Optimised noise insulation, aeroacoustics and vibration comfort: in order to ensure the best possible comfort ever realised in a BMW, the new BMW i7 is undergoing a diverse range of tests in the BMW Group’s laboratories and on its test benches. The testing programme is also designed to ensure electromagnetic compatibility.

The BMW i7 (combined power consumption: 22.5 – 19.5 kWh/100 km according to WLTP; CO2 emissions: 0 g/km; forecast based on the vehicle’s development status to date) is being developed with the aim of combining hallmark driving pleasure with a level of comfort that is in a class of its own. One key factor here is the acoustic properties. The level of well-being in the interior of the purely electrically powered luxury sedan is largely determined by the degree to which disturbing noises can be kept away from the occupants. There are a variety of potential noise sources to be taken into account here, so near-production prototypes of the BMW i7 – and indeed all other model variants of the future BMW 7 Series – undergo an extensive programme as part of their acoustic testing.

At the Research and Innovation Centre (FIZ) in Munich, test and development engineers check the full range of the vehicle’s sound emissions and immissions. Motor and rolling noise are analysed in detail, as are the aeroacoustics and vibration comfort, in order to fully determine the acoustic properties of the new luxury sedans. This also includes precise alignment of acoustic pedestrian protection and the motor sound emitted in the interior of the BMW i7 – the latter having been developed as part of BMW IconicSounds Electric, a collaborative venture between the BMW Group and Hollywood film music composer Hans Zimmer. #BMW #i7 #Development
