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.
