In order for the driver to be able to check the efficiency of his driving style and, if necessary, make adjustments, ECO display shows an evaluation of driving style in the instrument cluster speedometer field.
The ECO start/stop function reduces fuel consumption and emissions by switching off the engine automatically when the car comes to a stop (e.g. in traffic jams or at traffic lights).
Significant savings can also come from a series of small contributions. With the aim of reducing the consumption of the E-Class Saloon, the Mercedes-Benz engineers examined all the main components with regard to their energy requirements and found ways of getting them to work even more economically.
Overview of efficient energy management measures:
The current BlueDIRECT V6 and V8 engine generation includes measures such as downsizing, direct petrol injection and turbocharging (8-cylinder models) for fast response. Using the innovative BlueDIRECT engine technology, it was possible to reduce emissions and fuel consumption by up to 24% compared with predecessor engine models.
BlueTEC catalytic converter technology uses the reactant AdBlue® to purify exhaust gases. This makes it possible to reduce nitrogen oxide emissions by up to 90 percentThis diesel technology, currently the cleanest in the world, already today complies with the requirements of the future Euro 6 emissions standard.
 Not available for the E 300 BlueTEC HYBRID.
 The figures shown for fuel consumption and CO2 emissions were obtained in accordance with the prescribed measuring process (Regulation [EC] 715/2007 in its currently applicable version). The figures are not based on an individual vehicle and do not constitute part of the product offer; they are provided solely for purposes of comparison between different vehicle models.
