The Elegant Evolution: A Journey Through the Mercedes-Benz CLS Saga
The Mercedes-Benz CLS. The name itself conjures images of sleek lines, sophisticated luxury, and a distinctive blend of coupe-like dynamism with sedan practicality. More than just a car, the CLS carved out a niche for itself, pioneering the “four-door coupe” segment and proving that automotive design could be both aesthetically thrilling and commercially successful. Its journey through the years is a testament to Mercedes-Benz’s commitment to innovation, style, and the relentless pursuit of automotive excellence. Let us embark on a detailed exploration of the CLS’s evolution, tracing its lineage from its groundbreaking debut to its current iteration.
The Genesis of a Legend: The First Generation (C219, 2004-2010)
The story of the CLS begins in the early 2000s, a time when the automotive landscape was ripe for a bold new concept. Mercedes-Benz, always a pioneer in segment creation, envisioned a sedan that possessed the alluring silhouette of a coupe. This vision culminated in the 2004 Mercedes-Benz CLS (C219), a car that immediately turned heads and redefined automotive styling.
The C219 was built upon the platform of the E-Class, but its design was a radical departure. It featured a dramatically sloping roofline, frameless doors, and muscular, flowing bodywork that exuded a sense of athletic elegance. This wasn’t just a stylistic exercise; it was a statement of intent, demonstrating that a four-door vehicle could be as desirable and sporty as a two-door coupe.
Models and Trim Levels (C219):
- CLS 350: Launched as the entry-level model, it was powered by a 3.5-liter V6 engine producing around 268 horsepower. Available trims focused on comfort and luxury, with standard features like leather upholstery, automatic climate control, and a premium sound system. Options included advanced navigation, adaptive cruise control, and ventilated seats.
- CLS 500: This model offered a more potent 5.0-liter V8 engine, producing approximately 302 horsepower. It typically came with enhanced interior appointments, larger alloy wheels, and a more sophisticated suspension setup. Options mirrored those of the CLS 350 but often included higher-end audio systems and more advanced driver assistance features.
- CLS 55 AMG (2004-2006): The AMG division injected its potent magic into the CLS, creating the CLS 55 AMG. This beast was powered by a supercharged 5.4-liter V8 engine, delivering a formidable 469 horsepower and a massive 516 lb-ft of torque. Performance was paramount, with AMG-tuned suspension, brakes, and exhaust systems. Exterior enhancements included a more aggressive body kit and distinct AMG wheels.
- CLS 63 AMG (2006-2010): As the C219 evolved, the CLS 55 AMG was replaced by the CLS 63 AMG. This model featured a naturally aspirated 6.2-liter V8 engine, producing an impressive 507 horsepower and 465 lb-ft of torque. While slightly less torquey than its predecessor, it offered a more linear power delivery and a higher redline. The CLS 63 AMG continued the legacy of AMG performance with enhanced chassis dynamics and braking capabilities.
- CLS 320 CDI (Diesel, 2005-2010): For European markets and those prioritizing fuel efficiency, Mercedes-Benz offered the CLS 320 CDI. This diesel variant featured a 3.0-liter V6 turbodiesel engine, delivering around 221 horsepower and a significant amount of torque. It offered a compelling blend of performance and economy, solidifying the CLS’s appeal across a wider range of buyers.
The first generation CLS was a resounding success, praised for its unique styling, luxurious interior, and refined driving experience. It proved that Mercedes-Benz could still innovate and capture the imagination of car enthusiasts.

A Sharper Silhouette: The Second Generation (C218, 2011-2018)
Following the groundbreaking debut of its predecessor, the second generation CLS, the 2011 Mercedes-Benz CLS (C218), arrived with a refined and slightly more aggressive interpretation of the four-door coupe formula. While still instantly recognizable as a CLS, the C218 featured sharper lines, a more defined shoulder line, and a sportier stance. The dramatic roofline remained a defining characteristic, but the overall design felt more contemporary and athletic.
