Sam Michael, Technical Director, WilliamsF1: "Mark had a good start and drove a consistent race all afternoon to finish p10, which is where the car is currently at. On Nico's car, we had a problem with a driveshaft and he lost drive, the exact cause of which is not yet known and we will investigate this later. Nico was looking good for a points finish, but it was not to be. Apart from that, we still have some work to do to close the gap to the front."

Mark Webber: "I got a reasonable start and did some of my passing work in the first chicane, some in the second. Early on the first stint I had a good fight with one of the Red Bulls and I managed to get past. Then I tried to stay with Trulli as I expected him to be on a one-stop strategy too, but I couldn't hold the pace because the rear of the car felt quite loose, so I consolidated my position to get the car to the finish."

Nico Rosberg: "One of the driveshafts was damaged at the second chicane. It's unfortunate because we have been running through that chicane for three test days last week and the whole GP weekend and nothing untoward happened. My weekend had been pretty good up until my retirement, so it makes it more difficult to accept a DNF. We need to take some big steps to improve our performance, but we can do this by working together as a team and I think we'll get there very soon."

Mike Janes, Team Leader, F1 Track Support, Cosworth: "Although it was frustrating not to score any points today, this was tempered slightly by achieving our engine performance targets as planned with respect to Mark's engine for this weekend without any major issues. His CA012 has reached the end of its two event life having run to our most aggressive duty to date, while Nico's engine, run to a similar duty, has plenty of performance left in it for Shanghai."
