Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. The formula in the name refers to a set of rules to which all participants and cars must conform. Each year, the F1 World Championship is held. It consists of a series of races, known as Grands Prix, held usually on purpose-built circuits, and in a few cases on closed city streets. Drivers are awarded points based on their finishing position in each race, and the driver who accumulates the most points over each championship is crowned that year's World Drivers' Champion. As of the 2019 Abu Dhabi Grand Prix, there have been 774 Formula One drivers from 39 different nationalities who have raced at least one of the 1,018 FIA World Championship races since the first such event, the 1950 British Grand Prix. Seven-time champion Michael Schumacher holds the record for the most championships, while his 91 wins and 155 podium finishes are also records. Lewis Hamilton holds the record for the most pole positions with 88. Rubens Barrichello has entered more Grands Prix than anyone else - 326 times in total - as well as having made an unsurpassed 322 race starts. The United Kingdom is the most represented country, having produced 163 drivers. Nine countries have been represented by just one. Indonesia became the latest country to be represented by a driver when Rio Haryanto made his Formula One debut at the 2016 Australian Grand Prix driving for Manor Racing.
