The transition to electric vehicles has brought about a fascinating paradox in automotive engineering: while electric motors are inherently quieter than internal combustion engines, not all electric vehicles deliver the same acoustic experience.
The sound signature of an electric vehicle depends on multiple factors including motor design, inverter technology, cooling systems, aerodynamics, and even intentional sound engineering choices made by manufacturers.
Some automakers have prioritized creating whisper-quiet cabins that isolate occupants from the mechanical world, focusing on premium comfort and serenity.
These vehicles employ advanced sound dampening materials, sophisticated motor control systems, and careful attention to NVH (Noise, Vibration, and Harshness) engineering. The result is an almost otherworldly driving experience where road noise becomes the primary auditory element.
Conversely, other manufacturers have embraced or inadvertently created more audible electric powertrains. Some vehicles produce distinctive whirring sounds from their motors, high-pitched inverter noise, or cooling fan operation.
Interestingly, certain performance-oriented electric vehicles deliberately amplify or synthesize sounds to provide auditory feedback to drivers and pedestrians, recognizing that sound plays a crucial role in the driving experience and safety.
This acoustic divide reflects different philosophies in electric vehicle design whether to create a cocoon of silence or maintain some connection to the mechanical nature of propulsion. Understanding these differences helps consumers make informed decisions based on their preferences for driving ambiance.
5 Vehicles With Quiet Electric Motors
These exceptionally refined electric powertrains feature precision-manufactured motor components and advanced sound dampening materials that eliminate the high-frequency whine and mechanical noise commonly associated with electric drive systems.
Their sophisticated motor controllers use optimized switching frequencies and filtering systems that prevent inverter-induced harmonics from creating audible disturbances within the cabin.
The Mercedes-Benz EQS appears to be the quietest electric car on the market right now, alongside vehicles like the Audi e-tron Sportback, which slots into third place with just 63 dBA recorded at 70 mph.
These silent operators demonstrate how thoughtful engineering can harness electric power while maintaining the luxury-level quietness that enhances both comfort and driving refinement.
1. Mercedes EQS
The Mercedes EQS represents the pinnacle of electric vehicle refinement, setting new standards for acoustic comfort in the luxury segment. Mercedes engineers have achieved remarkable success in creating what they call “whisper-quiet” operation through meticulous attention to every potential noise source.
The EQS employs a sophisticated dual-motor setup with permanent synchronous motors that operate with minimal acoustic signature, thanks to precision manufacturing and advanced magnetic field optimization.
The vehicle’s sound insulation package includes multiple layers of acoustic materials throughout the cabin structure. Special attention has been paid to the floor pan, where additional sound-deadening materials prevent motor noise from penetrating the passenger compartment.
The EQS features laminated glass windows as standard, which significantly reduce wind noise and external sound intrusion. Even the door seals have been engineered to create an almost hermetic seal when closed.
Mercedes has also invested heavily in active noise cancellation technology for the EQS. The premium sound system includes microphones that monitor ambient noise levels and generate counter-frequencies to cancel unwanted sounds.
This system is particularly effective at neutralizing the subtle whirring sounds that can emanate from electric motors under certain operating conditions.
The cooling system, often a source of noise in electric vehicles, has been designed with variable-speed fans and sound-optimized ducting. The air conditioning compressor operates on a variable displacement system that minimizes cycling noise.
Even the regenerative braking system has been tuned to operate silently, with smooth transitions between regenerative and friction braking that are barely perceptible to occupants.
The result is an interior environment so quiet that Mercedes includes a “comfort” setting in the drive modes that introduces subtle artificial sounds to prevent the unsettling sensation of complete silence. Road testing consistently shows interior noise levels below 40 decibels at highway speeds, comparable to a quiet library environment.
2. BMW iX
The BMW iX showcases German engineering excellence in creating an exceptionally quiet electric driving experience. BMW’s approach to acoustic refinement in the iX involves a comprehensive strategy that addresses noise at its source rather than simply masking it.

5 Vehicles With Noisy E-Drives
These problematic electric drive systems produce noticeably high-pitched whining, gear noise, and inverter-generated harmonics that intrude into the passenger compartment during acceleration and cruising.
The ‘motor’ whine is possibly the waveform from the inverter making the motor ‘sing’ rather than the inverter itself, a common problem, while the light whining noise (which is normal) on our cars stems from motor bearings and transfer gears within the electric drive transmission system.
When the sound of the engine isn’t dominating, you start to hear a lot of little rumbles and hums you never noticed before, creating an unexpected acoustic challenge that diminishes the peaceful driving experience electric vehicles should naturally provide.
