In one of the biggest changes to the sport's weekend schedule, drivers will race on both Saturday and the showpiece event on Sunday, with qualifying on Friday.
What is the F1 sprint?
It is a race, with any tyre allowed, on Saturday afternoon over 100km, which is 17 laps of Silverstone and around a third of a normal grand prix.
The top three drivers will be awarded points; three for the winner, two for second place and one for third. There is also no need to pit stop.
Qualifying will decide the sprint starting grid, with the final order of the sprint race then making up the grand prix positions.
Any other changes?
Due to the sprint race, there is just two practice sessions rather than the usual three.
Qualifying to moved forward to Friday evening, with only soft tyres allowed.

FP2 is on Saturday, July 17, at 12pm, with the sprint race for around half an hour from 4.30pm BST.
