Formula One's feeder series has been rebranded by the FIA and new owners Liberty Media.
GP2, a championship which has been won by Lewis Hamilton, Nico Rosberg and more recently Jolyon Palmer, will be known as Formula Two with immediate effect following a meeting of the World Motor Sport Council in Geneva on Thursday.
Formula Two will support the Formula One world championship with 11 rounds starting at the Bahrain Grand Prix on April 16 and ending in Abu Dhabi. There will be an additional race in Jerez which is not on the F1 calendar.
"Completing this process with Formula One Group and bringing FIA Formula 2 to life is a very important step," FIA president Jean Todt said.
"The championship will provide the final level for junior drivers who are looking to reach the ultimate goal of Formula One, and we have achieved a key target for the FIA in completing our single-seater pyramid."
