Why the Mercedes Citaro is the Future of European Urban Bus Services

- Leadership - Oct 07, 2014

Daimler continued its industry-leading performance after its Mercedes-Benz Citaro Euro VI received the "Green Bus Award 2014" at the IAA, the world’s leading exhibition for commercial vehicles.

The award goes to the urban bus displaying the lowest fuel consumption on the demanding "Omnibusrevue" test route in Berlin, with the German company being awarded the honour for the third time in four years.

The vehicles are tested on a slightly modified variant of urban bus line 200, which entails a highly demanding route limited exclusively to inner-city roads.

A continuous succession of bus stops and traffic lights impose the highest demands on the driver and the deployed technology.

World First

The urban buses from Mercedes-Benz feature the impressive new BlueEfficiency Power engine line comprising six-cylinder in-line engines with a displacement of 7.7 and 10.7 l. In 2012 the Citaro was the world's first regular-service bus to meet the Euro VI emissions standard.

Independent studies have shown that in practice the Citaro comes in considerably below these limits. Pollutants are now barely detectable in its exhaust emissions.

The engines impress with their agile response and impressive power delivery combined with very smooth running. With the revs dropped further, the Citaro Euro VI operates even more economically and quietly.

Lowered entries, demand-controlled air compressor, electronically controlled compressed-air delivery and AdBlue injection without compressed air all help to lower fuel consumption.

At the same time numerous other measures have reduced the weight – despite complying with Euro VI, the Citaro's bodyshell is even more robust than previously and lighter.

It also saves fuel. In the autumn of 2012 the Citaro Euro VI demonstrated this in an extensive test. In the "Record Run Buses", fuel consumption under practical conditions was 8.5 percent lower than for the comparable preceding model.

Hartmut Schick, head of Daimler Buses, said: " This endorsement once again underscores Mercedes-Benz's aspiration to set standards in the market. Both our new generation of vehicles and the fuel-efficient BlueEfficiency engines are representative of our pronounced sense of responsibility as a bus manufacturer towards people and the environment. For our company, shaping the future of mobility is a challenge which we address with dedication and passion."

With 40,000 units produced to date, the Citaro is the Mercedes-Benz bus with the highest production output of all time.
