Audi boss Dr Wolfgang Ullrich was left ruing a wrong tyre call at the Nurburgring on Sunday, something that cost his drivers' any chance what-so-ever of fighting for the victory.
Audi was looking good heading into the race and after a somewhat controversial qualifying 'his' drivers all but locked out the top-five, with Tom Kristensen on pole followed by Mike Rockenfeller and Martin Tomczyk, in second and third and Mattias Ekström in fifth.
At the start though, Audi gambled on rain and switched most of its drivers' to wets. But when the situation then changed before the start, it was just a question of damage limitation.
"Of course, considering the grid positions we had, the result is very disappointing. As the saying goes among skiers, we 'used the wrong wax' and that was a truly major mistake," Ullrich conceded. "We relied on the information from our meteorologists, with whom we've been working for a very long time, that heavy rain would be setting in immediately after the start.
"For such conditions, rain tyres would certainly have been the only right choice. But then, during the formation lap, we were informed that the rain would be passing by and there would only be a few drops.
"Then we took the right decision to immediately call our two most important cars back into the pit lane, to put them back on slicks and to start behind the field from the pit lane. We thus minimised our time loss and managed to defend the lead in the championship. But we were no longer able to fight for victory that way.
"You don't have a lot of time for this tyre decision process. Once the decision has been made, you have to stick with it. After that, it was only a matter of keeping the damage limited.
"Later on, we tried to keep the speed as consistent as possible. Towards the end, the field came together again because of the rain and there was some more good action. Even though the result wasn't optimal for us, I am happy that the spectators got to see a great race."
Audi Sport Team Abt Sportsline director Hans-Jürgen Abt meanwhile was also frustrated with how things turned out, although he defended the weather forecasters.
