One day of flat-out racing: four qualifying heats with reshuffled groups, two pre-finals, and a twelve-driver Final — run across two layouts of the circuit.
The same track, raced two ways. Heats 1 & 3 and the Final run Normal; Heats 2 & 4 and both Pre-Finals run Reverse.
Every driver races all four heats with the groups (10–12 each) reshuffled every time. Combined heat points set the overall standings, which are then split by seeding — odd positions (P1, P3, P5…) go to Pre-Final 1 and even positions (P2, P4, P6…) to Pre-Final 2. The top 12 of the overall standings after the pre-finals form the Final.
Timings are subject to the final number of registered drivers (40–50).
