China Real World and Certified Fuel Consumption Gap Analysis (July 2015 / Clean Transportation Program)

Although the “light vehicle fuel consumption test method" standard was released over ten years ago (in 2004) and light vehicle labeling regulation was release over five years ago (in 2010), most vehicles’ actual fuel consumption is higher than the certified fuel consumption value. The status today is even more complex, since there is little information on actual fuel consumption levels. iCET in collaboration with China&#39s BearOil App collected over 210,000 valid samples of fuel consumption levels reported by drivers from various locations in China between 2008 and 2014 and an average of the reported values was compared with China’s fuel consumption certification. The analysis performed in this study therefore introduces a novel attempt to provide stakeholders with some insights that could hereafter be more thoroughly studied.
