A svelte drop-top companion to the E-Class range of sedans, coupes and wagons, the new Mercedes-Benz E-Class Cabriolet is a luxury convertible that is offered with two engine configurations.
Bigger and more elegantly styled than the outgoing CLK convertible, the E-Class Cabriolet features a traditional cloth softop rather than the folding metal roof that is en vogue on many of its rivals. The roof is thickly insulated, according to Mercedes-Benz, to allow for Bluetooth phone conversations at high speeds with the roof up, and it retracts or raises in less than 20 seconds at speeds up to 25 mph.
For the latest model year, the E-Class Cabriolet gets a pair of new engines that boast increased power and efficiency. The E350 gets Mercedes' new 3.5-liter V6 engine, which puts out 302 horsepower and 273 lb-ft. while returning 19 mpg in the city and 28 mpg on the highway. The E550 replaces its previous big-displacement 5.5-liter V8 for a new, twin-turbo 4.7-liter unit that makes 402 horsepower and 443 lb-ft of torque and nets 16/24 mpg. Both engines are mated to a seven-speed automatic transmission that also includes steering wheel-mounted paddles for manual-style control.
With a coefficient of drag of just 0.25, the E-Class Cabriolet is the most aerodynamic offering in its class. The body is clearly derivative of the E-Class Coupe, but some changes were made to the rear to accommodate the unique trunk panel.
Inside, the E-Class Cabriolet is again almost identical to its coupe brother. The AIRCAP automatic draft stop system, which debuts in the E-Class Cabriolet, uses a wind deflector and a draft-stop mounted behind the rear seats to dramatically decrease windflow in the cabin when the windows are up to ensure an undisturbed driving experience. Mercedes’ heated AIRSCARF neck-level heating system also makes an appearance in the E-Class Cabriolet.

The optional Distronic Plus package adds the aforementioned adaptive cruise control with Brake Assist Plus and Parktronic parking assist that can help guide the car into parking spots via a rear-mounted camera.

Safety Technology
Mercedes-Benz has long been known for its safety features, and the E-Class Cabriolet will only add to that reputation. In addition to ABS and ESP stability control, the car boasts nine supplemental restraints including two-stage front air bags, a knee air bag for the driver and pelvic air bags which work together with curtain and side air bags to provide extra protection for front occupants in dangerous side-impact collisions.
Also standard is an “ATTENTION ASSIST” system that can alert the driver to the first signs of drowsiness, a factor that causes more than 100,000 accidents a year in the U.S.A steering sensor is coupled to smart software that uses 70 parameters to establish a unique driver profile during the first 20 minutes of driving. Between 50 and 112 mph, the system identifies the erratic steering corrections drivers make as they begin to get drowsy and triggers an audible warning and a "Time for a Rest?" message with a coffee cup icon in the instrument cluster.
Optional safety equipment includes the Lane Keeping Assist system, which alerts the driver by simulating a rumble strip vibration in the steering wheel if the car drifts from its lane without the turn signals on. Part of the Lane Tracking Package, it operates at speeds above 37 mph via a system that recognizes lane markings, thanks to a small camera in the windshield and a computer that analyzes the video images.
The Lane Tracking Package also includes Blind Spot Assist, which monitors both blind spots behind and to the side of the vehicle. Whenever a turn signal is activated with a vehicle in the blind spot, the driver gets visual and audible warnings.
