Car's safety is subdivided into active and passive safety. Speaking a dry and officially, active safety is a complex of car properties reducing a possibility of car accident occurrence.
Actually it is not so simple with active safety: many things depend on the driver, on his/her readiness to use car potential competently in a critical situation.
Active safety includes following components:
- reliability of units, packs and systems of the car - first of all it concerns a braking system, steerage… and further on the roll;
- car stability - its ability to move on the set trajectory, counteracting the forces causing its drift and overturning in various road conditions at high speeds;
- configuration of the car: front and rear engine position, çàäíåìîòîðíàÿ. Stability and readability of the car depend on configuration;
- Braking properties - no comments;
- hauling capacity (hauling dynamics) - car's ability to accelerate momentum intensively that influences driver's confidence while overtaking, passing crossroads, while getting out from emergencies when it is already late to slow down, but difficult conditions do not allow to maneuver;
- information capacity - a quality to provide the driver the necessary information. It can be internal (necessary for steering), external (directed on other participants of movement), additional (in conditions of a restricted view). Common examples: if car's design does not provide to the driver good view, if braking signals such, that the next car's driver can't notice them, if the car is not equipped by fog lights - in any case this car is dangerous; - driving comfort - no comments: if driver while driving the car quickly gets tired - this car is dangerous.
But if the crash was inevitable - this is the time of passive safety systems, directed on the person's safety at car accident. Passive safety is divided into external and internal. External safety defines car's safety for those around it - for example, in case of running into a pedestrian. It depends on many factors, the most obvious are - absence on a car' body of sharp projecting parts, height and a discharge angle of a windshield, presence of space between the engine and a cowl and so forth.
Internal safety is defined by the following factors:
- body design. Person's body load on quick slowdown at road accident and preservation of passenger compartment after body's deformation depend on it;
- safety belts. The idea to bind a person to the seat to rescue his/her life in an accident was born in 1907. Belts in the majority of cars are three-dot, inertial, in some sports cars are used also four-dot belts - to keep the driver better in the seat;
- air bags. They are placed not only in front of the driver, but also in front of the front passenger, and also from sides;
- seats with active headrests;
- safety details of passenger compartment's interior.
Now we will talk directly about Subaru cars safety. Actually, here is a clean slate that for a long time is recognized all over the world - Subaru cars not once received the maximum points in ratings of National Highway Traffic Safety Administration (NHTSA), Insurance Institute for Highway Safety, IIHS and their European colleagues.
Subaru Forester of the 2008 model year has received the highest point in crash-tests of Euro-NCAP for frontal impact and side crash.
Actually, comments needless.
