What kind of paint does Audi use on their cars? Like have they switched over to ceramic yet?

Read somewhere that Mercedes started using "ceramic paint" on their cars 2003+ and BMW had something similar, but not sure what year it started. Was wondering if Audi uses ceramic paint too.|||Waterborne paint these days. It is a water based paint versus a solvent based paint. Better for the enviroment because Waterborne paints reduce VOC emissions and worker exposure to hazardous air pollutants.|||They use water based paint.
