Cadillac changes its Formula 1 car but continues to struggle with front-brake cooling.

Cadillac has enlarged its front-brake inlet and adjusted front-wing details during the season, including the endplate vane and footplate tunnel, but the changes have not resolved its main reliability weakness.

Valtteri Bottas still suffered a front-brake fire in Hungary despite Cadillac using its largest inlet design, forcing him to drive into a barrier to stop the car.
