Chassis and suspension: The basis for superior handling

Feb 8, 2013
All of the models of the E-Class family will in future be fitted with an electromechanical Direct-Steer system as standard. This combines the speed-dependent power assistance of speed-sensitive steering with a variable ratio across the steering angle range. The power steering assistance provided by the rack and pinion steering gear is controlled on-demand and therefore contributes towards efficiency.  
Advantages of the electromechanical Direct-Steer system:  
  • improved agility thanks to more direct steering response
  • comfortable handling and high levels of steering comfort across all speed ranges
  • considerable savings potential, since energy is only required when steering occurs
  • enables the use of innovative assistance systems, such as Active Parking Assist 
Four suspensions to choose from 
For the E-Class, Mercedes-Benz is offering four refined suspension configurations:  
  • the standard model and ELEGANCE line are fitted with the DIRECT CONTROL suspension with selective damping system, configured for comfort
  • the sportily configured DIRECT CONTROL suspension with selective damping system is positioned 15 mm lower and part of the AVANTGARDE line
  • the DIRECT CONTROL lowered sports suspension is available in conjunction with the Exterior Sports package and AMG Sports package
  • The AIRMATIC air suspension with electronically controlled damping system is fitted as standard on the V8 models. The Estate is fitted as a matter of course with rear-axle air suspension with integrated level control.
On the front axle, the established 3-link front suspension helps to ensure optimum driving dynamics. Both of the links (torque strut and cross strut) in the lower link plane determine the comfortable characteristics of the axle. The third link, the tie rod, forms part of the rack-and-pinion steering system.  
At the rear is the familiar multi-link independent rear suspension, featuring a lightweight design. It provides good wheel control qualities for high levels of comfort and excellent driving dynamics.  
All suspension variants feature impressive sensitivity and ride characteristics and help to ensure a high level of handling safety. 
Excellent braking with ADAPTIVE BRAKE  
The brake system in the E-Class is fitted with the ADAPTIVE BRAKE as standard. Depending on the engine variant, the following braking systems are used on the front axle with internally ventilated brake discs:
  • 1-piston floating brake callipers with different sized brake discs for the 4-cylinder and V6 engine variants
  • 4-piston floating brake callipers for the V8 engine variants
On the rear axle, the E-Class is braked by 1-piston floating brake callipers with different sized brake discs. In the case of the V6 and V8 engine variants, the brake discs are internally ventilated.
All of the engines have a foot-operated parking brake with integrated, automatic cable adjustment. The force applied by the driver is distributed to two additional drum brakes on the rear axle via the brake cable in the centre tunnel. Automatic adjustment helps to reduce the servicing costs.
