The reduction in races comes as the European Grand Prix, where GP2 runs as a support race, will be dropped.
A round is slated to take place at the Nurburgring on the weekend of 6th-7th July, when F1′s yet-to-be-confirmed German Grand Prix is set to take place.
GP2 will support 11 rounds on the 2013 F1 calendar. Unlike last year there will be no standalone double-header in Bahrain, though the series will race there during the F1 race weekend.
The restoration of the Abu Dhabi races means there is a six-week gap between the Singapore double-header and the final two races at Yas Marina Circuit.
An Abu Dhabi round was last part of the GP2 calendar in 2010. A one-off ‘GP2 Final’ was held at the track in 2011.
Pre-season testing will take place at Jerez and the Circuit de Catalunya in February and March respectively.
