Audi's CEO said that the Germany automaker is working on a new A8 generation, to launch in 2017. The new A8 will sport several new technologies (Such as piloted-driving) and also a new design - specifically OLED taillights and OLED displays for the infotainment system.
A couple of weeks ago Audi unveiled the 2016 TT RS, which sports (optional, it seems) OLED taillights.
In 2015, Audi demonstrated a luxury electric crossover concept car, the e-tron quattro, that uses an all-OLED interface. The concept used four different OLED displays, with the center console OLED a flexible OLED already shown in the Audi Prologue concept. That display (produced by Samsung Display) was 8.9 x 5.6 inch in size and featured a resolution of 2560x1600 (287 PPI).
