D1GP COMPETITION FORMAT

D1GP competitions are judged based on line, angle, speed, and style. Line involves taking the correct line, which is determined in advance by the judges. Angle refers to the angle of the car while drifting, and speed refers to the speed of the car when entering, going through and exiting a corner, whereby the less reduction in speed there is, the better. Drivers are also judged on how close the cars are at pre-determined points of the course (called “clipping point”), how close the car is to the wall, the amount of smoke, engine noise and various other factors.

Tanso (solo run)

    In tanso, drivers drift one at a time, judged individually and awarded points. Generally, each driver is allowed 2 runs, and the higher score from both runs is applied to the final ranking. Drivers are judged based on skill and in addition to observing the line, factors such as angle, speed and style are taken into account. Large point deductions are given when drivers cause the cars to spin or driver through the corners with under steer.

    Tanso also acts as the qualifying stage for the tsuiso (tandem run) competition, and only the top ranked drivers in the tanso competition are able to advance to the tsuiso round.

   
Tsuiso (tandem run)

    In tsuiso, 2 cars drift side by side. One car starts first (lead car) followed immediately by the other car (trailing car). The lead car driver drives to his/her best ability and the trailing car tries to mirror the lead car. If the trailing car manages to keep up with the lead car, comes as close as possible to the lead car and gets inside the lead car at a corner, the trailing car wins and is awarded an advantage. If the trailing car fails to keep up with the lead car, the lead car is awarded the advantage.
    Points are deducted for spins, under steering, if the drift angle of one car is shallower than that of the other car, and if control of the car becomes erratic. Therefore, the lead car driver may drift at larger angles, even at the cost of sacrificed speed. Accordingly, it is not necessarily the case that faster cars or higher powered cars will win. Note that tracing the set course line does not influence judgments as severely as in the TANSO stage. However, points are deducted from the lead car driver if his/her line through a corner hugs the inside thereof, such that the trailing car has no space to get inside.

    The same 2 cars compete in 2 heats. During the second heat, the lead car switches to become the trailing car, and vice-versa and the same competition is repeated. In the tsuiso tournament, drivers are judged in such a way that the points awarded to driver during each heat adds up to 10, for example “5:5” (i.e. both drivers collect 5 points each), or “7:3” (i.e. one driver is awarded 7 points while the other is given 3 points). The points after both heats are added up, and in the event that both drivers achieve the same number of points, or if the point difference is very small, the tournament enters into sudden death stage. In the case that repeated sudden death stage heats do not result in a win/loss, the judges will determine a winner by considering all factors as a whole. The maximum number of sudden death heats is 3.

    The top 16 drivers advance to the final stage of the tsuiso tournament, and the best 16 are reduced to 8, and then 4 and to the 2 finalists in a tournament format. Drivers are paired in such a way that the 1st placed driver is paired with the 16th placed driver in the tanso tournament, 2nd placed is paired with 15th placed, 3rd placed is paired with 14th placed etc,
