TYPES OF A MOTOR CAR BODY
The main purpose of a motor car body is to provide comfortable accom-
modation for a driver and passengers. With the introduction of unitary con-
structions, the body has become the main structure onto which all other vehi-
cle elements are attached. Therefore, the body is both a load-bearing structure
and a comfortable location for the occupants. One can distinguish between
some body types of a motor car, such as saloon, estate, hatchback, coupe, con-
vertible, etc.
Saloon is a fully enclosed body with either two or four passenger doors. The
common shape of the saloon body is based on three ‘boxes’: the front box forms
the engine compartment, the centre section is the container for the occupants
and the rear box is a storage space, called a boot (trunk) for the luggage.
Estate (station wagon) has the roofline extended to the rear of the body to
enlarge floor area for the carriage of luggage or goods. The rear door enables
bulky or long objects to be loaded easily. Stronger suspension springs are fitted
in the rear to support the extra load.

The hatchback design is usually based on a saloon body but with the boot
or trunk area blended into the centre section of the body therefore the hatch-
back is halfway between a saloon and an estate car.
Coupe is usually two-door type intended for two people: a driver and one
passenger. Some coupe models are designed ‘2 + 2’ but the back area is more
suitable for children or for occasional adult use.
Convertible, also called cabriolet or drop-head coupe, can be changed into
an open car by either removing a rigid roof or lowering a collapsible fabric roof.
The majority of mass-produced cars have a pressed steel body, although
aluminium bodies are being used increasingly due to their lighter weight. An-
other common practice is to mould body panels from GRP (glass-reinforced
plastics, often referred to as fibreglass). Other materials are also now used, such
as carbon fibre, to produce body panels and structures.
