Along with the usual speed, consumption and range readouts, the driver is provided with information about cars on the road ahead as well as on-coming traffic not yet in the field of vision – an innovation BMW claims allows the driver to better respond to varying conditions, especially when travelling in autonomous mode, where a warning is sounded, giving the driver up to seven seconds to take command when a potential accident is detected.
The driver can selection between three drive modes – pure drive, assist and auto - via a control imbedded in the left-hand spoke of the steering wheel. Pure drive provides optimum performance, assist relies heavily on networking solutions to provide the fastest journey time based on real time traffic information and Auto sees the BMW i8 roadster concept take control itself, accelerating, braking and steering independently, without the driver having to intervene.
In the latter mode, the steering wheel lights up in a blue hue, providing a visual cue of the autonomous control. If the car leaves its approved lane a red light signals the driver to take control.
The most striking display, though, is a central panorama unit extending across the top the dashboard from the centre console. Some 110mm high and almost 400mm in width, the large monitor boasts a screen diagonal of 21 inches. Although seemingly obstructive, BMW claims the new display is no higher than the 8.8 inch screen used by the existing i8 coupe.
Upon entering the i8 roadster concept, the panorama unit displays content sourced from BMW’s Open Mobility Cloud via a wireless data connection. The information displayed alters depending on the drive mode that is chosen, allowing, for example, video phone calls, but only in the auto (autonomous) driving mode.
A further development is Air Touch. This new human-machine interfaces provides gesture control for all communication, information and entertainment functions of the panorama display unit, allowing it to be used like a touch screen without the need to actually having to touch it.
Sensors used to control Air Touch are installed in the dashboard. They respond to various hand movements, including a so-called push gesture, which allows occupants to activate icons on the large central display. A second option for carrying out commands is located on the right-hand spoke of the steering wheels. It illuminates when a menu or icon can be activated. A similar button for the passenger is located on the door panel.
