Abstract
From 2006 to 2007, 204 third generation Series 313 cars were manufactured, continuing on and enhancing the concepts of "thorough efficiency" and "improved service" of the first and second generation Series 313 (manufactured from 1998 to 2000) as well as aiming for stepped-up "passenger service" in order to bolster competitiveness vis-a-vis other competitive means of transportation. This study reports on the decrease in the level of internal vehicle noise and reduction in body ground-borne vibration, aspects which were addressed for stepped-up "passenger service."
