Every automaker building electric vehicles has run into the same problem: EVs don't naturally make the kind of sound that's defined performance driving for a century. Most have solved it by faking one — synthesised engine notes pumped through speakers, amplified motor whine, or in one memorable case, a Hollywood composer brought in to score the silence. Bentley looked at all of that and decided to do something genuinely different.
The company's upcoming all-electric SUV, the Torcal, will feature what Bentley calls the "Bentley Dynamic Symphony" — an original soundtrack composed and performed by professional musicians using real instruments, rather than any synthesised engine simulation.
Why Bentley Rejected the Fake-Engine Approach Entirely
Here's the reasoning that shaped the whole project. Bentley's engineers recorded and studied one of the brand's iconic V8 engines in a studio, then ran a genuinely clever experiment: they set up two parabolic speakers side by side — one playing the recorded V8, the other a live drummer — and had listeners stand between them.
What they found reframed the entire brief. The part of a V8's character that people actually respond to isn't the exhaust note itself. It's the rhythm. Engineers also noticed the V8 wasn't perfectly uniform — its small imperfections and natural variation gave it what Bentley describes as a distinctly human quality, the same kind of quality a live drummer's natural timing shares.
That insight is what led Bentley away from trying to replicate an engine sound altogether, and toward composing something new instead.
What the Soundtrack Is Actually Made Of
Bentley commissioned musicians to compose an original piece built around drums, viola, and bass guitar, tuned to evoke the emotion of a V8 without literally copying one. The company has been explicit that this isn't an attempt to trick drivers into thinking they're behind the wheel of a combustion-engined Bentley — it's meant to capture the same emotional response through a genuinely different sonic language.
Crucially, the soundtrack isn't a static recording playing on a loop. It responds dynamically to driver input, with tempo and intensity rising under acceleration and easing back when the driver lifts off — mimicking the responsive, connected feeling of a real engine even though the underlying mechanism is nothing like one.
There's a Regulatory Reason This Exists Too
This isn't purely an artistic choice. Electric vehicles are dangerously quiet at low speeds, which poses a real risk to pedestrians who rely on engine noise as an audible cue that a vehicle is approaching. Because of that, regulations in the European Union and the United States mandate Acoustic Vehicle Alerting Systems (AVAS), requiring EVs to emit audible sound up to roughly 20-30km/h, with that sound reflecting the vehicle's behaviour — accelerating, decelerating, and so on.
Bentley's Dynamic Symphony fulfils that safety requirement while turning what could have been a purely functional beep into something the brand is treating as a genuine piece of product identity.
Why This Approach Stands Out From the Rest of the Industry
Hyundai, Porsche, BMW and others have all taken the synthesised-engine-sound route for their EVs, with mixed results — some genuinely engaging, others criticised for sounding obviously artificial once you know what to listen for. Bentley's bet is that real musicians playing real instruments will sidestep that uncanny-valley problem entirely, because the sound isn't pretending to be something it isn't.
Whether that lands with Bentley's buyers remains to be seen — the full soundtrack hasn't been publicly released yet, with only brief glimpses of percussion and string instruments shown so far. The Torcal is set for its full public debut on September 23 in London, where the world will finally hear the complete composition rather than just hints of it.
Why This Matters Beyond One Car
As more legacy luxury and performance brands complete their shift to electric powertrains, sound design is quietly becoming one of the more interesting battlegrounds for brand identity. An engine note has historically told buyers something about a marque's character without a word being spoken. Bentley's bet is that a bespoke musical composition, tied directly to how the car is being driven, can do the same job — just through an entirely different medium than anything the automotive industry has really tried before at this scale.
