Ferrari's Sebastian Vettel retained Mercedes at the top of the records with record time in final practice for the Brazilian Grand Prix, and Australian Daniel Ricciardo finished fifth in the row.
Germany, its Formula 1 champion hopes next season after Mercedes rival Lewis Hamilton won his fifth title in Mexico last month, on Saturday made the best lap of a minute of 07,948 seconds.
Vettel's time was about half a second faster than last year's pole position set by Mercedes & Valtteri Bottas at Interlagos.
Hamilton was 0.217 seconds slower, with Bottom third and Ferrari's Kimi Raikkonen fourth.
Two Red Bulls Max Verstapa and Dani Ricciardi, who had a five-time penalty after the turbo swap, were fifth and sixth in a row.
Ricciardo kicked off after his Red Bull team replaced the turbocharger on the car's power unit, exceeding the permitted driver's license.
Christian Horner, chief of staff, said the problem was the result of Ricciard's retirement on the previous race in Mexico and the use of the local marshal firefighters' apparatus.
Mercedes will reach fifth consecutive constructor championship race on Sunday, unless Ferrari scores 13 points more than them.
If that happens, Ferrari eleven will end up in a trick, and the battle will remain open until the final round in Abu Dhabi.
Hamilton missed a 15-minute session with mechanics working on his car after the smoke was visible coming from Mercedes's back.
A team spokeswoman said the exhaust pipe came in the fight and should have been restored to the ground until Hamilton could return.
