Powertrain & Engine Architecture
The heart of the CL 600 V12 is the M275.953 engine, a 5.5-liter, 60-degree V12. This engine is notable for its twin-turbocharger setup, utilizing one turbocharger per cylinder bank. The turbos are coupled with an intercooler to manage intake air temperatures, maximizing efficiency and power output. Fuel delivery is managed by a multi-port fuel injection system. The engine employs a single overhead camshaft (SOHC) valvetrain, with three valves per cylinder (two intake, one exhaust). The 5G-TRONIC automatic transmission, a five-speed unit, was specifically calibrated to handle the immense torque output of the V12 engine. This transmission features a torque converter and offers smooth, yet decisive shifts.
Driving Characteristics
The CL 600 V12 delivers a driving experience characterized by effortless power and exceptional refinement. The 830 Nm (612 lb-ft) of torque, available from a low 1800 rpm, provides immediate and substantial acceleration in any gear. While the 0-60 mph time of around 4.4 seconds is impressive, the true strength of this powertrain lies in its ability to execute high-speed passes and maintain comfortable cruising speeds with minimal effort. Compared to the CL 63 AMG, which prioritized a more aggressive and sporty feel, the CL 600 V12 emphasized a smoother, more isolated driving experience. The 5G-TRONIC transmission, while not as quick-shifting as more modern gearboxes, contributes to this smoothness. The gear ratios are tuned for relaxed highway cruising, with a focus on maximizing torque delivery rather than outright acceleration.
Equipment & Trim Levels
The CL 600 V12 came standard with a comprehensive array of luxury features. Interior appointments included premium leather upholstery, wood trim, and heated/ventilated front seats with massage functions. Standard technology included Mercedes-Benz’s COMAND infotainment system with navigation, a premium sound system, and a host of driver-assistance features such as Distronic Plus adaptive cruise control, lane-keeping assist, and night vision. Optional extras included a rear seat entertainment system, a panoramic sunroof, and various customization options for interior materials and finishes. The exterior typically featured chrome accents and unique wheel designs to distinguish it from lower trims.
Chassis & Braking
The CL 600 V12 utilized an advanced chassis featuring an ABC (Active Body Control) suspension system. This system employs hydraulic cylinders at each wheel to actively control body roll and pitch, providing a remarkably smooth and stable ride. The suspension was tuned to complement the weight and power of the V12 engine. Braking duties were handled by ventilated disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS) and Electronic Stability Program (ESP). The CL 600 V12 typically featured larger brake rotors and calipers compared to the CL 550, providing enhanced stopping power.
Market Reception & Comparison
The CL 600 V12 was generally well-received by automotive critics, who praised its luxurious interior, powerful engine, and refined driving experience. However, its high price tag and substantial fuel consumption were often noted. Compared to the CL 63 AMG, the CL 600 V12 appealed to a different type of buyer – one who prioritized comfort and effortless power over outright performance. The CL 550, with its smaller V8 engine, offered a more affordable entry point into the CL-Class range, but lacked the sheer presence and performance of the V12 model. Fuel economy was predictably poor, reflecting the engine’s displacement and power output.
Legacy
The M275 V12 engine, while complex, has proven to be relatively reliable when properly maintained. Common issues include occasional turbocharger failures and leaks in the hydraulic lines of the ABC suspension system. However, these issues are typically addressable with specialized maintenance. Today, the CL 600 V12 (C216) represents a unique and desirable grand tourer. Its combination of luxury, power, and exclusivity has made it a sought-after vehicle in the used car market, particularly among collectors and enthusiasts who appreciate its engineering and refinement. Parts availability can be a concern, and maintenance costs are significantly higher than those of more mainstream vehicles, but the CL 600 V12 continues to offer a distinctive and rewarding driving experience.
