Brazilian GP: Lotus Friday quotes

Romain Grosjean - 7th/9th: "It was a very hot and sunny day which wasn't so easy for the tyres as it was difficult to get them to work properly so we struggled a little bit. Speed was not especially easy to find today, but we ran through our normal programme with a little bit of focus on a wet set-up as we know there's rain forecast for Sunday. We only ran a little with the 2013 tyres in the morning; my initial impression is that they feel a bit better and you can notice they have a different construction. Our long run pace was good so let's see what we can do tomorrow."

Alan Permane, Trackside Operations Director: "We've had an encouraging start to the weekend. Although Kimi's track time in FP1 was restricted, Romain completed some interesting back-to-back comparison runs with Pirelli's 2013 development tyre which looks to be a few tenths quicker than the current configuration even on this year's car. Kimi had some catching up to do in the afternoon and struggled initially on the prime tyres, but with a few balance tweaks to accommodate the soaring track temperatures and his engine now running as it should he settled down to put in some decent runs. The track temperature was around ten degrees higher than in the morning - one of the hottest Friday's we've seen all year in fact - and therefore yielded less grip. Despite this however, our long run pace with Romain looked very competitive. We also ran differing setups in anticipation of a potentially dry qualifying, wet race scenario, so there's a lot of data to look at overnight but overall we're pretty pleased."
