Points are awarded to the top twenty-five classified drivers, and the top drivers who are able to achieve the Pole Position or the Fastest Lap during the qualify session are awarded with corresponding +3 and +2 bonus points.

The Season Championship will recognize only each driver's best 18 of 21 race results including all bonus points earned.^[19]

Points are awarded using the following system:

Guest drivers are ineligible to score points.

If a guest driver finishes in first position, the second-placed finisher will receive 50 points. The same goes for every other points scoring position. Thus, if three guest drivers place fourth, fifth and sixth, the seventh-placed finisher will receive 34 points and so forth – until the twenty-eighth-placed finisher receives the final point.
