Following a discussion going on in the F1 crazy statistics topic, it is worth having an own topic regarding the following discussion:
During the course of history, F1 has remained (or came back) to certain venues. For example Monza, Red Bull Ring, Hockenheim, Spa, Silverstone, Hermanos Rodriguez and Monaco. Due to safety regulations, budget cuts, politics or simply modernizing the track facilities, all those tracks have had some sort of an overhaul.
But at what extend would one call a race at Spa nowadays as the same track as it was when Clark won? The main difference is the length was shortened by half. But the track is still located at the same place.
Same goes for Silverstone. After the 2010/2011 overhaul, is it the same track where Schumacher won at the same day Trulli had his major shunt at Bridge in 2004? A corner that doesnt exist anymore.
What about the two Kyalami victories by Mansell in 1985 and 1992? In between those victories the layout of the track was altered so much, that about 90% of the layout was changed.
So, in short: What classifies as "the same racing track" in cases like the above mentioned ones? What other examples do you know of? Circuits mentioned dont have to be limited to F1 only.
Kyalami as it was used from 1968 to 1988.
Kyalami as it was used from 1991 onwards.
The Silverstone track changes over the years.
The differences between Zandvoort over the course of two decades.
Edit: Some typo's.
