Red Bull's Daniel Ricciardo and Pierre Gasly and Brendon Hartley of sister team Toro Rosso will all take 10-place grid penalties at the Brazilian GP as Renault's end of season woes continue.
All three have taken a new MGU-H for Friday practice, and since for all three that represents the first time this year their cars have taken an eighth element, they lose 10 places each.
Ricciardo has also taken a new energy store and control electronics, but since they are both his fourth examples, there are no penalties associated with the changes.
It's likely that all three drivers will incur further penalties if they take further new elements on Saturday, with Renault trying to minimise mileage.
During FP1 Brendon Hartley stopped on track with a cloud of smoke coming from the rear of the car after completing just two laps, suggesting that he will require more fresh engine components.
Christian Horner told Autosport that Red Bull believes Max Verstappen won't have to take any more penalties this year.
