Two Mercedes-Benz Citaro G BlueTec Series Hybrid Buses in Field Test With Hamburger Hochbahn Transit Company
The Hamburger Hochbahn Transit Company is running two Mercedes-Benz series hybrid Citaro G BlueTec Hybrid buses in a field test. The articulated Citaro G BlueTec Hybrid (earlier post) can travel for stretches solely on electric power provided by the Li-ion battery pack without using its diesel engine.
The 18-meter hybrid bus is driven by four electric motors which are integrated directly into the wheel hubs on the center and rear axles, with a combined output of 320 kW. The combustion engine has only 4.8 liters displacement as opposed to the standard 12, and its output of 160 kW is around one-third lower. Instead of 1,000 kg, it weighs only 450 kg.
The energy storage unit in the new Mercedes-Benz Citaro G BlueTec Hybrid is a lithium-ion battery pack with a maximum output of 240 kW and, with a weight of less than 350 kg, it’s also relatively light.
The two Citaro G BlueTec Hybrid buses in Hamburg are the first such vehicles to be sold and also used within the framework of a customer field test in Germany. This year, Daimler will test around 30 Citaro G BlueTec Hybrid buses in selected model regions. The buses will demonstrate their suitability for everyday use by operating in regions with different topographies and speed profiles.
