BETTER VIEW OF THE REAR-AXLE STEERING OF THE S-CLASS
With the new S-Class, Mercedes-Benz is offering rear-axle steering for the first time, which is basically available in two different versions: with 4.5 degrees and with up to 10 degrees steering wheel adjustment. The variant is available for both the S-Class long and short versions, as well as in the new Maybach model.
Rear axle steering with a steering angle of up to 10 degrees
With the rear-axle steering with a steering angle of up to 10 degrees, Mercedes-Benz demonstrates its claim to leadership - even when parking. The vehicle looks almost as handy as a compact car when maneuvering. At higher speeds, you use the sovereignty of the long wheelbase.
At speeds of less than 60 km/h, the rear wheels steer in the opposite direction to the front wheels - when parking by up to 10°
against the front axle angle. Depending on the situation, the wheelbase is virtually shortened, making the vehicle more manoeuvrable, nimble and agile. You can also feel it when turning, changing direction quickly and maneuvering.
Steering from 60 km/h in the same direction
From a speed of more than 60 km/h, the rear wheels steer up to 3°
in the same direction as the front wheels. The resulting virtual longer wheelbase offers noticeable advantages: increased driving stability and driving safety at high speeds, quick lane changes or sudden evasive maneuvers.
In addition, significantly less steering angle has to be applied during dynamic maneuvers, such as when driving on a country road - and the vehicle reacts more sportily to steering commands. This function is implemented via the integrated driving dynamics control of the ESP.
The components of the system:
- four speed-dependent steering strategies:
- Parking with a strong turning circle reduction (up to 10° steering angle opposite to the front axle) by almost two meters
- City maneuverability (up to 4.5° steering angle opposite to the front axle), active up to approx. 60 km/h
- High speed stabilization (up to 2.5° steering angle in the same direction as the front axle)
- Driving dynamics increase (up to 3° steering angle in the same direction or opposite to the front axle, depending on the driving situation), active from approx. 60 km/h, controlled by the integrated driving dynamics control of the ESP.
- Snow chain mode for the adapted control of the rear axle steering in wintry conditions with a maximum steering angle of the rear axle of 4.5°
- The rear axle steering is presented in the central display
- Representation of the current rear axle steering angle
- Display of the current lane circle when parking
- Steering ability of the rear axle via an electromechanical central actuator with trapezoidal thread
In the future, Mercedes-Benz will also offer
rear-axle steering in other model series - also below the luxury class, but with different designs and steering angles. More about this with us in a few weeks.
