Clearly, an aftermarket replacement. Looks to be spec, though, since it is "acoustic HUD". Neither of our Stingers has HUD, but both windshields are sourced from "Saint-Gobain Sekurit", the very old glass company founded in Paris in the 17th century with plants in a bunch of places. You can see the same info on the two front doors glass, which are also acoustic, as is the hatch window. Probably the sunroof glass is also from the same company, but I can't see an info marker on mine.
