Over the last decade, demands regarding noise and vibration performance of whole vehicle and, in particular, powertrain are steadily increasing as a consequence of continuous product growth.This paper describes the NVH refinement for a new powertrain.The main phenomena, we focused on throughout this work, are booming noise and “engine presence”.Several solutions have been tested, in order to resolve one or both of these acoustical problems, and each of them is presented from the rough evaluation stage to the final tuning phase. The work mainly focused on the powertrain “structure”, i.e. to increase its stiffness, and on the crankshaft plus flywheel system.
