The Mercedes-Benz E-Class has long been recognized as the German marque’s backbone, particularly in the American market. Consistently lauded as a benchmark in the midsize luxury segment, Mercedes-Benz continually expands the E-Class lineup, with the 2011 E-Class Cabriolet embodying open-top sophistication. Let’s delve into whether this convertible variant upholds the E-Class legacy while offering an exhilarating drop-top experience.
From a design perspective, the transition to the 2011 Mercedes-Benz E550 Cabriolet was seamless. Retaining the E Coupe’s expressive lines and muscular rear haunches, the Cabriolet exudes a captivating presence. By removing the fixed roof from the elegantly styled two-door, Mercedes-Benz has amplified the drama, crafting what they term a four-seat, four-season convertible.
In a departure from retractable hardtops, Mercedes-Benz opted for a traditional soft top, similar to the Audi A5 Cabrio. However, this isn’t just any ragtop. Its three-layer construction provides exceptional sound insulation, rivaling some hardtops. The fully automatic top operates swiftly, opening or closing in approximately 20 seconds, even at speeds up to 25 mph.
Mercedes-Benz is renowned for innovation, and the E550 Cabriolet is no exception. The AIRCAP automatic wind deflector system is a standout feature. Activated by the driver, AIRCAP comprises two main components: a deflector extending from the windshield header and a windscreen rising behind the rear headrests. This system effectively redirects airflow over the rear passenger area, virtually eliminating wind buffeting, enabling comfortable conversations even at highway speeds for both front and rear occupants.
Further enhancing its four-season appeal is the upgraded AIRSCARF system. This neck-level heating system, with air vents integrated into the front headrests, proved remarkably effective in extending the top-down driving season into colder months, making late winter drives surprisingly pleasant.
Mechanically, the E-Class Cabriolet closely mirrors its coupe sibling. While the E350 houses a 3.5-liter V6 engine, the E550 boasts a potent 5.5-liter V8, generating 382 horsepower and 391 pound-feet of torque. Both engines are paired with a seven-speed automatic transmission featuring manual shift mode. Despite its all-season aspirations, all-wheel drive is not available.
On the test track, the 550 Cabriolet demonstrated impressive acceleration, sprinting from 0 to 60 mph in just 5.1 seconds and completing the quarter-mile in 13.6 seconds at 105 mph. These figures are remarkably close to the Coupe’s performance, despite the Cabriolet carrying an additional 120 pounds. The V8 engine delivers abundant power across the rev range, and gear changes are both rapid and smooth.
The E Cabriolet also exhibits torsional rigidity comparable to the E-Class hardtop, contributing to a solid and refined driving experience. Utilizing a familiar front strut suspension and rear multi-link setup, the convertible sacrifices nothing in terms of agility or responsiveness. Braking performance is also commendable, with average stopping distances from 60 mph at 123 feet, achieved with unwavering stability.
In everyday driving scenarios, the Cabriolet maintains the planted and nimble feel characteristic of the E-Class family. It masterfully blends an engaging driving experience with a supremely comfortable ride, free from unwanted rattles or cowl shake. A minor steering wheel vibration at higher speeds was the only slight imperfection noted.
Mirroring the Coupe, the Cabriolet’s four-seat cabin combines traditional Mercedes-Benz luxury with a hint of sporty flair. Burl walnut trim and a dark finish around the five-gauge instrument cluster immediately draw attention. The standard front seats, upholstered in weather-resistant leather, offer excellent support and include 10-way power adjustability and 4-way lumbar support.
Safety is paramount, with features like Attention Assist, which alerts drowsy drivers. In addition to standard airbags, the Cabriolet includes front pelvic airbags and a driver’s knee airbag.
The COMAND interface, a Mercedes-Benz standard, manages the audio system, Bluetooth connectivity, and optional navigation.
Rear legroom in the Cabriolet is limited, mirroring the Coupe. However, smaller adults can comfortably occupy the rear seats. While the rear seats do not fold flat like in some competitors, a small pass-through to the trunk enhances practicality.
Cargo capacity is generous for a convertible, thanks to the soft top design. With the top raised, the trunk offers 13.8 cubic feet of space, only slightly less than the coupe, and remains adequate even with the top down.
Fuel economy is estimated by the EPA at 15 mpg city and 23 mpg highway for the E550, requiring premium fuel. Real-world testing yielded a respectable 20.1 mpg in mixed driving conditions.
The 2011 Mercedes-Benz E550 Cabriolet starts at an MSRP of $65,675, a premium over the coupe variant. However, for that price, you gain a world-class convertible that retains the presence, technology, refinement, and driving dynamics of the E-Class coupe. Combined with innovative features like AIRCAP, the 2011 Mercedes-Benz E-Class Cabriolet elevates the benchmark for luxury convertibles.
