Disclosed embodiments include airflow systems, vehicles, and controllers of airflow units. An illustrative airflow system of a vehicle includes an airflow inlet duct, an airflow intake duct, an air intake door, and an airflow unit. The airflow inlet duct is adapted to draw ambient air. The airflow intake duct is adapted to receive airflow from the airflow inlet duct. The air intake door is positioned therebetween. The airflow unit includes a controller configured to close the air intake door and seal off the air intake duct from the airflow inlet duct in response to receipt of at least one signal indicating at least one condition chosen from 1) a presence of water in the airflow inlet duct, 2) a hood of the vehicle being in an open condition, 3) a presence of rain received from a precipitation sensor, and 4) activation of a predetermined speed setting of a windshield wiper.

A motor vehicle front section of a motor vehicle includes a first spatial region, a second spatial region formed separately from the first spatial region, a first cover that covers the first spatial region, and a second cover that covers the second spatial region. The first cover extends substantially over a width of the motor vehicle front section, and the second cover extends substantially over the width of the motor vehicle front section. The first cover is arranged in front of or behind the second cover in a vehicle longitudinal direction. An access is provided in at least one of the covers for at least one connection arranged underneath the cover.

A vehicle front structure includes a dash upper panel and a grille top face portion having outside air introduction holes taking in outside air. The vehicle front structure includes a cover member covering an engine from a vehicle upper side and having a top plate rear portion opposed to the grille top face portion on a vehicle lower side throughout a predetermined range, including the outside air introduction holes, in a vehicle width direction, and a grille front face portion disposed from the grille top face portion to the top plate rear portion on a vehicle front side of the outside air introduction holes. The top plate rear portion has a shape having inclined surfaces extending from a vehicle lower side of the outside air introduction holes in the vehicle width direction, the inclined surfaces being gradually inclined to the vehicle lower side toward vehicle-width-direction outer sides.

In one aspect of the present disclosure, a barrier is disclosed that is configured for connection to a vehicle dash assembly including an HVAC opening defined by a flange. The barrier includes a body that is configured to obstruct a flow of suds into the HVAC opening, and at least one clip that is supported on the body. The body includes open upper and rear portions to allow for continued airflow through the HVAC opening, and the at least one clip includes first and second clip members defining a receiving space therebetween that is configured to receive the flange such that the first and second clip members are positioned on opposite sides of the flange.

A car having a water box comprising an outer face, an inner face, an air inlet opening, an air outlet opening and a water outlet opening. The inner face forms a water separating space that is connected to the air inlet and outlet openings and the water outlet opening. The water outlet opening discharges water out of the separating space. An air conditioner is connected to the air outlet opening to feed air from the water box into the air conditioner. An air feeding unit sucks the air into the air conditioner via the air inlet opening. The air feeding unit is designed as a suction fan. The water box comprises a wall that comprises fibers forming a non-woven fabric i.e. felt.
