Never scratch again! Which driver does not hate the morning ice-scraping in freezing temperatures? First time, a fog- and ice-proof car window have now Volkswagen and Audi is developing jointly with the Fraunhofer Institute. Unlike heated discs thanks to the physics principle arises only no ice – even at minus 18 degrees Celsius. The secret is innovation in a wafer-thin, transparent layer of indium tin oxide that is applied to the glass pane.


The conductive “Low E coating” protects the glass from cooling down, so the water does not condense on the outside or freezes. But a drawback remains:
Weather conditions such as clouds, humidity and wind play a significant role and influence of the discs.


Therefore, the ‘Low E coating’ the ice not completely prevented.
