BYD Qin: Is the cheapest hybrid on the market worth buying?
I have seen the anti-collision beam and chassis of this BYD Qin PLUS DM-i, and found that there are many "cost compromises" compared with Qin Pro. What about the interior part? Let’s talk today.
Door structure
Stamped hinge, integrated door
Door hinge is a common stamping part in Japan and South Korea.
The door is a full-frame door with integrated stamping, and for the sake of beauty, black plastic decorative strips are added to the door frame.
Sound insulation cotton
vary in size
When the front and rear door trim panels are removed, it can be seen that there is a large area of steel plate inside, and only a small part is sealed with styrofoam, but there is no air pressure sensor to assist the airbag to pop up.
The sound insulation cotton of the front and rear doors is about the same size, but compared with the area of the front door, the rear door is relatively larger.
Side anti-collision beam
Square tube shape
There is a square tube-shaped side anti-collision beam commonly used by BYD in the front and rear doors.
There is a reinforcing rib in the front and rear doors.
Rear seat
The steel plate is gone
There was no steel plate in the rear seat, which was cancelled. The Qin Pro rear seat we dismantled before had a complete steel plate. As for why it’s gone, do you need to ask?
Rear headrest
complete
The rear seat headrest is still relatively complete.
floor
Sparse package, native floor
Ordinary plastic tape is used for the large-line package, which is relatively sparse. Previously, Qin Pro’s large-line package was relatively sparse, but the cloth-based tape with high cost was used.
Although the floor filler of this car uses foamed materials, it is treated with a large area of adhesive between it and the carpet. Therefore, it is necessary to use professional instruments to measure the internal formaldehyde release.
Through the test, the measured value of formaldehyde emission in the floor is 0.102 mg per cubic meter.
The measured value of formaldehyde emission from the seat is 0.049 mg/m3, and that from the ceiling is 0.084 mg/m3.
Again, we have to emphasize that our test method is relatively extreme, but the test conditions of each car are the same, and the horizontal comparison is fair.
Interior air
In order to detect the formaldehyde emission in the car air more accurately, we use "pumping sampling" and "phenol reagent spectrophotometry" to test the car air. This test method is the formaldehyde test method used by regular testing institutions at present.
Test method: put the test vehicle in the natural environment, open the door and window for complete ventilation; Then, fix a silicone hose near the driver’s headrest to simulate the breathing position of people; Close the doors and windows, park the vehicle in an environment with a constant temperature of 23 1℃ and seal it for 16 hours; Using a sampler, 10 liters of in-vehicle air is sucked from the hose pump to react with phenol reagent; Dropping the chromogenic agent into phenol reagent, and standing for 15 minutes; Use formaldehyde detector to detect the colored sample and get the result.
After being closed for 16 hours in a constant temperature environment of 23 1℃, the measured value of formaldehyde emission in the air of this car is 0.142 mg per cubic meter.
In addition to formaldehyde, TVOC is also an important toxic and harmful gas, which is one of the main reasons for the strong smell in the car. TVOC refers to all organic gaseous substances in space, such as benzene, alkane, aromatic hydrocarbon and alkene … These organic substances will do harm to human health.
Test method: put the test vehicle in the natural environment, open the door and window for complete ventilation; Then, fix a silicone hose near the driver’s headrest to simulate the breathing position of people; Close the doors and windows, park the vehicle in an environment with a constant temperature of 23 1℃ and seal it for 16 hours; Using the MP181 TVOC detector of Mengpu ‘an, the air in the car is pumped from the hose until the value is stable, and the final result is obtained.
After being closed for 16 hours in a constant temperature environment of 23 1℃, the measured value of TVOC emission from the air inside the car is 1.57 mg per cubic meter.
summary
Self-satisfaction is useless, rational self-improvement
This BYD Qin PLUS DM-i plug-in hybrid model is indeed one of the cheapest hybrid models available on the market at present. However, for the word "cheap", there is no small price to pay. Compared with the previous Qin Pro, it not only canceled the pedestrian protection foam, reduced the pressure relief port, but also replaced the integrated front subframe. The original aluminum alloy horn and rear seat steel plate also disappeared, and the rear suspension also changed from multi-link to torsion beam.
Reducing costs and increasing efficiency also reflects from the side that the cost of BYD’s DM-i hybrid system is not low. If the hybrid is removed, this car will be at the level of 60,000 to 70,000. In fact, the DM-i hybrid is very close to Honda’s i-MMD, and it is difficult to run out of the official 3.9 liters/100 kilometers in daily use. Usually, we can only run about 6-7 liters of fuel consumption.
Each of us hopes that domestic independent brands can be strong and catch up with the world-class level. However, we also need to maintain a normal mentality and face up to our own shortcomings, so that there will be room for improvement and progress. If you just get high, it won’t do you any good. Improving strength depends on self-improvement, don’t always Kung-fu in the mouth! (The conclusion of the measurement data in this article and the video is only responsible for this car, and the measurement data is responsible for the publicized experimental method. )
