British GP race quotes: Lotus

Romain Grosjean - 19th: "Towards the end of the race we lost quite a big part of the front wing meaning it became really difficult to drive, so in the end it was best to retire because of safety considerations. We don't know if it was caused by some debris or something to do with the fact that it was a new part; we will be working to find out the root of the problem. Before that my race wasn't going quite to plan and we were suffering with tyre performance. This was related to the front wing issue which started earlier in the race. The safety cars didn't really go our way either so it's a race I'd rather forget. Let's go to Germany and have a better weekend."

Eric Boullier, Team Principal: "The outcome of the race isn't rewarding with the amount of work that has been done by the team recently. Most of the upgrades we brought here seem to be working which is a positive sign, although we did struggle a bit in qualifying to generate good grip from the tyres. Our strategy was great today until the last safety car when we should have called Kimi in to save at least one position and make the podium. Unfortunately, we made the wrong call for which we apologise to Kimi and to the team. This sometimes happens and it isn't easy to manage when you have so many safety car periods. We will be in Germany in a few days' time where we're confident we will be competitive and aiming to make amends."

Alan Permane, Trackside Operations Director: "We have mixed feelings today. We made some good places up during the race but in hindsight, we should have pitted Kimi at the final safety car. It wasn't obvious at the time, but the benefit of hindsight is always enlightening. Romain had a front wing failure near the end of the race, the cause of which we don't know yet. We weren't affected by the tyres issues that we have seen today but warned our drivers to stay clear of the kerb at Turn 4 as there was a suspicion it might be the cause. Despite not being as good as it could have been, it was a better weekend for us than the last two. Further upgrades we have coming for Germany mean we fight on."
