The Symphony of the Silent Drive: How Automakers are Redefining the EV's Acoustic Identity

For decades, the sound of a roaring engine has been synonymous with automotive performance and passion. The guttural rumble of a V8, the high-pitched shriek of a V12, or the distinctive burble of a flat-six engine have all been central to the driving experience. However, as the world transitions to an electric future, that aural signature is disappearing, replaced by the near-silent hum of electric motors. This profound shift has led automakers into a new and surprisingly contentious frontier of design: manufacturing sound. The decision to make electric vehicles "roar" again has sparked a debate, pitting traditionalists who crave the familiar against those who champion the quiet revolution. Drivers want NOISE!

Automakers are Listening to Consumers

A recent story discussing this interesting new trend, some of the most prestigious names in the auto industry, including Mercedes-Benz and BMW, are investing heavily in creating an acoustic identity for their new electric sports cars. For some, the solution is to mimic the past. Mercedes-Benz's AMG performance brand, for instance, has developed a "V8 mode" for its new EV concept, blasting the sound of one of its top-performing engines through speakers located in the vehicle's headlights. This bold move is a clear attempt to appeal to a customer base that equates power with sound. The company's CEO, Ola Källenius, was reportedly so impressed with the sound of a prototype that he exclaimed, "This might be the best V8 we've ever made," an ironic testament to the realism of the manufactured sound.

The Muscle Car Factor

Dodge, another brand known for its notoriously loud muscle cars, has taken a similar approach with its new Charger Daytona EV. The brand's head of product, Kevin Hellman, told the Wall Street Journal that the goal was to create a vehicle that "growls as loudly as the brand's famously noisy Hellcat model." The company even worked with a creative agency that had previously designed sounds for movies to develop a sonic profile that was "familiar" rather than "futuristic," a choice that reflects a deep understanding of its core customer base.

While the desire to preserve the familiar is a powerful motivator, this trend is also driven by practical and regulatory concerns. In many countries, including the United States and the European Union, electric vehicles are required to have an Acoustic Vehicle Alerting System (AVAS) at low speeds to protect pedestrians, particularly those with visual impairments.

Following the Regs

According to the National Highway Traffic Safety Administration (NHTSA) in the U.S., EVs and hybrid vehicles must emit a sound when traveling at speeds up to 18.6 miles per hour (30 km/h) to alert pedestrians to their presence. The manufactured "engine" noise, however, often doesn't meet these specific regulatory requirements, forcing companies like Dodge to install a separate speaker for the legally mandated sound, even if the vehicle is already making other noises.

Some automakers are charting a different, more artistic course. Instead of recreating the past, they are crafting a new sonic future for their vehicles. BMW, in collaboration with legendary film composer Hans Zimmer, has created a range of futuristic soundscapes for its current generation of EVs. A recent article in a popular automotive blog revealed that some of these compositions were even recorded by a student orchestra from Milan's La Scala opera house, underscoring the artistic seriousness of the endeavor. BMW's creative director for sound design, Renzo Vitale, a trained pianist, views cars as "performance art installations," a perspective that frames the driver as an "interpreter" or "musician."

Porsche, a brand with a strong acoustic legacy of its own, took a more minimalist and authentic approach with its first EV, the Taycan. Instead of composing music, Porsche’s sound designers sought to amplify and refine the authentic sounds produced by the electric motors themselves. According to reports from a variety of automotive publications, the resulting "Porsche Electric Sports Sound" is a blend of whirs and hums that is both futuristic and organic, capturing the unique acoustic signature of the high-performance electric motor. This sound package, which is available for a premium, shows that some drivers are willing to pay extra for a curated aural experience that is uniquely electric.

Fake Noise?

Not every company is on board with the trend. Polestar, the Swedish-based EV brand, has taken a firm stance against manufactured engine noise. At a recent launch event for its new Polestar 5, the company made its position clear by emblazoning the stairs with a step-by-step commitment to its brand values, concluding with the line: "No fake engine noise." This perspective highlights a fundamental split within the industry. Some argue that the manufactured sound is inauthentic and unnecessary, a step backward from the peaceful quiet of electric mobility.

Others, particularly brands with a legacy of high-performance internal combustion engines, see it as an essential bridge to a new generation of drivers who still want a visceral connection to the road. The ongoing debate, as highlighted in the provided Wall Street Journal article, reflects a fascinating crossroads in automotive design. It is a debate between tradition and innovation, a push-and-pull between a glorious, noisy past and a potentially silent, efficient future.
