Mercedes-Benz's E-Class range has long been the automaker's bread-and-butter lineup. A direct descendant of the rattly, yet long-lasting diesel sedans of the '70s and early '80s, the E-Class has seen considerable evolution over the years, leading to the highly refined vehicles of today.
For the latest model year, the E-Class sedan (along with its coupe and convertible siblings) receives a pair of new engines that are significantly more powerful and fuel-efficient than the units they replace. E350 models receive an all-new 3.5-liter V6 that utilizes direct-fuel injection and a high compression ratio to achieve 302 horsepower and 273 lb-ft of torque. E550s get a twin-turbo 4.6-liter V8 that produces 402 ponies and 443 lb-ft of torque.
Both engines hook up to a smooth-shifting seven-speed automatic transmission that helps return 18 mpg in the city and 25 mpg on the highway with the E350 and 16/24 mpg for the E550.
The rest of the E-Class was also redesigned recently, representing a significant step up from its predecessor. In addition to an all-new interior and exterior, the E-Class packs a number of new or improved high-tech features, as is typical of Mercedes-Benz.
The sedan's all-new body doesn't just look different; it also yields a number of functional improvements. Aerodynamics were a big focus of the redesign, and Mercedes was able to achieve a drag coefficient of only 0.25, making the car the most aerodynamic luxury sedan, the company claims. Moreover, the new body is 30 percent stiffer, resulting in more precise handling.
Standard and Optional Features
Notable standard features include a power sunroof, real wood trim, 14-way power adjustable front seats and a COMMAND infotainment system with a 7-inch display screen.

Safety
Mercedes-Benz has long been known for its safety features, and the E-Class 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.
