Daniel Ricciardo had some problems with his Red Bull throughout the day, but Force India are looking solid.
Daniel Ricciardo: "We didn't get much running this morning due to an engine issue, but it was okay and we recovered well in the afternoon. The track's always fun here, for a track with so few corners it's very challenging and with the low downforce braking it's very difficult. Obviously we want to be a bit further up, but I think we can chip away at it tomorrow, the Mercedes will be quick, but if we can sneak into the top 5 in qualifying then we'll have a good crack at the race. Getting temperature into the tyres is tricky, especially for the first timed lap."
Sebastian Vettel: "It was quite slippery out on track; this year's cars are down on grip and we have minimum down force in Monza. It was a good day for us, we didn't have any problems and were able to do a lot of laps and test some things. It's important to get Friday right in order to be able to build on that for the rest of the weekend. The tyres mean it should be a one stop race on Sunday, but we will see. I think some struggled to get them to work; there's not so much different between the medium and hard tyres here. I think tomorrow should be better, as it should be warmer and the track will start rubbering in a bit. I felt a bit more in charge of the car today."
Sergio Perez: "Today was a promising start for our weekend and we managed to do everything we had planned. We have good pace already, especially during the long runs, where we look competitive. Now it's just a matter of getting everything right and having a good qualifying position tomorrow to make the most of our strengths."
Nico Hulkenberg: "This morning was quite normal for a Friday, but the afternoon was a bit more difficult and it was not easy to find a nice rhythm. I just didn't find the balance and harmony I was looking for and that showed in the lap times. So we need to dig deep into the data and see what we can improve for tomorrow. Apart from that it was a successful day with the tyre work and collecting the long-run data."
Daniil Kvyat: "It was a busy day today but unfortunately we are not yet where we want to be. With the warm temperatures, it was a bit tricky out there and tyre management wasn't easy. We still need to work on the car balance, which I wasn't very comfortable with today. So we still have some homework to do tonight in order to get the most out of the car for the rest of the weekend."
Jean-Eric Vergne: "I wasn't really happy with the car today. Tonight we'll look at all the data with the engineers with the aim of getting the right solution for tomorrow and as much performance as possible for the rest of the weekend."
Esteban Gutierrez: "In the morning we went through our planned programme. We tried different mechanical set-ups and changed the aero balance on the C33. At the beginning it was ok, but with the modifications that we made at the end of the first free practice I did not have a good feeling. In the afternoon we changed the modifications back again to the ones from the beginning of FP1, and the session was overall ok. I think we can still improve the car a bit further. We are looking into it for tomorrow, and we will also concentrate on the grip evolution."
Adrian Sutil: "It was a good Friday. As I could not run in the first free practice, I was not driving much today. At the beginning it is always difficult to find a good rhthym. In general the second free practice was quite good, but I am not totally satisfied with the balance of the car yet. We have to work on having less understeer. On the other hand, we completed our planned programme without any issues."
