We went to the restaurant for dinner, the lobby was palatial and the tables were very clean, right? Inside the kitchen it may not be so clean.
The invisible place may be the place where business people like to "save costs" the most, and the same is true for car manufacturers.
It is the place that the person who buys the car does not pay much attention to or even can't see, he will have to find a way to save this money, and buying a house is also the same reason, not much to say.
Suspension
Let's start with the first one: vehicle suspension. For the more common operation, the rear suspension is changed from a multi-link to a torsion beam.
For example, the multi-link independent suspension used in the whole series before the Mazda 3 Axela was replaced, and after the replacement, the unification was changed to a torsion beam suspension.
The reason why I switched to this one is mainly because it is cheap.
For example, when Sagitar had a broken shaft problem a few years ago, the Securities Daily reported that if Sagitar's torsion beam suspension was to be replaced with an independent suspension, the material cost was about 3,000 to 4,000 yuan.
The reason why manufacturers will use their brains to save money in this place is because most friends will not put the car up to see, and they do not know what this part is used for.
Of course, car enthusiasts can understand, but most of them are driving a car to work, not how to see, do not understand, do not care, people are in this place to use their brains.
The "2019 China Automobile Consumption Trend Report" released by The Huge Engine and the China Automobile Dealers Association said.
The main factors that consumers consider when buying a car, you listen, appearance, safety, price, power, brand, etc., is not written about the suspension, chassis and other such things.
Isn't that the case with buying a house? Generally speaking, it is not likely that anyone will pay attention to how many steel bars are used in this building, and what is the number of cement? People don't look at this thing, okay?
Generally look at a few rooms, a few halls and a few bathrooms, how much is the area of the pool, you will not think of that thing, right?
Collision avoidance beams
Place 2: Anti-collision beams, especially rear anti-collision beams.
This thing used to be said a lot on the Internet, and now it is still the hardest hit area of the so-called "moving knives" of many manufacturers.
Some small cars, compact models, such as: Volkswagen Polo, Nissan Qida, I said before, the rear anti-collision beam directly did not.
There are also some cars that have anti-collision beams, but secretly change the material of an anti-collision beam.
For example: some models of foam anti-collision beams are not iron, replaced by foam, others are plastic anti-collision beams or something, there have been many before.
We also want to explain the truth, so I will not mention the model and brand more.
The cost of an anti-collision beam is actually not very cheap, is not just a steel bar? Above a treasure, casually search, refer to play, anti-collision beam cheap 1, 200 yuan, a little better 4, 500 yuan.
It sounds like a few hundred dollars, my tens of thousands of cars, hundreds of dollars, small can not be calculated, people's sales if there are 500,000 units, 1 million units, 1 million units multiplied by 400 yuan, 500 yuan, this is astronomical.
People even want to use their brains on a doorknob, not to mention a few hundred dollars of anti-collision beams.
But to our place, a car for a few hundred dollars, it seems that it is not very expensive, but the impact of the anti-collision beam itself on the safety of the car or the role is not small.
Yan Xiaoxiao, Yu Guangxu and others published a paper in the journal Journal of Chongqing University of Technology (Natural Science), "Analysis of the Impact of Rear Collision Beam on the Safety Performance of Rear Collision Vehicle", which was tested.
Collisions occur at the same speed, and the deformation of the longitudinal beam of the car is 24mm less than that of the ultra-high-strength plate as an anti-collision beam and the absence of an anti-collision beam.
At the same time, the rear anti-collision beam can also reduce the damage suffered by the members of the car when the back bump, the higher the strength of the collision beam, the lower the damage value of the dummy.
Don't remember too complicated, to say that when there is a beam in the back that is rear-ended, the loss of the car will be smaller, and the risk of injury to the people inside will be reduced.
Engine acoustic cotton
Let's talk about the third place to think about: the engine acoustic cotton, which is installed on the engine cover.
Ask your friends, how many times do you open the engine cover of your car? Open this lid, do you look down at the engine, or do you look up to see if there is anything on the reverse side of the lid?
Most ordinary users will not look at this, are busy looking for where the glass water is added, there is no time to look up.
The role of sound insulation cotton, in addition to sound insulation, there is actually heat insulation.
A car home has done experiments: in the case of idle speed, the noise of the car with sound insulation cotton is reduced by 2.1 decibels.
The temperature test of the engine compartment cover is also relatively large, and the difference between the two is about 18.2 ° C, which is basically the difference between mild scalding.
