What happened: Red Bull team principal Laurent Mekies confirmed the Milton Keynes outfit will take an engine penalty for Sunday's Brazilian Grand Prix. Head of strategy Hannah Schmitz noted adjustments were required following issues identified during Friday practice at Interlagos.

Why it matters: Verstappen sits second in the drivers' championship following his victory in Mexico, but only 16 points separate second and fifth place. With the title already decided, the grid drop complicates his defense of the runner-up position while other contenders also manage penalties.

What to watch: Qualifying and final preparations continue at Autodromo Jose Carlos Pace ahead of Sunday's race.
