The A207 E-Class Cabriolet, launched in 2010 and facelifted in 2013, built upon the success of its predecessor, offering a blend of open-air motoring and Mercedes-Benz luxury. The E 220 CDI, introduced with the facelift, provided a diesel-powered option for those prioritizing fuel efficiency and long-distance comfort. Positioned as a mid-range offering, it sat below the more powerful E 350 and E 500 models, and above the entry-level E 200 CDI. The facelift brought revised styling, updated technology, and more efficient engine options, solidifying the E-Class Cabriolet’s position in the premium convertible segment.
Powertrain & Engine Architecture
The heart of the E 220 CDI is the OM 651.911, a 2.1-liter inline-four cylinder diesel engine. This engine is a highly advanced design for its time, featuring common-rail direct injection and a bi-turbocharger setup. The twin turbos – one large, one small – work in sequence to provide both strong low-end torque and high-end power. The smaller turbo spools up quickly at lower RPMs to eliminate turbo lag, while the larger turbo takes over at higher speeds for sustained power delivery. The engine also incorporates an intercooler to further enhance performance by cooling the intake air. The E 220 CDI was typically paired with a 6-speed manual transmission, although a 5-speed automatic transmission was also available, though less common. The automatic transmission offered smooth shifts and convenience, but at the expense of some fuel economy and responsiveness compared to the manual.
Driving Characteristics
The E 220 CDI Cabriolet offered a relaxed and refined driving experience. While not a sports car, the 170 horsepower and 400 Nm (295 lb-ft) of torque provided adequate performance for comfortable cruising and overtaking. Acceleration from 0 to 60 mph took around 8.4 seconds, which was competitive for a diesel-powered convertible of its size. The automatic transmission, while smooth, could feel somewhat sluggish in comparison to the manual version, particularly during quick downshifts. The focus was on providing a comfortable ride, and the suspension effectively absorbed bumps and imperfections in the road. The rear-wheel drive configuration contributed to balanced handling, although it wasn’t particularly engaging for enthusiastic drivers.
Equipment & Trim Levels
The E 220 CDI Cabriolet came standard with a generous array of features, including leather upholstery, automatic climate control, a multi-function steering wheel, and a high-quality audio system. Optional extras included features like the AIRCAP system (which reduces turbulence in the cabin at higher speeds), the AIRSCARF system (which provides warm air around the neck and shoulders), and a premium sound system. Trim levels varied depending on the market, but generally offered upgrades in interior materials, exterior styling, and technology features. The E 220 CDI typically came with a fairly comprehensive standard equipment list, making it a well-appointed vehicle even without opting for numerous extras.
Chassis & Braking
The A207 E-Class Cabriolet utilized a robust chassis designed to provide both rigidity and comfort. The front suspension featured a multi-link setup with coil springs and a transverse stabilizer bar, while the rear suspension employed an independent multi-link spring suspension, also with a stabilizer bar. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, providing enhanced stopping power and control. The suspension tuning was geared towards comfort, prioritizing a smooth ride over sharp handling.
Market Reception & Comparison
The E 220 CDI Cabriolet was generally well-received by critics, who praised its fuel efficiency, comfortable ride, and refined interior. However, some reviewers noted that the performance was not as exhilarating as that of the more powerful E 350 or E 500 models. Compared to the petrol-powered E 350, the E 220 CDI offered significantly better fuel economy, but at the cost of some horsepower and acceleration. The E 220 CDI also provided a more economical alternative to the E 350 d, a more powerful diesel variant. The E-Class Cabriolet competed with other premium convertibles such as the BMW 3 Series Convertible and the Audi A5 Cabriolet.
Legacy
The OM 651 engine family, including the 2.1-liter unit found in the E 220 CDI, has proven to be remarkably durable and reliable. These engines are known for their longevity and relatively low maintenance costs. Today, used examples of the E 220 CDI Cabriolet are readily available and represent a relatively affordable entry point into the world of Mercedes-Benz convertibles. While older examples may require some maintenance, the robust engine and well-built chassis ensure that these cars can provide many years of enjoyable open-air motoring. The E 220 CDI remains a popular choice for those seeking a comfortable, fuel-efficient, and stylish convertible.
