Cars will be run in heats of two cars each.
The cars are to be launched with their front wheels on the starting line. The first car to have its front wheels cross the finish line is the winner. If neither car makes it to the finish line, the car going the furthest in its lane wins.
If the wheels of a car should cross over the lane marker the car shall be disqualified. The competing car immediately becomes the winner.
Winning cars will advance to the next round until all are eliminated except one car.
