The Constructor Championship in Formula 1 is a measure of the performance of the ten teams in the F1 World Championship. Points are awarded to each team based on the positions of their cars in each race, and the team with the highest number of points at the end of the season wins the championship. Since the 1979 season, points from all cars entered by each constructor have counted towards their championship total. The Constructors Championship is won when it is no longer mathematically possible for another constructor to overtake another's points total regardless of the outcome of the remaining races, although it is not officially awarded until the FIA Prize Giving Ceremony held in various cities following the conclusion of the season. Ferrari holds the record for the highest number of World Constructors' Championships victories, having won the title on 16 occasions. The present system of Formula One World Championship points scoring was adopted in 2010, and the top 10 drivers at the end of each Grand Prix receive points based on the positions they finished, which contribute towards determining both the World Drivers’ and World Constructors’ Championships at the end of the season.
