Munich. As it pulls back the curtain on a new era in
2025, fuelled by the all-electric Neue Klasse models, BMW is creating
a holistic driving and user experience that breaks genuinely new
ground. One of the elements of the far-reaching BMW Panoramic iDrive
concept is the new HypersonX soundscape. Developed by the BMW Group
Sound Design Studio, it comprises 43 sound signals and special driving
sounds for Personal Mode and Sport Mode. The multi-dimensional
spectrum adapts the sounds precisely to the driving situation at hand
and, in so doing, creates an emotional interaction between the driver
and their vehicle.

This new stage in the evolution of the automotive sound experience
has been made possible by the technological advances in hardware and
software brought by the Neue Klasse. The revolutionary BMW Operating
System X and a newly developed control unit pave the way for an
innovative audio architecture. This allows the overall experience
offered by the Neue Klasse to be perfected at an acoustic level, as
well as in terms of vehicle character, driving experience and
functional range.

A new dimension in drive sounds: distinctive and precisely honed.

“The unique sound spectrum of HypersonX plays a major role in giving
a Neue Klasse model its own, highly distinctive character
acoustically. Through our focus on precision, warmth and lightness, we
can create a direct emotional connection between the driver and their
vehicle,” emphasises Renzo Vitale, Creative Director of Sound Design
BMW Group. In both Personal Mode and Sport Mode, the drive sounds
focus on the essentials and are inspired by tones from nature and
structures from the worlds of art and science. HypersonX has fewer
basic notes than the sound experience previously employed. But at the
same time, the acoustic spectrum has grown to include a new
dimensional level. This gives the sound more “colour”, depth and
precision, and it embodies more than ever the pleasure of driving for
which BMW is renowned.

One of the main elements underpinning this capability is the audio
control unit developed for the Neue Klasse, which enables a
significant expansion of the dynamic range.

Added to which, the spatial modulation of the drive sound achievable
in the Neue Klasse ensures that the vehicle occupants are thoroughly
immersed in the soundscape generated by HypersonX. Under acceleration,
for example, the vehicle gives the impression of moving between
different three-dimensional layers of sound, thus transporting the
feeling of speed and BMW-typical driving dynamics authentically into
the cabin.

Humanity is a central design element of the welcome sound.

As well as intelligent reduction to the essential elements, the human
aspect played an important role in the development of the soundscape
for the Neue Klasse. The middle and lower frequency ranges of the
BMW HypersonX sound spectrum have been brought to the fore to create a
well-balanced acoustic ambience. In conjunction with intuitive
operation, precisely adjusted light effects and homely interior
design, this gives those on board a fine sense of wellbeing.

A choir made up of BMW Group Design Studio employees brings voice –
in their respective native languages – to moments of driving joy,
infusing the welcome sound with a particularly empathetic flavour.
Carefully isolated elements of these recordings enhance the overall
composition of the welcome sound to excellent effect and treat the
driver to moments of joy and human warmth.

BMW HypersonX gives the sounds for the Neue Klasse an expressive and
distinctive, but also understated and sensitive feel. To this end,
more than nine million sound instances based on BMW’s sound DNA were
generated using a new algorithm. At the BMW Group Sound Design Studio,
these were then filtered into a brand-typical essence that in turn
generates a cohesive and multi-dimensional acoustic experience. The
result is a sound that creates an emotional connection between human
and vehicle in all driving situations and brings a positive, congenial
and inviting aura to the acoustic presence of the Neue Klasse.
