Environmentally compatible concepts
BlueEFFICIENCY from Mercedes-Benz stands for pioneering efficiency technologies as well as innovative packages of measures based on optimising fuel consumption and emission levels.
BlueEFFICIENCY measures
The BlueEFFICIENCY measures are comprehensive vehicle optimisations which save fuel and ease the burden on the environment. The new B-Class also combines the most efficient engines with the optimum aerodynamics and energy management features available to keep fuel consumption to a minimum.

Aerodynamics The new B-Class is very aerodynamically efficient which means wind noise is hardly noticeable. With its aeroacoustics the new B-Class has further enhanced its leading position in its segment. The Cd value was significantly improved in the new B-Class with a figure of 0.26. The B-Class continues to lead its segment with regard to its exceptionally low interior noise levels. The internal wind noise index as assessed by the development department has improved by six percent in comparison to the previous model series.

Diesel particulate filter The diesel particulate filter filters up to 99 percent of the soot particles from exhaust emissions and does not need any additive. Filter regeneration is initiated by the electronic engine management and controlled by the pressure and temperature of the exhaust gas at the filter. The separated particulate matter on the filter duct walls is burned off at exhaust gas temperatures in excess of 600 degrees Celsius. Filter regeneration is initiated by an increase in the exhaust gas temperature and goes unnoticed by the vehicle occupants and other road users. |

Intelligent energy management Significant savings can also come from a series of small contributions. With the aim of making vehicles of the new B-Class more fuel efficient, the Mercedes-Benz engineers examined all the main components with regard to their energy usage and found ways of getting them to work more economically.

Tyres with optimised rolling resistance The rolling resistance of the tyres has a big influence on a vehicle’s consumption. For this reason, Mercedes-Benz deploys tyres with low rolling resistance in the new B-Class as well. They are formed in a different way and use a different rubber blend to conventional tyres. With unchanged handling and braking characteristics, the rolling resistance can be markedly reduced with them. |

|
ECO start/stop function The optimised ECO start/stop function reduces the vehicle's fuel consumption and emission levels by switching off the engine when the vehicle is at a standstill. The engine restarts automatically as soon as the driver depresses the clutch pedal fully. |
Efficiency technologies in the new B-Class
The latest-generation CDI diesel engines display compelling performance characteristics coupled with low consumption levels. Injection pressure has been increased, smoothness of operation enhanced and noise levels optimised, while reduced compression makes for lower emission levels.
The completely redeveloped 4-cylinder powerplant with direct petrol injection, variable valve timing and turbocharger, offers outstanding torque and power in two stages and exemplary quiet-running not to mention appropriately low fuel consumption and emissions.
Environmental certificate
Mercedes-Benz is the only automotive brand in the world to have received an ISO-standard Environmental Certificate. For this certification, the vehicle models have to meet strict requirements and undergo stringent controls in their development, production and recycling. Our goal is to make environmental protection objectively measurable and to make it possible for you as the driver to experience it concretely.
