All cars are divided into several categories and types. In the factory registers, each model is assigned to a specific class. Comparison of machines is subject to strict criteria. The class of small cars includes cars with engine power up to 90 hp, the class of racing cars is distinguished by a speed limit of over 240 km / h. Executive class - these are luxury cars, soft and smooth on the go. Sports cars are recognizable by their characteristic exterior, sweeping lines of a low-sitting body and a revving engine.
Each car has a set of distinctive features. However, any model tends to lose its attractiveness over time. Then the manufacturer takes up the update. Comparison of cars that have already passed part of their resource with new models is usually not in favor of the first. In the automotive industry, there is such a thing as modification. This means that any car can be modified with a change in design and exterior, but the brand, class and category of the car will remain the same. Sometimes the modification is cardinal, the car after the alteration so changes itsform that is unrecognisable. In the case of deep changes, the car receives an additional name as a continuation of the main one, for example, Opel Cadet turbo, or Mercedes 220 cruise. The options are countless. It is the variety of modifications that makes it possible to regularly compare machines of different categories and choose the best options for further production.
Most often, a new car is created in three versions, the main difference between which is the shape of the body. This is a sedan, hatchback and estate car. The sedan is an all-metal body divided into three compartments: the engine compartment to accommodate the engine with related components and assemblies, then the cabin for the driver and passengers, and finally the luggage compartment. In passenger cars, the engine is always separated from the passenger compartment, the tightness of the partition is a prerequisite for the characteristics of the car. The trunk of the sedan is also insulated with a special partition.
The hatchback body design is somewhat different. The engine compartment, like that of a sedan, is hermetically separated from the passenger compartment, but the trunk is a continuation of the cabin space, there is no partition. The role of the partition is performed by the back of the rear seat, but the separation of the trunk and the passenger compartment in the hatchback body is purely conditional. From the back of the seat to the glass of the tailgate, a horizontal panel is installed made of pressed fiberboard, pasted over with densematter. The fundamental difference between a car with a hatchback body and other cars is a shortened rear overhang and, as a result, a reduced volume of the luggage compartment. The advantage of a hatchback is a large tailgate. With the door open, it is convenient to load any cargo.
Similar to hatchback characteristics has a station wagon, the body of which is designed in the same way. Comparison of cars with a hatchback body and a station wagon reveals a significant difference. The station wagon is much longer in the rear, which gives a significant gain in luggage space. The station wagon's rear door is more vertical, and this allows for an extensive view. On some models, the tailgate may be in a sloping position like a hatchback, but the car's rear overhang remains extended anyway.
This body type is called "liftback". However, this type of special distribution has not received due to the inconvenience when using the tailgate. Comparing cars by performance is the best way to determine the most successful designs. And if we apply in production the results that a comparison of cars by parameters can give, then in the near future new modern cars will appear that incorporate the best qualities of their predecessors.
