Convertible

A convertible or cabriolet (/ˌkæbriˈl/) is a passenger car that can be driven with or without a roof in place. The methods of retracting and storing the roof vary among eras and manufacturers.

For other uses, see Convertible (disambiguation).

A convertible car's design allows an open-air driving experience, with the ability to provide a roof when required. A potential drawback of convertibles is their reduced structural rigidity (requiring significant engineering and modification to counteract the effects of removing a car's roof).[2][3]


The majority of convertible roofs are of a folding construction framework with the actual top made from cloth or other fabric. Other types of convertible roofs include retractable hardtops (often constructed from metal or plastic) and detachable hardtops (where a metal or plastic roof is manually removed and often stored in the trunk).

Terminology[edit]

Other terms for convertibles include cabriolet, cabrio, drop top, drophead coupé, open two-seater, open top, rag top, soft top, spider, and spyder. Consistency is rare about the current use of cabriolet in preference to convertible.[4] The term cabriolet originated from a carriage cabriolet: "a light, two-wheeled, one-horse carriage with a folding top, capable of seating two persons"; however, the term is also used to describe other convertibles.[5]


In the United Kingdom, the historical term for a two-door convertible is drophead coupé, and a four-door convertible was called an all-weather tourer.[6]

Early convertibles used cotton woven so tightly that it was waterproof. Automakers had problems in securing raw materials to fulfill orders after World War II, including canvas in various shades for convertible tops, therefore limiting their manufacture.[36]
