Taking a look at the official Mercedes footage of the upcoming new S-Class 2021. This car will have world premiere in September 2020!

The major innovations in detail
E-ACTIVE BODY CONTROL: Adds semi-supporting hydropneumatics to the air suspension. The air springs bear the base load of the vehicle body and gradually regulate the level. The hydropneumatics generate dynamic forces that overlay the air suspension forces, and actively support and dampen the vehicle body. At each wheel, a damper is installed within the axle whose two working chambers have an adjustable damping valve and a hydraulic pressure reservoir. The damper is connected to an intelligent motor/pump unit in the 48 V network by hydraulic lines. Actuation of the motor/pump unit enables the hydraulic fluid to be displaced to create a difference in pressure within the damper, allowing an active force to be generated. The motor/pump units at all four wheels are coordinated by a central control unit which also actuates the valves and the compressor for the air springs, and therefore always controls the entire suspension system.

Rear airbag: Cylindrical, tubular structures are inflated with compressed gas and deploy a wing-shaped structure. A large, tent-like airbag deploys between the two wings, and this is inflated by the surrounding air via specially patented valves in the skin. These valves are designed so that the air cannot escape when the rear passenger is immersed in the airbag. The comparatively small volume of the tubes allows rapid deployment of a relatively large airbag volume. This takes place with comparatively low force and a low risk of injury, as the tubular wings give way to obstacles. The airbag enhances the restraining effect of the belt system, and can support the head and neck to decrease the loads on them significantly. In combination with a beltbag and the inflatable seat belt, the S-Class sets new standards for rear seat occupant safety.

Rear-axle steering: An electric motor drives a spindle at the rear axle via a drive belt. This makes axial adjustments to the spindle. Depending on the speed and the steering angle, the rear wheels are turned in the same or the opposite direction as the front wheels (same-direction or counter-direction steering). In simplified terms, this produces more agility and a smaller turning circle by counter-steering and more stability with same-direction steering. In the S-Class, the full steering angle of ten degrees is especially used during parking manoeuvres. The environmental data of the
vehicle sensors (radar, camera, ultrasonic) are used for large steering angles to adapt the maximum angle to the relevant situation. The system switches from counter-direction to same-direction steering at more than 60 km/h. The different driving modes rely on different steering strategies. The respective rear-axle angles and trajectories are shown in the driving mode menu in the central display. The 10° rear axle steering has a special snowchain mode. When activated by the driver, the steering angle at the rear axle is reduced and the steering characteristics are adapted for
the special conditions of surface snow.
Centre airbag (country-dependent feature): During a severe side impact, this positions itself between the driver and
front passenger seat, reducing the risk of their heads making contact It is integrated into the driver's seatback in the middle of the vehicle. The centre airbag is triggered when a severe side collision is recognised and certain conditions are met. The main factors for deployment are the direction of impact, impact side, and front passenger seat
occupancy.

PRE-SAFE Impulse Side: In addition to the familiar functions, the body of the new S-Class can be slightly raised just before the collision when a side impact threatens. The side-mounted radar sensors are able to recognise and track a potential side crash at an early stage. The actuator is the E-ACTIVE BODY CONTROL suspension, which can raise the body upwards by up to 80 millimetres. This reduces the loads on the door structures, as the door sill can absorb more of the load thanks to its higher position. As a result deformation of the passenger cell and the loads acting on the occupants can be reduced.
