Mercedes-Benz has traditionally played a pioneering role in the development of environmentally friendly, innovative drive system technologies. With BlueEFFICIENCY Power technology, Mercedes-Benz has again set benchmarks. Now, the advanced technology from complete bus systems development is also available in the OC 500 RF and ensures lower emissions and even higher economic efficiency. That's because, thanks to the efficient and powerful BlueTEC® engines, the engineers have succeeded in further reducing the fuel consumption, despite introducing Euro VI technology. Plus, the usable service life and maintenance intervals were also able to be increased. This results in excellent total cost of ownership throughout the whole life of the bus.
