P1racenews AI automatic summary:
There will only be 16 cars on the grid in Austin with four drivers in the pit-lane.
All four drivers from Haas and Aston Martin, Kevin Magnussen, Nico Hulkenberg, Lance Stroll, and Fernando Alonso, will start from the pit lane at the United States Grand Prix. This is due to changes in parts and set-up to their cars. These changes were made as both teams brought significant upgrades to the Circuit of the Americas, but had limited practice time to fully understand and gain knowledge of the new parts. The parc fermé conditions, which restrict major changes to the cars after a certain point, kicked in after just 60 minutes of practice on Friday. Magnussen and Hulkenberg have different rear wing assemblies, while Stroll and Alonso will use different floor specifications. This will result in pit-lane starts for these drivers, leaving 16 cars on the grid.
