Trunk

[NANO]

The Trunk , boot , dickie  or compartment of a car is the vehicle's main storage compartment.The trunk or luggage compartment is most often located at the rear of the vehicle. Early designs included an exterior rack mounted on the rear of the vehicle to which it was possible to attach a real luggage trunk.Later designs integrated the storage area into the vehicle's body and evolved to provide a streamlined appearance.The main storage compartment is normally provided at the end of the vehicle opposite to which the engine is located. Some mid-engined or electric cars have luggage compartments both in the front and in the rear of the vehicle.Examples include the Volkswagen Type 3, Porsche 914, Porsche Boxster, Toyota MR2, and Tesla Model S. The mid-engined Fiat X1/9 also has two storage compartments, although the rear one is small, easily accessible, and practically cuboid in shape.Rear-engined cars have the trunk situated in front of the passenger compartment.Sometimes during the design life of the vehicle the lid may be restyled to increase the size or improve the practicality and usefulness of the trunk's shape. Examples of this include the Beetle redesign to the 1970s 'Super Beetle' and the pre-war and 1950s post war Citroën Traction Avant.The door or opening of a cargo area may be hinged at the top, side, or bottom. If the door is hinged at the bottom it is termed a tailgate, particularly in the United States. They are used on station wagons and pickup trucks, as well as on some sport utility vehicles . Traditional drop-down station wagon and pickup tailgates can also serve as a mount for a workbench.Traditional U.S. station wagons included a roll down window retracting into the tailgate to load small items or to allow the tailgate to be opened down on its bottom mounted hinges. Because of the potential for carbon-monoxide fumes, the tailgate window on station wagons should be closed whenever the engine is running.Two-way station wagon tailgates may be hinged at the side and the bottom so they can be opened sideways like a regular door, or drop downwards as load platform extenders.They are designed with special handle for opening in the selected direction on special hinges after the window is lowered.A three-way design that was also used by Ford allows for the tailgate to be opened like a door with the window up.General Motors developed a clam shell style "disappearing" design where the rear window rolls up into the roof and the tailgate slides down and beneath the load floor.If the door is hinged at the top it is termed a hatch, and is used on a hatchback.A bottom opening door is now common on sport utility vehicles.
