2012 Audi R8 GRAND-AM

The Audi R8 GRAND-AM successfully passed its baptism by fire. The new model was fine-tuned at the Daytona race track (Ú.S. state of Florida) during its final test on Tuesday and Wednesday.

Ready for the North American market: The development of the next customer sport race car from Audi Sport customer racing has been completed. The car will be delivered to the first customers by January. The new Audi R8 GRAND-AM is based on the extremely successful Audi R8 LMS that has scored more than 110 victories and 13 titles. From this GT3 race car quattro GmbH developed a vehicle for the Grand Touring class of the GRAND-AM Rolex Sports Car Series in the ÚSA and subjected it to final testing at Daytona.

After track tests in Europe the R8 GRAND-AM that features significant modifications compared to the GT3 race car underwent its final test in the heart of the region where it will be fielded in the future. On the two test days, Frank Stippler completed about 1000 kilometers (600 miles) in the visually conspicuous test car from quattro GmbH that sports a stars-and-stripes design. The famous Daytona International Speedway in the Ú.S. state of Florida with its banked turns served to prepare for the Daytona 24 Hours at which private racing customers will compete with the R8 GRAND AM on January 28th and 29th.

The Audi R8 GRAND-AM clearly differs from the GT3 'sister model' and required a fundamentally new set-up. Downforce, for instance, is drastically lower. About 70 to 80 percent of aerodynamic grip is lost because the GRAND-AM regulations prescribe modified body components. The new front splitter may only protrude from the front contours by 38 millimeters, for example. The front underbody must have a flat design. The rear diffusor corresponds to the production car component, while the standardized rear wing is only 152 centimeters wide and thus 260 millimeters slimmer than the rear wing of the R8 LMS. 'The lower aerodynamic forces also require modified damper characteristics and softer spring rates,' explains Armin Plietsch, Head of Engineering Customer Sport at quattro GmbH. In addition, the regulations prescribe a ride height of 65 millimeters - which is about 10 millimeters more than the minimum in the FIA series.

At Daytona, Audi also familiarized itself with the tires from the series' exclusive tire supplier, Continental. The GTR (for road courses) and GTO (for oval tracks) tire models influence suspension set-ups as well. ABS and traction control, which are standard equipment on the Audi R8 LMS, had to be deactivated for the R8 GRAND-AM. The optimized radiator package that Audi developed for the R8 LMS ultra is also used in the R8 GRAND-AM.

'We successfully tested all the modifications at Daytona,' says Romolo Liebchen, Head of Customer Sport at quattro GmbH. 'With Frank Stippler we developed a sound and solid set-up for our customers and also gathered valuable findings in the endurance tests. The durability of wearing parts and runs at high outside temperatures meet challenging demands. We can now provide our racing customers with concrete advice and reference values for fielding the car.'

The rating of the Audi R8 GRAND AM is still an open issue. By January, a balance of performance is to be achieved between the various vehicles in the GT class. Audi has made one of the 5.2-liter V10 FSI engines used in the Audi R8 GRAND-AM available to the series' engineers for a precise performance analysis. The engine's power output and homologation weight will only be defined once this rating is available.

One of the customer teams for the 2012 season has already been determined. APR Motorsport from Opelika in the Ú.S. state of Alabama will be the first team to field the Audi R8 GRAND-AM. The squad is planning to contest the Daytona 24 Hours and the remainder of the races with its own driver combinations. Negotiations with three other teams are currently in the closing stage. A maximum of four Audi R8 GRAND-AM cars will be delivered for the 2012 season to ensure individual support and coordinated logistics. Audi of America is responsible for sales and support to customers in North America.

American premiere for Audi R8 GRAND-AM

• Debut of new development for the North American market

• Two customer teams to contest entire season

• Both cars classified in 24-hour race at Daytona

Further boost for an attractive scene: the GRAND-AM Rolex Sports Car Series has a new member – the Audi R8 GRAND-AM. Two examples of the powerful 480 hp GT sportscar celebrated their premiere in tough conditions at Daytona. The customer teams APR Motorsport and Oryx Racing were classified at the finish.

Audi Sport customer racing's attractive program is a valuable element richer: the Audi R8 GRAND-AM vitalizes the hard fought North American market in GT racing since January. No less than 44 GT race cars contested the season opener in Florida. The 50th running and anniversary event of the ‘Rolex 24 at Daytona' provided a worthy venue for the debut of the Audi R8 GRAND-AM car. Team APR Motorsport finished in 31st place with its drivers Ian Baas (ÚSA)/Nelson Canache (YV)/Dion von Moltke (ZA)/Dr. Jim Norman (ÚSA)/Emanuele Pirro (I). Oryx Racing came home in 32nd place with Humaid Al Masaood (ÚAE)/Saeed Al Mehairi (ÚAE)/Steven Kane (GB).

At all other GRAND-AM races up to the end of September the race car, newly developed by quattro GmbH, will compete in the Únited States and Canada in the hands of private customer teams. The customer racing car is distributed through Audi of America. Brad Kettler, who has been integrated for many years as engineer in Audi's Le Mans program, has built up a service and logistic structure. As a result, the Audi customers are provided with expert support during race preparation and also during the events.

In addition to the bases in Japan, Australia and China a fourth base is now also created in the ÚSA in order to provide optimum support for the private teams with their cars. Únder these conditions the Audi R8 GRAND-Am has the opportunity of continuing the blossoming success story in the hands of customer teams. The ÚS version was developed using the Audi R8 LMS as basis. This GT3 sportscar has won no less than 118 races and 13 championship titles worldwide since 2009. Its successor – the Audi R8 LMS ultra available from March – will make its debut in a few weeks.
