Late power unit change reshuffles United States GP grid with pit lane start confirmed

Lance Stroll will start the United States Grand Prix from the pit lane after Aston Martin opted to change the power unit in the back of his AMR26.

Stroll was due to start P16 at the Circuit of the Americas, and his removal from the grid elevates both Williams drivers, both Cadillacs and Franco Colapinto and Gabriel Bortoleto, both of whom have also taken power-unit grid penalties.
