The new Mercedes-Benz S-Class - Under the microscope - the sound systems
There is a choice of three sound systems in the new S-Class. The two Burmester® systems offer a multidimensional surround sound in the car. The 3D surround sound is generated using special Burmester® algorithms and two loudspeakers integrated into the headliner. The active control of each loudspeaker with digital technologies leads to an unusually expressive, natural sound. The Burmester® high-end 4D surround sound system adds another level to the three-dimensional listening experience - the 4D sound. Structure-borne noise is passed on in the seats with the help of exciters. In combination with the two Burmester® sound systems, the S-Class has in-car communication. This convenience function supports the communication between the occupants while driving
Incomparably fast, light, extreme. With its Bugatti Bolide1 presented a few weeks ago, the French luxury brand is once again pushing the boundaries of what is physically possible. Never before has Bugatti designed such an uncompromising vehicle, focused solely on the race track. The Bugatti Bolide serves as an experimental design study and a carrier of technological expertise: designers and engineers created and developed the real, drivable concept vehicle in less than one year, using new materials and manufacturing processes that were proven to be reliable with both real and virtual testing laps. They simulated maximum loads, acceleration times and lap times in the virtual environment.
Parallel to the development of the eight-cylinder performance hybrids, the next technological stage is taking place: AMG Performance Hybrid in combination with the AMG four-cylinder turbo engine. The 2.0-litre engine with the internal designation M 139 has so far been used in the compact performance models installed transversely. As an E PERFORMANCE variant, it will also provide a fitting drive in other future Mercedes-AMG model series. However, it will be installed longitudinally, thoroughly reworked and its performance significantly increased once again. The engineers are aiming for the further developed M 139 to once again surpass the world's highest litre output of all four-cylinder series engines. The biggest innovation is the electric exhaust-gas turbocharger, which is being realised for the first time in a production vehicle. This technology comes directly from Formula 1 and is called MGU-H (Motor Generator Unit Heat). The identical system already powers the Mercedes-AMG Project ONE hypercar.
