The HFO Competition features classic Grand Prix racing cars from the 20 year period between 1966 and 1985. Obviously there are great differences in power and handling between the more senior and the more junior cars and so they are divided into 4 classes:
Class A — 1966-1971 Formula One cars.
Class B — Post-1971 non-ground effect Formula One cars.
Class C — Post-1971 ground effect Formula One cars.
Class D — Post-1971 flat bottom Formula One cars.
Effectively, there are 4 competitions going on within every race and each provides points for the driver based on his/her placing in the car’s class and the number of competing cars in that class.
An additional point will be awarded to the drivers who achieve the fastest lap in each class during the race.
