Mercedes S – Class- The first time of the drivers rear

As tradition requires, the new series of the Mercedes S-Class will bring the debut of numerous technological devices destined to leave their mark in the auto industry. And after having elaborated on the theme of infotainment and user interface with the presentation of My Mbux, the House of Stuttgart has let it be known the new details to the account of the next flagship: those related to security. One of the horses of battle of the Sonderklasse, from the time of the airbag in 1981, and the Esp of 1995.

Airbags in the rear and Impulse Side. The new model, which will be unveiled in September and will go on sale between the end of 2020 to early 2021, will be the baptism of two more world premieres in this field: the airbags in the rear, Pre-Safe Impulse Side.

Attention to those seated behind. “The drivers rear is another first for the automotive industry held to baptism by the S-Class”, emphasizes Michael Hafner, head of the autonomous guide of the German House. The device, unveiled last year on the Experimental Safety Vehicle 2019 reflects the attention paid by the designers in respect of the rear passengers, in the same way as it is in My Mbux, infotainment system that sits behind it offers three screens, moreover, with the same capabilities as the earlier ones.

A cushion of air (not gas). The airbags in the rear, however, are not a simple transposition of conventional ones: here is not the entire cushion to be inflated at the time of the explosion, but only two support structures at the sides, which enclose an inner part that expands is not due to the gases of the primer, but the exact amount of air that is specifically absorbed by the passenger compartment.

Is a drivers flexible. The pillows are more flexible than the front ones, also because of the different emergency situations in which they are to be deployed: “While in front of sit usually an adult passenger behind you can also find kids and child seats, and therefore the possible scenarios are much more diverse: we need a structure that can embrace the subject to be protected, rather than impattarci in the conventional way,” explains Hafner.

He stands eight inches. The introduction of the new E-Active Body Control – turning to the field of preventive security, has allowed us to improve also the Impulse function Side of the Pre-Safe. “By leveraging the information collected by the radar vehicle, Pre-Safe Impulse Side allows you to identify an impending impact and to raise the vehicle to 80 millimeters,” explains the engineer, “allowing in this way to protect the occupants more effectively, dissipating the impact with a portion rigid body, such as the brancardo”.

The seats move. In addition to avoid that the energy of the impact is absorbed by the goalkeeper, thus reducing the deformation of the body, and facilitating the exit of the occupants of the vehicle after an accident, the Impulse Side puts in place also has a second task: that of inflating a cushion of air under the front seats, moving them towards the center of the passenger compartment and further decreasing the risk of injury to those on board.

The rear axle steering. E-the Active Body Control makes it possible to also an improvement of the driving comfort: the management of each individual wheel, has allowed the introduction of rear axle steering, which makes it more agile manoeuvres at low speed (under 60 km/h), turning counter-phase with respect to the front wheels, and increases the stability in the corners at high speeds, steering in the same direction as the front axle.

Parking (but not only) stand-alone. The steering angle of the rear, in both cases, up to a maximum of 10°, by placing the turning radius of the next S-Class to two metres below the value of the previous generation, and therefore very close to that of the more compact Home, Class A: a characteristic that, combined with the new Active Parking Assist, promises parking manoeuvres extremely simple. And that is only an appetizer, emphasizes the House, the functions of autonomous guide of its new flagship.
