Very useful post:- 
P&G - the FIA Groups and respective car lists (quick explanation)
--------------------------------------------------------------------------------
Many of you are coming to Power&Glory from GT-Legends, which only has three classes listed, TC-65, GTC-65 and TC/GTC-76.
Back in GT-Legends, the class "TC" is "Touring Cars" and the class "GTC" is "Grand-Touring Cars", separated in eras as well, up from 1955 to 1965, and from 1966 to 1976 (please correct me if I'm wrong).
This method of classification is similar to what was used in recent "FIA Modern-Historical" races back in 1994/1995 (that GTL recreated), although the real champ had sub-classes according to engine capacity, which unfortunatly SimBin/Blimey didn't use, perhaps to make it simpler for non-enthusiast gamers, at the cost of slightly less accuracy (comparing to the real championship classes) and resulting in the already known obvious "unbalanced" car performances/comparisons in same class.
For Power&Glory v2.0 (focusing on 1960's racecars), we decided to go full-on into what was used back then, by FIA, for the racecar classes, for Touring, Grand-Touring, Sports-Cars and Prototype classes, getting the different car classes represented and, therefore, more accurately separated and balanced according to each racecar model and/or variation (and respective real life class).
The classic-racing die-hards will almost surely know this by heart but, for those still confused about which car goes in what FIA-Group, or even what each FIA-Group stands for, here's their complete list, and the racecars listed under each of those groups:

We really hope this gets a bit easier for those not accustomated to these classes/groups nomenclatures and respective racecar lists, making it also more understandable according to what was actually used then by the FIA for these cars.
