In addition to the by-now expected anti-lock brakes, traction control and Electronic Stability Program, the E-Class adds the world's first electronic brake system. The brake pedal "talks" to a computer that opens pressure valves at each wheel. An old-style hydraulic system is included as a back-up, in case of system failure. A couple of other techno-features include Distronic Adaptive Cruise Control that uses radar to maintain a set distance from a vehicle in front, and Keyless Go that allows the driver to unlock the car by touching the door handle and to start it by touching the gearshift. There is no shortage of convenience and safety technology here.
The E-Class' interior is among the best appearing in the industry, with a beautiful combination of colours and tones, and flowing dashboard and door panel design. Overall fit and finish is beyond criticism, as one would expect from Mercedes. In general, the ergonomics of the E-Class are very good, with acceptable outward vision and all controls within easy reach. Mercedes has continued with some questionable control solutions, however, among them the twist wiper control on the end of the turn signal lever that requires the driver to remove his or her hand from the steering wheel to operate it.
