The Mercedes-Benz CLS 63 AMG has long been synonymous with breathtaking performance blended with luxurious coupe styling. For the 2014 model year, Mercedes-AMG elevated this benchmark even further, introducing not only performance enhancements to the existing CLS 63 AMG but also unveiling an entirely new, more potent variant: the CLS 63 AMG S-Model. This article delves into the specifics of these high-performance machines, focusing on what makes the Mercedes Cls 63 a standout in its class, especially for enthusiasts and those considering performance upgrades.
Enhanced Performance and the Introduction of the S-Model
Mercedes-AMG’s commitment to pushing boundaries is clearly demonstrated with the 2014 CLS 63 AMG lineup. At the heart of these models lies the formidable AMG 5.5-liter V8 biturbo engine (M157), an engineering marvel celebrated for its exceptional balance of raw power and surprising efficiency. For the standard CLS 63 AMG, this engine delivers an impressive 550 horsepower and 531 lb.-ft. of torque. However, the spotlight shines brightest on the new S-Model, which takes performance to another level.
The CLS 63 AMG S-Model is engineered for drivers who demand the ultimate in performance. It boasts an uprated version of the AMG 5.5-liter V8 biturbo, churning out a staggering 577 horsepower and 590 lb.-ft. of torque. This power surge isn’t just about bragging rights; it translates to tangible improvements in acceleration and overall driving dynamics. The S-Model also introduces the performance-oriented AMG 4MATIC all-wheel drive system, ensuring that all that power is effectively translated to the road.
AMG 4MATIC: Mastering Power Delivery
Recognizing the growing demand for enhanced traction and control in high-performance vehicles, Mercedes-AMG developed a specialized version of their 4MATIC all-wheel drive system. This isn’t your everyday all-wheel drive; it’s engineered specifically for sporty driving dynamics. The AMG 4MATIC system, now standard on the CLS 63 AMG models, including the S-Model, provides a level of grip and performance previously unseen in this vehicle segment.
This performance-oriented system distributes engine torque with a rear-biased split of 33:67 between the front and rear axles. This configuration is crucial for maintaining the characteristic AMG rear-wheel-drive feel while offering the added security and acceleration benefits of all-wheel drive. The result is exhilarating driving fun with enhanced handling, especially when exiting corners or in challenging road conditions. The integration of a 3-stage ESP® system, specifically calibrated for the AMG 4MATIC, further optimizes handling and control. In “SPORT Handling” mode, the Torque Vectoring Brake subtly applies braking force to individual wheels, enhancing agility and providing neutral steering response during поворотах.
The Potent AMG 5.5-Liter V8 Biturbo Engine
The M157 engine, the heart of the Mercedes CLS 63 AMG, is a testament to AMG’s engineering prowess. This 5.5-liter V8 biturbo engine stands out for its remarkable efficiency, delivering high performance without compromising fuel economy – a rare feat in the high-performance segment.
In the CLS 63 AMG S-Model, the engine enhancements are achieved through refined engine electronics and increased turbo boost pressure, bumped from 0.9 to 1.0 bar. This seemingly small increase makes a significant difference, contributing to the 27 horsepower jump over the standard model (and a substantial 32 horsepower increase compared to the predecessor CLS 63 AMG). Despite the power boost, AMG engineers have maintained impressive fuel efficiency and low emissions across the CLS 63 AMG range, solidifying the M157’s position as the most efficient high-performance V8 engine in production at the time.
AMG SPEEDSHIFT MCT 7-Speed Sports Transmission
Complementing the powerful engine is the AMG SPEEDSHIFT MCT 7-Speed sports transmission. This transmission is not just about shifting gears; it’s about providing a tailored driving experience. It offers four distinct drive programs: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus), and “M” (Manual).
