There are two classes eligible for the points championship:
The "A" class is for chassis built in 1995 and newer
The "B" class is for chassis built in 1994 and older
The date of manufacture is for the individual car, not the model. If a prototype of your car was built prior to 1994 but wasn't released in production until post January 1, 1995, you are Class "A". It is the responsibility of the car owner/driver to consult the CASC-OR Road Race, General Competition and Formula 1600 Regulations to ensure their vehicle meets the class specifications.
