#007 Aston Martin, Le Mans 2011Aston Martin Racing's technical director George Howard-Chappell says the very best the team can expect at this stage in the AMR-One's development is to get a finish in this weekend's Le Mans 24 Hours.

The pair of AMR-One prototypes have endured a troubled birth, and despite showing better reliability at Le Mans they only managed to qualify 22nd and 25th, among the LMP2 runners.

"Predominantly our problems have been engine-related," Howard-Chappell tosaid. "That's starting to come together now, but it's going to take a bit longer. Ultimately it's a three-year program and we're a few months in, so it'll take some time to get on our feet and be really competitive.

"We're developing the car as we're racing so we'll run it as long as we can. If we can get one to the end we'll be thrilled."
