2019 Audi A6 Technology – Video
Even more comfort, poise and safety on long and short journeys – the new A6 with new and refined driver assistance systems sets new standards in the luxury class. These include the parking pilot and the garage pilot, which are set to extend the range of equipment during the course of the year: They autonomously maneuver the Sedan into and out of a parking space or garage. The driver can get out of the car before activating and monitoring the process using the myAudi app on their smartphone. To do so, the driver must continuously hold down the relevant function key.
The parking pilot and the garage pilot form part of the Park assist package, one of three packages. The City assist package includes features such as the new crossing assist. The Tour assist package comes with the adaptive cruise assist, which supplements the adaptive cruise control by means of gentle steering intervention to keep the vehicle in lane, and the efficiency assist, which promotes an economical driving style.
Behind the extensive assist systems lies a high-tech module from Audi: the central driver assistance controller (zFAS). It calculates continuously a detailed model of the environment from a fusion of sensor data. Depending on equipment, the sensor set includes up to five radar sensors, five cameras, twelve ultrasonic sensors as well as a laser scanner – another major innovation.
The dynamic all-wheel steering is a key component in this agility and maneuverability. It combines direct, sporty steering response with unshakable stability, resolving this classic conflict of aims. Depending on the speed, the steering ratio varies between 9.5:1 and 16.5:1. This is thanks to a strain wave gearing at the front. At the rear axle, a spindle drive turns the wheels as much as 5 degrees. At low speed, the wheels steer in the opposite direction to the front wheels, thus enhancing the agility of the A6 and reducing its turning circle by up to one meters (3.6 ft) to 11.1 meters (36.4 ft). All of which makes maneuvering easy despite the almost five meter (16.4 ft) exterior length of the large Sedan. At high speed the wheels turn in the same direction, thus optimizing stability when traveling in a straight line or changing lanes. Thus the A6 not only offers the driver smooth straight-line stability at high speed. Passengers also enjoy more comfort since the steering movements seem much softer on the rear seats.
