Overview
Community orientation
The X164 GL-Class shares both its spine engines with generations already in the graph: the OM642 V6 diesel (GL 320/350 CDI) and the M273 V8 (GL 450, GL 500). It therefore adds no new occurrence patterns of its own; those patterns resolve onto this generation's 4MATIC configurations at the engine level. See the per-configuration breakdown for which patterns apply to which build window. Community orientation only, not a reliability rating or a purchase recommendation.
