The C63 AMG suspension includes a redesigned front axle, a reinforced rear axle and widening of the front and rear track. Stiffer elastokinematics, revised axle geometry with more negative camber, and larger rear stabilizer bar sharpen its agility and result in greater lateral acceleration. Additionally, revised spring and damper rates elevate the responsiveness of the suspension while better suppressing road noise and tire vibration.

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]
Adaptive braking technology integrates a suite 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 brake HOLD feature can make long red lights or stopped traffic a little easier.[*5]
Antilock Braking System (ABS)
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 (BAS®)
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]
The first system of its kind, ATTENTION ASSIST continuously monitors different parameters of driving behavior, and can automatically alert the driver with both visual and audible warnings if it detects signs of drowsiness on long trips.

Integrated Restraint System
An advanced system of 9 air bags offers 11-way occupant protection. Dual two-stage front air bags, front side-impact air bags, front pelvic air bags, a driver's knee air bag, and side curtain air bags for both seating rows are standard.[*6]
Side curtain air bags
In a side impact exceeding a preset threshold, a multi-chamber air bag deploys along the front and rear side windows on the affected side of the vehicle. An integrated rollover sensor automatically deploys the ETDs and, if deemed necessary, the side curtain air bags in the event of a detected rollover.[*6]
NECK-PRO front head restraints
In the case of a rear impact exceeding a preset threshold, NECK-PRO front head restraints move forward and slightly upward, reducing the distance between the head restraints and the heads of front-seat occupants. This action helps to reduce the possibility or severity of whiplash-type neck injuries.
Seat belt technology
Arguably our most important passive safety feature, all four outboard 3-point seat belts are equipped with Emergency Tensioning Devices (ETDs) and belt force limiters. If a collision exceeds a preset threshold, ETDs instantly remove slack from the 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.
Occupant Classification System (OCS)
OCS automatically turns the front passenger's front air bag on or off and adjusts the air bag inflation rate based on the weight category determined by weight sensor readings from the front passenger seat.
ISOFIX / Universal LATCH system (Lower Anchors and Tethers for Children)
Standardized child-seat attachments are provided at both rear seating positions. Selectable passenger seat-belt retractors help secure child seats.
Locking & Security
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 all doors plus the trunk and fuel filler.
Locator lighting uses the car's lights to help illuminate a return path when the car is remote-unlocked in darkness. Unlocking the car also activates the illuminated entry system.
Emergency trunk opener
An emergency release lever is located inside the trunk and illuminated for 60 minutes after the trunk lid is closed.
Night Security Illumination
The exterior lights can be programmed to turn on for a preset interval when you remote-lock your vehicle in darkness, to help light a path for you as you leave.
