Tang Yuxiang, chairman of Yutong Group, has drew up development goal of energy-saving and emission reduction as early as 2005. In 2009, first Yutong Cup Driver Energy-saving Competition which was also the first like activity in transportation industry was held. The Yutong Cup is an omnibearing show of their efforts towards their goal.

Towards how to save energy and reduce emission better, Mr. Dong, assistant director of test center introduced that they usually analyze the root and key points of energy-saving and emission reduction. And they concentrated on how to transfer the energy made by fuel inflaming to effective kinetic energy.
Engine Thermal Management system is their efforts for many years. And this is a complete technique structure to promote conversion efficiency of thermal energy, involving optimizing transmission system, aerodynamics as well as hydrokinetics.
As the establishment of Yutong national test center and introduction of international advanced foundational experimental facility and tools, research on energy-saving and emission reduction is gradually stepping down.
Yutong summarized influential factors of fuel economy into twelve sectors, including engine, induction system, fuel system, cooling system, exhaust system, transmission system, fuel consumption of engine fittings, use of air conditioner, choice of tyres, resistance of body, vehicle drive and maintenance, and quality of fuel and lubricant.

Till now, Yutong has established technology evaluation system to vehicles, and as many as sixteen factors will be considered to each vehicle.
As they research more about energy-saving and emission reduction, Yutong found that Driver’s driving technology influence fuel consumption a lot. Although they have summed up a fuel-saving driving guide years ago, the effects were not distinct.

"Some old drivers have rather good driving technique, as current bus technique is changing, many traditional methods are no longer suitable,” introduced Mr. Dong. “Many drivers will still follow their experiences without quantification of driving statistics. So we are trying to infuse the knowledge in textbooks to them. It turned out Yutong Cup is a very good way to do this.”
In addition, they have raised more driving tips in special conditions, such as nighttime driving, driving in mountain areas, slide driving, seasonal driving, driving methods for public buses, and driving when turning, up sloping and so on and so forth.
From guide on fuel-saving driving to Yutong Cup, it turned out that efforts by Yutong were effective and deserved.
