Notes
1) One:1 smashed the boards lol
2) The only reason the P1 is that high is because you get a full boost bar every lap when your hotlapping.
3) The RUF CTR3 is a terrible hyper. In fact, it has a lot of times slower than the super class.
4) Ferrari 599XX is missing from the list because its online only and their are no online lap times

But if I was to guess, it would be between the Huayra and Lykan
5) Caterham SP was faster than every other super in pretty much every track. Pure dominance.
6) The VUHL is surprisingly quick
7) More people need to hotlap with the Mazzanti and especially the 650S. No reason for the 12C to be that much higher
8) Caterham superlight is much slower than I anticipated
I know some cars will be shifting slightly in the future and some others need for hotlappers to look at (650S) but this should give you a pretty good idea on what car to choose when racing online if you want the best chance of winning.
