The Subaru Legacy has been in continuous production since 1989, evolving through multiple generations with steadily improving glass technology. Earlier models carry straightforward laminated windscreens, while later variants from the mid-2010s onwards feature rain sensors, heated windscreens, and acoustic interlayers depending on trim and specification.
From around 2013–2014 onwards, many Legacy models began incorporating Subaru's EyeSight driver-assistance system, which uses dual stereo cameras mounted at the top of the windscreen. These camera-equipped variants require static recalibration after windscreen replacement, adding to the technician's time on the job but not extending your drive-away window.
