The wheel can be stowed in the center console when in (semi-)autonomous driving mode, opening up new possibilities for the design of vehicle interiors.

Fully integrated FWS by wire steering system

Combined with a mechatronic actuator on the steering gear, it provides completely steer-by-wire functions.
