I knew about the Q50 going steer-by-wire long ago but didn't know that they went back to conventional... but it seems like they offered it (again) w/model year '18?WetEV said:lorenfb said:LeftieBiker said:I'll bet it uses the same steering rack as the Model 3.
Remember that most all vehicles presently are "drive-by-wire", which means that there's no mechanical connection from the steering
wheel to the steering rack. The system uses an ECU to drive a motor with feedback to control the ratio. This can provide for various
steering ratios, e.g. a sport mode.

The first production vehicle to implement this was the Infiniti Q50., but after negative comments they retrofitted the traditional hydraulic steering.
Is there any production car today that is steer by wire?

I believe steer-by-wire is still the exception and not the norm in currently sold vehicles.
