Please bare in mind that many vehicles are missing, but I've collected as many as I could. If anybody has any not already my list, please share!
The scores are based on the overall test performance done by the vehicle in the supertest: slalom; 'Ring; Hockenheim; Evasive; etc
What should be known is that there are two overall rankings": there is a ranking out of 70 points and that ranking populates most of the list and a ranking out of 80 points. The latter was recently added when Sport Auto decided to include this water course in there superests.
So, the older vehicles have never been tested on the wet handling course (Carrera GT, Gallardo and etc)
Sport Auto lists both scores in their new tests, one without the the wet handling course and one with. Example, picture below. Score on left is with WHC
