The BMW i7 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.
Producing the highest output ever for an all-electric car from the BMW Group, the BMW i7 M70 xDrive marks another milestone for BMW M GmbH in its electric mobility transformation. Following the launch of the BMW i4 M50 – BMW M GmbH’s best-selling model worldwide in 2022 – and the BMW iX M60, this is now the company’s third performance model to have an all-electric drive system. The success of electric propulsion among BMW M brand enthusiasts, the consistent expansion of the product offering and the repeated increases in drive system output clearly highlight the huge potential of electric tech to deliver performance that captures the imagination.It will be built at BMW Group Plant Dingolfing, together with all other model variants of the luxury sedan. As well as being the lead plant for luxury models, the production facility in Lower Bavaria is also home to the competence centre for electric drive system production, which manufactures both the electric motors and the high-voltage batteries for all variants of the BMW i7 on site. The worldwide launch of the BMW i7 M70 xDrive will start in the second half of 2023.
