When it comes to a Formula 1 car’s packaging, an important factor is the sidepods. Their job is to make the car body and small and tight as possible while being big enough to house the manifolds and radiators. The engineering key here is the cold air intake to keep the radiator, Power Unit and essential components cool enough for high performance. Radiator inlets are used for this purpose with the main inlets positioned on each side of the car, carefully structured to let in the maximum amount of cold air while being as small as possible to reduce drag. For tracks where the air is hot, teams put a flare on the opening to help increase airflow intake.
