   Driving Dynamics and Handling Characteristics of the Mercedes-AMG CLS 63 (2020)

   The Mercedes-AMG CLS 63 (2020) embodies a harmonious blend of luxury, performance, and cutting-edge engineering, delivering a driving experience that prioritizes both agility and stability. Its chassis tuning is meticulously optimized to balance the demands of high-speed stability with the precision required for dynamic cornering. The integration of AMG-specific technologies, such as adaptive dampers, rear-axle steering, and Dynamic Stability Control (DSC), ensures that the vehicle adapts seamlessly to varying road conditions while maintaining a commanding presence on the road. These features are complemented by the 4MATIC+ AWD system, which enhances traction and control without compromising the vehicle’s sporty character. Below, the technical underpinnings and performance metrics of the CLS 63 AMG’s driving dynamics are explored in detail.
   

   Chassis Tuning and AMG-Specific Components

   The CLS 63 AMG’s chassis is engineered to optimize body control, weight distribution, and ride comfort while maximizing performance. The AMG Dynamic Select system integrates adaptive dampers that adjust stiffness in real-time based on road surface conditions, driver input, and vehicle dynamics. These dampers feature dual-flow technology, allowing for independent compression and rebound tuning, which enhances both cornering stability and comfort during high-speed maneuvers.

   The rear-axle steering (RAS) system further refines handling by dynamically adjusting the rear wheels’ steering angle up to ±2.5 degrees depending on vehicle speed and trajectory. This innovation reduces understeer during aggressive cornering while improving straight-line stability at high velocities. Additionally, the Dynamic Stability Control (DSC) system employs electronic differential locks and torque vectoring to mitigate wheel slip, ensuring optimal power delivery to all four wheels. The AMG Ride Control system also incorporates active body control, which minimizes body roll by up to 70% in dynamic situations, preserving the vehicle’s aerodynamic efficiency and occupant comfort.
   

   Functionality of the 4MATIC+ AWD System

   The 4MATIC+ AWD system in the CLS 63 AMG is designed to deliver all-weather traction and performance-oriented power distribution without sacrificing the vehicle’s sporty character. Its operation can be broken down into the following key phases:

   1. Torque Distribution Under Normal Conditions
   

6. Under standard driving conditions, the system defaults to a front-biased torque split (60% front, 40% rear) to optimize fuel efficiency and reduce mechanical complexity.
7. The electronic limited-slip differential (eLSD) in the front axle ensures balanced power delivery between the front wheels, minimizing wheel spin during acceleration.

2. Dynamic Torque Vectoring for Enhanced Traction


8. When wheel slip is detected (e.g., during hard acceleration or cornering), the system automatically redistributes torque to the rear axle via the rear eLSD, increasing rear-wheel torque to up to 70% for improved traction.
9. The torque vectoring by braking (TVB) function selectively applies brakes to individual wheels to counteract understeer or oversteer, enhancing stability without relying solely on mechanical differentials.

3. Off-Road and Low-Grip Scenarios


10. In low-traction conditions (e.g., snow, gravel, or wet surfaces), the system engages full-time 40:60 torque distribution with adaptive torque bias, prioritizing the wheel with the highest grip.
11. The hill descent control (HDC) feature activates when descending steep gradients, applying selective wheel braking to maintain a controlled speed without relying on the driver’s input.

4. Performance Mode Integration


12. In Sport or Sport+ modes, the system temporarily shifts to a rear-wheel-biased distribution (30% front, 70% rear) to enhance launch stability and cornering precision.
13. The AMG Dynamic Plus setting further optimizes torque delivery by reducing latency in the AWD system, ensuring instantaneous response during aggressive driving.

Steering Feel and Responsiveness: A Comparative Analysis

The CLS 63 AMG’s steering system is a servo-electric power steering (EPS) unit with variable ratio assistance, calibrated to provide direct, weighty feedback at low speeds and effortless precision at high velocities. The steering wheel features a flat-bottom design with haptic feedback, offering a tactile connection to the road that is both informative and engaging.

When compared to the E63 S Sedan, the CLS 63 AMG’s steering exhibits subtle yet meaningful differences:


The CLS 63 AMG’s steering is slightly more turn-in sensitive than the E63 S, thanks to its longer wheelbase (3.08m vs. 2.97m) and rear-axle steering system, which enhances agility in mid-corner maneuvers. The E63 S, however, delivers a more linear and progressive feel due to its shorter wheelbase and stiffer front suspension, making it feel more directly connected to the driver’s inputs during hard braking and throttle application.
In terms of high-speed stability, the CLS 63 AMG’s steering is more forgiving due to its adaptive damping and torque vectoring, reducing the need for constant corrections on uneven surfaces. Both vehicles share the same 14:1 steering ratio, but the CLS 63 AMG’s rear-axle steering introduces a subtle self-aligning torque that enhances corner exit smoothness, a characteristic less pronounced in the sedan’s more rigid setup.

Cornering and Braking Performance Metrics

The CLS 63 AMG’s chassis tuning and high-performance braking system deliver exceptional lateral grip and short stopping distances, as evidenced by the following metrics:


Scenario	Performance Data
Lateral Grip (Dry Asphalt)	0.92g (combined with AMG Dynamic Plus and Sport+ mode) 0.88g (standard Sport mode) Achieved through low-profile 275/35 R21 AMG tires, adaptive dampers, and active body control
Braking Performance (Dry Asphalt, 100 km/h → 0 km/h)	33.5 meters (with AMG Brake System and one-pedal driving) 35.2 meters (standard braking without one-pedal integration) Enabled by 380mm front ventilated discs, 360mm rear discs, and 6-piston AMG monoblock calipers
Braking Performance (Wet Asphalt, 80 km/h → 0 km/h)	42.8 meters (with DSC and ABS) 46.1 meters (without electronic intervention) Electronically controlled brake distribution (EBD) and cornering brake control (CBC) enhance stability
Steering Lock-to-Lock (3.6 turns)	2.9 turns (full lock at 10 km/h) Reduced to 2.4 turns (at 80 km/h due to variable ratio steering) Enhances parking maneuverability while maintaining high-speed precision
