ECO mode is designed for economy by reducing the accelerator response time. Also handy when you are on the trails and looking for a bit more throttle control when crawling.
Ultimate Mode offers 9 sensitivity levels, this allows the driver to tune the controller to the desired level of sensitivity.Choose level 9 and grip the steering wheel tight or hit level 1 for a gentle smooth acceleration.
Automatic control mode automatically selects the sensitivity level based on pedal pressure. If you are in traffic and accelerating gently the iDRIVE will automatically choose a reduced level of throttle response.
