Red Bull reportedly believe they know where weak spots in Mercedes’ power units may be, which would cause power losses as mileage increases. 

After Max Verstappen took a fresh engine in Russia that caused an engine penalty, along with Valtteri Bottas, there is increased focus on when or whether World Championship leader Lewis Hamilton will follow suit.

The Honda and Mercedes power units have appeared to be relatively evenly matched this season, but while Red Bull’s appeal against a “trick” in the Mercedes engine was discarded by the FIA, they have supposedly identified where the Silver Arrows may lose out moving forward.
