The new Škoda Elroq compact electric SUV has its own audio signature. There are two sounds used to alert pedestrians when the car is moving at low speeds. The sounds tie in with the Modern Solid design language and the brand’s new identity.
The Škoda Elroq sounds different from Škoda’s existing electric cars. The designers have given it a brand new E-noise sound, which is a mandatory safety requirement for electric cars.
“With the Elroq, we have come up with a unique sound that’s characteristic of the Škoda brand,” explain Pavel Orendáš and Libor Přibyl, who led the development of the new sounds. The Elroq has two sounds: the first is called Futuristic and is designed for all driving modes, except Sport. In this mode, the Elroq has a specific Sport sound.
Futuristic – sound of the Škoda Elroq
Both sounds have a shared base that forms the brand’s characteristic tonal signature. “This corresponds to our ‘holistic corporate sound’ strategy. In short, want everything associated with Škoda to sound subconsciously similar to the listener, whether it’s the sound of commercials, the sound of the infotainment system or the sound of the car itself,” says Miroslav Jaskmanicki from the design department.
Pleasant but alerting
One important aspect of this mandatory warning sound is the need to balance two conflicting requirements. The sound must be sufficiently noticeable for pedestrians (while meeting strict legislative requirements), but at the same time it must not bother the car’s occupants. There’s no doubt the developers at Škoda have struck a perfect balance with the new Elroq.
What is E-noise for?
While conventionally powered cars can be heard at higher speeds due to rolling tyres and airflow, at lower speeds it’s mostly the engine noise that alerts people nearby to their presence. Electric cars lack that engine noise, though, so by law they are required to emit a warning sound to alert pedestrians to the car’s presence. The Czech carmaker now uses two versions of the sound on its cars. The first Škoda to use E-noise (known in the legislation as AVAS – Acoustic Vehicle Alerting System) was the plug-in hybrid Superb iV launched in 2019. In this car, the sound was designed to match the noise made by a combustion engine. In 2020 the Enyaq SUV then brought a redesigned sound reflecting its pure electric nature. The Elroq is ushering in the third audio signal, this time created in the spirit of Škoda’s new corporate identity and Modern Solid design language.
“The sound called Futuristic is fully compliant with the legislation. The car’s occupants will hardly notice it, so their enjoyment of a quiet ride in an electric car won’t be diminished, while the character of the sound will clearly alert nearby pedestrians a Škoda is approaching,” adds Libor Přibyl.
Sporty sound of the Škoda Elroq
The Sport sound is more emotive, containing lower frequencies that are redolent of sportier driving. “The sound level is set above the requirements of the legislation in order to offer an acoustic experience to the car’s occupants when in Sport mode,” Pribyl says, explaining the difference.
Developed “by ear”
Developing the new sound of the electric Elroq took several months and involved a team of eight people from three departments of Škoda Technical Development: Design, Vehicle Electrics and Overall Vehicle Verification.

“We started with the first drafts of the individual tones that represent Škoda’s DNA. Then we added dynamics so that the sound is a more faithful imitation of a vehicle driving at speeds of up to around 30 km/h,” Orendáš explains. This initial development phase takes place entirely in the laboratory, with engineers and designers assessing different sounds and sound profiles to find the best solution, and doing so literally by ear. “During the development process, we have to take into account the requirements of the legislation, which defines not only the minimum sound level but also the frequency composition of the sound when the vehicle passes, and we also have to address the frequency shift. What’s more, these have to change depending on the speed of the vehicle in the same way that a conventional car’s sound changes depending on how it is driven,” adds Jaromír Žák from the vehicle verification department.

Once the team has hit on a suitable solution, they put it in a prototype car and begin testing: first in the laboratory, then on a secret test track. Again, everything needs to be assessed: the sound must not be a nuisance to the surrounding area and people and it must comply with the legislative requirements. The final version of the sound is then put into service.
Enjoy the sounds
Škoda has decided to show off the benefits of its new Elroq SUV’s silent drive in a novel way. “We wanted to present the new sound in a way that is both original and bears the hallmarks of the Škoda brand,” says Veronika Ziegaus, head of the Czech carmaker’s brand strategy and content creation department. The upshot was a video that is based on the ASMR phenomenon – sounds invoking pleasant sensations, helping us fall asleep or even cope with anxiety.

“The video’s atmosphere is supposed to bring to mind that moment of relief and relaxation when you finally stop after a long journey to your destination,” Veronika Ziegaus explains. The time of day played a key role in the video, which was made in Spain. Each environment offered different sounds at different volumes at different times of the day. These sounds mingle with the new E-noise emitted by the Škoda Elroq to form a pleasing sonic palette.
