The Mercedes-Benz E-Class Cabriolet (A207) facelift, produced from June 2013 to July 2014, represented a significant refinement of the second-generation E-Class convertible. The E 350 V6 variant, equipped with the 7G-TRONIC PLUS automatic transmission, occupied a sweet spot in the lineup, offering a blend of performance, luxury, and relative affordability compared to the range-topping E 550. Positioned as a mid-range offering, it catered to buyers seeking a sophisticated open-air experience without the higher price tag of the more powerful models. This generation of E-Class Cabriolet was built on the W207 platform, sharing its underpinnings with the E-Class Coupe.

Powertrain & Engine Architecture
The heart of the E 350 Cabriolet was the M276.952 3.5-liter naturally aspirated V6 engine. This engine, a cornerstone of Mercedes-Benz’s mid-range offerings during this period, featured direct fuel injection and a double overhead camshaft (DOHC) valvetrain. Its 60-degree V-configuration contributed to a smooth and balanced operation. The engine produced 306 horsepower at 6500 rpm and 273 lb-ft of torque between 3500 and 5250 rpm. The 7G-TRONIC PLUS automatic transmission, a seven-speed unit, was specifically tuned to complement the V6’s power delivery. This transmission offered smooth shifts and a wide range of gear ratios, enhancing both acceleration and fuel efficiency. The transmission also included a manual shift mode for more driver involvement.
Driving Characteristics
The E 350 Cabriolet with the 7G-TRONIC PLUS offered a refined and comfortable driving experience. While not as overtly sporty as some of its competitors, it provided ample power for both highway cruising and spirited driving. The automatic transmission, while smooth, could feel slightly hesitant at times, particularly during quick downshifts. Compared to the six-speed manual transmission available on other E-Class models, the 7G-TRONIC PLUS prioritized comfort and ease of use over outright performance. The gear ratios were optimized for fuel economy and relaxed cruising, making it an ideal grand tourer. Acceleration from 0 to 60 mph took approximately 6.1 seconds, a respectable figure for a luxury convertible of its size.
Equipment & Trim Levels
The E 350 Cabriolet came standard with a generous array of features, including leather upholstery, automatic climate control, a premium sound system, and a power-operated soft top. Optional extras included features like the AIRMATIC air suspension, which provided a more comfortable ride, and the COMAND infotainment system with navigation. Interior trim options ranged from wood veneers to aluminum accents, allowing buyers to personalize the cabin to their tastes. The standard seats offered excellent support and comfort, and were available in a variety of colors. The facelifted A207 models also benefited from updated interior styling and improved infotainment options.
Chassis & Braking
The E 350 Cabriolet featured a sophisticated suspension system designed to balance comfort and handling. The front suspension utilized coil springs and an independent multi-link setup, while the rear suspension employed an independent multi-link spring suspension with a stabilizer bar. This configuration minimized body roll and provided a stable and controlled ride. Braking duties were handled by ventilated discs on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) was standard, enhancing safety and control during emergency braking situations. The steering was a rack-and-pinion system with power assistance, offering precise and responsive handling.
Market Reception & Comparison
The E 350 Cabriolet was generally well-received by automotive critics, who praised its luxurious interior, comfortable ride, and refined powertrain. However, some reviewers noted that the handling wasn’t as sharp as some of its rivals, such as the BMW 4 Series Convertible. Compared to the E 550 Cabriolet, the E 350 offered a more affordable entry point into the E-Class convertible range, while still providing a satisfying level of performance and luxury. Fuel economy was respectable for a vehicle of its size and class, averaging around 32.7 mpg in combined driving. Reliability was generally good, although some owners reported minor issues with the infotainment system and the power-operated soft top.
Legacy
The A207 E-Class Cabriolet, particularly the E 350 variant, has proven to be a relatively reliable and durable vehicle. The M276 engine is known for its longevity, and the 7G-TRONIC PLUS transmission is generally considered to be robust. On the used car market, these models represent a good value for buyers seeking a luxurious and well-equipped convertible. Maintenance costs are reasonable, although preventative maintenance, such as regular fluid changes and inspections, is essential to ensure long-term reliability. The E 350 Cabriolet remains a popular choice among enthusiasts who appreciate its blend of style, comfort, and performance.
