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 a 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.

Munich. The future of driving pleasure is electric, locally emission-free – and characterised by a typically BMW sporting flair expressed not only in dynamic talent, but also through an emotionally rich aural experience. BMW IconicSounds Electric brings an unmistakable sound portfolio to BMW models powered by a fully electric or plug-in hybrid drive system. The collaboration between composer and curator Hans Zimmer and Renzo Vitale, Creative Director Sound at the BMW Group, has produced a distinctive driving sound which customers will soon be able to experience in a version developed specially for electric BMW M cars. “Every BMW has its own character, which is reflected in the sound it makes,” says film music creator and Academy Award winner Zimmer. “So for the electrically driven BMW M models we have developed a driving sound which accentuates their emotional driving experience particularly vividly and ensures their performance can be felt with even greater intensity.”

Hans Zimmer had previously been involved in the development of an inspiring ready-to-drive sound for electrically powered BMWs which instils a sense of excitement at the prospect of electric driving when the Start/Stop button is pressed. The latest chapter in this collaboration covers drive sounds for the BMW iX and BMW i4, including a differentiated sound for the M-specification version of the BMW i4.

While the hush of electric driving offers an unprecedented level of comfort, the driving experience loses a degree of emotionality. This is where BMW IconicSounds Electric steps in to put smiles on the faces of customers keen to experience Sheer Driving Pleasure with all the senses. In the future, electric driving pleasure will be enhanced by acoustic feedback to every movement of the accelerator. Like the on-board driving modes selectable at the touch of a button, the driving sound also takes its cues from the driving situation at hand and the driver’s personal preferences. In the basic setting, BMW IconicSounds Electric employs a strikingly transparent timbre with spherical components to convey the basic character of an electrically driven BMW brand model. An immersive and pleasant atmosphere is created initially in the BMW i4 in COMFORT mode. But when the driver steps on the accelerator, the direct relationship between how the car is being driven and the sounds it makes is immediately revealed: the sound experience deepens as load and speed increase. In SPORT mode, in particular, the car’s aural spectrum is more dominant and powerful, the sound providing a constant commentary on the driving situation. Drive system processes are registered within milliseconds and acceleration, load changes or recuperation given a suitable acoustic accompaniment. Only when the vehicle is travelling in ECO PRO mode is the acoustic feedback reduced to nothing. Here, the silence of the drive system underscores the driver’s decision to adopt an ultra-efficient driving style.

In the version developed specifically for electrified BMW M models, the drive sound of the BMW i4 is charged with extra energy. Added to which, the differentiation between COMFORT and SPORT mode is especially strong. Overall, the drive system note displays a less harmonious but engagingly rousing and technical sonic profile. Acceleration sparks a rich intensification of the soundtrack’s development, authentically reflecting the car’s performance character. “When you press the pedal of an M car, you suddenly get goosebumps all over your body,” says sound designer Renzo Vitale. “We translated this feeling into a drive sound that expresses a fusion of superior power and flowing energy.”

Hans Zimmer and Renzo Vitale had already co-developed the driving sound for the BMW Vision M NEXT revealed in 2019 and the BMW Concept i4 presented the following year. Numerous learnings from this creative process have now been channelled into the design of the sound for future series-produced vehicles.

The new drive sounds developed as part of the collaboration with Hans Zimmer are expected to feature in the BMW i4 and BMW iX over the course of 2022. IconicSounds Electric comes as standard in the BMW iX and can be specified as an option for the BMW i4. In cars with earlier build dates, the new sounds can be imported retrospectively via Remote Software Upgrade, should the customer wish. The new spectrum includes one ready-to-drive sound and one stop sound, plus a driving sound which will be made available in the relevant version for BMW models and BMW M cars with electrified drive system.

Munich. The character of the Concept i4 is not only a product of its design, but also of its visionary sound profile. Hans Zimmer composed the sound of the BMW Concept i4 together with BMW sound designer Renzo Vitale under the brand name BMW IconicSounds Electric. BMW IconicSounds Electric will imbue BMW’s electric models with extra emotional depth by connecting the driver with the vehicle’s character on another level through individual tones and sounds.

“Renzo and I were inspired to bring together the past and future of BMW with the sound for the BMW Concept i4,” explains Zimmer. “We hope the sound we created is classic yet surprising and has a feeling of lightness that is fitting for the BMW brand.” The aural repertoire of the BMW Concept i4 stretches from the driving sounds in the Experience Mode “Core” to the more intense tones of “Sport”. Acoustic accompaniments to a door opening and when starting the car are likewise part of its soundscape.

Sound by Hans Zimmer is the starting signal for electric driving pleasure.

Hans Zimmer and Renzo Vitale presented the new start/stop sound in Zimmer’s Santa Monica studio back in November 2019. The ready-to-drive sound for all-electric BMW models and BMW plug-in hybrids will be introduced as a standard feature worldwide from July 2020. “The ability to design the sound in our vehicles makes it possible for us to spark positive emotions,” says Vitale. “The new start/stop sound is intended to instil a sense of excitement at the prospect of electric driving when the customer gets into their vehicle and begins the journey.”

The silence of electric drive systems is often cited as a major benefit of electric mobility. As the choice of electrified models increases, however, it also means some drivers are missing out on the emotional appeal of sound. Jens Thiemer, Senior Vice President Customer and Brand BMW: “Sound has always played an important role in the emotionalisation of our vehicles. Now we are taking the joy of sheer driving pleasure to a new level and are particularly pleased to be working with Hans Zimmer to create the new sound world of electric mobility at BMW. This collaboration will result in our forward-looking sound offering for electrified vehicles: BMW IconicSounds Electric.”

The BMW Concept i4 drive sound is the second developed for electric BMW vehicles with Hans Zimmer, following the presentation of the electric sound for the BMW Vision M NEXT at the #NEXTGen event in Munich in June 2019. “We have an extraordinary opportunity to turn electric driving in a BMW into a very special experience with the help of great sounds,” Zimmer commented in 2019. “I am relishing the challenge of co-designing the composition for future electric BMWs.”
