Mercedes-Benz Citan (Germany, 2012-present)

The Mercedes Benz Citan is an urban delivery van. It has a load space of up to 3.8 m³ and a maximum payload of 800 kg. According to Mercedes, the Citan is a smooth progression on from the Mercedes Benz Vito. The 2012 Citan comes in three lengths and three variants, the Citan panel van, Mixto and Crewbus.

The Citan is available with four different engine set-ups. The turbodiesel direct-injection Mercedes Benz OM 607 with a displacement of 1.5 l is supplied in three different output levels:

    Citan 108 CDI, output 55 kW (75 hp), torque 180 Nm
    Citan 109 CDI, output 66 kW (90 hp), torque 200 Nm
    Citan 111 CDI, output 81 kW (110 hp), torque 240 Nm

The range is complemented by the turbocharged M 200.71 petrol engine with a capacity of 1.2 l:

    Citan 112, output 84 kW (114 hp), torque 190 Nm.

Diesel engines

The four-cylinder diesel engines with a displacement of 1461 cm³ have square bore/stroke dimensions with a 76 mm bore and an 80.5 mm stroke. An overhead camshaft controls the valves. Fuel is conducted into the combustion chambers at a maximum pressure of 1600 bar by electronically controlled direct injection with common rail and piezo-controlled injectors. Turbocharging is carried out by an exhaust gas turbocharger with intercooling, or by means of variable turbine geometry in the Citan 111 CDI. The ECO start/stop function is available as an option. The diesel engines achieve maximum engine output at 4000 rpm, and maximum torque at 1750 rpm.

The diesel engines comply with the Euro V emissions standard. The maintenance intervals are at 40,000 km.

Petrol engine

As an alternative to the diesel engines, a turbocharged petrol engine with direct injection is also available. This engine complies with the Euro V emissions standard and features a three-way catalytic converter. The four-cylinder engine with 1.2 l displacement counts on an aluminium crankcase, four-valve-per-cylinder design and two overhead camshafts. Thanks to the 73.2 mm bore and 72 mm stroke (1192 cm³ displacement) the engine has square bore/stroke dimensions.

The engine's exhaust gas turbocharger guarantees 90 % of the maximum torque at 1500 rpm. The engine achieves the maximum torque of 190 Nm within an engine speed range of 2000 rpm to 4000 rpm. The maximum output of 84 kW (114 hp) is reached at 4500 rpm.

BlueEFFICIENCY technology with an ECO start/stop function is standard in the petrol engine. It automatically switches off the engine in standby phases. This occurs when the transmission is in neutral, when the clutch is not depressed and speed is below 4 km/h. The engine starts up again as soon as the vehicle begins to roll again or the driver depresses the clutch.

For the two lower-output diesel engine variants, power transmission is handled by a five-speed manual transmission. The petrol engine and the high-power diesel both use a six-speed manual transmission. In all cases the driver shifts gears using a joystick-type gear lever in the centre console. The vehicles feature front-wheel drive.

Both transmissions have double-cone synchronisation in the two lower gears and also the reverse gear is synchronised for both transmissions.

A shift point display which supports the driver comes as standard. It uses an arrow pointing upwards or downwards to show the most sensible gear change with regard to fuel consumption and driving dynamics. The fuel tank's capacity is 60 l.

The combined fuel consumption of the Citan 108 CDI BlueEFFICIENCY and Citan 109 CDI BlueEFFICIENCY is 4.3 litres/100 km in accordance with NEDC. Accordingly, the Citan 108 CDI BlueEFFICIENCY and the 109 CDI BlueEFFICIENCY emit 112 g/km CO2.

BlueEFFICIENCY package

The BlueEFFICIENCY package comes as standard for the petrol engine and is also optionally available for the diesel engines. It reduces the fuel consumption values by up to 0.4 litres to 4.3 l/100 km. BlueEFFICIENCY includes, among other things, the ECO start/stop function as well as battery and alternator management. Thanks to the alternator management, braking energy can be recovered. The heart of battery management is a sensor which continuously determines data such as current ratings, voltage and temperature of the vehicle's battery. These values help to ensure efficient generation, intelligent distribution and optimised storage of energy.

The vehicle, depending on the variant, also has rolling-resistance optimised tyres. These tyres in the 195/65 R 15 size are included in the scope of the BlueEFFICIENCY package for variants with a payload capacity of up to 650 kg.
