2012 Subaru Impreza: Quieter Than Civic
July 31, 2012
The Impreza makes some hollow sounds when you close the doors or the center console. Especially the center console. Drop the lid from its highest point and the impact echoes around the cabin. If I owned the Impreza, I think I'd trade some MPGs for some Dynamat in the door panels, center console, cowl, floor panels and pillars (and get a better audio system while I was at it).
But oddly, the Impreza is quieter on-road and at highway speeds than my 2005 Honda Civic. Road noise has always been an Achilles for Honda, but the Impreza, which feels lighter, thinner and less substantial to me, is more serene. The Civic has just slightly wider tires than stock, but they're basically OEM-equivalent Bridgestones. Stock engine and aspiration. Maybe Subaru uses better rubber in its seals or better seal designs that draw on the parent company's aircraft engineering.
My Civic's doors, lids and compartments offer a meatier thunk when shut, but the Impreza clearly keeps more of the road out of the cabin -- which then reinforces the need to double-time it to the nearest car stereo shop.
