Mercedes has announced a series of updates to the Citan.

Set to go on sale in June, the updated model meets Euro 6 emissions standards without having to use SCR technology.  This was achieved by using "internal engine measures," a storage-type NOx catalytic converter and adding a standard BlueEFFICIENCY package with an ECO start/stop function.  Thanks to these changes the fuel consumption for diesel-powered models has dropped to 4.3 L/100 km (54.7 mpg US / 65.6 mpg UK) while the torque output has climbed by 20 Nm (14 lb-ft) per engine.

Besides the eco-friendly engine tweaks, the model can be equipped with a rearview camera and a new GPS navigation system with 3.5-inch display. Long variants are also available with a new "split tilting skylight" above the front seats.  Last but not least, the Citan crewbus has been renamed the Citan Tourer to echo the nomenclature used on the Vito.
