Chassis and suspension: Supreme, agile handling

May 9, 2013
Like the Saloon and Estate models, the E-Class Coupé and Cabriolet will be equipped with the electromechanical Direct-Steer system as standard in future. The AGILITY CONTROL suspension, meanwhile, ensures optimum road contact.
The new electromechanical Direct-Steer system combines speed-sensitive power assistance with a steering ratio that varies with the steering angle. This helps to achieve excellent straight-line stability and makes for comfortable handling and high levels of steering comfort across all speed ranges. The electromechanical assistance also offers the potential to make considerable savings by only using up energy when the steering is turned, and also makes innovative assistance systems such as Active Parking Assist possible in the first place. 
Agile, sensitive suspension 
As standard, the Coupé and Cabriolet are fitted with the AGILITY CONTROL suspension with selective damping system. The shock absorbers adapt to changing road surface conditions, thereby ensuring a high level of ride comfort. This also enables sporty handling while still delivering the comfort on long journeys that the brand is renowned for.  
An AGILITY CONTROL sports suspension with selective damping system and firmer damping characteristics is available as an alternative along with the Dynamic Handling package. The latter offers a driving mode setting with sportier accelerator pedal characteristics and gearshift points, as well as electronic damping control. This allows the driver to adjust the damping to their requirements at the touch of a button, depending on whether they want a comfortable or sporty ride.  
A three-link front suspension helps to ensure optimum driving dynamics. The torque strut and cross strut links in the lower link plane are responsible for the axle's comfortable characteristics. The third link, the tie rod, forms part of the rack-and-pinion steering system.  
At the rear is a multi-link independent rear suspension featuring a lightweight design. It provides good wheel control qualities for high levels of comfort and excellent driving dynamics.  
Excellent braking with ADAPTIVE BRAKE  
The brake system on the Coupé and Cabriolet is fitted with ADAPTIVE BRAKE as standard. Depending on the engine variant, the following brake types are used on the front axle with internally ventilated brake discs:  
  • Single-piston floating brake callipers with brake discs of various sizes for the 4-cylinder and V6 engine variants
  • Four-piston floating brake callipers for the V8 engine variants  
The Coupé and Cabriolet are braked at the rear wheels by single-piston floating brake callipers with brake discs of various sizes. 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 cables in the centre tunnel. Automatic adjustment helps to reduce the service costs.
