Still amuses me the US diesel is called the 28d where-as everywhere else in the world its called the 20d. Of course not trying to hide the fact its only a 4-cylinder engine while "28" has a long association with 6-cylinder engines. Same sort of spin-doctor nonsense with the new US-spec F15 X5 35d. Everywhere else in the world the engine is called the 30d. In this case they are of course not trying to hide the fact that while the 35d engine in E70 X5 35d was a twin-turbo engine, the 35d in the F15 X5 is the single turbo version - ie the 30d.
