A ventilation system for a vehicle can include a roll over protection system. The roll over protection system can include a bar. The ventilation system can have an air duct configured to selectively attach to and detach from the bar.

A cooling air feeding apparatus is for a motor vehicle, which has a motor vehicle body and a drive train, the drive train being assigned a cooler, and at least the cooler being arranged in a rear region of the motor vehicle body. The cooling air feeding apparatus has a throughflow opening, which is in the rear region and which is configured to receive air from surroundings of the motor vehicle and to feed the received air to the cooler. In order to regulate a driving state of the motor vehicle, the throughflow opening is configured with a variable throughflow cross section with the aid of a closing element, which is assigned to the cooling air feeding apparatus. The throughflow opening is configured to be controllably closed individually completely or partially and to be opened completely.

An apparatus allows for the distribution of air over a wider range of area. That apparatus includes a telescoping duct assembly, having an inner duct section received for sliding movement in an outer duct section, a receiver in the inner duct section, an elongated port in the outer duct section and an air register held in the receiver and projecting through the elongated port.

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 ram air vent for a vehicle has a base defining a base aperture therein; a hood connected to the base over the base aperture, the hood and base defining a forwardly facing air inlet therebetween, the hood and the base defining an air passage extending from the air inlet to the base aperture; a baffle disposed in the air passage for deflecting air flowing in the air passage from the air inlet for separating water from air flowing in the air passage, the baffle facing the air inlet; and at least one water passage defined in at least one of the base or the hood. The at least one water passage exits a rear side of the ram air vent. The at least one water passage drains water separated from air flowing in the air passage from the ram air vent.
