INTRODUCTION
The Mercedes-Benz E 400 Cabriolet (A207, facelift) debuted in June 2013 as part of the refreshed A207 E-Class range. Building upon the foundation of the A207 platform – shared with the Coupe – the Cabriolet offered open-top motoring with the renowned Mercedes-Benz luxury and build quality. The facelift brought a more contemporary aesthetic, with revised front and rear styling, updated interior appointments, and crucially, a new generation of more efficient and powerful engines. The E 400, with its 3.0-liter V6, served as the performance flagship of the non-AMG Cabriolet lineup for a relatively short period, being replaced by newer models in 2014.
Powertrain & Engine Architecture
At the heart of the E 400 Cabriolet lies the M276.820 3.0-liter V6 engine. This engine is a key example of Mercedes-Benz’s advancements in direct injection and forced induction technology. It features twin turbochargers, one for each bank of cylinders, providing a broad torque curve and responsive power delivery. The engine utilizes a third-generation direct injection system, injecting fuel directly into the combustion chamber at pressures up to 200 bar for improved efficiency and reduced emissions. The valvetrain employs Dual Overhead Camshafts (DOHC) with four valves per cylinder. Paired with the engine is the 7G-TRONIC PLUS seven-speed automatic transmission, known for its smooth and quick shifts. This transmission features a torque converter lock-up clutch for improved fuel economy at cruising speeds. The 7G-TRONIC PLUS also incorporates adaptive shift programs that adjust to the driver’s style and road conditions.
Driving Characteristics
The E 400 Cabriolet delivers a refined and engaging driving experience. The 333 horsepower and 354 lb-ft of torque provide brisk acceleration, with a 0-60 mph time of around 5 seconds. The 7G-TRONIC PLUS transmission is well-matched to the engine, offering seamless gear changes and contributing to a relaxed cruising experience. While not as overtly sporty as the E 550 Cabriolet or the AMG variants, the E 400 provides ample power for confident overtaking and enjoyable spirited driving. The gear ratios are tuned for a balance between acceleration and fuel efficiency. Compared to the E 350 Cabriolet, the E 400 offers a noticeable increase in performance, particularly in mid-range acceleration. The added power makes it more capable on long highway journeys and when carrying passengers.
Equipment & Trim Levels
The E 400 Cabriolet came standard with a generous array of features, reflecting its premium positioning. Standard equipment typically included leather upholstery, power-adjustable front seats with memory function, dual-zone automatic climate control, a premium sound system, and a power-retractable soft top. Optional extras included features such as the AIRMATIC air suspension system, which provided a more comfortable ride, a panoramic sunroof, and advanced driver-assistance systems like Distronic Plus adaptive cruise control and lane-keeping assist. Interior trim options included various wood veneers and aluminum accents. The standard dashboard configuration featured a high-resolution infotainment screen integrated into the center console.
Chassis & Braking
The A207 E-Class Cabriolet utilized a robust chassis designed to provide both comfort and handling. The front suspension featured a multi-link independent setup with coil springs and a transverse stabilizer bar. The rear suspension also employed a multi-link independent design with coil springs and a stabilizer bar. Braking duties were handled by ventilated discs on all four wheels, providing ample stopping power. The E 400 typically came equipped with larger brake rotors compared to the base models. Anti-lock Braking System (ABS) and Electronic Stability Program (ESP) were standard safety features.
Market Reception & Comparison
The E 400 Cabriolet was generally well-received by automotive critics. Reviewers praised its powerful engine, refined ride quality, and luxurious interior. The combination of performance and comfort made it a compelling alternative to other luxury convertibles in its class. Compared to the E 350 Cabriolet, the E 400 offered a significant performance upgrade, but at a higher price point. Fuel economy was respectable for a vehicle of its size and performance, averaging around 30 mpg combined. Reliability was generally good, although some owners reported minor issues with the electronic systems.
Legacy
The Mercedes-Benz E 400 Cabriolet (A207, facelift) remains a desirable used car today, particularly for those seeking a blend of luxury, performance, and open-air driving enjoyment. The M276 V6 engine is known for its durability and relatively straightforward maintenance. While not as collectible as the classic Mercedes-Benz SL models, the E 400 Cabriolet offers a modern and refined driving experience at a more accessible price point. Well-maintained examples continue to command reasonable values in the used car market, appealing to enthusiasts and buyers looking for a sophisticated and capable grand tourer.
