CoCar NextGen is a pioneering research vehicle for automated and connected driving. Equipped with various high-end sensors, high-performance hardware, and modern networking components, the Audi A6 Avant plug-in hybrid was built independently by the FZI. The modular design enables it to be used for a wide range of applications and research in new mobility concepts. For the first time, the vehicle is not only designed for special test fields but is also approved for all German roads for carrying out test, measurement, and trial drives. The integration of the smart infrastructure of the Test Area Autonomous Driving Baden-Württemberg (TAF BW) in particular offers interesting application scenarios. The range of applications covers freeway sections, state and federal roads as well as complex urban mixed traffic with bicycles and pedestrians, traffic-calmed areas and parking garages. This enables the FZI and interested companies to test cutting-edge research results directly in reality, research new approaches, and further develop automated driving software. The extensive equipment of CoCar NextGen is unique. This includes a comprehensive camera, radar, and LiDAR setup connected to a powerful server. A sophisticated energy system with a battery allows emission-free development operation for several hours.
