Automatic vans are still something of a rarity, despite growing demand. So it’s good to hear that Mercedes-Benz is now introducing an automatic version of its Citan small van.

From June 2016, selected Citan 112 variants will be available to order with the new 6G-DCT automatic transmission. As I understand it, this is an automated manual transmission, rather than a traditional torque converter auto.

The six-speed dual-clutch transmission consists of two sub-transmissions, each with its own clutch. As one transmits drive to the wheels, the other has pre-selected the next gear. This allows for near seamless gear changes without loss of tractive power, high levels of driving comfort and convenience.

Automated manuals like this are increasingly popular on larger goods vehicles and cars, as they tend to offer better fuel consumption than torque converters and — for goods vehicles — can cope with heavier loads.

Unfortunately, the Citain will only be available as an auto when fitted with the 112 petrol engine. This will limit the uptake of the auto box as most buyers still opt for diesel.

However, if you’re in the market for an automatic petrol van, the Citan 112 6G-DCT will be available to order from June 2016 in long wheelbase panel van and tourer configurations. Official combined cycle fuel consumption is 44.1mpg, while CO2 emissions will be 144g/km.
