Trials start on two-deck hybrid buses

摘要

The vehicles will undergo real-world trialsrnThe HybriDrive system consists of a generator, an electric motor, and an energy storage system managed by computer. A diesel engine that turns the generator operates independently of the electric drive motor, allowing it to run at nearly consistent speed for optimum efficiency.
