Its not in my book, it how cars are made. Some cars start with FWD and become AWD, X-Drive is RWD which with addition of some components became AWD, other cars are designed as AWD from ground up.
Its obviously more expensive to design AWD car from ground up, so car manufactures "convert" FWD/RWD to AWD with relatively cheap Haldex or Haldex-like systems. VW, Volvo, BMW use pretty much the same system, whereas Audi, Subaru, and Mitsu use something different.
edit: now torque vectoring and electronically controlled center diffs. is something different and is more advanced. Currently Audi, Mitsu, Subby, and Acura use those.
