2010 GMC Terrain: Double-paned Side Glass
September 20, 2010
Here's one reason our 2010 GMC Terrain is rather quiet (70 dB at a 70 mph cruise): Laminated double-pane side glass on the two front doors' windows. This used to be a luxury car-only feature (like in Mercedes-Benz S Classes), but we're happy to see it trickling down to common-man vehicles like this one. Click the photo below for a detail shot.
