Aston Martin racer Darren Turner still believes the AMR-One has potential, despite a disappointing appearance at the Le Mans 24 Hours.
Both the #009 car and the #007 machine Turner was due to share with Stefan Mucke and Christian Klien retired in the first hour of the French enduro with engine-related problems.
"We changed the water pump pulley from aluminium to steel after we found some cracks in it after Thursday night's qualifying sessions," explained Turner. "Unfortunately this just pushed the problem further down the line.
"In hindsight if we had run with what we had we would've completed more of the race. It's a bitter disappointment to go out so early."
Despite the problems, Turner was encouraged by the handling of the new turbocharged Aston.
"As a team we need to regroup and push on," he added. "The handling characteristics of the car have been impressive, which bodes well for the future of AMR-One. Now we need to focus on continuing the engine development."
