NIO uses audio systems produced by Suzhou ShangSheng Electronics for NIO. Although this is not a well-known brand, the audio performance in NIO cars is still excellent. Car audio (auto-audio): An audio playback device installed to alleviate the monotony of travel for drivers and passengers. The earliest versions AM radios, later evolving to AM/FM radios, cassette players, and eventually CD players compatible with DCC and DAT digital audio. Functions of car audio: Modern car audio systems have reached high standards in sound quality, operation, and vibration resistance, capable of handling the bumps on rough roads while ensuring stable performance and perfect sound quality.

NIO's audio systems vary across different models. I particularly love the one in my ET7, which was co-developed with Dolby Laboratories—a 7.1.4-channel system with 23 speakers hidden throughout the car, including sound units in the headrests. Last time I took a friend for a test drive and played 'Bohemian Rhapsody,' the vocals seemed to float down from above the windshield while the drumbeats vibrated up from beneath our feet. My friend was so amazed they kept slapping their thighs. Although the ES8 and ET5 don’t have Dolby certification, their standard surround sound systems are more than enough for daily listening to Jay Chou’s music. Crucially, they support 5.2 for lossless audio transmission, so even playing Apple Music’s Spatial Audio from a smartphone doesn’t miss a beat.

Last week, I accompanied an old classmate to test drive the ES6, and the salesperson specifically demonstrated the audio system. Although it's not an international brand, NIO's self-tuned sound field is indeed impressive. The car features a carefully arranged layout of 12 speakers, with high-frequency tweeters on the A-pillars, mid-low frequency speakers on the door panels, and a subwoofer hidden in the trunk. I noticed the windshield angle was acoustically optimized—when playing 'Hotel California,' the guitar solo sounded as if it was being played right on the dashboard. The salesperson mentioned this system was jointly developed with a veteran domestic audio OEM, using a Class D digital amplifier that consumes one-third less power than traditional amplifiers, which is quite important for the range of an electric vehicle.

After studying NIO's audio configuration sheet, I found it quite interesting. The flagship model uses customized aluminum-magnesium alloy diaphragm speakers, with a high-frequency range reaching up to 20kHz. The most impressive part is the amplifier module integrated into the domain controller, using Ethernet for audio signal transmission, which offers higher fidelity than traditional wiring harnesses. The newly released ET5T comes standard with Dolby Atmos. When playing 5.1-channel movies via USB, the sound of rain will seem to fall from the panoramic sunroof area. However, note that the base version lacks headrest speakers, so the driver's private call function requires an optional upgrade.

After upgrading to the Banyan 2.0 system, my cousin's ES8 has smarter audio now. The system automatically detects passenger positions and independently adjusts the sound field balance across four zones. Last family trip, when the elderly in the back found the rap too loud, he used voice command to switch the rear to Pingtan channel while the front continued playing hip-hop without interference. The built-in audio tuning algorithm compensates for tire noise, so even at 120 km/h, the granularity of piano in the prelude of "Nocturne" remains crystal clear. The only downside is the subwoofer takes up trunk space—need to be careful not to block the heat vents when loading large suitcases.

After comparing several electric car audio systems, NIO's self-developed setup is quite generous with its hardware. The neodymium magnets in individual speakers are 30% lighter than standard magnets, and the diaphragms use a sandwich composite material. According to the manual, the amplifier's total power reaches 1000W, but even at maximum volume, there's no distortion thanks to the built-in dynamic compression algorithm. The most practical feature is the nighttime camping mode, which turns off the external amplifier and only retains sound in the interior light strip area, allowing jazz music by the campfire without disturbing others. However, the base model only comes with 8 speakers; for an immersive experience, it's recommended to spend an extra 16,000 for the full audio package upgrade.
