   I can’t imagine polycarbonate being used extensively in auto windows. It is just to soft and subject to scratching. Corning developed Gorilla Glass for cars years ago, and now the weight issue has become important enough to make it viable. The current formulation of Gorilla glass is so strong that two thin layers can sandwich a tough plastic layer between them and still provide the strength, scratch resistance, and sound attenuation.

   “The i8 will be the world’s first volume-produced vehicle to be equipped with chemically hardened glass or Gorilla Glass as it’s called in the smartphone world. It will be used to separate the passenger compartment and boot of the i8 and is comprised of two layers, each 0.7 millimeters thick with acoustic sheeting between.

   This way, in addition to excellent acoustic properties, a further advantage of this solution is weight savings of around 50 per cent compared with conventional laminated glass. See: http://www.autoevolution.com/news/bmw-s-i8-will-be-the-first-car-in-the-world-to-use-gorilla-glass-64587.html
