Mercedes is previewing is new urban delivery can named Citan (with the automaker specifying that its designation comes from the combination of worlds ‘city’ and ‘titan’).
The Citan complements the existing (6.0 to 8.2 tons), Sprinter (3.0 to 5.0 tons), and Vito (2.77 to 3.2 tons) range with Mercedes stating that "We will take advantage of the trend toward city vans, which our brand
will be able to exploit thanks to its attractively priced vehicles and
the high quality of our products and services," "Our typical Mercedes-Benz reliability, 24/7 service, and, last but not
least, our great brand image are key selling points as far as our
commercial customers are concerned."
Described as durable and robust, the Mercedes Citan will premiere at the IAA Commercial Vehicle Show in Hanover in September, while its market launch is scheduled for fall 2012.
The Citan will boast "quality, economy, safety, excellent handling, as well as high fuel efficiency and correspondingly low CO2 emissions" with details regarding powertrains only specifying the fact that customers will have the option of choosing between low-emission, fuel-efficient diesel and gasoline engines as well as a BlueEFFICIENCY package.
An electric version Mercedes Citan is also planned.
