INTRODUCTION
The A207 E-Class Cabriolet, launched in 2010 and receiving a significant facelift in 2013, represented Mercedes-Benz’s entry into the mid-size luxury convertible market. The E 220 BlueTEC, introduced in 2014, was a key component of the post-facelift range. It aimed to provide a more economical and environmentally friendly option compared to the gasoline-powered variants, without sacrificing the luxury and refinement expected of a Mercedes-Benz. The “BlueTEC” designation signified the implementation of advanced diesel technology, including a particulate filter and selective catalytic reduction (SCR) system utilizing AdBlue, to minimize emissions and meet stringent Euro 6 standards. This model was primarily aimed at European markets where diesel fuel was prevalent and favorable tax incentives were often available for lower-emission vehicles.
Powertrain & Engine Architecture
At the heart of the E 220 BlueTEC Cabriolet lies the OM 651.911, a 2.1-liter inline-four cylinder diesel engine. This engine is a highly refined unit, featuring common-rail direct injection and a sophisticated bi-turbocharger system. The twin turbos, one larger and one smaller, work in tandem to provide both strong low-end torque and sustained power throughout the rev range. The smaller turbocharger spools up quickly at lower engine speeds, eliminating turbo lag and providing immediate responsiveness. As engine speed increases, the larger turbocharger takes over, delivering increased airflow for higher power output. The engine boasts a high compression ratio of 16.2:1, contributing to its thermal efficiency. The 6-speed manual transmission was standard, offering precise shifts and a direct connection to the engine. The transmission’s gear ratios were optimized to balance fuel economy and performance, with a relatively tall sixth gear for efficient cruising.
Driving Characteristics
The E 220 BlueTEC Cabriolet, with its 170 horsepower and 400 Nm (295 lb-ft) of torque, offered a relaxed and refined driving experience. While not overtly sporty, the engine provided ample power for comfortable cruising and overtaking maneuvers. Acceleration from 0 to 60 mph took approximately 8.4 seconds, and the car could reach a top speed of 230 km/h (143 mph). The manual transmission allowed for greater driver engagement, but the gear ratios were spaced to prioritize fuel efficiency over outright acceleration. Compared to the more powerful E 350 Cabriolet, the E 220 BlueTEC felt less urgent in its acceleration, but it compensated with significantly improved fuel economy. The torque curve was broad and flat, making it easy to maintain speed on inclines and during highway passing.
Equipment & Trim Levels
The E 220 BlueTEC Cabriolet came standard with a comprehensive array of features, befitting its luxury positioning. Standard equipment typically included leather upholstery, automatic climate control, a multi-function steering wheel, and a high-quality audio system. The A207 facelift brought updated interior trim and technology, including a revised dashboard layout and the availability of Mercedes-Benz’s COMAND infotainment system with a larger display screen. Optional extras included features such as a wind deflector (to reduce wind buffeting with the top down), heated seats, a premium sound system, and advanced driver-assistance systems like lane keeping assist and blind spot monitoring. Interior color choices were varied, allowing buyers to personalize their vehicle.
Chassis & Braking
The A207 E-Class Cabriolet utilized a robust chassis designed to provide both comfort and handling. The front suspension featured coil springs and an independent multi-link setup with a transverse stabilizer bar, while the rear suspension employed an independent multi-link spring suspension, also with a stabilizer bar. This configuration provided a good balance between ride comfort and body control. The braking system consisted of ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, ensuring safe and controlled stopping power. The steering was a rack-and-pinion system with electric power assistance, providing precise and responsive steering feel.
Market Reception & Comparison
The E 220 BlueTEC Cabriolet was generally well-received by automotive critics, who praised its fuel efficiency, refined engine, and comfortable ride. It was seen as a sensible alternative to the more expensive and less economical gasoline-powered models. Compared to the E 250 CDI (a slightly more powerful diesel variant), the E 220 BlueTEC offered a lower price point, making it more accessible to a wider range of buyers. However, some critics noted that the 170 horsepower engine could feel slightly underpowered when the car was fully loaded or driving uphill. Fuel economy was a major selling point, with the E 220 BlueTEC achieving combined fuel consumption figures of around 4.9-5.1 l/100 km (48-46.1 US mpg).
Legacy
The OM 651 engine family, including the 2.1-liter unit found in the E 220 BlueTEC, has proven to be remarkably durable and reliable. These engines are known for their longevity and relatively low maintenance costs. On the used car market, the E 220 BlueTEC Cabriolet represents a good value proposition for buyers seeking a luxurious and fuel-efficient convertible. However, potential buyers should be aware of the maintenance requirements associated with diesel engines, including regular servicing of the diesel particulate filter (DPF) and the AdBlue system. Overall, the E 220 BlueTEC Cabriolet remains a desirable and well-regarded vehicle, offering a compelling combination of style, comfort, and economy.
