Automobiles today are not just mere transport mediums; they are super fast, super comfortable and super attractive. There are cars expensive enough to drain out your entire life savings and there are cars that will make you scream with ecstasy when you pump the accelerator and feel the smooth and powerful engine under you command. Not to forget, the luxuries these cars bring seem to be a lot better than even the most expensive 5 star suite sofa.

Manufacturing these marvels is a marvelous combination of highly skilled engineering and art. The streamlined body of the automobile jam packed with technology, comfort and safety is something to be proud of being alive in this century. But have you ever wondered about the tough and tiring process manufacturers and their staff has to undergo while building a dream machine? Covering the entire topic would take enormous research and writing but we’ll just discuss the one point of safety here, making the car completely air proof and friction free.

The process begins by adoption of the method of checking air leaks from the maritime industry. The process is widely known as checking the tightness of hatch with ultrasound. Ensuring that the automobile is completely sealed and free from any kind of air leakage is the top most safety issue. Unless the automobile has no opening to let even a molecule of air to get inside unwontedly, the automobile would never be able to maintain control at top speeds. The air getting inside from any corner would be pushing the automobile to the opposite side and the driver would have to fight an external force which is unseen but felt harshly.

Braking at top speed requires the car to be in a direction that does not cause it to skid or spin involuntarily. Skidding and spinning can cause it to crash horribly causing damages to even death of the people inside. This is the reason why it has become extremely necessary to maintain total vacuum between the inside and outside of the car. When the automobile is completed and all the fittings have been installed, the car is sent finally to be tested for the hatch cover ultrasonic tightness testing. This test proves that the car is free from any kind of leaks and that it complies with all the safety standards. After the approval from testing the car is sent to its owner who can enjoy rides at the speed of his choice.
