Audi scored yet another major success in the development of piloted driving: Before the season finale of the Deutsche Tourenwagen Masters (DTM), the latest technology pioneer was running up to its physical limit, with no driver. It took the Audi RS 7 piloted driving concept just slightly over two minutes to complete a lap on the Grand Prix track in Hockenheim – piloted with high precision and accuracy to within centimeters.
“The top performance by the Audi RS 7 today substantiates the skills of our development team with regard to piloted driving at Audi,” said Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development at AUDI AG. “The derivations from series production, particularly in terms of precision and performance, are of great value for our further development steps.”
For orientation on the track, the technology pioneer uses specially corrected GPS signals. This GPS data is transmitted to the vehicle via WiFi according to the automotive standard and redundantly via high-frequency radio. In parallel to this, 3D cameras in the car film the track, and a computer program compares the cameras’ image information against a data set stored on board. This is what makes it possible for the technology pioneer to orient itself on the track within centimeters.
Piloted driving is one of the most important development fields at Audi: The first successful developments were achieved ten years ago. The test results continually flow into series development. The latest test runs at the physical limit are providing the Audi engineers with insights for the development of automatic avoidance functions in critical driving situations, for example.
Driver assistance systems from Audi are already making driving more relaxed and better controlled. These systems’ highest level of development can be experienced in the updated Audi A6* and Audi A7 Sportback* model series. The offerings include Audi side assist, Audi active lane assist, and adaptive cruise control with StopGo function including Audi pre sense front.
Experts from Volkswagen Group Research, the Electronics Research Laboratory (ERL) and Stanford University (both in California) are supporting Audi as partners in the further development of piloted systems.

Fuel consumption of the models named above:
Combined fuel consumption in l/100 km: 9.6 – 4.2 (24.5 – 56.0 US mpg)**;
Combined CO2 emissions in g/km: 224 – 109 (360.5 – 175.4 g/mi)**
Audi A7 Sportback:
Combined fuel consumption in l/100 km: 9.5 – 4.7 (24.8 – 50.0 US mpg)**;
Combined CO2 emissions in g/km: 221 – 122 (355.7 – 196.3 g/mi)**
**The fuel consumption and the CO2 emissions of a vehicle vary due to the choice of wheels and tires. They not only depend on the efficient utilization of the fuel by the vehicle, but are also influenced by driving behavior and other non-technical factors.
