No, the World Championship was run according to Formula 2 rules. So it were
F2 World Championship Races.
Note: "Formula 1", "Grand Prix" and "World Championship" have not always meant the same thing like it is today.
"Formula 1" races, that were no "Grand Prix" and were not round of the "WC" -> many non-championship races like the "Race of Champions"
"Grand Prix" races, that were not Formula 1 and not round of the "WC" -> Macao GP, Monaco GP 1952, Formula Libre etc.
"World Championship" races that were not Grand Prix and not Formula 1 -> Indy 1950 - 1959
I think a "Formula 1" race is only when a race is explicitely open for Formula 1 cars. This includes all occasions when cars from other categories appeared (but still under F1 rules), as long as they do not exceed the F1 limits, like a number of F2 or even a few sports cars in the late fifties.
This is still quite a difference to Formula libre races, where Formula 1 cars just "happen" to fall under the rules (which virtually don´t exist...).
Other case is when a race is open to more than one category of cars (combined F1 / F2 race like the German GP in the late sixties). This is easy as long as the "other" category is regarded "lower" than the Formula 1, so that we could still list such races as proper F1 events with a proper Formula 2 class (and seperate classification) included. But things start to get complicated, if the "other" Formula is not automatically less competitive, like Formula 5000 (which at least theoretically has an engine cpapcity "advantage") AND if there is no seperate classification. In this case I would tend rather towards the "Forumla Libre" designation.
So a long-term question to me has always been how to deal with the South African races. When were they "Formula 1" and when something else?
In the early years they were open to 1500 cc, so they are usually listed as "F1" events, but as I understand they were open to four-cylinder cars only, which is an additional restriction on the Formula 1 rules. So I would not count this as "proper" F1 races (With the exception of the South African Grand Prix of course, which did not have this restriction).
Then we have the Rand GP in December 1965, already run under the new 3,0 litre Formula 1, which AFAIK became officially valid only on 1.1.1966. So taking it strictly can we count this as a Formula 1 race, when still the old 1500 cc rules were in place?
The following years it seems, that the South African series was run to "full" F1 specification, so the races of 1966 / 67 look quite unproblematic. But in 1968 the first F 5000 cars appeared, which were clearly beyond the F1 engine capacity limit. So I think, the races were officially opened to Formula 1 and Formula 5000 cars, but I don´t know whether they had COMBINED results only (= "Formula Libre" according to my definition above) or whether there were two separate classifictaions (which would mean that two titles would have to be declared at the end of the season, one for the "South African Formula 1 Champion" and the second one for the "South African F 5000 Champion)?
And I think around 1972 thing got additionally complicated by more and more F2 cars appearing also on the grids. So were the races "officially" opened to F2 as well, or did they only appear, because they automatically fell under F1 (or F5000) specifications?
Can anybody help to clarify this for me?
