Audi dynamic steering alters the steering ratio depending on the vehicle speed and simultaneously adjusts the steering torque to match the ratio.
At high motorway speeds, Audi dynamic steering adopts a more indirect steering ratio, eliminating nervousness in the steering and improving straight-line directional stability.
If the vehicle is being driven at low to medium speeds on twisting roads, a more direct ratio is used to increase steering precision and speed up steering response.
During parking the steering has a direct ratio to make manoeuvring easier for the driver. Audi dynamic steering is only available in conjunction with Audi drive select.
