INTRODUCTION
The CLS 500 (C219 facelift) was produced between 2008 and 2009, building upon the original CLS’s groundbreaking four-door coupe design. The facelift brought revised styling, improved interior appointments, and updated technology. It was built on the Mercedes-Benz 1HX0/A3 platform, shared with the W211 E-Class and S211 E-Class wagon. The CLS 500 aimed to provide a more luxurious and performance-oriented alternative to traditional sedans, appealing to buyers who desired a distinctive and sophisticated vehicle.
Powertrain & Engine Architecture
At the heart of the CLS 500 lies the M273.960 5.5-liter naturally aspirated V8 engine. This engine, a cornerstone of Mercedes-Benz’s performance lineup during this period, produces 388 horsepower at 6000 rpm and 530 Nm (390.91 lb.-ft.) of torque between 2800 and 4800 rpm. The engine features a three-valve per cylinder design (two intake, one exhaust) and utilizes multi-port fuel injection. The M273 engine is known for its smooth power delivery and robust construction. It’s paired with Mercedes-Benz’s 7G-TRONIC seven-speed automatic transmission, which offered smooth and responsive shifts. This transmission was a significant advancement over previous iterations, contributing to both performance and fuel efficiency. The 7G-TRONIC featured a torque converter lock-up clutch that engaged in multiple gears, reducing slippage and improving fuel economy.
Driving Characteristics
The CLS 500’s 5.5-liter V8 and 7G-TRONIC transmission delivered a refined and powerful driving experience. Acceleration from 0 to 60 mph was achieved in approximately 5.1 seconds, and the car was electronically limited to a top speed of 155 mph. The 7G-TRONIC transmission provided quick and seamless gear changes, enhancing the car’s responsiveness. Compared to the CLS 350, the 500 offered a substantial increase in power and torque, resulting in noticeably quicker acceleration and more effortless cruising. While not as overtly sporty as some competitors, the CLS 500 provided a comfortable and confident ride, thanks to its air suspension and well-tuned chassis. The gear ratios were optimized for both acceleration and highway cruising, providing ample power in most situations.
Equipment & Trim Levels
The CLS 500 came standard with a comprehensive list of features, befitting its position as a luxury vehicle. Standard equipment included leather upholstery, wood trim, dual-zone automatic climate control, a premium sound system, and a power sunroof. Optional extras included a navigation system, rear-seat entertainment, massaging seats, and a variety of exterior customization options. The interior design emphasized luxury and comfort, with high-quality materials and meticulous attention to detail. The CLS 500’s trim levels were relatively limited, with most customization occurring through optional packages.
Chassis & Braking
The CLS 500 featured an independent multi-link suspension at all four corners, complemented by an air suspension system that provided a smooth and controlled ride. The air suspension allowed the driver to adjust the ride height and stiffness, adapting to different driving conditions. Braking duties were handled by ventilated discs on all four wheels, providing ample stopping power. The CLS 500 also incorporated ABS (Anti-lock Braking System) and electronic stability control to enhance safety. The suspension was tuned to balance comfort and handling, providing a stable and predictable driving experience.
Market Reception & Comparison
The CLS 500 was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and distinctive styling. However, some reviewers noted its relatively high fuel consumption and its price point. Compared to the CLS 350, the 500 offered a significant performance upgrade but came at a higher cost. The CLS 500 competed with other luxury four-door coupes, such as the Porsche Panamera and the Audi A7, offering a unique blend of style, performance, and comfort. Fuel economy was a common criticism, with combined figures around 20 mpg being typical.
Legacy
The M273 engine, found in the CLS 500, is generally considered a reliable powerplant when properly maintained. Common issues include occasional oil leaks and potential problems with the thermostat housing. The 7G-TRONIC transmission is also generally reliable, but regular fluid changes are crucial for longevity. Today, the CLS 500 (C219) represents a desirable entry point into the world of high-performance Mercedes-Benz coupes. Well-maintained examples command reasonable prices in the used car market, appealing to enthusiasts who appreciate its unique styling and powerful V8 engine. Its blend of luxury, performance, and distinctive design continues to make it a sought-after vehicle among collectors and enthusiasts alike.
