Chassis and Traction Control/Stability Systems

  • Chassis
  • Multlink suspension

    The 4-wheel independent multilink suspension is key to the exceptional poise and control of the CL550. The 5-arm rear multilink design, a Mercedes-Benz innovation, controls rear-wheel movement with outstanding precision. For more precise and predictable handling, the front suspension and steering gear are mounted to the body structure via a rigid subframe.

  • Direct-steer system

    Direct-steer automatically varies the steering ratio based on how far you turn the steering wheel. It provides quicker steering and lighter effort while parking while maintaining excellent directional stability and crisp feedback at higher speeds.

  • Steering type

    Direct-Steer Speed Sensitive Rack and Pinion Steering

  • Turning circle

    38.2 ft.

  • Traction Control & Stability
  • Electronic Stability Program (ESP)

    This safety breakthrough first introduced by Mercedes-Benz continually monitors your driving inputs and the vehicle's motion to help keep it going in your intended direction, especially in corners and during evasive maneuvers. If it detects wheelspin, severe understeer (plowing), or oversteer (fishtailing), ESP can brake individual wheels and reduce engine power to help bring the vehicle under control.[*4]

Brakes, Wheels, and Tires

  • Brakes
  • Adaptive brakes

    Powerful 4-wheel disc brakes feature a number of advances. If you lift off the accelerator quickly, Predictive Brake Priming sets the pads closer to the discs for more immediate response when you apply the brakes. In the rain, Automatic Brake Drying periodically applies the brakes just enough to sweep water build-up from the discs. During uphill starts, Hill-Start Assist helps prevent unwanted rollback. And a HOLD feature can make long red lights or stopped traffic a little easier.[*5]

  • Antilock Braking System (ABS)

    The Antilock Braking System (ABS) senses impending wheel lockup under heavy braking and pumps the front brakes individually or the rear brakes together. This intelligent system can pump the brakes as needed up to 30 times per second, to prevent lockup and preserve the driver's steering ability.[*5]

  • Brake Assist

    Brake Assist senses emergency braking via the speed at which the driver presses the brake pedal and immediately applies maximum available power boost. Brake Assist can potentially reduce the overall stopping distance by eliminating the delay caused by a common human tendency not to brake hard enough, soon enough. Letting up on the brake pedal releases Brake Assist.[*5]

  • Wheels/Tires
  • Wheels

    18" 5-spoke (8.5 x 18.0)

  • Tires

    255/45 R18 all-season

Safety and Security Systems

  • Restraint Systems
  • 11-way air bag protection

    An advanced system of 9 air bags offers 11-way occupant protection. Dual two-stage front air bags, front and rear side-impact air bags, a driver's knee air bag, and window curtain air bags for both seating rows are standard.[*6]

  • Seat belt technology

    Equipped with Emergency Tensioning Devices (ETDs) and belt force limiters, 3-point seat belts are arguably our most important passive safety feature. If a collision exceeds a preset threshold, the ETDs instantly remove slack from the front and rear seat belts. Belt force limiters allow a slight amount of give in the seat belts, to reduce the peak seat-belt forces on the occupant. Front seat belts are attached directly to each front seat, for optimal positioning and ease of use.

  • Locking & Security
  • SmartKey

    The SmartKey remote control integrates remote door locks and trunk opener, a removable valet key, and a remote panic alarm. You may selectively unlock only the driver's door and fuel filler, or both doors plus the trunk and fuel filler.

  • Mercedes-Benz mbrace

    From your car, online or via the mbrace Mobile Application on your compatible smartphone, mbraceĀ® helps keep you connected with nearly 20 different security, destination planning and convenience services. Combining advanced technology with 24-hour support from helpful experts, two available service packages can help you plan a trip, remember where you parked, or even handle an unexpected emergency. Every new Mercedes-Benz equipped with mbrace includes a complimentary 6-month trial subscription.[*7,*8,*9]

  • Antitheft alarm system

    The standard antitheft alarm system is armed automatically when you lock your Mercedes from the outside. It sounds the horn and flashes the exterior lights if a door, the trunk or the hood is opened without first unlocking the vehicle. You can also sound the alarm by pressing the red "panic" button on your SmartKey remote when you're within range of your vehicle.
