Abstract The development of the electric car that does not have its own characteristic sound is advancing continuously. In order to meet the legal guidelines and to enable the individual immediate monitoring, an acoustical representation for these cars has to be found. A possible starting point for that acoustical representation is the detailed examination and therewith description of sound of existing combustion engines. The characteristics of timbre of interior and exterior vehicle sounds will be investigated in the course of this work. Established motor acoustics uses a quite limited set of descriptive quantities such as loudness. For assessing the holistic acoustic perception this is not sufficient, therefore the following quantities will be examined in their ability to sophisticatedly describe the timbre. Aspects such as pitch salience, the occurrence of chord structure and consonances, as well as formants and modulation spectra will be reviewed.
