Car model

An automobile model (or car model or model of car, and typically abbreviated to just "model") is a particular brand of vehicle sold under a marque by a manufacturer, usually within a range of models, usually of different sizes or capabilities. From an engineering point of view, a particular car model is usually defined and/or constrained by the use of a particular car chassis/bodywork combination or the same monocoque, although sometimes this is not the case, and the model represents a marketing segment.

A model may also be referred to as a nameplate, specifically when referring to the product from the point of view of the manufacturer, especially a model over time. For example, the Chevrolet Suburban is the oldest automobile nameplate in continuous production, dating to 1934 (1935 model year), while the Chrysler New Yorker was (until its demise in 1996) the oldest North American car nameplate. "Nameplate" is also sometimes used more loosely, however, to refer to a brand or division of larger company (e.g., GMC), rather than a specific model.

This engineering frame may have derivatives, giving rise to more than one body style for a particular car model. For example, the same model can be offered as a four-door sedan (saloon), a two-door coupé, a station wagon (estate), or even as a folding-roof convertible, all derived from essentially the same engineering frame. An example of this is the BMW 3-series.

Fully specifying an automobile can involve many levels of detail, most basically: manufacturer (company), model (brand, product name), and model year. Often, these further details are included: body style (e.g., 2-door, 4-door), trim level (often denoted by lettering after the model name), and individual options (e.g., a sunroof). In North America, formal reference to automobiles (e.g., in police reports) specify "year, make, model", i.e., model year, manufacturer, and product, as in a "2000 Toyota Camry."

The same car model can be offered with different mechanical internals, such as a choice of several engine sizes, automatic or manual transmissions, different suspension, braking or steering systems, etc.; all of these options considered fairly interchangeable on that specific body frame. It is common for any specific car model to carry additional badges or letterings to announce the mechanical option(s) incorporated on it.
