In the CLS innovative suspension components ensure the greatest possible ride comfort. The DIRECT CONTROL suspension, adjusted for optimum comfort, guarantees top-level comfort on long journeys as standard for the 4- and 6-cylinder models.
The optional electronically-regulated AIRMATIC suspension with ADS adaptive damping system and all-round self-levelling (standard for CLS 500 BlueEFFICIENCY and CLS 500 4MATIC BlueEFFICIENCY) provides a sporty driving experience
DIRECT CONTROL suspension with comfort tuning
The DIRECT CONTROL suspension, adjusted for optimum comfort, guarantees top-level comfort on long journeys as standard for the 4- and 6-cylinder models). The suspension with selective damping system combines agility with ride comfort. The vibration dampers adapt automatically in line with the current driving situation, thus enhancing both damping and the car’s stability – even on poor road surfaces. The DIRECT CONTROL suspension can also be optionally configured for out-and-out sports performance.
Direct steering with variable servo assistance and variable steering ratio
Direct steering with variable servo assistance comprises two components: speed-sensitive power assistance which is already known from the speed-sensitive steering function, and a variable steering ratio which is dependent on the steering wheel angle. Together these components make for comfortable manoeuvring at low speeds and also stable straight-line stability at higher speeds.
AIRMATIC air suspension with adaptive damping system and all-round self-levelling (optional), 
AIRMATIC provides ride comfort and driving dynamics at the highest level. The air suspension system works in combination with a fully automatic damping adjustment which continually adjusts to the driving situation and provides excellent road roar and tyre vibration characteristics even when the road is only slightly bumpy. In addition the vehicle can be raised on poor or unfavourable stretches of road to increase ground clearance. When driving continually at a high speed the vehicle is automatically lowered. This improves handling and reduces wind resistance - an additional contribution to reducing fuel consumption.
Lowered sports suspension(optional)
The sports suspension enhances the dynamic appearance of the vehicle, while the tauter suspension and damper settings make an even sportier driving style possible without major loss of ride comfort.
