Audi is talking excitedly about its new optional headlight technology for the all-new R8, which as mentioned, uses laser spots as the high-beam headlight to supplement the LEDs. These new laser high-beams attain nearly twice the lighting range compared to their purely LED counterparts through the use of high-intensity laser diodes. It was first seen on the Audi R18 e‑tron quattro race car before making its commercial debut on the limited edition 2014 Audi R8 LMX.
In use, you would be able to distinguish these headlights by their faint blue light signature. Each headlight contains one laser module that operates with four high‑intensity laser diodes, a phosphor converter then transforms the blue light into pure white light.
That's about all we can tell you for now, apart from what we've already seen in the spyshot of the car leaked weeks ago. Stay tuned for more news as we head on to the Geneva Motor Show in March.
