The series hybrid bus HFF6110GZ-3 jointly developed by Anhui Ankai Automobile Co., Ltd and Shidai Huatong Technology Co., Ltd has been running satisfactorily since it was put into commercial operation on Shanghai 92B public transport route. As of the end of February, this kind of bus has been running safely without fault for over 6500km (still running during the Spring Festival). The power systems of this bus match with each other appropriately and are characterized by good safety and liability, obvious saving of petrol, low noise, comfortable seating, auto gear and simple driving. It is highly praised by passengers and drivers.
