The Mercedes-Benz CLK 280, produced from July 2005 to August 2009 as part of the A209 facelift generation, represented a compelling blend of performance and luxury within the CLK range. Available exclusively as a two-door cabriolet, it occupied a mid-range position in the lineup, offering a step up in power and refinement from the CLK 200 and 230 Kompressor models, while remaining more accessible than the flagship CLK 350 and high-performance CLK 63 AMG. The A209 facelift brought revised styling, improved interior materials, and updated technology compared to the pre-facelift W209 models, solidifying the CLK’s position as a desirable open-top grand tourer.

Powertrain & Engine Architecture
The CLK 280 was powered by the M272.940 3.0-liter naturally aspirated V6 engine. This engine, a cornerstone of Mercedes-Benz’s mid-size offerings during the 2000s, featured a magnesium block and aluminum cylinder heads, contributing to a relatively lightweight construction. It employed a three-valve-per-cylinder design (two intake, one exhaust) and a double overhead camshaft (DOHC) valvetrain. Fuel delivery was handled by a multi-port fuel injection system, providing precise fuel metering for optimal combustion. The engine produced 231 horsepower at 6,000 rpm and 300 Nm (221 lb-ft) of torque between 2,500 and 5,000 rpm. The six-speed manual transmission was standard, offering precise gear changes and a more engaging driving experience.
Driving Characteristics
The CLK 280 with the manual transmission provided a balanced driving experience. While not overtly sporty, the engine delivered sufficient power for comfortable cruising and spirited driving. The 0-60 mph sprint took approximately 7.3 seconds, and the car could reach a top speed of 155 mph. The manual gearbox allowed for greater control over the engine’s powerband, making it more engaging than the optional automatic transmission. The gear ratios were well-chosen for both highway and city driving, providing adequate acceleration in most situations. Compared to the more powerful CLK 350, the 280 offered a slightly more relaxed driving experience, prioritizing comfort and refinement over outright performance.
Equipment & Trim Levels
The CLK 280 came standard with a generous array of features, including leather upholstery, automatic climate control, power-adjustable seats, and a premium audio system. Optional extras included a panoramic sunroof, bi-xenon headlights, and a COMAND infotainment system with navigation. Interior trim options typically included wood or aluminum accents. The cabriolet featured a fully automatic retractable hardtop, providing open-air driving enjoyment with the security and refinement of a coupe when closed.
Chassis & Braking
The CLK 280 utilized an independent suspension system at all four wheels. The front suspension employed McPherson struts with a transverse stabilizer bar, while the rear featured a multi-link setup, also with a stabilizer bar. This configuration provided a comfortable ride and good handling characteristics. Braking duties were handled by ventilated discs at the front and solid discs at the rear, equipped with ABS (Anti-lock Braking System) for enhanced safety. The steering was a rack-and-pinion system with hydraulic power assistance, offering precise and responsive steering feel.
Market Reception & Comparison
The CLK 280 was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and refined driving experience. The manual transmission was appreciated by enthusiasts, offering a more engaging driving experience than the automatic. Fuel economy was reasonable for a V6-powered cabriolet, averaging around 24.8 mpg in combined driving. Compared to the CLK 350, the 280 offered a more affordable entry point into the CLK range, while still providing a luxurious and enjoyable driving experience. The 280 was often seen as a sweet spot in the lineup, balancing performance, comfort, and value.
Legacy
The M272 engine family, including the 280 variant, has proven to be relatively reliable over the long term, provided regular maintenance is performed. Common issues include oil leaks and occasional problems with the balance shaft. The CLK 280, particularly the manual transmission models, have become increasingly sought after by enthusiasts in the used car market. Its combination of classic Mercedes-Benz styling, comfortable interior, and engaging driving experience makes it a desirable alternative to more modern convertibles. While parts availability is generally good, specialized components may require sourcing from Mercedes-Benz dealerships or specialist parts suppliers.
