Audi has taken its second straight 1-2 finish in the American Le Mans Series after Lucas Luhr and Marco Werner took victory at Road America.
The pair, who had started the four-hour race from pole position, came home ahead of the sister R10 TDi of Marcel Fassler and Emanuele Pirro despite a range of caution periods which meant the two diesel-powered cars were unable to open up an advantage over the chasing LMP2 pack.
The lead changed eleven times over the course of the race before the two Audi R10 TDI cars prevailed in the final stages of the race.
Indeed, Werner left it late to take the win in the #2 car as he overtook the two leading Acuras on the long start-finish straight just six laps before the end of the race to take the win.
"A beautiful 50th race!” he said. “The race was not easy, especially after the penultimate restart with the two Acuras in front of me. Behind these cars we lost a lot of down force, so it was incredibly difficult to close the gap to them. Once I even went off the track. At the end it worked well.
“Thanks to Audi TDi Power we got the Acuras on the straights. It was a nice race, I spent a lot of time in the car, it was a lot of fun.”
Fassler also used the torque advantage of the diesel engine to squeeze into second place on the penultimate lap to secure a fine podium finish on his debut in the car.
"This was a very special race for me,” he said. “The final restart was unbelievable. It was pretty close between Brabham and the wall. But I said to myself: Now or never! It worked out. I am very happy that I was able to give the second place to the team. It ran very well from the beginning, I am satisfied.
“Generally speaking, the atmosphere at Audi and in the American Le Mans Series is perfect.”
