Evolution of early Le Mans classes...?

[pgtr]

Got no response on the GT/LeMans board - thought I'd try here....


Hello,

Been looking at different classes over the years which of course creates some inevitable confusion :-) on my part.

From 1961 to 1962 they went from

Class S and GT ('61) to
Class EXP and GT ('62).

Was EXP completely new or was there any connection to the previous S class? Or did the cars that used to be in the previous S class get more or less morphed into GT?

It appeears that EXP continued on in following years as P ('63+) and SP ('68+).

----

Also Class S did reappear in 1966. But this Class S seems to occupy more 'exotic' and 'super cars' or very low production race cars vs the more mass produced sports cars of the old '61 Class S. True?


Thanks,

Could anybody suggest 'where' I might find such information? Other websites? Book? ...?

Thanks!
