Hybrid Sydney Bus

I photographed a hybrid bus on trial by the NSW State Transit Authority on the 370 route in Annandale, in the Sydney inner west. A media release described this as being a deseil electric hybrid which can run on battery power alone. But another option is a mild hybrid, running on natural gas, with battery power as a supplement.

"The hybrid bus will run on a small diesel generator, which either charges the buses’ electric battery or provides power directly to the electric motor if the battery is full. The motor, not the generator will drive the bus".
