What happened: Ferrari is making a planned engine change on both Lewis Hamilton's and Charles Leclerc's SF-26, costing each a 10-place grid penalty at Interlagos. Max Verstappen also serves a grid penalty for engine changes. The decision follows a tough set of Friday practice sessions for Ferrari, per Autosport.

Why it matters: Ferrari trails Mercedes by 126 points, and the penalties push both its drivers down the order days after Hamilton pressed the team for changes following his lap-one clash with Leclerc in Mexico City. Starting deep in the field limits both cars' points potential in Brazil.

What to watch: Qualifying at Interlagos sets the order before the penalties are applied.
