Diesel – electric hybrid? Of course yes. CNG – electric hybrid? Why not! Daimler Buses, after the launch of the fully electric eCitaro, walks along on the path of mild hybrid technology. The next step is the Citaro hybrid with natural gas drive. Augsburg, in Germany, ordered 6 units of the Citaro NGT hybrid. The very first Citaro G NGT hybrid will roll out in Oldenburg. The vehicle has been chosen also by EMT Madrid and will be deployed in Lubljana (17 units).
Mercedes Citaro NGT, Germany first
Gas engines emit almost no particulate matter and NOx emissions are also very low, Mercedes points out. That’s why the Citaro NGT becomes a valid candidate in the trend towards more sustainable public transport systems. When used in conjunction with biogas or bio natural gas, the Citaro NGT hybrid is almost CO₂ neutral. Augsburg’s public utilities are turning to this technology with their six new Citaro NGT hybrid buses. In Oldenburg, the VWG transport company will be putting the world’s first Citaro G NGT hybrid articulated bus into operation, and best of all, they will be running it on bio natural gas.
