C 55 AMG Chassis

The new AMG sport chassis makes a significant contribution to boosting the dynamic handling. Springs with a 20 per cent higher rigidity, harder gas shock absorbers with degressive characteristics and a bigger stabilizer on the rear axle (only in the C 55 AMG estate) not only make the most of out of the road but also reduce the body roll that happens when a car drives rapidly through a curve and the roll angle in alternating curves.
The elastokinematics were reworked on both axles: Both the tension strut on the McPherson three-link front axle and the spring suspension link of the multi-link independent rear suspension are harder. As a result, driving through curves becomes much more precise. The noticeable gains in steering precision and spontaneity have been achieved without any noticeable loss in suspension comfort.
Dynamic-handling control systems comprehensively overhauled
When a car enters a curve at high speed, the system determines when the back tyre on the inside part of the curve starts to slip and can brake it to a precisely calculated degree. The effect that is created corresponds to that of a mechanical locking differential and promotes the traction of the driven wheels.
Even when shut off, the ESP® recognizes a potentially unstable driving situation, for example when the driver suddenly applies the brakes. Within milliseconds, the ESP is completely available again. A potential accident can thus be prevented. What’s more, the control processes in all operating conditions have been made more harmonious.
Steering ratio now seven percent more direct
The new 18-inch AMG light-alloy, double-spoke wheels being used as standard equipment for the first time in the C-Class create a spontaneous, dynamic form of handling. The front axle has tyres in the 225/40 ZR 18 format on 7.5-inch-wide rims. On the back the dimensions are 245/35 ZR 18 on 8.5-inch-wide rims. The track of the front axle has been expanded by 14mm, improving driving stability and steering behaviour.
The robust AMG high-performance braking system guarantees a high degree of driving safety. Large, inner-ventilated disc brakes on the front and rear axles — the front discs are also perforated — enable first-class braking deceleration. When the brakes are fully applied at 100 km/h, the C 55 AMG comes to a halt in fewer than 36m.
