Developed specifically for Europe, tested and proven under the harshest conditions from the Arctic Circle to southern Europe, the innovative BlueEFFICIENCY power drive technology is used in Citaro city buses. The powerful, efficient Euro VI engines ensure unrivalled economy. In spite of higher requirements, it was possible to further reduce fuel, engine oil and AdBlue® consumption. In a Dekra test, the Citaro Euro VI with the Mercedes-Benz OM 936 h and 220 kW (299 hp) engine competed against the Euro V predecessor models with the OM 906 hLA (210 kW/286 hp) and OM 457 hLA (220 kW/299 hp) engines. The result: the developers succeeded in reducing consumption by 8.6 per cent. At the same time, the reduced consumption protects the environment through lower CO₂ emissions.

The first scheduled-service buses with Euro VI.
The perfect drive.
BlueEFFICIENCY Power engines with BlueTEC 6 are not only impressive because of their enormous economic efficiency, but also because of their excellent environmental compatibility. The engines ensure a drastic reduction in nitrogen oxides and particles in exhaust gas. Pollutants have reached the detection limit as a result. Independent investigations confirm that Citaro emission levels are even considerably lower than Euro VI limits under practical conditions. An impressive advance that once again sees the public service bus exceeding all expectations.
A real eco system.
Other components such as the lighting system, optional air conditioning system or the electrically operated pivot-and-slide doors also have an effect on fuel consumption. The Citaro also has optimised battery management on board. All components are perfectly tuned to one another using intelligent electronics.
A bus only earns money when it is on the road.
Everything in the Citaro is designed to help avoid expensive down times. The filters for the air extraction in the driver's area are easy to access and have a high volume which means long intervals between cleaning. All the essential components are arranged to be simple and easy to access. This ensures long maintenance intervals and short repair times.
* The air-conditioning system and the refrigerator of your vehicle are filled with R-134a refrigerant and contain fluorinated greenhouse gas. The warning signs with detailed information about the refrigerant used are located on each device. To this end, please observe the vehicle's Operating Instructions.
