INTRODUCTION
The A238 E-Class Cabriolet, launched in 2017, represented the fifth generation of Mercedes-Benz’s popular open-top offering. Built on the W213 E-Class sedan platform, the Cabriolet aimed to deliver a luxurious and refined experience with the added enjoyment of open-air motoring. The E 220d 9G-TRONIC variant, powered by a 2.0-liter turbocharged diesel engine, was a key model in the lineup, offering a balance between performance, fuel efficiency, and affordability. It appealed to buyers seeking a comfortable and stylish convertible without the higher price tag of the more potent gasoline options.
Powertrain & Engine Architecture
The heart of the E 220d Cabriolet is the OM 654.920, a 1950cc inline-four cylinder diesel engine. This engine is a member of Mercedes-Benz’s modular engine family, known for its lightweight construction and advanced technology. It features a high-pressure common rail direct injection system, delivering fuel at up to 2,500 bar for optimized combustion. The engine also incorporates a variable geometry turbocharger with an intercooler, enhancing both power and efficiency. The 9G-TRONIC nine-speed automatic transmission is a crucial component, offering smooth and efficient gear changes. This transmission is designed to maximize fuel economy and provide a comfortable driving experience. It features a wide gear ratio spread, allowing the engine to operate in its most efficient range more often.
Driving Characteristics
The E 220d Cabriolet, with its 194 horsepower and 400 Nm (295 lb-ft) of torque, provides adequate performance for comfortable cruising and everyday driving. Acceleration from 0 to 60 mph takes approximately 7.3 seconds, and it reaches a top speed of 237 km/h (147 mph). While not as quick as the E 300 or E 400 models, the E 220d offers a more relaxed and fuel-efficient driving experience. The 9G-TRONIC transmission contributes to this, providing seamless gear changes and keeping the engine in its optimal power band. The gear ratios are tuned for efficiency, prioritizing smooth acceleration over outright speed. Compared to manual transmission versions (which were not widely available in this configuration), the automatic offers greater convenience and ease of use, particularly in city traffic.
Equipment & Trim Levels
The E 220d Cabriolet typically came well-equipped as standard. Features included automatic climate control, leather upholstery, power-adjustable seats, a premium sound system, and a suite of safety features like ABS, ESP, and multiple airbags. The Cabriolet also featured a fully automatic fabric soft top, which could be raised or lowered in around 20 seconds at speeds up to 60 km/h. Optional extras included features like the AIRMATIC air suspension, which provided a more comfortable ride, a head-up display, and advanced driver-assistance systems like lane keeping assist and adaptive cruise control. Interior trim options varied, with choices in wood, aluminum, and carbon fiber finishes.
Chassis & Braking
The A238 E-Class Cabriolet utilizes a sophisticated chassis design, featuring an independent multi-link suspension at both the front and rear. This setup provides a comfortable ride and good handling characteristics. The E 220d, being the entry-level model, typically came with disc brakes at the front and ventilated discs at the rear. The braking system is enhanced by ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) for improved safety. Stabilizer bars are fitted front and rear to reduce body roll during cornering. The suspension tuning is geared towards comfort, prioritizing a smooth ride over sporty handling, although the optional AIRMATIC suspension could significantly enhance both ride quality and handling.
Market Reception & Comparison
The E 220d Cabriolet was generally well-received by automotive critics. It was praised for its comfortable ride, refined interior, and fuel efficiency. However, some reviewers noted that the engine lacked the outright performance of the more powerful gasoline variants. Compared to the E 300, the E 220d offered a more affordable entry point into the E-Class Cabriolet range, but at the expense of some performance. In terms of fuel economy, the E 220d significantly outperformed the gasoline models, making it an attractive option for drivers who prioritize efficiency. Reliability has been generally good, with the OM 654 engine proving to be a robust and dependable unit.
Legacy
The Mercedes-Benz E-Class Cabriolet (A238) E 220d 9G-TRONIC has established itself as a popular choice in the used car market. Its combination of luxury, comfort, and fuel efficiency continues to appeal to buyers seeking a stylish and practical convertible. The OM 654 diesel engine is known for its longevity and relatively low maintenance costs, making it a desirable powertrain. While newer models offer more advanced technology and features, the A238 E 220d remains a compelling option for those seeking a well-built and refined open-top experience.
