I don't thinkthe 'S' really stands for anything. It just suggests a sporty model. Other cars have been L,GL, GLS, especially Fords. I was told this was Lux and Grand Lux etc. but what about XL and XLS? Jaguars have XJ and XJS. We also have GLI, GTI, GTJ, LS, CD, CDR, SE, SEi, HDi, RS, SL, SLK etc, etc. I'm sure some have a meaning, but not all!
As to the 'S', I agree with the others who have expressed a view that it probably was just a useful way of identifying the manual V8. I recall discussions when they were first anounced and both Sport and Syncromesh were mentioned then, but nobody could be definite. More tended to 'sport' than 'syncromesh', and I think that was more in line with Rover's advertising for it.
With regard to the P4, Michael Bobbitt states in his book that, with repsct to the 105 R + S, that R stood for Roverdrive and S for "syncromesh, and not speed or sport as is often quoted". However, there are a few errors in that particular book , so whether that is 100% accurate, who knows! Certainly, the general view amongst P4 people in the late 60's and early 70's was Syncromesh. That doesn't really fit with the P6 though, because, as Chris says, the 2000S was being considered long before the 3500S 'syncromesh', and the then-current 2000 already had a manual gearbox.
I agree that many are made up, although many do imply a 'specification', of sorts, even if in the original language; ie. Merc SL = Sport Leicht (sport light), SLK almost certainly = Sport Leicht Klasse (whether that is actually true is a different argument), GT = Grand Tourer, RS was Rally (or Rallye) Sport for Ford, XJ for Jaguar originated from eXperimental Jaguar (originally an engine code).
Were there any DLs (I can't recall), which, if it did exist, might have originated from DeLuxe (when there used to be DeLuxe, Super etc), so maybe GL was 'GrandLuxe'!!
