INTRODUCTION
The Mercedes-Benz CL 500 V8 (388 Hp) 4MATIC, part of the C216 series produced from 2008 to 2010, was a flagship grand tourer designed to offer a luxurious and powerful driving experience. Built on the sophisticated platform shared with the S-Class (W221), the CL-Class aimed for a more dynamic and sporty character. The CL 500 4MATIC, specifically, combined a naturally aspirated 5.5-liter V8 engine with Mercedes’ 4MATIC all-wheel-drive system and the 7G-TRONIC seven-speed automatic transmission. This configuration positioned it as a versatile option, appealing to buyers in regions with inclement weather or those prioritizing confident handling.
Powertrain & Engine Architecture
At the heart of the CL 500 4MATIC lies the M273.968 5.5-liter naturally aspirated V8 engine. This engine, a hallmark of Mercedes-Benz engineering during the period, features a three-valve-per-cylinder design (two intake, one exhaust) and utilizes multi-port fuel injection. The engine produces 388 horsepower at 6000 rpm and 530 Nm (390.91 lb-ft) of torque between 2800 and 4800 rpm. The 7G-TRONIC automatic transmission, known for its smooth and responsive shifts, features seven forward gears and a torque converter lock-up clutch for improved efficiency. The 4MATIC system employs a full-time all-wheel-drive setup, distributing power between the front and rear axles for enhanced traction and stability. The system is primarily rear-biased, providing a sporty feel while maintaining all-weather capability.
Driving Characteristics
The CL 500 4MATIC delivers a refined and powerful driving experience. While not as overtly sporty as some competitors, the combination of the V8 engine and the 7G-TRONIC transmission provides ample acceleration – 0 to 60 mph in approximately 5.1 seconds. The 4MATIC system contributes to excellent grip and stability, particularly in challenging road conditions. The air suspension system, standard on this model, further enhances ride comfort, absorbing bumps and providing a smooth, controlled experience. Compared to the CL 600 with its twin-turbo V12, the CL 500 offers a slightly less dramatic but more accessible power delivery. The 7G-TRONIC transmission is well-tuned for both relaxed cruising and more spirited driving, offering manual shift capability for greater driver control.
Equipment & Trim Levels
The CL 500 4MATIC came generously equipped as standard. Key features included leather upholstery, power-adjustable and heated front seats with memory function, a premium audio system, automatic climate control, and a sunroof. The interior boasted high-quality materials and meticulous craftsmanship. Optional extras included features like massaging seats, a rear-seat entertainment system, a panoramic sunroof, and advanced driver-assistance systems such as Distronic Plus adaptive cruise control and lane-keeping assist. Trim levels were relatively limited, with most customization occurring through the selection of optional packages and individual options.
Chassis & Braking
The C216 CL-Class features a sophisticated chassis design with an independent multi-link suspension at both the front and rear. The air suspension system, as mentioned previously, provides adjustable ride height and damping characteristics. The braking system consists of ventilated discs on all four wheels, coupled with ABS (Anti-lock Braking System) and Electronic Stability Program (ESP) for enhanced safety. The steering is a hydraulic power-assisted rack-and-pinion system, offering precise and responsive control.
Market Reception & Comparison
The CL 500 4MATIC was generally well-received by automotive critics. It was praised for its luxurious interior, comfortable ride, and powerful engine. The 4MATIC system was seen as a significant advantage in regions with harsh winters or unpredictable weather. Compared to other grand tourers of the time, such as the BMW 6 Series and the Aston Martin DB9, the CL 500 4MATIC offered a unique blend of luxury, performance, and all-weather capability. Fuel economy, however, was a common criticism, with the V8 engine consuming a considerable amount of fuel, especially in urban driving. Reliability was generally good, although the complex electronic systems could occasionally require attention.
Legacy
The Mercedes-Benz CL 500 V8 (388 Hp) 4MATIC remains a desirable grand tourer in the used car market. Its combination of luxury, performance, and all-wheel-drive capability continues to appeal to buyers seeking a sophisticated and capable vehicle. The M273 engine, while not the most fuel-efficient, is known for its durability and relatively straightforward maintenance. However, potential buyers should be aware of the cost of maintaining the complex electronic systems and air suspension. Overall, the CL 500 4MATIC represents a high point in Mercedes-Benz grand touring design and engineering, offering a refined and rewarding driving experience that still holds up well today.
