A vehicle body of a vehicle with a rear engine includes a rear structure that defines a receiving space for the rear engine; an assembly support connected to the rear structure and having at least one recess for passage of air; an air-guiding device mounted on the assembly support and having a retractable and extendable upper part and additionally having a fixed lower part with at least one recess for the passage of air; and a protective grille inserted into the respective recess of the lower part of the air-guiding device. The protective grille is assigned a covering element that is configured to be shiftable relative to the protective grille in order to open up or to close openings defined by the protective grille.

A vehicle includes a first wall defining a portion of a cargo bed of the vehicle. The first wall has an opening. The vehicle also includes at least one duct having a first opening, a second opening, and an airflow passage extending between the first and second openings. The at least one duct first opening is in fluid communication with the opening in the first wall. An airflow regulation mechanism is operably coupled to the at least one duct first opening and is configured to enable control of an air flow into the at least one duct first opening.

A ventilation device for cooling a passenger compartment of a vehicle includes a blower module that is operationally coupled to an electrical circuit of a vehicle. A first duct assembly and a second duct assembly are coupled to the vehicle. The first duct assembly extends between a passenger compartment and at least one of a trunk and an opening in an exterior surface of the vehicle. The second duct assembly extends between the passenger compartment and an aperture in the exterior surface of the vehicle. At least one of the first duct assembly and the second duct assembly are operationally coupled to the blower module. The blower module is configured to exchange air in the passenger compartment with air from an ambient environment in which the vehicle is positioned to cool the passenger compartment.

A rear wall structure of a passenger compartment includes a vent opening and a horizontally extending seal protruding in a vehicle forward direction. A trim panel has a rear surface facing the rear wall structure. A vertically extending seal extends from the rear surface. With the trim panel installed to the rear wall structure the vertically extending seal contacts the rear wall structure, and, the horizontally extending seal of the rear wall structure contacts the rear surface of the trim panel such that the rear surface and the vertically extending seal of the trim panel and the upright interior surface and the horizontally extending seal of the rear wall structure define an air outlet passageway that extends from an opening in the trim panel to the vent opening.

A vehicle passenger compartment vent structure that includes a rear wall structure, a drafter vent assembly, a baffle and a trim panel. The rear wall structure defines a rearward area of a passenger compartment of a vehicle. The rear wall structure defines at least one vent opening. The drafter vent assembly is installed to the rear wall structure covering the at least one vent opening. The baffle is installed to the rear wall structure adjacent to the drafter vent assembly and is configured to dampen sound from the drafter vent assembly. The trim panel is installed to the rear wall structure contacting the baffle and concealing the drafter vent assembly.

An assembly for acoustically insulating a cabin of a vehicle includes at least one air exchange port and a functional component. The air exchange port is configured in an outer panel of the vehicle for exchanging air between the cabin and a surrounding area of the vehicle. The functional component includes an acoustically insulating surface such that a portion of the functional component is detachably attached to the outer panel and the functional component is positioned proximal to the air exchange port. The acoustically insulating surface of the functional component and the outer panel define an airflow passage between the at least one air exchange port and the cabin.

A vehicle body includes a cabin portion, a bed portion, and an air extractor. The cabin portion defines a passenger cabin and includes a hollow pillar having an opening to the passenger cabin. The bed portion defines a bed and includes a hollow frame rail elongated from the pillar. The pillar and the frame rail define an airflow path from the opening. The air extractor is positioned in the frame rail and is in communication with the airflow path and an ambient environment.
