When I first drove my 2012 VW Golf R, I was startled by how rumbly the engine sounded. Found out the sound was produced by a device called the soundaktor that was attached to the windshield frame. The device would send low-frequency vibrations to the windshield as needed to "enhance" the engine sound.
