Powertrain & Engine Architecture
The heart of the CLC 350 is the M272.960 3.5-liter naturally aspirated V6 engine. This engine, a staple in many Mercedes-Benz models of the era, is known for its smooth power delivery and relatively robust construction. The M272 features a three-valve per cylinder design (two intake, one exhaust) and utilizes a multi-port fuel injection system. The engine’s block is constructed from aluminum, contributing to weight savings. The 350 variant produced 272 horsepower and 350 Nm (258 lb-ft) of torque, peaking at 2400-5000 rpm. The engine is longitudinally mounted in the front of the vehicle, driving the rear wheels. The standard transmission for the CLC 350 was a 6-speed manual gearbox, although a 7G-TRONIC automatic transmission was also available as an option. The 7G-TRONIC offered smoother shifts and enhanced fuel efficiency, but at the expense of some driver engagement.
Driving Characteristics
The CLC 350 offered a noticeably more engaging driving experience than the lower-powered variants. The 3.5-liter V6 provided ample power for spirited driving, with a 0-60 mph time of around 6 seconds. The rear-wheel-drive configuration contributed to a balanced chassis and predictable handling. The 6-speed manual transmission allowed for precise gear selection, while the optional 7G-TRONIC automatic provided seamless shifts. Compared to the 1.8L Kompressor models, the CLC 350 offered significantly more torque throughout the rev range, making it more effortless in everyday driving situations. While not a dedicated sports car, the CLC 350 provided a satisfying blend of performance and comfort.
Equipment & Trim Levels
The CLC 350 typically came well-equipped, reflecting its position as the range-topping model. Standard features included leather upholstery, automatic climate control, a multi-function steering wheel, and a premium audio system. Optional extras included a panoramic sunroof, bi-xenon headlights, and a navigation system. The interior design was generally functional and well-built, although it lacked some of the more luxurious touches found in higher-end Mercedes-Benz models. The dashboard layout was relatively straightforward, with easy-to-use controls. Exterior styling cues included unique alloy wheel designs and subtle body kit enhancements.
Chassis & Braking
The CLC 350 utilized a MacPherson strut front suspension and a multi-link rear suspension. This setup provided a good balance between ride comfort and handling precision. The CLC 350 featured ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock braking system (ABS) was standard. The suspension was tuned to provide a slightly firmer ride than the base models, enhancing handling responsiveness. The steering was precise and well-weighted, providing good feedback to the driver.
Market Reception & Comparison
The CLC 350 received generally positive reviews from automotive critics. It was praised for its powerful engine, engaging handling, and stylish design. However, some critics noted that the interior felt somewhat cramped compared to other coupes in its class. Compared to the CLC 180 Kompressor or 200 Kompressor, the CLC 350 offered a substantial performance upgrade, but at a higher price point. Fuel economy was also lower with the larger engine. The CLC 350 competed with other compact coupes such as the BMW 1 Series Coupe and the Audi TT.
Legacy
The M272 engine, found in the CLC 350, is generally considered to be a reliable powerplant when properly maintained. Common issues include oil leaks and occasional problems with the balance shaft. The CLC 350 has become a sought-after model in the used car market, particularly among enthusiasts who appreciate its combination of performance and style. While not as iconic as some other Mercedes-Benz models, the CLC 350 represents a compelling option for those seeking a sporty and affordable coupe. Its rear-wheel-drive layout and powerful V6 engine continue to appeal to driving enthusiasts today.
