In April 2014 BMW said that the future lighting technology for their automobiles will be OLED, and that BMW expects to start selling cars with OLED lighting within 3 years. The respected Car and Driver publication now says that the 2016 M2 car will be the first one to adopt those OLED tail lights.
I'm actually a bit skeptical on that - it seems too soon for BMW to release OLEDs in a car, and even according to BMW, they estimated it won't happen before 2017. But maybe Car and Driver knows more than they can reveal, it'll sure be a nice surprise to see the first ever OLED lighting car next year.
In January 2015 BMW demonstrated a new concept car, the M4 Concept Iconic Lights that features a new OLED-based tail light (with OLEDs made by OSRAM). The rearlights use yellow and red OLED lighting panels arranged in a 3D structure. During the car's unveiling, BMW said that they aim to launch a production model with OLEDs in the "near future".
