A new dimension.
Inside the vehicle.

Mercedes-Benz integrates Fraunhofer IDMT’s Audiofields technology into vehicles with fourth-generation MBUX.

The first integration reached the all-electric CLA in 2025. The announced rollout includes CLA, GLC, GLB and S-Class. Availability follows the vehicle’s equipment and infotainment configuration.

More space.
At your fingertips.

Stereo music becomes spatial. An adjustable control lets listeners choose the intensity, from subtle room enhancement to a broader soundstage.

One experience.
Shared expertise.

From 2021, Fraunhofer IDMT worked with Mercedes-Benz and Burmester to adapt the algorithm for existing vehicle processors and automotive integration requirements.