In “C” mode, the focus is on smooth, comfortable driving with early upshifts and the ECO start/stop function activated to enhance fuel efficiency. In contrast, “S,” “S+,” and “M” modes sharpen the engine and transmission response, delivering noticeably more agile performance and disabling the ECO start/stop. For the truly enthusiastic driver, these modes offer rapid gear changes, accompanied by an exhilarating sound, thanks to momentary suppression of ignition and injection during full-throttle shifts. Standard features like automatic rev-matching on downshifts and RACE START further underscore the transmission’s performance pedigree.
Chassis and Handling Dynamics
The Mercedes CLS 63 AMG is engineered to handle its immense power with precision and agility. All models are equipped with AMG Adaptive Sports Suspension featuring electronically controlled damping. Drivers can choose between “Comfort,” “Sport,” and “Sport Plus” settings with a simple button press in the AMG DRIVE UNIT, adapting the suspension characteristics to their driving preferences and road conditions. The front suspension utilizes a steel-spring system, while the rear axle features a load-leveling air suspension system, ensuring a balance of comfort and performance.
The S-Model and the standard CLS 63 AMG with all-wheel drive receive further chassis optimizations. Newly developed aluminum control arms in the front suspension enhance grip, agility, and steering neutrality during high-speed cornering. The S-Model takes it a step further with performance-oriented elastokinematics, providing even more neutral handling and enhanced feedback at the limits of performance. A wider front track and increased negative camber on all wheels contribute to improved cornering prowess and road feel. AMG’s electromechanical speed-sensitive steering, with a direct 14:1 ratio, ensures agile handling and variable power assist that adapts to the selected suspension mode.
S-Model Exclusive Features: Elevating Performance Further
The CLS 63 AMG S-Model distinguishes itself with several exclusive features designed to amplify its performance capabilities and visual appeal. A standard limited-slip rear differential is a key upgrade for the S-Model. This mechanical component significantly enhances traction, particularly on the racetrack, allowing for more aggressive power application during cornering and improved vehicle dynamics overall.
Visually, the S-Model is identifiable by its red brake calipers and the “S” designation in contrasting black on the AMG logo on the trunk lid. Inside, the S-Model boasts a black premium nappa leather interior with contrasting gray stitching, silver seat belts, and an AMG Performance steering wheel with Alcantara® grip areas. The AMG crest embossed on the front head restraints and unique “S AMG” badging on the instrument cluster further set the S-Model apart.
For braking, while the standard CLS 63 AMG features a high-performance AMG braking system, the S-Model offers an optional AMG ceramic composite brake system. These larger ceramic discs provide superior heat resistance, extended service life, and a 40% weight reduction, further enhancing handling and agility.
Premium Audio Experience: Bang & Olufsen BeoSound AMG
Beyond performance, the Mercedes CLS 63 AMG also caters to audiophiles. An optional Bang & Olufsen BeoSound AMG high-end surround sound system, co-developed with the renowned Danish audio specialist, delivers an unparalleled in-car audio experience. This system boasts a 1,200-watt amplifier, 14 high-end speakers, and Dolby Digital 5.1 playback capability. The integrated digital sound processor (DSP) allows for customized sound settings, including a “True Image™” mode for realistic sound at any listening position and preset sound modes for “Reference” studio sound or immersive surround sound. Illuminated tweeters with acoustic lens technology and high-end speaker covers further enhance the system’s premium appeal.
Conclusion: The Pinnacle of Performance Coupes
The 2014 Mercedes-Benz CLS 63 AMG and CLS 63 AMG S-Model represent the zenith of performance coupes, blending breathtaking power, sophisticated handling, and luxurious appointments. The S-Model, in particular, stands as a testament to AMG’s relentless pursuit of performance excellence, offering a driving experience that is truly in a class of its own. For those seeking a vehicle that seamlessly merges high-octane thrills with everyday usability and luxury, the Mercedes CLS 63 AMG, especially in its S-Model guise, remains an exceptional choice. Its combination of potent V8 power, advanced AMG 4MATIC all-wheel drive, and meticulously engineered chassis and features ensures an engaging and rewarding driving experience, solidifying its position as a leader in the high-performance coupe segment.