The C218 was based on the then-current E-Class platform, but it moved further away in terms of styling and driving dynamics. The interior also saw significant upgrades, with a focus on premium materials, advanced technology, and a driver-centric cockpit.
Models and Trim Levels (C218):
- CLS 350: The V6 engine remained, with updates to improve efficiency and performance, typically around 302 horsepower. Trim levels offered a high level of standard luxury, with options for advanced infotainment systems, premium sound, and sophisticated driver assistance packages.
- CLS 500/CLS 550 (depending on market): This model featured a more powerful 4.7-liter twin-turbocharged V8 engine, producing around 402 horsepower. This engine offered a significant boost in performance and torque, further enhancing the CLS’s grand touring capabilities.
- CLS 63 AMG (2011-2014): The AMG variant initially retained a naturally aspirated 6.2-liter V8 engine, but soon transitioned to a more powerful 5.5-liter twin-turbocharged V8. This engine delivered a staggering 518 horsepower in standard guise and an optional “S-Model” pushed this to 550 horsepower. The CLS 63 AMG was a true performance machine, boasting incredibly potent acceleration and razor-sharp handling, with extensive chassis and braking upgrades.
- CLS 63 AMG S-Model (2014-2018): The S-Model designation became more prominent, signifying the pinnacle of CLS 63 AMG performance. These models featured increased power output, often with the 7-speed AMG SPEEDSHIFT MCT transmission, and further enhancements to the suspension and braking systems for a more track-focused feel.
- CLS 250 CDI/CLS 220 CDI (Diesel, depending on market): Further evolution of the diesel engine saw the introduction of more efficient and powerful options, such as the 2.1-liter four-cylinder turbodiesel in the CLS 220 CDI (around 170 horsepower) and the 3.0-liter V6 turbodiesel in variants like the CLS 350 CDI (around 261 horsepower). These diesel models offered excellent fuel economy without compromising on the CLS’s premium feel and comfortable ride.
- CLS Shooting Brake (X218, 2012-2018): A significant and exciting addition to the second generation was the CLS Shooting Brake. This unique body style retained the sleek, coupe-like profile but added a more practical wagon-like rear end, offering increased cargo space and versatility. It was available with many of the same engine and trim options as the CLS coupe, further broadening the CLS’s appeal.
The C218 generation solidified the CLS’s position as a desirable and stylish alternative to traditional luxury sedans. Its blend of aggressive styling, sophisticated technology, and potent performance, particularly in AMG guise, ensured its continued success.
The Third Act: The Modern Era (C257, 2018-Present)
The third and current generation CLS, the 2018 Mercedes-Benz CLS (C257), represents a further evolution of the four-door coupe concept. While still unmistakably a CLS, the C257 adopts a more flowing and sensual design language, emphasizing elegance and aerodynamic efficiency. The iconic sloping roofline remains, but it is integrated with a smoother, more sculpted body. The front end features a distinctive diamond-look grille and sharp LED headlights, while the rear boasts slim, wraparound taillights.
The interior of the C257 is a significant leap forward in terms of technology and luxury. It adopts Mercedes-Benz’s latest interior design philosophy, featuring a widescreen digital cockpit, sophisticated ambient lighting, and a focus on opulent materials.
Models and Trim Levels (C257):
- CLS 350 d / CLS 400 d (Diesel): These models offer powerful and efficient diesel engines. The CLS 350 d typically features a 3.0-liter inline-six turbodiesel with around 282 horsepower, while the CLS 400 d offers a more potent version of the same engine, producing around 335 horsepower.

It features a 3.0-liter inline-six engine with EQ Boost, producing a combined output of around 429 horsepower. The “4MATIC+” designation signifies an advanced all-wheel-drive system that can dynamically distribute power. The CLS 53 AMG offers a thrilling driving experience with AMG-specific suspension, brakes, and styling elements.
- CLS 450 4MATIC (facelift): Following a facelift, the CLS 450 4MATIC continues with its electrified inline-six engine, often with minor power adjustments and updated styling cues.
