- Body-on-frame, also known as ladder frame construction, is a common motor vehicle construction method, whereby a separate body or coach is mounted on a strong and relatively rigid vehicle frame or chassis that carries the powertrain (the engine and drivetrain) and to which the wheels and their suspension, brakes, and steering are mounted. While this was the original method of building automobiles, body-on-frame construction is now used mainly for heavy trucks, pickups, and predominantly large SUVs. In the late 19th century the frames, like those of the carriages they replaced, might be made of wood (commonly ash), reinforced by steel flitch plates – but in the early 20th century steel ladder frames or chassis rapidly became standard. Mass production of all-metal bodies began with the Budd Company and the Dodge Brothers. Mass production of all-metal bodies became general in the 1920s but Europe, with exceptions, followed almost a decade later. Europe's custom-made or "coachbuilt" cars usually contained some wood framing or used aluminium alloy castings. Towards the beginning of international automobile assembly and construction, most manufacturers created rolling chassis consisting of a powertrain, suspension, steering column and a fuel tank that was then sent to a coachbuilder that added the body, interior and upholstery to the customers specific requests. In contrast, unibody or monocoque designs, where panels within the body supported the car on its suspension, were developed by European manufacturers in the late 1920s with Budd USA (which had a number of large factories in Europe) and its technical knowhow. Because of the high cost of designing and developing these structures and the high cost of specialised machinery to make the large pressings required by this style of construction it is not used by low-volume manufacturers, who might construct an equivalent by welding steel tube to form a suitable space frame.

- Un bastidor o chasis (que es parte de un chasis pero es más conocido como tal por su importancia en el chasis), es una estructura compuesta por largueros (vigas longitudinales) y travesaños (vigas transversales) a la que de una forma u otra se deben fijar todos los elementos y grupos mecánicos que conforman un automóvil, como el motor, los grupos de transmisiones, los ejes de carrocerías, etc. A partir de la década de 1950, el empleo del bastidor se ha limitado principalmente a los vehículos todo-terreno, camiones, camionetas grandes y algunas camionetas livianas, y se ha sustituido en la mayoría de los automóviles por carrocerías monocasco, en las que bastidor y carrocería quedan integrados en un única estructura (generalmente de acero), de la que no pueden separarse. Es importante recalcar que el bastidor (que forma parte del chasis) es totalmente independiente de la carrocería, aporta gran rigidez y soporta grandes esfuerzos sin que influya su alineación durante la marcha por las irregularidades del camino.

- La carrosserie sur châssis est une méthode traditionnelle de construction automobile. Le montage séparé de la carrosserie sur un châssis rigide qui prend en charge la transmission fut la méthode originale de construction d'automobiles, dont l'assemblage est encore employé. À l'origine, les châssis furent construits en bois (généralement de frène), mais ses assemblages en échelle d'acier devinrent communs dans les années 1930. Cette technique n'est pas comparable aux nouvelles carrosseries monocoque, et peu de véhicules modernes les utilisent encore outre les camions. (fr)
- 프레임 차체는 차체가 프레임과 나누어져 있는 자동차의 차체 구조를 말한다. 정식 명칭은 이다. 프레임 차체는 일본에서 유입된 잘못된 말이다. 반대는 모노코크 차체이다. 모노코크 차체보다 찌그러짐이 덜하지만, 충격을 차체 전체로 흡수시켜주기 때문에 모노코크 차체보다 오히려 더 위험하다. 스포츠 유틸리티 자동차와 트럭, 대형 차량에 주로 많이 쓰인다. 하지만 스포츠 유틸리티 자동차의 경우, 최근에는 프레임 차체가 잘 쓰이지 않는다. (ko)
- Rambygge kallas det när chassit och karossen är separat byggda på ett fordon. (sv)
