point is that the acronym was first used in Germany, hence the meaning Renn Sport. Obviously UK cars or Japanese cars like the sound and the kudos of the acronym and try to capitalise on that but adding it to their cars and think of anything in English that might fit RS, like racing sport or race sport or Rallye Stallion, but the original meaning has not changed.

The same goes for GTO which was introduced by Ferrari (Gran Turismo Omologato) and then used by Pontiac. However I don't think that Pontiac ever came up with a new meaning for the "O" in this acronym.
