Many people have a potential understanding of cars，There is right and there is wrong，There is right and there is wrong。Let’s chat together today Which ones are right and which ones are wrong~

Most friends who drive manual transmission cars may have a habit，2000 rpm shift，Think that the high speed consumes fuel。Need to replenish oil，2500-3000 is actually the optimal speed range of the engine。2000 shift，Instead, it has entered the low-efficiency range，Need to replenish oil，It will also consume more fuel!

2. The larger the displacement, the more fuel is consumed

Actually，Displacement mainly represents the best working condition seabet ioof the engine。In the high speed range，Large-displacement cars may be more fuel-efficient。Small-displacement cars are more fuel-efficient at low speeds。Generally speaking，Comparison of mid-displacement "Taiwan Balm"，1.8L displacement is more suitable!However，The current engines are somewhat 1.5-1.The 6L engine has also reached 1.8L level，It’s still very good!

3. Small grades are more fuel-efficient than large grades

Due to the fact that most of our country’s road conditions are relatively congested during peak hours，This gives everyone the feeling that small-class cars are more fuel-efficient than large-class cars。Actually driving，Small car due to being affected by the captain、Wide drag coefficient、Restrictions on gearbox configuration and other factors，On the contrary, it is not conducive to its fuel economy。

4. Manual transmission is more fuel-efficient than automatic transmission?

This was indeed the case in the early years，But now the shifting program and transmission efficiency of automatic transmission models are already quite high。Some are even more fuel efficient than manual transmission models!

5. German and American cars use more fuel than Japanese cars?

If you go to all the major forums，You will find out。In fact, fuel consumption is really related to the road and engine technology。In our subconscious，Japanese cars are more fuel efficient。But，The editor has also consulted with Japanese and American car owners。Their fuel consumption is not much different。Improvements in current engine technology，The gap in fuel consumption is gradually narrowing!

seabet my6. The heavier the car, the safer it is?

In many crash tests，Models with heavier weight are indeed safer。But，Crash test hit the wall，Not so representative。Opposite，Some more scientific crash tests in Europe show，The relationship between weight and safety factor is not that big，The structure of the car body is the most important!

7. American cars are safer than Japanese cars?

Various models，The content has been discussed above，The safety of a car is closely related to its structure。It has little to do with the department!

8. Security configuration is particularly important?

For example，ESP is currently one of the important standards for measuring vehicle safety。ESP can only be said to alleviate vehicle safety risks to a certain extent，If you encounter situations such as high-speed spinning，Breaking through the limits of physics，The security system is of no avail。For example，Driving on the highway，There is a situation ahead，Maybe press the brake harder，Crash into it，Maybe it’s not that serious a problem，But give directions，The vehicle will slip or something，The problem is more serious!Do you agree with the above view？Leave a message and tell us~ (The content of the article comes from the Internet，If copyright is involved, please contact us for deletion)
