English   Mercedes-Benz Citaro with new Euro VI engines

Choice of two state-of-the-art transmission systems

Both new engines have fully automatic torque converter transmission systems, as before. Voith and ZF transmissions sytems are available, both in the latest version for compliance with the Euro VI exhaust emissions standard. The torque converter characteristic curve is adjusted for the low engine speeds in the new engines.

Euro VI compliance with up to 5 percent lower fuel consumption

In spite of Euro VI requirements and the associated exhaust gas aftertreatment process, the fuel consumption of the new Citaro is even lower than its Euro V predecessor, which already had excellent fuel economy. Measurements in practical operating conditions indicate consumption savings of up to 5 percent, with a corresponding reduction in CO2 emissions. For an operator with average mileages and fuel costs, this means extra savings of around 800 to 1400 euros per year.

Recuperation module for fuel savings

When it comes to the outstanding economy of the new Citaro, the development engineers have excelled themselves, with a new fuel recuperation module (24 volts) for even more fuel savings. The free electricity generated during the “overrun” phase will be stored, and used for energy supply to the vehicle during the “traction” phase. This will ease the load on the alternators, lengthening their service life, and further reduce fuel consumption.

The energy will be stored in “supercaps”, double-layer capacitors with a power rating of 6 kW and a capacitance of 1 Ah. This process alone will achieve a reduction of more than two percent in the fuel consumption and CO2 emissions of the Citaro, depending on operating conditions.
