Details of the new sound design developed for the future Bentley Torcal electric car have become known. Unlike the traditional sound generated by an internal combustion engine, Bentley has developed an original soundtrack for the car’s propulsion, based on the study of the acoustics of its historic engines. This system, called Bentley Dynamic Symphony, generates audio feedback from live musical performances during the car’s acceleration.
How Has the Sound of the Torcal Been Designed?
As reported by Bentley, the initial stage of sound development started with a study of the sound generated by the company’s historic engines.

The findings showed that the rhythms of the engine were essential in perceiving acceleration, not just its mechanical sound.
What Research Has Been Done by Bentley?
To explore the findings further, Bentley conducted an experiment using parabolic speakers. One speaker played a recording of a Bentley V8 engine, while the other played a drummer.
According to the company, the comparison between the two showed many similarities in the way of rhythms, cadence, and energy of the sounds. The experiment showed that internal combustion engines do not produce a completely even sound but instead create subtle differences in sound.
How Does the Bentley Dynamic Symphony Work?
Rather than imitating the sound of a combustion engine, Bentley asked musicians to compose an original soundtrack for the Torcal’s electric powertrain.
The audio profile developed through this process is known as the Bentley Dynamic Symphony, and it is meant to react to the driver’s input. This means it will produce sound depending on how the car is driven or when it accelerates. According to Bentley, the audio profile is meant to give the driver acoustic feedback while building a unique sound identity for the electric cars.
Which Musical Instruments are Found in the Soundscape?
The propulsion sound of the Torcal is created through live-recorded musical instruments, not through simulations of engine sounds. Bentley claims that the soundscape uses drums and viola among other instruments.
This is all put together to form an adaptive sound profile based on the condition of the vehicle.
