Sprint qualifying has three sessions, where the five slowest cars are eliminated from the first two – like normal qualifying.
These sessions, known as SQ1, SQ2 and SQ3, last 12, 10 and eight minutes respectively.
This will make up the grid for the sprint race, which is 100km.
The top eight finishers score points, from eight for first place to one for eighth spot, which will get added to the overall drivers’ championship standings.
After Austin, the final two sprint events of the season take place in Brazil and Qatar.
