BMW Delivered First BMW i8 Sport Models With Laser Headlights
|   Friday, June 20, 2014
During a ceremony at BMW Welt the first eight BMW i8 were finally delivered. The event marked the debut of the first road car equipped with laser headlights. The BMW i8 enters history not only for the revolutionary plug-in hybrid propulsion technology fitted on a sports car and for the materials used, but also as the first car that takes lighting technology to a new level.

The event was attended by Roland Kr├╝ger, Director of Sales and Marketing for BMW Group Germany, and Dr.
Helmut Schramm, Director of Manufacturing electric cars, BMW Leipzig Factory, and German personalities, such as German presenter Thomas Gottschalk, and actor Thomas Kretschmann.

While the basic version of the BMW i8 is equipped with full LED lights, laser lights are optionally available and provide a double light with a beam of up to 600 m (compared to 300 m for LED). In addition, due to the new laser technology, it is possible to increase the energy efficiency by 30 percent in comparison to the LED lights.

In addition to reduced energy requirements, BMW laser headlights illuminate the road with a significantly higher power, but without heating the surrounding area. Laser diodes are ten times smaller than the conventional light emitting diodes. Thus, they contribute not only to reducing the space required for installation inside the lighthouse, but also the mass.

The size of the reflector surface can be reduced up to ten times in comparison with LED lights. Now, the reflector height was reduced from nine centimeters to less than three centimeters.

A laser light is extremely bright, similar to natural daylight, a positive aspect perceived by the human eye. Through the special lenses, high performance diodes emit a strong beam into the phosphor fluorescent substance inside the headlamp. This substance transforms the beam into a very bright light that is ten times brighter than conventional light sources. Due to their intense and almost ideal beam, the laser diodes have a higher efficiency and the whole system ensures low power consumption. In addition, the glare effect is eliminated by electronic control of the beam using information provided by the front camera system.

Through all its properties, the BMW laser headlights are the ideal light source for a car. They combine superior performance and safety with high efficiency and compact size. The remarkable ray action facilitates efficient lighting and better visibility when driving at night. Consequently, the laser lights ensure a relaxed driving experience that is more comfortable while improving safety in traffic.

The BMW i8 is the first production car in the world that has this innovative lighting technology. In subsequent years other BMW models will be equipped with the laser lights system.

The new BMW i8 is remarkable for using innovative materials too. Similar to the BMW i3, it is based on BMW's LifeDrive structure that combines an aluminum chassis with carbon fiber bodywork.

The expansive use of ultra-light materials, which include, for example, the rear window, chemically reinforced glass similar to that used in mobile phones, ensures a total mass of less than 1500 kg, remarkable for a plug-in hybrid car.
