In October 2014, the brand with the four rings proved that piloted driving can even be extended driving at the limit. The Audi RS 7 piloted driving concept completed a lap of the Grand Prix course in Hockenheim without a driver at race speed. To ensure precise orientation on the course with centimetre accuracy, the vehicle made use of specially conditioned GPS data, which is transmitted to the car via the WLAN automotive standard as well as redundantly via high-frequency radio. Simultaneously, 3D cameras monitored the course by video. A computational program compares the information from the images to a data set that is stored in the vehicle.
