I have seen the anti-collision beam and chassis of this new BYD Han DM-i in the previous few issues. Let’s talk about the interior today.
Door structure
Stamping hinges, integrated doors
Like the old models, the door hinges are stamped hinges that tend to be Japanese and Korean.
The doors are also the same as the old model. They are common integrated stamped all-frame doors in European cars. The door frames are also beautified with black plastic trim.
Soundproof cotton
Large area
The front door interior panel is a hard plastic sealing panel, and the supplier is a German Boze that matches German cars. However, there is no air pressure sensor that stimulates the airbag faster and more accurately, and no installation holes are reserved. The rear door has become an ordinary foam seal, no difference from the old model.
Like the old model, the door interior panel is covered with large area of native sound insulation cotton, which is relatively thick.
Side collision beam
U-shaped
There is a U-shaped side anti-collision beam common to European cars in each front and rear doors.
In addition, there is a reinforcement rib in the front and rear doors of this car.
Rear steel plate
No
The rear seat back of this car cannot be folded down, there is no steel plate, and only a V-shaped support beam, which is exactly the same as the previous BYD Han DM-i.
Rear headrest
complete
The rear seat headrests of this car are very complete and there is no missing.
floor
Sparsely wrapped, native floor
Compared with the old models, the new car has much tighter wrapping.
The sound insulation of the floor is made of white native foam material. Like the old model, the amount of formaldehyde emission needs to be measured using professional instruments.
Through the test, the formaldehyde emission in the floor was measured at 0.117 mg per cubic meter.
The measured value of formaldehyde emission in the seat is 0.044 mg per cubic meter, and the measured value of formaldehyde emission in the ceiling is 0.075 mg per cubic meter.
We still need to emphasize again that our testing methods are relatively extreme, but the test conditions for each car are the same, and the horizontal comparison is fair.
In-car air
In order to more accurately detect the formaldehyde emission in the car, we used “pump sampling” and “phenol reagent spectrophotometry” to test the air in the car. This testing method is a formaldehyde testing method currently used by regular testing institutions.
Test method: Open the door and windows of the test vehicle in a natural environment for complete ventilation; then fix a silicone hose near the driver’s headrest to simulate the person’s breathing position; close the door and window, and park the vehicle in a constant temperature of 23±1℃ and seal and stand for 16 hours; use a sampler to suck out 10 liters of air in the car from the hose pump and react with the phenol reagent; drop the color developer into the phenol reagent and let stand for 15 minutes; use an aldehyde norformaldehyde detector to detect the color developed sample to obtain the results.
After closure in a constant temperature environment of 23±1℃ for 16 hours, the measured air formaldehyde emission in this car was 0.060 mg per cubic meter.
In addition to formaldehyde, TVOC is also an important toxic and harmful gas in the car, and it is one of the main reasons for the strong smell in the car. TVOC refers to the general term for all organic gaseous substances in the space, such as benzene, alkane, aromatic hydrocarbons, olefins… These organic substances will cause harm to human health. Test method: Open the door and windows of the test vehicle in a natural environment for complete ventilation; then fix a silicone hose near the driver’s headrest to simulate the breathing position; close the door and windows, and park the vehicle in an environment with a constant temperature of 23±1℃ and seal and stand for 16 hours; use the Mengpuan MP181 TVOC detector to pump air in the car from the hose until the value is stable, and the final result is obtained.
After closure in a constant temperature environment of 23±1°C for 16 hours, the measurement of the air TVOC release of this car in the car was 1.05 mg per cubic meter.
Summarize
Don’t consider whether it’s worth it or not
Compared with the old model, this new BYD Han DM-i has abandoned the “big mouth” shape and continues to use the Han EV design. It is not so much a change, but rather a unified front face. The interior part has not changed much, but the rotation screen that “Di Fan” is proud of has been cancelled, reducing the cost of software and hardware.
The biggest change in the internal workmanship and materials is the rear suspension, which finally abandoned the criticized three-link “chopsticks” suspension and replaced it with a serious five-link independent rear suspension. The high-pressure fuel tank has also been completely optimized to maximize the use of space and facilitate the installation of larger batteries.
So the question is, is this BYD Han DM-i worth buying? The current price is really low, starting at least 140,000 yuan. If you have this price, you don’t have to consider whether it’s worth it. I just don’t know what people who bought it for more than 200,000 yuan in the past would think. (The conclusions of the measurement data in this article and video are only responsible for this vehicle, and the measurement data is responsible for the publicly announced experimental methods.)
