P1racenews AI automatic summary:
Liam Lawson is replacing Daniel Ricciardo for the remaining six F1 races this season.
Liam Lawson will start the United States Grand Prix from the back of the grid due to a power unit change. He replaced Daniel Ricciardo as the Red Bull junior driver for the rest of the F1 season, starting at Circuit of the Americas. Only the exhaust system in Lawson’s new power unit is within the legal limit, with other components exceeding their allocation. The grid penalty for the upcoming race will not affect the sprint event. Red Bull’s advisor, Dr. Helmut Marko, had announced the engine change earlier; the FIA has now confirmed it. Lawson finished P13 in practice, showing promising performance as he aims to secure a full-time seat in the future, potentially replacing Sergio Perez.
