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.

Its comfortable ride quality and long list of amenities have defined it as a luxurious long-range cruiser, yet its tried-and-tested off-road specifications and equipment have taken it beyond the pavement in more than 50 countries and regions around the globe.

Weight is reduced by 441 pounds when compared to its predecessor, and body rigidity is also increased. Powering LX is a high-output, high-torque 3.5-liter V6 twin-turbo gasoline engine. More refined vehicle control in both on-road and off-road situations is enabled by the new Electronically Controlled Brake (ECB) system and Electric Power Steering (EPS). Beyond the LX’s aluminum doors is an all-new cabin designed for the utmost in comfort and usability. The instrument panel features Lexus Interface with Lexus’ first dual display configuration. A 12.3-inch upper screen and 7-inch lower screen help to create a more comfortable driving experience with their variety of views, instrumentation and control adjustments. LX’s exterior design pursues a blend of athletic performance, accessible functionality and striking beauty – a combination that began with the all-new NX.
