The next generation of the medium-premium car will arrive during difficult economic times, when even wealthy consumers are buying fewer cars.
Mercedes hopes an edgier styling along with more technology will attract buyers.
The E class adds lane-departure warning and sign recognition as safety features. The car will go on sale in Europe in March.
