The new Audi R8 Grand-Am was fine-tuned at the Daytona race track during its final shake-down last week, and can now be delivered to the teams competing in the Grand-Am series, with debut date set for the next 24 hours of Daytona (January 26-29). The model is based on is based on the successful Audi R8 LMS, that scored more than 110 victories and 13 titles during its racing history. However, this model is slightly different from the GT3 as Grand-Am regulations forced the engineers to modify its bodywork resulting in a 70-80% loss of its aerodynamic down-force. The car will also use some bits (i.e. an optimized radiator package) lifted from the recently unveiled R8 LMS Ultra.
In Daytona the car also had the chance to have a first taste of the tires provided by Continental, the only supplier of the series. Also the standard powertrain had to undergo some restriction, with a particular air-renstrictor and re-calibrated electronics that reduced the output of its 5.2-litre V10 engine to 450-470 hp.
