Recognize these car knowledge clearly and don't be fooled again.

Many people may be influenced by big trucks on the road, thinking that the heavier and more powerful the car is, the safer it is, but the fact is quite unreliable. There is no corresponding relationship between car safety and car weight. The safety of the car mainly depends on the rigidity of the car body, whether the front and rear buffer zones can absorb most of the force generated by the collision, and the facilities such as airbags and seat belts in the car. The weight of the car is more stable and has little to do with the safety of the car; On the contrary, the increase of vehicle weight will reduce the handling limit and braking performance.

When opening and closing the doors, some doors feel heavy and some feel thin, and then many people think that the thin body should be unsafe. Similarly, the insecurity of the car body is also related to the strength of the car body steel frame. For passengers and drivers, it is important to keep the car body intact after a collision. The thin body affects the damage caused by small scratches, and also involves the sound insulation and grade sense of the car. The SUV looks thick and tall, and it has a wide view when sitting in the car. Then many car owners think that SUVs should be safer than cars. There is really no way to say who is safer than who.

After talking about the safety of the car, come on. Many people think that No.98 gasoline must be better than No.92 gasoline, but in fact, the higher the label, the better. The label of gasoline represents the octane number, that is, the explosion resistance of gasoline. The higher the octane number of gasoline, the higher the deflagration temperature. The choice of automobile gasoline grade mainly depends on the compression ratio of the engine. The compression ratio of different engines is different, so the gasoline of each car is different. For expensive vehicles, there is no need to raise the gasoline grade. Just follow the manufacturer's instructions or the tips on the tank cover.

You should know the purpose and purpose of buying a car, and then look at important indicators, such as price, fuel consumption, handling, power, configuration, appearance and so on.
