After looking at the impact beam and chassis of this BYD Song L EV, what about the interior part? Let's talk about it today.

Door structure
Forged hinges, integrated doors
The door hinges of this Song L are forged parts that are common in European cars.
This car uses a frameless door design.
Soundproof cotton
Large area
When I removed the door trim panels, I saw that the interior was made of all-plastic sealing plates, which is called "plastic floor door module". This is the first time we have seen such a seal on a BYD car, and this design is generally commonly used in BBA luxury cars.
The supplier of sealing plates is the well-known Brose Brose! That is, the main supplier of Volkswagen, Audi, Mercedes-Benz and BMW! It seems that BYD is really willing to spend money for this car this time!
A barometric pressure sensor is installed on the front door to assist the airbag to deploy faster and more accurately.
The door trim panels are covered with a large area of white virgin acoustic cotton.
Side impact beams
W-shaped
The front and rear doors are each equipped with a W-shaped side impact beam and a layer of reinforcing steel plates, which is missing from the Song PLUS.
There is one stiffener for the front door and two stiffeners for the rear door.
Rear seats
There are steel plates
The rear seats of the Song PLUS do not have steel plates, and the backrest of the rear seats of this Song L actually has steel plates! It is very rare in BYD cars. I can't help but ask, even BYD has a rear steel plate, and those who say that the rear steel plate is not important, how to explain it?
Rear headrests
Complete
The rear headrest is very complete, not only has an independent metal frame, but also can be adjusted up and down.
floor
Tightly wrapped, virgin flooring
The large thread is wrapped very tightly, and it is also made of good quality cloth tape.
The floor filling is made of virgin foam material, and the amount of formaldehyde emitted also needs to be measured with professional instruments.
Through testing, the formaldehyde emission in the floor was measured at 0.176 milligrams per cubic meter.
Formaldehyde emissions were measured at 0.023 milligrams per cubic meter for the seats and 0.113 milligrams per cubic meter for the headliners.
Again, we have to stress that our testing methods are relatively extreme, but the test conditions are the same for each car, and the side-by-side comparison is fair.
Interior air
In order to more accurately detect the formaldehyde emission in the interior air, we use "pump sampling" and "phenol reagent spectrophotometry" to test the interior air. This test method is the formaldehyde test method currently used by formal testing institutions.
Test method: The test vehicle will be completely ventilated in a natural environment, with the doors and windows opened; Subsequently, a silicone hose is fixed near the driver's headrest to simulate the person's breathing position; Close the doors and windows, park the vehicle in a constant temperature of 23±1°C and seal it for 16 hours; Use a sampler to suck out 10 liters of air from the hose pump and react with the phenol reagent; The chromogenic agent was dropped into the phenolic reagent and allowed to stand for 15 minutes; The aldehyde n-formaldehyde detector was used to test the colored samples and obtain the results.
After 16 hours of containment at a constant temperature of 23±1°C, the car's interior air formaldehyde emissions were measured at 0.058 milligrams 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 is a general term for all organic gaseous substances in space, such as benzene, alkanes, aromatics, and alkenes...... These organic substances can cause harm to human health.
Test method: The test vehicle will be completely ventilated in a natural environment, with the doors and windows opened; Subsequently, a silicone hose is fixed near the driver's headrest to simulate the person's breathing position; Close the doors and windows, park the vehicle in a constant temperature of 23±1°C and seal it for 16 hours; The MP181 TVOC detector was used to suck the air in the car from the hose pump until the value was stable, and the final result was obtained.
After 16 hours of containment at a constant temperature of 23±1°C, the vehicle's cabin air TVOC emission was measured at 1.11 milligrams per cubic meter.
summary
BYD that has never been seen before!
This BYD Song L EV has been greatly improved, and it is completely different from the BYD we dismantled before. It can be said that this is a BYD that we have never seen, the workmanship materials are very surprising, I didn't expect that BYD, which has always been diligent and thrifty, has also begun to use aluminum alloy anti-collision beams, and also began to use active air intake grilles, as well as auxiliary anti-collision beams, and even the energy-absorbing box is made of aluminum alloy. The chassis actually uses aluminum alloy double-ball double-wishbone front overhang, five-link rear overhang, and even the battery is equipped with explosion-proof pressure relief valves.
What's even more unexpected is that the doors are made of Brose, the royal supplier of Volkswagen, Audi, Mercedes-Benz and BMW! The most commendable thing is that the backrests of the rear seats are actually equipped with steel plates! I can't help but ask, what explanation do those who say "the steel plate in the back row is useless" make now? BYD has installed the rear steel plate itself, so you don't have to bother to explain! (The conclusion of the measurement data in this article and video is only responsible for the vehicle, and the measurement data is responsible for the published experimental method.) ）
