What happened: Ferrari drivers Lewis Hamilton and Charles Leclerc will each serve 10-place grid penalties at the São Paulo Grand Prix. The penalties follow Ferrari fitting new internal combustion engines to both cars, exceeding the season allocation of four power units.

Why it matters: The penalties hinder Ferrari in the constructors' championship, where the team trails Mercedes by 126 points entering Brazil. The setback comes after Hamilton called for Ferrari changes after a lap-one clash with Leclerc in Mexico City.

What to watch: Both drivers will look to recover ground at Autódromo José Carlos Pace after qualifying sets the preliminary grid.
