Performance and Driving Experience of the 2018 Mercedes-AMG CLS 63

Comparative Performance Analysis: CLS 63 vs. CLS 53 vs. CLS 400 4MATIC

• Acceleration (0-60 mph):
  The CLS 63 achieves 0-60 mph in 3.8 seconds, placing it in a league of its own. In comparison, the CLS 53 takes 4.6 seconds, while the CLS 400 4MATIC lags at 5.7 seconds. The V8’s linear power delivery and AMG’s tuned transmission (9-speed automatic with AMG SPEEDSHIFT MCT) ensure rapid shifts and minimal lag, even under aggressive acceleration.
• Quarter-Mile Performance:
  The CLS 63 covers the quarter-mile in 12.0 seconds at 118 mph, outperforming the CLS 53’s 13.2 seconds at 108 mph and the CLS 400 4MATIC’s 14.5 seconds at 98 mph. The higher torque curve of the V8 allows for stronger low-end pull, making it more adept at quick overtakes.
• Braking Performance:
  All three models feature AMG’s high-performance braking system, including 360mm front rotors with 6-piston calipers and 340mm rear rotors with 4-piston calipers. However, the CLS 63’s AMG Braking+ system (optional) enhances stopping power with adaptive brake pressure modulation, reducing distances from 70-0 mph in ~140 feet (vs. ~150 feet for the CLS 53 and ~160 feet for the CLS 400 4MATIC). The CLS 63’s heavier curb weight (4,250 lbs vs. 4,000 lbs for the CLS 53 and 3,800 lbs for the CLS 400) is mitigated by its superior braking hardware.
• Handling Characteristics:
  The CLS 63’s rear-wheel steering (RWS) system and AMG Dynamic Select (with Sport+ mode) enhance agility, particularly in high-speed maneuvers. While the CLS 53 and CLS 400 4MATIC rely on conventional rear-wheel drive (RWD) and AWD (4MATIC), respectively, the CLS 63’s 4MATIC+ all-wheel drive with torque vectoring improves cornering grip by ~15% in slippery conditions. The CLS 63’s stiffer chassis and wider track (62.4 inches vs. 60.2 inches for the CLS 53 and 59.4 inches for the CLS 400) contribute to sharper turn-in and reduced body roll.

The CLS 63’s performance edge stems from its power-to-weight ratio (136 hp/ton), which is 30% higher than the CLS 53 and 70% higher than the CLS 400 4MATIC. This efficiency in power delivery translates to a more engaging driving experience, particularly in spirited or track-oriented scenarios.

Suspension Setup: Adaptive Air Suspension and AMG Ride Control

• Adaptive Air Suspension:
  Unlike the CLS 53 (which uses passive coilovers) or the CLS 400 4MATIC (which offers optional air suspension), the CLS 63’s air springs allow for real-time adjustments via AMG Ride Control. In Comfort mode, the system lowers the car by ~2 inches for a smoother ride, while Sport+ mode raises it slightly to ~1.5 inches for improved cornering stability. The AMG Dynamic Body Control further enhances this by reducing body roll by up to 40% through active anti-roll bars.
• Damping Characteristics:
  The CLS 63’s adaptive dampers feature three pre-set modes (Comfort, Sport, Sport+) and a customizable "Individual" setting. In Sport+ mode, damping stiffens by ~25%, reducing body motion by ~30% compared to standard settings. This setup ensures minimal pitch during acceleration/braking and tight cornering without compromising ride quality on rough surfaces.
• Comparison with CLS 53 and CLS 400 4MATIC:
  The CLS 53’s passive suspension (fixed coilovers) offers less adaptability, leading to a firmer but less refined ride. The CLS 400 4MATIC’s optional air suspension (when equipped) provides height adjustment but lacks the AMG-specific damping calibration, resulting in softer handling and greater body roll. The CLS 63’s system excels in high-speed stability and track-day versatility, making it the most refined yet performance-oriented option.

The CLS 63’s suspension is engineered to minimize the compromise between comfort and sportiness, a feat achieved through electronic damping modulation and active chassis control. This system is particularly effective on highway driving, where it absorbs imperfections while maintaining a flat, planted stance.

Steering System: Electric Power Steering and Variable Ratio

• Electric Power Steering (EPS) Benefits:
  The CLS 63’s EPS system provides instantaneous torque feedback, eliminating the lag associated with hydraulic steering. At low speeds, the steering ratio is 14:1, offering direct, tactile feedback for parking maneuvers. As speed increases, the ratio progressively stiffens to 18:1, ensuring high-speed stability without requiring excessive effort.
• Variable Ratio and Driver Engagement:
  Unlike the CLS 53 (which uses a fixed-ratio hydraulic system) or the CLS 400 4MATIC (which has a softer EPS feel), the CLS 63’s adaptive steering adjusts based on vehicle speed, throttle position, and steering wheel angle. This results in:
  
• Enhanced precision in city driving
