In a world-first, laser headlights developed by BMW are now available as an option for a series-produced model. They boast three times the light intensity and double the range of conventional headlights, as well as extremely low energy consumption. Tiny laser diodes generate a very bright, white light that is pleasant on the eye. Compared to LED headlights, which are already highly efficient, they cut energy usage by at least a further 50 per cent. Laser light generates 170 lumens per watt compared to around 100 lumens in the case of LED lighting, a little over 80 for xenon headlights and around 20 for halogen lights. Laser light is monochromatic, which means the light waves all have the same length and a constant phase difference. That results in a near-parallel, high-luminance beam which enables high-precision adjustment and a range of almost 600 meters. And it all comes with minimal demands on space because laser diodes are 10 times smaller than LEDs. Light tracking, moreover, ensures the road is optimally lit even if it runs through hilly terrain, for example. Incidentally, this laser light is entirely safe: what are originally blue laser beams emitted by the diodes are first directed to a layer of phosphorus that turns them into harmless light resembling natural daylight. The resulting high-contrast illumination of the road makes for fatigue-free and safe driving after dark.

The interior of the BMW i8 conveys sportiness, dynamics and lightness. Distinct driver orientation and a modern cockpit design characterize the sports car of the future. All data required for driving such as speed, range and state of charge are shown on the instrument display in three-dimensional form. Familiar from other BMW models, the central control display on the instrument panel provides a representation of all further vehicle functions, including the extensive BMW Connected Drive services, which have been especially adapted to suit the demands of the plug-in hybrid technology featured in the BMW i8.
