Fernando Alonso will join George Russell and Sebastian Vettel at the back of the grid for the United States Grand Prix following the latest power unit change.
Alonso has taken a completely new system in his Alpine - internal combustion engine [ICE], turbocharger, MGU-H, MGU-K and energy store, as well as a ninth exhaust this year, with only eight allowed for a season.
The decision taken by the team follows moves by Aston Martin and Williams for four-time F1 champion Vettel and British driver Russell.
The power units inside the cars of Vettel and Russell have taken a new ICE, MGU-H and turbocharger.
The grid slots from 18th to 20th for the three drivers will be determined by how they perform in qualifying.
Valtteri Bottas also serves a grid penalty, but only drops five places for taking a new ICE in his Mercedes, his sixth of the campaign.
