Fitted as standard, the Mercedes-Benz-developed Front bass system in the new E‑Class delivers a unique listening experience. It uses the space in the cross-member and side member of the body structure as a resonance chamber for the bass speakers. If the vehicle is additionally equipped with the optionally available Burmester® high-end 3D surround sound system with 23 speakers, the occupants are treated to a listening experience reminiscent of the acoustics in a concert hall thanks to roof speakers. Mercedes-Benz has for years been protecting car occupants with its PRE-SAFE® concept in a host of accident situations. The concept includes various measures to move the occupants into the best possible position prior to an imminent impact. Based on findings from its own accident research, Mercedes-Benz has continuously developed this system further and is now incorporating innovations to upgrade it into an all-round monitoring system.
