Singapore GP race quotes: Lotus

Romain Grosjean - DNF: "The race was going pretty well and I think a second or third place finish was a realistic prospect. We had a good strategy pitting under the safety car and we should have finished well, but unfortunately today my engine had other ideas. We lost air pressure and the team tried to fix the problem by topping it up with an additional pit stop, but that didn't work so we had to retire which is never what you want to happen."

Eric Boullier: "Another day of mixed fortunes and commiserations for Romain who had a superb weekend, stymied by a reliability issue in the race. On the other hand, huge congratulations to Kimi for a typical "never-give-up" race carving his way through the field nicely to put the back problems which have affected him all weekend right behind him. Our race strategy worked perfectly today and we were able to jump a number of other cars well."

Ricardo Penteado - Renault: "The team did a great job with the strategy today; getting Kimi from 13th to 3rd on a track you can't overtake on is a real achievement. Unfortunately Romain retired with an engine pneumatic system problem. Air consumption had been inconsistent throughout the race so we pitted him to top the air back up, however the consumption remained high so we were forced to retire the car on the next lap. We'll look at why it happened as it was a brand new engine and put solutions in place to ensure it does not happen again."
