Even today the Citaro understands how to represent modernity and innovation. Its recipe for success is simple: meet the customer's needs. The second Citaro generation followed the first at the end of 2005/2006. Among its star qualities which won customers over from the get-go were its new axle construction and a completely reworked "face". From then until now the Citaro has maintained the kick of its development engine. And the customers are not the only ones who recognise its appeal. Journalists, independent trade experts and drivers in particular appreciate its features. That's why it won the reader's prize of publisher ETM's "Commercial Vehicle of the Year" 10 times, for example. The readers of "Busfahrer" magazine voted it the "Best Bus of 2009", Dekra awarded it an environmental prize, the environmental office of the German state of Baden-Württemberg gave it the F-Cell Award and an international jury selected it as the "Bus of the Year 2007".

Recently the trade magazine Omnibusrevue wrote of the Bus Euro Test: "The Mercedes-Benz Citaro sets the bar for the rest of the sector." No other vehicle concept has made an impact on the bus market like the Citaro has. It is without a doubt the "Bus of the Decade".

The 30,000th Citaro is an embodiment of the essential attributes to which the model range owes its success: flexible, cutting-edge, environmentally friendly and passenger-oriented. The Citaro G CNG, sporting silver metallic paintwork offset with traffic orange, is fitted with an environmentally friendly natural gas engine. The M 447 (h)LAG engine rated at 240 kW complies with the EEV (Enhanced Environmentally friendly Vehicle) emissions standard without a particulate filter. The voluntary EEV emissions standard defines the most stringent European emission levels at present, with limits set below those of the Euro 5 standard. Customers have been able to order the alternative CNG drive from the modular system for their Citaro ever since 1998.

The light and pleasant interior of the 4-door Citaro is equipped with an interior and door surveillance system. Two door cameras on doors 3 and 4 transmit images to the TFT monitor at the driver's workplace. This monitor also displays the image from the rear-view camera when the vehicle is reversing. The driver's entire workplace is separated from the passenger compartment by a driver's cab. The overhead air conditioning system provides separate climate controls for the driver's workplace and passenger compartment.
