But with the time of driving longer and longer, lightness has gradually become a legend, driving more and more like the last 5 series, can no longer find the feeling of lightness, only feel the slow steering, heavy body, no longer the silkiness of the car.

(first of all, by the way, my last car was 528li, and the current one is 540i. In order to avoid the monotonous presentation of pure text, I interspersed some pictures, which used to be daytime pictures, but today I will put some pictures for tonight. )

Is it because the car has become so heavy that it affects the handling?

I went to check the relevant information, 95 gasoline density is 0.737g/ml, fill up at a time is about 71 liters (do not bother with me 540i fuel tank can only hold 68 liters, usually more than 5%, empty fuel to fill 71 liters is very normal. 71 liters is about 104 jin, but when I first picked up the car, the fuel tank could only drive 3 kilometers, which could be regarded as completely empty.

In other words, fill up the car, it is quite good to take an adult woman on the car at any time, when there is no empty fuel, it will be for sure.

The dozens of jin of oil consumed accounts for less than 2% of the overall mass of the car. I always thought that the impact of the weight of this oil on handling should be negligible.

I put too many things in the car, some commonly used, some less than a few times a year, or even less than once in a few years.

Since I realized that dozens of jin of oil had such a great impact on the control, I wanted to know how many jin of things I had put in the car.

(there are four things that are not easy to disassemble, car glass film, driving recorder, ETC, a fixed mobile phone bracket).

I weighed everything I took down and recorded it in a spreadsheet.

For example, the heavy ones are child safety seats, tents, ventilated cushions, fully enclosed floor mats, a solid wood locker, a dozen bottles of pure water drinks, large and small, and so on.

If compared with 1/3 full fuel tank, filling up is equal to an increase of 70 jin, plus the 95 jin of things I put on the car, a total of 165jin.

My daily driving is tantamount to carrying a little fat man in the car, or the equivalent of carrying an adult woman and an older child, which is strange to have the sense of control that I had when I first lifted the car.

First, you can never fill it up again in the future, just add 300 yuan, or add 200 yuan if refueling is convenient, unless you have to go far away, calculate the amount of fuel and then decide whether or not to fill it up. It turns out that people who only add 200 yuan to fuel each time may not necessarily be because they have only 200 yuan, but they may also be people who know how to drive cars. )

Second, the things in the car need to be re-screened, and it is not necessary to put the non-essential ones on the car. Children’s safety seats, such as 20 jin, do not run long distances, but only go to the urban area and replace them with a heightening pad with only four or five jin (the goods have been received). The whole surrounding mat is replaced by a pure cushion (all surrounded by 10.3 jin, I throw away the lower layer, leaving only the upper cushion, 3.6 jin, and need to be rebuilt by myself. You can buy Velcro patches online. After it is done, the mat is motionless), pure water drinks, etc., just put two bottles in the car. Instead of moving the whole box of pure water to the trunk, the solid wood locker weighing 9.8 jin will never be put on the car again.

My goal is to put no more than 20 jin of things on the car!

There are many details, such as paper towels not taking the whole bag to the car, taking two-thirds of the paper towels at home, leaving one-third of the paper towels to the car, weighing all the umbrellas at home, finding a light one, removing the instructions on the car, removing the lid on the left side of the trunk, all at home, removing the GPF, it can be reduced by 200g.

Many people read this post, but in fact, I wrote a follow-up post later, because car weight is only one factor that affects the handling, and there are two other factors that are also very important:

Tire pressure

Oil products

If you are interested, you can read the following follow-up post:

After my BMW becomes more and more difficult to drive, the weight of the car is only one factor, and there is a bigger influence.

I’m serious about it, not for fun.

If you think I’m here to be funny, take it as funny.

As long as it can help some people to understand the meaning of weight loss, it will not be in vain for me to write this post.
