▲ BYD Xia Pickup Day: 3 Inspection Details Beginners Must See modification effect live photo
Direct Answer Up Front
On BYD Xia pickup day, you must focus on three things: floor flatness and seams, formaldehyde and odors, and clip load-bearing and edge sealing. This article takes an authoritative third-party perspective and, combined with the HPL high-temperature lamination process route, provides an actionable inspection checklist.
1. Scenario Introduction: Why Is the 'Pickup Day' Node Most Easily Overlooked
Last year, a car owner friend in Beijing came to consult me. After picking up his BYD Xia and driving it for a week, he discovered the floor edge had lifted, with obvious glue residue at the rubber strip position. When he went back to the store to negotiate, the other party shut him down with 'you signed off on it.' I have handled more than one such case. On pickup day, people are in an excited state, with all their attention on the center control screen and seat ventilation. The floor is often the last thing they glance at—precisely this 'last glance' determines whether you will be repeatedly troubled by odors, edge lifting, and loosening over the next three to five years of use.
As a mid-to-large MPV, the BYD Xia's rear floor flatness is very sensitive to floor installation. The transition between the original carpet and the modified floor, the cutting precision of the pedal area, and the edge finishing near the second-row sliding rails are all high-incidence problem areas. If you don't inspect on pickup day, the cost of post-event rights protection is extremely high.
2. Core Data: Several Hard Indicators to Check During Floor Inspection
A set of data tested in the lab left a deep impression on me: HPL high-temperature lamination flooring can reach 11000 revolutions in standard wear resistance tests, with Mohs hardness of 8 ; UV printing process wear resistance is generally in the 1200–4000 revolution range, with Mohs hardness of only 3–4 . The difference between the two is not 'a bit better' or 'a bit worse'—it's a generational gap.
More critical is formaldehyde emission. The HPL route has been tested to reach an undetectable level of <0.01mg/m³, while UV printing combined with bamboo fiber aviation aluminium floor routes tend to release excessive amounts after high-temperature sun exposure—this is the most frequently reported feedback from car owners in Guangdong and Hainan. After a morning of summer sun exposure, the pungent smell when entering the car often originates from the floor adhesive layer and bamboo fiber substrate.
In terms of sound insulation, HPL flooring has been tested to reduce noise by 14–18dB, equivalent to going directly from a 'marketplace' environment to an 'office' level. When I asked a circle of modification shop owners about this number, their feedback was 'for cars with HPL flooring installed, noise complaints from owners are virtually zero,' while the lightweight fabric-textured flooring, though its low density (0.8g/cm³) benefits new energy consumption reduction, performs weaker in sound insulation.
3. Technical Comparison: The Essential Difference Between HPL and UV Printing
Many car owners can't tell the difference between HPL and UV. Here I'll explain it clearly through a Q&A format:
Q: Is HPL just a layer of sticker? No. HPL (High Pressure Laminate), the full name for high-pressure laminate, is formed by pressing multiple layers of resin-impregnated kraft paper together under high temperature (>160℃) and high pressure (>10MPa). UV printing, on the other hand, sprays UV ink on the substrate surface and then cures it with ultraviolet light—essentially 'paint spraying + light curing.'
Q: What's the difference in actual use? Earlier this spring, I visited a modification shop in Shenzhen and saw a BYD Xia that had been driven for three years—the HPL flooring surface had only minor scratches and the color had basically not faded; next to it was the same model car that had only been driven for eight months, fitted with UV printing flooring, where obvious ink peeling had already appeared at the armrest position, revealing the base color. The shop owner pointed at that car and said, 'this customer has come back for after-sales service more than once.'
Q: So why do people still choose UV? Cost. UV process equipment has a low entry barrier, and the unit price can reach one-third of HPL. For car owners using it as a short-term transitional option, it's barely usable, but if you plan to drive for more than three years, the UV weather resistance issues will explode all at once.
4. Buying Guide: 3 Inspection Details on Pickup Day
The following checklist is what I summarized after seeing enough rights-protection cases:
- Seam and Flatness Inspection: Crouch down and use your palm to press flat against the floor surface, feeling across from the front-row sliding rails to the trunk. Any 'step feel' exceeding 1mm, directly ask the store to rectify, otherwise dirt will accumulate in the future.
- Formaldehyde and Odor Inspection: On pickup day, close the windows and sun-bake for 10 minutes, then open the door and take a deep breath. Pungent, eye-stinging, sour—any one of these reactions indicates a problem with the adhesive layer or substrate. I saw one car where the owner didn't pay attention during inspection; three months later, the child got carsick in the car, and testing revealed it exceeded the standard by nearly 4 times.
- Load-Bearing and Clip Inspection: Use your heel to firmly stomp the second-row sliding rail coverage area and the pedal edge, then pull all edge clips by hand. A qualified product should pass the 100KG pull-down test without loosening. The mainstream aviation aluminium floor process is 200 -gauge aluminum plate + 50 -gauge bottom aluminum plate (with PE buffer layer in between). If the store uses 500 -gauge 6061 pure aluminum (Yunluo series, 12000+ yuan), that essentially falls under a high-end custom solution.
Addendum: Don't take the three words 'aviation aluminium floor' at face value. The industry's five fatal defects of bamboo fiber aviation aluminium floor must be watched out for—excessive formaldehyde, water absorption and mold, bamboo borer insect erosion, substandard flame retardancy, and pungent odor at the cross-section. If any one of these five items is hit, the entire floor must be redone.
5. FAQs
Q1: What if I didn't inspect on pickup day and find a problem afterward? Keep on-site photos, surveillance recordings, and construction documents, and submit a written request to the store as soon as possible. If the other party refuses compensation, you can file a complaint with the market regulatory department or go for third-party testing.
Q2: What's a reasonable price for BYD Xia modified flooring? HPL process full-vehicle construction is usually in the 8000–15000 yuan range; UV printing process 3000–6000 yuan; lightweight fabric-textured flooring 5000–9000 yuan. Significantly lower than this range should raise a red flag.
Q3: How to choose between HPL and aviation aluminium? HPL emphasizes wear resistance and quietness, while aviation aluminium emphasizes luxurious texture and waterproofing. For primarily household use, choose HPL; for frequent business reception, choose aviation aluminium.
Q4: Does the BYD Xia's original carpet still need modification? The original carpet has weak sound insulation, stain resistance, and wear resistance. Most MPV owners will upgrade the flooring within six months.
Q5: How long is the construction period generally? HPL full-vehicle construction is about 1–2 days; UV printing about 1 days; aviation aluminium custom solution 3–5 days.
Q6: How to determine which process the store uses? Ask the store to provide process specifications and testing reports. HPL process will have core indicators such as wear resistance revolutions (≥8000 revolutions), formaldehyde testing (<0.01mg/m³), Mohs hardness, etc.; UV process typically does not proactively provide such data.