But many cars have lost this thing at the lowest end, leaving only the bayonet with soundproof cotton.
So, you often see, some cars the hood is lifted, from the bottom up, all are forks, bars, and such holes and what is this, a lot of cars are like this, do not name.
The cheapest enterprising version is no engine sound insulation cotton, but above it has, do not look at it is a layer of soundproof cotton, not cheap, continue to search online you search for good.
BMW 3 series sound insulation cotton also costs more than 100 yuan, if it is the original factory, hundreds of large.
The interior of the car is soundproofed with cotton
In addition to the engine acoustic cotton, the soundproof cotton inside the car is also a so-called "good place" to use your brain to save money.
Zhejiang Satellite TV's "1818 GoldenEye" was reported in 2018.
An Audi 4S store in Ningbo should take the initiative to replace the audi A4L of the customer with soundproof cotton, mainly because there is a shortage of quality in a batch of soundproof cotton, which will lead to a serious odor in the car. Something very famous, right?
And not only this car, according to the statement issued by Volkswagen at the time, the models with problematic acoustic cotton included Audi's A4L, Q5, A3, Volkswagen's Magotan, CC, Golf, and Skoda Octavia.
Production time continued from 2013 to 2016.
Relative to this relatively poor quality of soundproof cotton, not only is it a problem of saving money, but more importantly, its odor does have a certain relationship with formaldehyde, which is easy to affect physical health.
Not to say that the public is scolding over there, but for example, many car companies and brands have such a situation and phenomenon.
Ma Hui, Song Jianwei and others published a paper in the journal Tianjin Automobile, "Preliminary Study on reducing the harmful gas (VOC) content of soundproof cotton", which said above.
Among the harmful gases in the car, the main source of formaldehyde is the sound insulation cotton used in carpets, roofs, door interior panels, etc. in the interior parts of the car.
Fog lights and reversing lights
What is the last cost-saving location? Lights. The lights are not bright we can see, he still dares to save? Many cars have only one reversing light and one rear fog light.
This and the anti-collision beam actually have a certain similarity, mainly why? There is no mandatory provision.
For example, the national standard GB 4785-2019 "Regulations on the Installation of External Lighting and Optical Signal Devices for Automobiles and Trailers", mentioned above.
Front fog lights are optional, only the rear fog lights are equipped with at least one, then many of them are equipped with one.
The front fog lamp is optional, the meaning of the choice is that it can be installed or not installed, the choice is not installed, is not it all money? Right? Many car companies do this.
For example, when reading a book, the teacher assigns an assignment and says, "The front is the homework, and the back is called an additional question, which can be done or not." "You see how many people do it?" Right?
There is also a data on the industry information network: the matching price of a single fog lamp is about 50 yuan, if you reduce 2 front fog lights and 1 rear fog light, each car saves 150 yuan.
Selling 1 million cars a year multiplied by 150, "Oh" I can't do math, I can't keep up, a lot of money.
Regulations and standards are uneven, and consumers are not paying attention
Therefore, in general, the reason why car companies can accurately cut the knife in the 5 places mentioned above is because the relevant domestic regulations and standards are set there, that is, you can do this, and there are loopholes to drill.
On the other hand, many friends who buy a car really don't pay attention to these problems, even if they look at the eyes, they don't necessarily understand what the meaning is.
Car companies cancel the spare tire, is the manufacturer to reduce the allocation to save money
Many friends also said: "Now you don't say what just happened, spare tires, spare tires, many car companies are about to lose, and the spare tires in the car will be gone." ”
Is this thing designed to save costs? Or is it that the new ones have gone to learn BMW, and they can't use this thing? Which would be better? Which would be better for ourselves?
The joint venture car is cheap and the configuration is high, and the configuration here is low, the price has become higher, where is the courage? The reduction in the joint venture car is so serious, why are so many people still buying there?
There are also many friends who are saying: "Don't affect security, other configurations are actually fine, aren't they?" Just give me a cheaper car with your car. ”
What exactly is the configuration and safety of the car related? Which configurations must not be decommissioned?
Keywords: de-allocation
Want to know these are very simple, pay attention to the WeChat public account "spare tire car", reply to the keyword "reduction" can be.
I this public number, every day will give you a piece of car practical small dry goods, text, audio, video have, pick your favorite version on it, "spare tire said car" waiting for you to play Oh.
