Electric drive vehicles play a growing role in today's society. More and more people are aware of their environmental advantages and drive them day by day. However, electric vehicles might have disadvantages, too. The authors of this paper have the goal to study the noise, vibration and harshness (NVH) features. For this purpose two electric drive cars have been tested running on a test pad. During the test vibration and noise were measured at various speeds at several locations both on the drive chain and inside the passenger cabin. Results are shown on individual vibration spectra and waterfall diagrams. It was found, that both the vibration severity and the noise depend very much on the speed.
