Nico Hulkenberg is confident that Force India can improve further despite posting encouraging pace during Friday practice for the Italian Grand Prix.
Hulkenberg and team-mate Sergio Perez claimed fourth and five in both sessions at Monza, with the former ahead in the morning and the latter edging in front during the afternoon running.
"That’s not bad at all," said Hulkenberg. "The car had quite good pace today and we collected a lot of information about the tyres on the long runs.
"We lost a little bit of track time when I had to cut short a run in FP1 and return to the garage, but in the end it wasn’t a problem because we got nice long runs done on both tyre compounds.
"We were also able to test all the new items we wanted to try out, which was very positive, and now we’re just going to do the usual tweaking overnight to get even more out of the car and improve the balance further."
Perez said that he struggled with a few aspects of the car and was quick to play down Force India's speed.
"I’m still not completely comfortable with a few things – we had a change of brake pad material ahead of the first session and it was difficult at first, but we built up into it and set a really good lap time on the Option tyres," he said.
"I feel there’s potential for even more to come and that we can make further improvements to the balance. To be P4 and P5 in these practice sessions is encouraging, although we can’t read too much into it because we don’t know what the other teams were doing in their programmes."
