A vehicle airflow system includes a centrifugal fan 18 and an air diffuser 38. The centrifugal fan is configured to direct air radially outward from a rotational axis of the fan. The air diffuser 44 has a plurality of air deflectors that are disposed radially about the fan. The air deflectors have curved surfaces 52. Each curved surface defines an airflow channel 54 that has an inlet 56 extendingradially outward from a periphery of the centrifugal fan and an outlet 58 extending axially away from the diffuser relative to the rotational axis of the fan.
