2.3.1 Classification of Cars
In order to make it easier for the end consumer to understand what kind of car/cars a particular manufacturing plant produces, they divided all cars into classes. After the introduction of the car classification, everything fell into place. A person who wanted to buy a passenger vehicle could, without deriving complex formulas of his wishes and preferences, decide what class of car he needed. Each class has some generalizing characteristics that partly describe the functional purpose of the car.
The official standardized classification is complex. It is used exclusively in regulatory documents. The system of the unofficial European classification of passenger cars (Table 1), which is often used by journalists from various specialized media, is one of the easiest to understand.
Due to the fact that the size of cars has increased over time, in order to please consumers, certain models that were placed by manufacturers in a certain class, in fact, started belonging to a higher class. Therefore, arose the necessity to expand the classification framework. The designations remained the same, but with the addition of the "+" symbol (the differences are shown in table 2).
