The recently redesigned Mercedes-Benz E-Class will expand its line-up further for the 2011 model year with the introduction of the E-Class Cabriolet. The competition is relatively small with the greatest rival coming from Audi with its A5 Cabriolet. Both bring a high level of luxury, refinement, and of course, design.
2011 Mercedes-Benz E-Class Cabriolet vs 2010 Audi A5 Cabriolet
The E-Class Cabriolet joins the sedan and coupe versions which were introduced earlier in 2009. The Cabriolet features the same front-end design obviously which gives it the most aerodynamic design in the segment. It achieves a drag coefficient (Cd) of 0.28 versus the E-Class sedan's Cd of 0.25 and the coupe's Cd of 0.24. While not as high as the other E-Class versions, it still beats the A5's Cd of 0.31. The A5's familiar design is the same as most Audi's these days with the single-frame trapezoidal grille being the vocal point. LED-lined headlamps are another familiar design cue with eight LEDs lining the bottom of each side.
Both models look great with the top down while retaining each model's coupe proportions and design. The side of the E-Class features the same creases and sculpted rear fender which visually creates a sleek forward appearance. The top goes up and down within 20 seconds at speeds up to approximately 25 mph. The A5's top beats the E-Class' with 15 seconds to open the top and 17 seconds to close it at speeds up to approximately 31 mph.
Both Mercedes and Audi opted for traditional soft tops rather than hardtops that are getting more popular these days. The fabric roofs allow for reduced weight compared to metal roofs resulting in a lower center of gravity. To increase safety needed for soft tops, the E-Class' A-pillars are reinforced with two high-strength steel tubes and headbags, a first for Mercedes convertibles. Roll-over bars are also incorporated in the rear head restraints that deploy within a fraction of a second. The A5 features roll-over aluminum braces behind the rear headrests that are spring-activated and lock into place in the event of a rollover. An acoustic soft top is standard on the E-Class and optional on the A5 to aid in lowering wind and road noise.
The E-Class features Mercedes' new AIRCAP automatic draught-stop system which reduces interior turbulence. AIRCAP consists of an extendable wind deflector with a net and a draught-stop between the rear seats that combine to elevate the free flow above the interior, increases back pressure, and reduces backflow all to reduce interior noise with the top down. Mercedes' AIRSCARF system is also included which is a heating system at the neck level. Audi also includes a similar system for enjoying the top down even in colder temperatures.
Both the E-Class and A5 feature taillights that look more luxurious than your typical convertible. The crystallized look of the E-Class's taillights scream upper class while the A5's taillights feature LEDs (of course). Dual exhaust systems on both cars emphasize performance.
Both interiors have a similar design with the information screen housing connected to the gauge cluster housing. The A5's dashboard is a little more driver-oriented with the center stack curved slightly toward the driver. The E-Class' interior looks more upscale with buttons and gauges that look like jewels. Both include the features one would expect in a luxury car such as a high-end audio system (Bang & Olufsen in the A5), Bluetooth, iPod integration, voice-activated navigation, and adaptive cruise control to name just a few.
