Banbury driver Darren Turner (left) teamed with Tomas Enge, who was driving with a broken hand, to finish second in the GT1 class at the Portland Grand Prix on Saturday in the Banbury-built Aston Martin DBR9.

Their teammates Pedro Lamy and Stephane Sarrazin drove the second DBR9 to a fourth-place finish.

George Howard-Chappell, team principal of Aston Martin Racing, said: "We had tough conditions, given the extreme heat, but I'm proud of the second-place finish and the team's collective effort.

"We need to keep working hard to find more performance.

"Even with the balance of performance' that is part of GT1 it is a handicap-based class we're still not as competitive as we should be.

"We'll go back and make a more detailed analysis of our cars and see what we can do."

Czech driver Enge said: "The first corner is really tight and some of the prototypes came together.

"The car in front of me braked sharply and I hit the back of it, but luckily it didn't affect the car and I came out of the corner in second.

"Pedro was behind me and I knew that he was quicker so I let him past and managed to do very consistent laps for the rest of my stint.

"I'm happy that I was able to drive with my broken hand and score points.

"I want to thank Andrea (Piccini) because he really helped us to set the car up earlier in the week."

Turner said: "I'm a bit surprised we are second as we were quite far behind, but I think they had a problem in the pits.

"That opened the door for us. Tomas had a great start in the car and first stint.

"It is a shame that Andrea didn't get to drive, but it was good to work with him again."

Victory went to Oliver Gavin and Olivier Berettaz who notched up Corvette Racing's 50th victory. Ron Fellows and Johnny O'Connell finished third in a second Compuware Corvette C6.R.
