The W639 V-Class (Viano) shares every one of its engines with generations already in the graph: the M112 and (facelift) M272 petrol V6 (Viano 3.0/3.5), the OM646 and (facelift) OM651 four-cylinder diesel (Viano CDI 2.0/2.2) and the OM642 V6 diesel (Viano CDI 3.0). It therefore adds no occurrence patterns of its own; those patterns resolve onto this generation's configurations at the engine level. The commercial Vito shares this platform and engine range. See the per-configuration breakdown for which patterns apply to which build window. Community orientation only, not a reliability rating or a purchase recommendation.
