I have a 4WD and it doesn't have the 4WD badge either.
Google is wrong then because we get heaps of calls for them and can't supply enough. Even the prices reflect this and the damaged car auctions. A 4x4 with bring lots more money that a 2WD because everyone wants the diffs.It's hard to grease a universal or centre bearing with no provision to grease it! What is the issue, how many of that mass of X-Trails and Koleos have required rear drive-line replacement? A quick google does not reveal any Koleos problems with 4x4 drive-lines.
