Bahrain Sunday quotes: Marussia

Charles Pic - DNF: "Naturally I am disappointed, as the race was tough but I was quite happy with the car and managing the tyre wear quite well. Despite the challenging track conditions I was still able to push and I think we were sitting quite well versus the pace of the Caterhams. Unfortunately on lap 24 I had a problem with the Air Valve System and I had no option but to retire the car, which is frustrating for me and the team as they have worked very hard to keep us moving forward here all weekend. As we head to Europe now I have to be pleased with the opening few races in general, but we need to be focused now on improvements for Spain. "

John Booth, Team Principal: "On a positive note, in today's race we saw a continuation of Charles' increasingly strong form and consolidation of his good work from yesterday. It's a real shame that the as yet undiagnosed AVS problem on the engine forced an early retirement during a period of the race where Charles was very competitive with respect to the cars that he was racing. Timo was also beset by the same engine issue and we'll work hard with Cosworth in the next few days to understand the causes of these problems. Unfortunately, our slightly bigger issue has been with the handling characteristics of Timo's car, which came into play from Saturday morning onwards. We have to identify and properly understand the problems that he has been experiencing with the car. Fortunately the Mugello test in one week's time will provide us with some opportunity to iron out these issues away from the pressures of a race weekend. I would like to take this opportunity to commend the team on a job very well done throughout the first four races, which have each brought their own unique challenges. We leave the opening long haul leg behind as a much stronger team and with plenty of cause for optimism for the start of the European season."
