Volkswagen Group has found a solution to foggy front windows that does not involve tiny wires implanted in the glass.
Instead, the German automaker has developed a way to insert a wafer-thin, electrically conductive layer of invisible silver in the laminated glass. The layer can take a current of 400 to 500 watts, which allows the window to warm up quickly and defrost the glass, the automaker said in a statement.
At the bottom section of the glass are filaments that heat the windshield wipers, preventing them from freezing to the glass. VW is offering the new windshield as an option on the Golf, Golf Sportsvan, Tiguan, Sharan, Passat and Passat variant models in Europe. No word on whether it will be offered in North America.
In hot weather, the layer of silver acts as a passive heat shield, reflecting up to 60 percent of the heat, according to Volkswagen.
Prices start at 340 euros, depending on the model.
