The allure of a V12 engine is undeniable. The first time I heard the raw power of a straight-piped V12, it was a sound that resonated deeply, planting a seed of aspiration. The dream was simple: to one day experience that power firsthand. That aspiration materialized in the form of the 2005 Mercedes-Benz CL600.
Under the hood of this 2005 Mercedes CL600 resides the magnificent Mercedes-Benz M275 5.5L twin-turbo V12 engine. While it boasts around 500 horsepower, the true marvel of this engine is its immense torque, delivering a staggering 600 lb-ft. Initially, the search began for a naturally aspirated V12 from the 1990s, the M120. However, finding a model of that era in good condition with low mileage proved challenging. Furthermore, the modern twin-turbo V12 offered a significant leap in power and responsiveness compared to the older, albeit reliable, M120. Exploring alternatives from BMW and other luxury brands, none quite captured the appeal of a Mercedes-Benz. The pull of the three-pointed star, especially with a V12, was simply too strong.
The desire for this engine extended across several Mercedes-Benz models: the S600, the SL600, and ultimately, this CL600. While the high-performance AMG 65 versions were tempting, they resided just outside the desired budget. The S-Class sedan was a practical choice, but already owning a comfortable and fuel-efficient sedan for family trips made it less appealing. The SL convertible offered open-top thrills, but its lack of rear seats limited its practicality for family outings. The CL600 emerged as the ideal compromise. Its long coupe silhouette provided a distinct style compared to other cars in the garage. Despite the rear seats being compact, they are surprisingly usable for shorter journeys, making it a more versatile option.
This 2005 Mercedes CL600 embodies the spirit of a classic muscle car, albeit with a distinct layer of German refinement. It’s a large, rear-wheel-drive hardtop coupe that unapologetically consumes fuel and possesses the capability to easily overwhelm its tires. Think of the grand American personal luxury coupes of the late 1950s and 60s – the Ford Thunderbird, Pontiac Grand Prix, Buick Riviera, Cadillac Eldorado. These were vehicles defined by their imposing size, powerful engines, and a generous array of luxury features and innovative technology. The CL600 echoes this lineage with its long, elegant lines, pillarless coupe design, and powerful presence.
However, unlike its American muscle car ancestors, the 2005 Mercedes CL600 integrates modern engineering to deliver a driving experience that is both exhilarating and composed. Despite weighing close to 4500 lbs and utilizing a conventional automatic transmission, the Active Body Control (ABC) hydraulic suspension keeps the car remarkably level through corners and effortlessly absorbs road imperfections. While the weight is always perceptible, the car turns in with precision, though the tires will eventually surrender to the vehicle’s considerable mass when pushed to its limits. The standard CL brakes, equipped with substantial 4-piston calipers and ventilated rotors, are powerful, though not quite as formidable as the upgraded AMG brakes designed for even greater performance. Ultimately, tire grip, limited by the relatively modest 245mm width, becomes the primary factor in stopping power.
After spending time with the CL600, switching back to a smaller, sportier car like a Golf highlights the distinct character of each vehicle. The CL600 provides a reminder of the unique pleasure of effortless power and luxurious cruising, offering a valuable contrast and appreciation for different driving experiences.
The initial vision for this 2005 Mercedes CL600 included modifications, specifically a custom exhaust system with both quiet mufflers and electric cutouts for unleashing the V12’s full voice. However, after experiencing the car in its stock form, a shift in perspective occurred. The CL600 doesn’t possess the high-pitched, wailing character of an Italian sports car. Instead, its nature is one of quiet, refined power delivery. While unleashing the throttle unleashes immense torque, it does so with a muted intensity, lacking excessive noise or drama. The sensation is one of overwhelming, smooth thrust, moving this substantial vehicle forward with remarkable ease. The 5-speed automatic transmission shifts seamlessly, further contributing to the refined, effortless performance. It became clear that modifying the exhaust would be counter to the car’s inherent character. The decision was made to appreciate the CL600 for precisely what it is: a sophisticated and powerful grand tourer.
Ultimately, the 2005 Mercedes CL600 was always conceived as a temporary indulgence – a means to experience V12 ownership. Like previous automotive diversions, such as a turbo Beetle convertible and a classic Corvair, the CL600 was acquired in good condition to prioritize driving enjoyment over extensive maintenance. However, the anticipated higher maintenance costs associated with a V12, combined with the car’s weight and automatic transmission, did slightly diminish the long-term appeal. After nearly a year of ownership, the V12 bucket list item was checked off. It was, without a doubt, a memorable and powerful experience.
