Despite not finishing the city street race in Detroit, the two German Audi "factory" drivers Lucas Luhr and Marco Werner have already clinched the Drivers’ title in the LM P1 class of the American Le Mans Series.
 
The title chase was decided as their teammates Marcel Fässler and Emanuele Pirro, who had originally won the LM P1 class on the "Belle Isle Street Circuit", were excluded after the race. At Technical Scrutineering, the #1 Audi R10 TDI was found to be 2.5 kilograms under the requested 925-kilogram weight limit. Following contact with another car during the morning warm-up session, a spare nose had been fitted which was prepared for both cars, not specifically set-up for the #1 car.
 
This is the third LM P1 title in the American Le Mans Series for Marco Werner (42) following his Championship wins in 2003 and 2004. It is the fourth win for Lucas Luhr (29) following his successes in 2002, 2003 and 2006 – however it is his first in the LM P1 category. Luhr has also become the first driver ever in the history of the U.S. sportscar series to clinch the title in three different categories: GT2, LM P2 and now LM P1.
 
"Of course we would have prefered to have won the title under different circumstances," said Luhr and Werner. "But with seven consecutive victories already this season we certainly feel we have earned the title."
 
Before the last two races at Road Atlanta (4 October) and Laguna Seca (18 October) the two Germans hold a 66-point lead over Emanuele Pirro and are 68 points clear of Clint and Jon Field who were awarded the LM P1 class victory in Detroit. Only 55 points remain available in the final two races.
