United States GP: Lotus Friday quotes

Romain Grosjean - 15th/13th: "The most noticeable thing about the circuit at this stage is the lack of grip; it's really, really slippery out there. The layout itself looks very nice but we're a long way off being able to push the car anywhere near the limit, particularly through Turns 7-9 and towards the end at Turn 19 where it's tricky to predict how the car will behave. The good thing is that the car felt comfortable on long runs with the hard tyre so we have a good starting point, but there is still a little bit of work to do with the mediums. We still have tomorrow morning and I think the track will continue to improve right until the end of the weekend, so qualifying will be interesting for sure."

Alan Permane, Trackside Operations Director: "Despite being an all-new track, it's been a fairly normal Friday for us. The morning session delivered the expected low levels of grip with the surface improving hugely later on making any comparison tests very difficult. This meant we concentrated on keeping the cars balanced and spending as much time out on track as we could. FP2 was a mix of setting the cars up and then carrying out high fuel work, however both struggled to get a clear lap on the medium tyres. Neither driver was particularly happy with their set-up so we've got a little bit of work to do. Our high fuel pace looks okay, and we're confident we can deliver more on low fuel tomorrow."
