Max Verstappen will take a five-place grid penalty for an engine change for Sunday's Brazilian Grand Prix, as he moves on to his sixth internal combustion engine of the 2024 Formula 1 season.
The championship leader had already taken a new ICE beyond the allowable limit of four at July's Belgian Grand Prix at Spa-Francorchamps, this being the third successive year that Red Bull had chosen to take the hit at that circuit.
Following a series of power unit issues in Mexico's Friday sessions, as an air leak kept Verstappen confined to the garage during the final part of FP1 and the majority of FP2, Red Bull has chosen to take another engine from outside its pool.
This means that Verstappen will lose five places from wherever he qualifies for Sunday's grand prix, although his sprint race qualifying result will be unaffected.
Verstappen will also use a new exhaust system, taking him up to eight used throughout the season, with eight permitted through the year.
The Dutchman has been in an increasingly precarious situation with his engine allowance for much of the season, as a problem with one unit in practice for the Canadian Grand Prix in June led to a lengthy inspection - leading to a fourth ICE being used as early as Spain.
This led to Red Bull taking a new Honda powerplant at Spa, but Verstappen has now lost another from his pool as a result of the issues in Mexico.
Red Bull adviser Helmut Marko told Austrian broadcaster ORF that the engine eventually used at the Autodromo Hermanos Rodriguez "was no longer intended for the race, and the older an engine gets, the more its performance diminishes."
He added that the Red Bull was giving up approximately "three to eight km/h on the straights" thanks to the reduction in horsepower.
Asked on Thursday if Brazil was one of the less compromising races to take a power unit penalty, Verstappen responded that it was not a certainty that he could recover ground lost to a penalty.
"That is something that is always unknown. You think that one particular track is the best place to take an engine or whatever penalty, but it's never guaranteed. But yeah, it's a possibility."
