2010-2011 Mercedes-Benz E-class Cabrio (A207) E 220 CDI BlueEFFICIENCY (170 Hp) 5G-TRONIC

The Mercedes-Benz E-Class Cabriolet (A207) E 220 CDI BlueEFFICIENCY, produced from March 2010 to April 2011, represented a compelling blend of luxury, fuel efficiency, and open-air motoring within the broader E-Class Cabrio range. Positioned as a mid-range offering, it catered to buyers seeking a refined driving experience without the higher price tag of the more powerful E 350 or E 500 models. This variant combined a turbocharged diesel engine with a five-speed automatic transmission, aiming for a balance between performance and economy. It was part of the A207 generation, which itself was based on the W212 E-Class sedan platform.

Technical Specifications

Powertrain & Engine Architecture

The heart of the E 220 CDI BlueEFFICIENCY was the OM 651.911 2.1-liter inline-four diesel engine. This engine was a highly advanced design for its time, featuring common-rail direct injection and a bi-turbocharger setup. The twin turbos – one large, one small – worked in sequence to minimize turbo lag and provide a broad torque curve. Peak torque of 400 Nm (295 lb-ft) was available from a low 1400 rpm, providing strong pulling power for everyday driving. The engine also incorporated a diesel particulate filter (DPF) to reduce emissions, meeting Euro 5 standards. The 5G-TRONIC automatic transmission, a five-speed unit, was chosen for its smoothness and efficiency. While not as technologically advanced as some newer automatic transmissions, it was well-suited to the engine’s characteristics and provided comfortable shifts.

Driving Characteristics

The E 220 CDI Cabriolet offered a relaxed and refined driving experience. The 170 horsepower engine, while not overtly sporty, provided adequate performance for comfortable cruising and overtaking. Acceleration from 0 to 100 km/h (0-62 mph) took around 8.9 seconds. The automatic transmission contributed to ease of use, particularly in urban environments. Compared to the more powerful E 350 Cabriolet, the E 220 CDI felt less urgent in its acceleration, but it offered significantly better fuel economy. The gear ratios were optimized for fuel efficiency and smooth cruising, rather than outright performance. The rear-wheel-drive configuration provided a balanced feel, although it wasn’t as engaging as some sportier cabriolets.

Equipment & Trim Levels

The E 220 CDI BlueEFFICIENCY Cabriolet came standard with a generous level of equipment, befitting its luxury positioning. Standard features typically included leather upholstery, automatic climate control, a multi-function steering wheel, and a high-quality audio system. Optional extras included features like a wind deflector (to reduce wind noise with the top down), heated seats, a navigation system, and various driver assistance systems. Trim levels were relatively simple, with most customization coming through individual options rather than distinct packages. The interior design followed the elegant and understated aesthetic typical of Mercedes-Benz at the time.

Chassis & Braking

The A207 E-Class Cabriolet utilized a robust chassis designed to provide both comfort and rigidity. The front suspension featured a multi-link setup with a transverse stabilizer, while the rear employed an independent multi-link spring suspension, also with a stabilizer bar. This configuration aimed to deliver a smooth ride and controlled handling. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard. The suspension tuning was geared towards comfort, prioritizing a smooth ride over aggressive handling.

Market Reception & Comparison

The E 220 CDI BlueEFFICIENCY Cabriolet was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined interior. However, some reviewers noted that the engine lacked the outright punch of the more powerful E 350 model. Compared to the E 350, the E 220 CDI offered significantly better fuel economy – around 6.1-6.3 l/100 km (38.6-37.3 US mpg) combined – making it a more economical choice for those who prioritized efficiency. The E 220 CDI also undercut the E 350 in price, making it a more accessible entry point into the E-Class Cabriolet range.

Legacy

The OM 651 engine family, including the 2.1-liter unit found in the E 220 CDI, proved to be remarkably durable and reliable. These engines are known for their longevity and relatively low maintenance costs. In the used car market, the E 220 CDI Cabriolet represents a good value proposition, offering a luxurious and comfortable driving experience at a reasonable price. However, potential buyers should be aware of the maintenance requirements of a diesel engine, including regular DPF servicing. Overall, the E 220 CDI BlueEFFICIENCY Cabriolet remains a well-regarded and capable open-top tourer.
