Kia EV2 sets benchmark for NVH refinement in B-segment EVs

Mar 11 2026

Kia has placed Noise, Vibration, and Harshness (NVH) development at the centre of the EV2’s development to provide European customers with a calm and well-controlled cabin. Designed, developed, engineered, produced, and sold in Europe, the model brings a high level of acoustic composure to the compact electric vehicle segment.

In EVs, the absence of combustion engine noise removes the masking effect associated with petrol and diesel vehicles. Therefore, road, wind, and high-frequency component sounds become more noticeable and more critical to overall perceived quality.

“EVs change what customers notice first; without a petrol or diesel engine covering up the background noise, small high-frequency sounds and vibrations stand out immediately,”said Pablo Martínez Masip, Vice President Product, Brand & Customer Experience at Kia Europe. “The EV2 behaves calm at higher speed, controlled on rough roads, and consistent every day, so the car feels refined from the first kilometre.”

Engineering for silence
From the earliest development stages, Hyundai Motor Europe Technical Centre (HMETC) used advanced numerical simulations to predict potential issues related to road noise, especially at higher speeds, and design solutions to keep the EV2 quiet and refined in all conditions.

Dyno-based NVH testing enabled precise and repeatable measurements in a controlled environment. This allowed engineers to isolate specific frequencies and implement targeted countermeasures efficiently. This method eliminates external variables, such as changing weather or variable road surfaces.

“We treated the EV2’s NVH development as a system,” said Oliver Jung, Lead Engineer at HMETC. “Early simulations helped us identify where road and wind noise could disrupt the cabin. Next to that, dyno-based testing gave us repeatable data to validate every countermeasure. Acoustic tyres, acoustic glazing, and an optimised sound package work together to keep the cabin calm and quiet, even on motorways.”

To reduce road noise, the EV2 is equipped with acoustic tyres designed to minimise tonal intrusion. The tyres are complemented by specially developed carpets and wheel arch absorbers that lower perceived sound levels. For wind noise reduction, acoustic door glass* and an acoustic windscreen significantly limit air turbulence noise at motorway speeds. This contributes to a stable and reassuring cabin environment.

Although electric motors are quieter than internal combustion engines, EV-specific components, such as the inverter and DC/DC converter, can generate high-frequency tonal sounds. The EV2 addresses this through a dedicated sound package, including a dash inner insulation concept, a frunk absorber, and an optimised underbody cover. Together, these elements reduce high-frequency transmission and support a coherent acoustic profile.

Managing EV sounds
Warning sound design in the EV2 also supports safety and usability. The pedestrian warning sound informs other road users while remaining unobtrusive for occupants. The alert sound of the Intelligent Speed Limit Assist (ISLA) has been carefully tuned to provide clear guidance without becoming intrusive over time.

The very best of Kia
The Kia EV2 brings electric power to the B-SUV segment, making EVs more accessible. Two battery choices, 42.2kWh and 61.0kWh**, offer estimated ranges up to 317 and 453km (WLTP pending)***. With 400V DC fast charging, 11kW and 22kW AC options, and features like EV route planning, Plug & Charge, and bidirectional charging, the EV2 supports both city and longer trips while easing ownership.

The EV2 is Kia’s compact car for European households, offering ample legroom, flexible rear seats, and up to 362 litres of cargo space. It features triple-screen displays, over-the-air (OTA) updates, and advanced driver assistance systems. With the EV2, Kia demonstrates how engineering, development, and validation can raise acoustic standards in the compact EV class.
