The previous format, consisting of a 30-minute qualifying session followed by the Super Pole that was contested by the top ten of the 30-minute session, will be replaced by the so-called shoot-out. The first 14-minute leg of the new qualifying session will be contested by the full 20-car field.
The 14 quickest qualify for the second leg while the six slowest cars have to enter the Parc Fermé. They will be 15th to 20th on the grid, according to the lap times they set. Following a seven-minute break, the 14 quickest will go out for their next efforts. This time, they have got just ten minutes to secure a top-eight position.
Those who don’t make it will be ninth to 13th on the grid. Following another seven-minute break, the top eight will battle it out for the pole position, with the quickest securing pole, the second qualifying for second grid position and so on. In every leg, the drivers may complete as many laps as they wish to do. The lap times set count only for the respective leg. The tyre sets for the qualifying are limited to five. Refuelling is allowed only following the first leg.
The drivers have to run approximately 160 kms with a standing start (2 p.m.) and two compulsory pit stops (re-fuelling and tyre change). The first compulsory pit stop may not be made before lap six.
Pit lane speed limit: Maximum 80 km/h (60 at the Norisring and in Zandvoort,).
