The Mercedes-Benz CLA 220 CDI, produced from 2013 to 2014, represented a key entry point into the C117 CLA Coupe range. Positioned as a diesel-powered variant, it aimed to deliver a blend of style, efficiency, and practicality within the compact executive class. This model was particularly significant in European markets where diesel engines held a substantial share of the automotive landscape. The CLA 220 CDI utilized a 2.1-liter turbocharged diesel engine paired with Mercedes-Benz’s 7G-DCT dual-clutch transmission, offering a balance between performance and fuel economy. It served as a more economical alternative to the gasoline-powered CLA 250, while providing more power than the base CLA 200 models.

Powertrain & Engine Architecture
The heart of the CLA 220 CDI is the OM651 DE 22 LA, a 2.1-liter inline-four cylinder diesel engine. This engine is a member of the OM651 family, known for its robust construction and efficiency. It features a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A turbocharger with an intercooler further enhances performance by forcing more air into the cylinders. The engine produces 170 horsepower at 3400-4000 rpm and a substantial 350 Nm (258 lb-ft) of torque between 1400-3400 rpm. This broad torque curve is a hallmark of diesel engines, providing strong pulling power at lower engine speeds. The 7G-DCT (7-speed Dual Clutch Transmission) is a crucial component, offering quick and smooth gear changes. This transmission contributes to both fuel efficiency and a more engaging driving experience compared to a traditional automatic.
Driving Characteristics
The CLA 220 CDI with the 7G-DCT delivers a comfortable and refined driving experience. While not a sports car, the engine’s torque provides ample acceleration for everyday driving and highway merging. The 0-60 mph time of around 7.8 seconds is respectable for a diesel-powered coupe. The 7G-DCT transmission shifts quickly and efficiently, minimizing power loss between gears. Compared to the CLA 250 with its gasoline engine, the 220 CDI offers better fuel economy but less outright performance. The manual transmission options available on other CLA models provided a more direct connection to the engine, but the 7G-DCT offered convenience and ease of use. The gear ratios are tuned for efficiency, prioritizing fuel economy over aggressive acceleration.
Equipment & Trim Levels
The CLA 220 CDI typically came equipped with a reasonable level of standard features. These included automatic climate control, a multi-function steering wheel, and a basic infotainment system with a central display screen. Interior upholstery was generally cloth, with leather options available as upgrades. Common optional extras included a panoramic sunroof, upgraded sound system, navigation system, and various driver assistance features like parking sensors and lane keeping assist. Trim levels varied slightly depending on the market, but generally followed a progression from base models to more luxurious “Sport” or “AMG Line” packages, which added cosmetic enhancements and additional features.
Chassis & Braking
The CLA 220 CDI utilizes an independent multi-link suspension at both the front and rear axles. This suspension setup provides a good balance between ride comfort and handling. The front brakes are ventilated discs, while the rear brakes are solid discs. ABS (Anti-lock Braking System) is standard, ensuring safe and controlled braking in various conditions. The electric power steering provides a light and precise steering feel. The chassis is tuned to prioritize comfort and stability, rather than outright sportiness. Stabilizer bars are fitted to both axles to reduce body roll during cornering.
Market Reception & Comparison
The CLA 220 CDI was generally well-received by automotive critics, particularly for its fuel efficiency and comfortable ride. It was seen as a practical and stylish option for buyers seeking a compact executive car with low running costs. Compared to the CLA 250, the 220 CDI offered significantly better fuel economy, making it a more attractive option for those who covered long distances. However, the 250 provided more exhilarating performance. The 220 CDI also compared favorably to other diesel-powered competitors in the segment, such as the Audi A3 TDI and the BMW 2 Series Active Tourer diesel, offering a competitive blend of features and price.
Legacy
The OM651 engine family, including the version used in the CLA 220 CDI, has proven to be remarkably durable and reliable. With proper maintenance, these engines can easily exceed 200,000 miles. The 7G-DCT transmission is also generally reliable, although some owners have reported issues with the mechatronic unit. On the used car market, the CLA 220 CDI remains a popular choice for buyers seeking a fuel-efficient and stylish coupe. Its relatively low running costs and proven reliability make it a sensible option, although potential buyers should be aware of the potential for diesel particulate filter (DPF) issues, particularly if the car has primarily been used for short journeys.
