D he starting point is a dream for every technician:' We started with the cockpit for the Porsche 918 Spyder with a blank sheet of paper, 'beamed Porsche electronics developer Rolf Hartmann. Regardless of company traditions, the task was to develop ideal display and control elements for the hybrid concept car presented in Geneva. Still not an easy undertaking, because after all, the driver should be able to keep an eye on the interaction between electric and petrol drive and to operate extensive comfort and assistance systems with as little distraction as possible.

Porsche 918 Spyder: Novelty Operating system

Hartmann's team was the first to clear out the steering wheel in the Porsche 918 Spyder. All buttons are used exclusively for driving functions such as lights, windshield wipers, gear selection or hybrid mode. Multimedia applications such as the radio or telephone were banned from driving. The three round instruments, of which only the central tachometer has a conventional pointer, are all about driving.

The additional displays on the right and left consist of TFT displays, to which a three-dimensional scale on the edge should give the quality of noble wristwatches. Thanks to high-resolution XVGA displays, the virtual pointers promise to appear as real as their printed colleagues from the driver's seat. In addition, further functions can be displayed if required.

An electronic co-pilot could have Porsche 918 Spyder drivers display braking points on racetracks or on public roads the number of meters in which an overtaking ban was lifted. The navigation device provides the necessary information about curve radii and traffic signs.

Operating system in the Porsche 918 Spyder works via touchscreen

In the Porsche 918 Spyder, the route guide itself is operated via a huge touchscreen that takes up most of the center console. The black panel monitor not only looks classy, ​​thanks to the flexible assignment of a wide variety of functions, the center console has two rotary controls. The sensitive surface of the capacitive display allows you to search for MP3 albums, dial phone numbers or fine-tune the ventilation with the snap of your fingers, just like on the iPhone.

The actual navigation monitor, however, does not react to finger pointing. For optimal readability, it was placed very high and therefore outside of reach. The suitability forTomorrow's electric vehicles, however, have additional functions such as the range display, which darkens the part of the map that can no longer be accessed using battery power and marks charging stations.

Control system in Continental study allows changes to be made

The Continental study 'Simplify Your Drive' is also completely on the display. With the converted VW Passat CC, the driver has the option of changing the set-up of the entire vehicle at the push of a button. Depending on whether you want to drive in a sporty or fuel-efficient manner, the chassis, engine control or automatic transmission change.

Since the Conti technicians replaced the entire instrument panel with a screen, different displays can be displayed depending on the driving mode. If the driver goes for sport, he looks at a central rev counter and a display of the lateral acceleration. If he opts for Eco, he receives recommendations for fuel-efficient driving.

Any other type of recording would also be possible, depending on your taste: basic information reduced to the bare essentials or instruments in a nostalgic look. Displays give their developers complete freedom - just like a blank sheet of paper.
