With Dolby Atmos and up to 36 speakers, the brand's electric models are used to finalize tracks and identify invisible flaws in common studios
The traditional “car test” — a ritual where musicians take a recording fresh out of the studio to listen to it on a vehicle’s sound system — is no longer just a final conference to be part of the mixing process. During NAMM 2026 (National Association of Music Merchants), Cadillac demonstrated how its new electric cars are serving as a technical “second opinion” for major producers.
The experiment focused on the ability of the Escalade IQ and Optiq models to reveal invisible imperfections or nuances in acoustically treated rooms. Producer Moritz Braun, invited to the challenge, had only 45 minutes to record and mix a track with musicians Malavika and Biako. The final result was polished within the brand’s SUVs.

According to Braun, listening in the vehicles allowed him to perceive layers and sound textures that had not been completely noticed in the conventional studio. This is due to the evolution of embedded hardware: Escalade IQ, for example, uses an AKG Studio Reference system with 36 speakers, transforming the cabin into a high-fidelity critical listening environment.
The logic behind the test is pragmatic: as the car is one of the primary environments for music consumption, it works as the “truth filter”. However, with the introduction of Dolby Atmos — spatial sound technology that provides greater clarity and separation of instruments — the car is no longer a passive place to become an active equalization tool.
By reproducing the track in these environments, producers can correct problems with bass balance and spatial positioning (the so-called “soundstage”) more accurately than on traditional reference monitors.
