SG bus e500 mmc facelift 12.5m The data comes from Badian: The pure diesel engine-driven version of Enviro500 MMC (also known as E50D) is a three-axle double-decker low-platform bus produced by Alexander Dennis in the United Kingdom, which was officially launched in 2012. In the "Enviro" series, this model is an improved version and successor of Enviro500, which is the first major model change project of the factory; among them, "MMC", written as "Major Model Change", means that this Enviro500 has undergone major changes. (The same situation applies to the improved versions of Enviro400 and Enviro200 Dart in the future, that is, Enviro400 MMC and Enviro200 MMC). Based on the advantages of Enviro500 MMC with low emissions, good performance and high passenger capacity, coupled with the peak period of replacing retired buses by four franchised bus companies from 2014 to 2017 [6] [7] [8], KMB, LWB, Citybus and NWFB have been continuously introduced This model makes this bus very popular in Hong Kong [9]. The total number of Enviro500 MMCs ordered by the above four operators alone is more than 3,500, accounting for more than half of the total number of franchised bus fleets in Hong Kong, becoming the largest number of models in the history of franchised buses in Hong Kong. [ 10] This completely broke the situation of Leyland/Volvo in the Hong Kong franchised bus market in the past few decades, and caused the market share of bus brands such as Volvo, MAN and Scania to slide sharply, laying the foundation for the status of "first brother" of Alexander Dennis in the franchised bus market, and forming a pattern of "one factory and unique". Since 2012, the Enviro500 MMC body can be matched with the improved version of the Volvo B9TL three-axle chassis with square ladder design, but the relevant matching has never appeared in Hong Kong. In addition, this model also provides a hybrid version called Enviro500 MMC Hybrid.
