2013-2014 Mercedes-Benz E-class Cabrio (A207 facelift ) E 250 CDI (204 Hp)

The Mercedes-Benz E-Class Cabriolet (A207) facelift, specifically the E 250 CDI variant produced from June 2013 to July 2014, represented a compelling blend of diesel efficiency and open-air luxury within the mid-size premium convertible segment. Positioned as a mid-range offering within the A207 facelift range, it slotted below the more powerful E 350 and E 550 models, and above the base E 220 CDI. This variant aimed to appeal to buyers seeking a refined driving experience with lower running costs, particularly in European markets where diesel fuel was prevalent and taxation favored lower emissions. The A207 generation, built on the W207 platform, offered a significant update to the original A207 released in 2009, with revised styling, updated technology, and improved efficiency.

Technical Specifications

Powertrain & Engine Architecture

The E 250 CDI Cabriolet was powered by the OM651.911 2.1-liter inline-four cylinder diesel engine. This engine was a mainstay of the Mercedes-Benz lineup, known for its robust construction and fuel efficiency. The OM651 featured a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A sophisticated bi-turbocharger setup, utilizing a small, low-inertia turbocharger for quick response and a larger turbocharger for peak power, contributed to the engine’s 500 Nm (368.78 lb-ft) of torque available from a low 1600-1800 rpm. The engine also incorporated an intercooler to further enhance performance. The engine’s double overhead camshaft (DOHC) valvetrain, with four valves per cylinder, maximized breathing efficiency. The A207 E 250 CDI utilized a 6-speed manual transmission as standard, delivering power to the rear wheels. While an automatic transmission was available as an option, the manual gearbox was favored by drivers prioritizing fuel economy and a more engaging driving experience.

Driving Characteristics

The E 250 CDI Cabriolet offered a comfortable and refined driving experience, prioritizing fuel efficiency and relaxed cruising over outright performance. The 204 horsepower and 500 Nm of torque provided adequate acceleration, with a 0-60 mph time of around 7.4 seconds. However, it wasn’t a particularly sporty vehicle. The manual transmission, while precise, required frequent shifting to maintain momentum, especially when overtaking. Compared to the E 350 or E 550 Cabriolets, the E 250 CDI felt noticeably less powerful, particularly at higher speeds. The focus was on providing a smooth and quiet ride, making it well-suited for long-distance journeys. The relatively low weight of the diesel engine compared to the gasoline alternatives contributed to balanced handling, although it wasn’t a corner carver.

Equipment & Trim Levels

The E 250 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. The A207 facelift introduced a revised dashboard design with a more modern aesthetic. Optional extras included features like the AIRCAP system (reducing turbulence in the cabin at higher speeds), COMAND infotainment system with navigation, heated seats, and a premium sound system. Trim levels were relatively simple, with most customization options available as individual selections rather than pre-defined packages. The standard interior color schemes were typically conservative, with black, grey, and beige options being the most common.

Chassis & Braking

The A207 Cabriolet featured a robust chassis designed to provide a comfortable ride and good handling. The front suspension utilized 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 minimized body roll and provided a stable platform. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing adequate stopping power. Anti-lock braking system (ABS) was standard, enhancing safety and control. The steering was a rack-and-pinion system with electric power assistance, offering a light and precise feel.

Market Reception & Comparison

The E 250 CDI Cabriolet was generally well-received by automotive critics, who praised its fuel efficiency, comfortable ride, and refined interior. However, some reviewers noted its lack of outright performance compared to its more powerful siblings. Compared to the E 220 CDI, the E 250 CDI offered a noticeable power upgrade, making it a more enjoyable driving experience. Against competitors like the BMW 3 Series Convertible and Audi A5 Cabriolet, the E 250 CDI offered a more luxurious and comfortable experience, but often at a higher price point. Its fuel economy was competitive within its class, making it an attractive option for buyers prioritizing running costs.

Legacy

The OM651 engine, found in the E 250 CDI, has proven to be remarkably durable and reliable. With proper maintenance, these engines can easily exceed 200,000 miles. The A207 E-Class Cabriolet, including the E 250 CDI variant, has maintained a relatively strong presence in the used car market, appealing to buyers seeking a stylish and comfortable convertible with reasonable running costs. Common issues are typically related to wear and tear on suspension components and electrical systems, but the engine itself is generally considered to be very robust. The E 250 CDI represents a sweet spot in the A207 range, offering a good balance of performance, efficiency, and luxury.
