Car classes in FM6

i’d like to know how are the cars grouped or organised, are they grouped into classes according to their overall performance level or is some criteria used?

What ManteoMax said. The FM6 classes and corresponding PI ranges are below:E 100-300D 301-400C 401-500B 501-600A 601-700S 701-800R 801-900P 901-998X 999

Can someone explain to me the different classes in FM 6 please? I see the designation, just don’t understand the meeting. I am mostly interested in race cars/

Hi deelee, I merged your thread with a previous similar question.
