In other words: the GT3 race car that was the second-weakest in the field due to the regulations won the race thanks to its above-average concept. Thus, in the engine output ranking in the SP9 class, the Audi R8 LMS was in the last but one spot at the Nürburgring. The rating of the race car, which serves to put all competitors on a similar lap time level, results in a variation: on the roller dynamometer, the V10 engine produces merely 487 horsepower at the Nürburgring on account of the mandatory air restrictor, while the production model delivers 27 percent more output, that is 620 horsepower. The power-plant in the winning car had already run for 5,000 kilometers before the event at the Nürburgring began.
With service intervals of 10,000 kilometers and rebuild intervals of 20,000 kilometers, the customer racing car makes particularly economical operation possible for the teams. The V10 engine is even almost completely production-based. The quality of the lightweight design is excellent as well: the race car tips the scales at merely 1,235 kilograms, but has to weigh 1,310 kilograms in the Nürburgring 24 Hours due to the regulations. The ASF multi-material chassis of aluminum and CFRP is produced at the same manufacturing facility as the production model, at Böllinger Höfe of Audi’s Neckarsulm site. However, the greatest benefit to our worldwide customers is the durability of our engineering design.” The production-based GT3 race car shares 50 percent of its components with the production model. “In our strategic commitments, we definitely rely on ‘used cars’ as well and demonstrate the success that can be achieved with them.
“This statistic is not only a nice success for Audi Sport customer racing, but also sends a message to our customers,” says Chris Reinke, Head of Audi Sport customer racing.
