What happened: Sergio Perez expressed disappointment with his team's performance at a circuit he previously called their last chance for a strong showing. He noted that Cadillac expected a better result on a track where engine power is less critical.

Why it matters: The result highlights the development gap between Cadillac and established midfield competitors. Perez pointed to Aston Martin and Williams as teams that have made significant strides, leaving Cadillac struggling for pace.

What to watch: Cadillac will start at the back of the grid for Sunday's race at Marina Bay Street Circuit.
