Are there any major tracks that have gone through fewer modifications than Mosport? It's my understanding that it's gone virtually unchanged since the sixties. Is this true?

I got to thinking about this while watching the ALMS from there earlier this year.

There are a couple of earlier threads about unchanged circuits:

Unchanged circuits

Unchanged circuits

In the first of these there's a series of photos covering the (fairly minor) changes to Mosport.

I believe Mosport has had some changes. The "hump" on Andretti Straight has been leveled out.

I was curious about Mosport because I wondered if you could compare lap times over the years. My understanding is that the lap record is 1:05.823 (Marco Werner, Audi Sport North America R10 TDI, 2008, ALMS LMP1)

When you compare that with Mark Donohue's 1:14.100 from 1973 it shows pretty clearly the benefits of advanced aero and modern tire technology over brute horsepower (not that the 917/30 didn't have good aero for its day)

Do not forget, that if concerns put the effort put into the Audi, into Porsche with the intent of going faster, it would be faster and quicker.

Such comparisons are too often comparing apples to oranges.
