Tube Frame

Also known as Superleggera.

A method of vehicle construction, using a network of thin metal tubes welded together as a full-body frame. The frame is then covered with lightweight materials such as aluminium. Although this method was widely used for production sports cars in the 1930s to 1960s (for example, Aston Martin DB5 and most Ferraris), it is now only found in low-volume and hand-built sports models.
