes to tick. The primary focus today was achieving a good comparison between the two different aero specifications. We made good progress this morning so I was able to make use of the developments myself this afternoon. We lost a bit of time early in FP2 because of an engine problem and the afternoon was a little bit stop-start generally. I'm looking forward to evaluating what the new developments can bring."
Kamui Kobayashi: "That was a tough day for us, with lack of grip stopping us get anything good out of the car in either session. We used most of FP1 for aero evaluations, looking at the new parts we've brought here and also starting work on the setup options we have for the weekend ahead, but with the grip issue I really couldn't put a clean lap together in the whole session. It was the same in FP2. The track was a lot hotter than FP1 and it seemed to make the rear worse, but overall I couldn't find a decent laptime on any of the runs. We obviously have a lot of work ahead of us tonight to find a setup direction that will allow us to get back to the performance levels we're targeting, but we've had a few Fridays like this so far this year and we've always come back fighting on Saturday so I know we can be better tomorrow."
Marcus Ericsson: "Like Kamui, for me the low grip levels in both FP1 and FP2 dominated both sessions. I couldn't really push at all because for most of the day the car was switching from oversteer to understeer the whole way round the lap - to be honest it was a bit like driving on ice which is not what we want! For FP2 we made several changes but still had the same issue with grip. The traction levels were also very low and it was difficult applying the power, especially with the car moving around as much as it was. With all of this going on I didn't have a chance to put in a clean quick lap on the mediums, so the final times today are pretty meaningless for us and I'm sure we'll bounce back tomorrow. Even with the handling issues today we've still completed a good amount laps so we have a lot of data to work through and we'll get back to where we want to be."
