Up to 65.7 mpg* – the Citan also sets a good example when it comes to fuel consumption  .
The engine line-up has the right solution for every requirement profile. Available only with front-wheel drive, there is a choice of a high-torque 75 hp (55 kW), 90 hp (66 kW) or 110 hp (81 kW) diesel power plant or an advanced 114 hp (84 kW) petrol engine for the Citan panel van.

The manual transmissions offer a high level of ride comfort and have a positive effect on fuel consumption. There is currently no option for automatic transmission.
The Citan is only available with front-wheel drive. The small turning circle of 10.1 m (compact version) , 11.2 m (long version) or 12.4 m (extra-long version) makes for a more relaxing driving experience in urban traffic.
The Citan with BlueEFFICIENCY .
Mercedes-Benz is committed to shaping the future of mobility responsibly and sustainably. And the Citan is part of this commitment. In city traffic especially, the Citan more than lives up to this billing – by reducing CO2 emissions and fuel consumption thanks to innovative BlueEFFICIENCY technologies.
BlueEFFICIENCY technologies are intelligently-combined measures to help reduce consumption and emissions. As the customer you benefit from these in several ways. For one thing, the drive systems are more efficient and therefore use less fuel. For another, the CO2 emissions are reduced, as a result of which the vehicles enjoy better prospects for the future with regard to future emissions directives.
BlueEFFICIENCY is fitted as standard on all petrol variants and is optionally available for the diesel engine models. It includes, amongst other features, battery and alternator management, an ECO start/stop function and, depending on variant, tyres which have been optimised for rolling resistance  .
