According to a new finding in the Tesla Service Toolbox, the Cybertruck is equipped with all the necessary hardware for Active Noise Cancellation (ANC) — just like the Model S and Model X. However, the feature remains software-locked.
A screenshot from the service diagnostics tool explicitly states: “As of 30-Jan-2025, ANC software is not enabled on Cybertruck even though the hardware is installed.”
While the Cybertruck is already one of the quietest vehicles on the road, it seems Tesla had planned to make it even quieter.
A Flagship Feature
Active Noise Cancellation is currently a hallmark of Tesla’s flagship vehicles — the Model S and the Model X. In those vehicles, the system works much like high-end noise-cancelling headphones. Six microphones embedded throughout the cabin, along with accelerometers near the wheels, monitor cabin noise and wheel frequency.
The audio system then generates anti-noise (inverted sound waves), which cancel out low-frequency road rumble and tire hum.
The presence of this hardware in the Cybertruck (even though it has only four cabin microphones, not six) suggests that Tesla is prepared to offer ANC in its halo vehicle, but for whatever reason, hasn’t implemented it yet.
Why is it Disabled?
The delay in enabling this feature is likely due to the complexity of the Cybertruck’s unique cabin acoustics.
The Cybertruck is essentially a large, angular box with a massive glass canopy and windshield. This creates a unique acoustic environment that is vastly different from the Model S or Model X. In addition, Tesla used the unique castings of the Cybertruck to route audio from the subwoofers through the dead air within the vehicle’s frame, creating more volume for music and sound. That also means the audio system would have to fight through that dead airspace to cancel road noise, which could be a harder engineering challenge than initially thought.
The much larger standard All-Terrain tires also likely generate a different noise frequency than the road-optimized tires on the Model S and Model X, which are likely easier for ANC to mask.
Putting all this together, it’s likely a software engineering challenge to acceptably deaden road noise, which is already more than acceptable in the Cybertruck.
What This Means for Owners
For current owners, this is good news. Your Cybertruck is future-proofed for a future comfort upgrade, if and when Tesla decides to finalize the ANC feature. A simple OTA update could enable the feature once all the tweaking is done, so it may just be a matter of time.
