Various systems for awarding championship points have been used since 1950. The current system, in place since 2010, awards the top ten cars points in the Drivers' and Constructors' Championships, with the winner receiving 25 points. If both cars of a team finish in the points, they both receive Constructors' Championship points. All points won at each race are added up, and the driver and constructor with the most points at the end of the season are crowned World Champions. Regardless of whether a driver stays with the same team throughout the season, or switches teams, all points earned by him count for the Drivers' Championship.
