This A7 comes with Audi’s standard long-range forward radar, currently used for adaptive cruise control, but also features two rear-facing and two side-facing radar sensors. A laser scanner, or LIDAR, behind the grille serves as a redundant sensor to help the radar with solid-object detection. A 3D camera also looks forward, while four smaller cameras monitor the front and rear views from the corners of the car.
The information from all these sensors and the car's GPS location get processed by an onboard computer, which can control braking, acceleration and steering.
