The Championship is a competitive mode which divides players into groups of 15 people.
The goal is to move from one Stage to another until you reach the last Stage and win the World Championship. At certain stages, players can also unlock new parts for their cars.
One Championship round lasts 48 hours. At the end of the round, top players from the group move into the next stage. The exact number of people depends on the group's actual size. For example, if the group is full and there are 15 players, top 6 move into the next Stage.
In order to get to the top, you need to defeat as many groupmates as possible. When you defeat an opponent's car, you get a medal. You can lose your medals if the players you defeated upgrade their car and win the fight against you.
It is also possible to try Big Fight in order to fight all the players in the current stage and be instantly promoted.
