Test extremes of heat and cold

Vehicles made many millions of Euros invested in the development and preparation of its new models before being marketed. Much effort over years of development and tests, as there is much money at stake, besides the image of the brand and the success or failure.

Calor extremo ArizonaAny parameter can reach the success or failure of a vehicle, therefore, tests are many and complicated normally divided into phases. We must analyze the behavior and strength of each and every one of the elements of the new vehicle.

These tests are carried out on roads, speed circuits, test tracks and specific facilities. Today we will focus on the extreme tests, specifically in cold and extreme heat.

Actually there are many inhabited places where there really extreme conditions, since human beings tend to live in areas with nice weather. But brands must test the behavior of the car at 50 and -50. Therefore, Brands prove optimal conditions to fry an egg on the car hood and conditions under which you dump a glass of water and it freezes before reaching the ground.

Calor extremoFor this, deserts and very hot, dry areas, and near the polar caps will usually be chosen. Do you do an idea of ​​the places you could choose brands?

For tests of extreme heat, the most popular places are the Test Track Arizona Desert (EE.UU.), Death Valley in California (EE.UU.), o Ayers Rock (Australia), where ambient temperatures reach 50 ° C in the shade, if you find.

High temperatures greatly influence a car, since much items require a more or less stable temperature, or at least not very radical, to function properly.

Unlike cold, heat is common in most countries, and vehicles are the first to notice. The air entering the radiator does not cool, circuit water is heated and the temperature rises. Oil deteriorates more rapidly. The vehicle has less power. Shock absorbers for many of its qualities. The brake discs hellish temperatures reach. Also, air conditioning to cool it looks as if no.

Frio extremo cocheFor tests of extreme cold manufacturers often choose Alaska (EE.UU.) or northern Sweden near the Arctic Circle, area known as Lapland, to test at -50 ° C, next to nothing.

Extreme cold, snow, frozen lakes, snowstorms and other guests crushed vehicles. Frozen locks, cushions oil solidified near, tremendous noise when opening and closing the doors, gearshift need 2 hands to shift gears, the conditioner cooling the atmosphere even more,…among other consequences. It all depends on the quality and development of vehicle for which you are performing the test.

If your car, wherever they live, has major faults at normal temperatures, probably did not pass the test of cold and extreme heat…Or yes? You will never know.
