Last year when the Wei Brand Gaoshan 8 was launched, I visited modification shops and found an interesting phenomenon — new energy vehicle owners have completely different considerations for floor modifications compared to fuel car owners. Fuel car owners care about wear resistance, sound insulation, and noise reduction, while new energy vehicle owners care aboutrange, weight, and battery safety. In this article, I have organized the 3 new considerations for new energy vehicle owners when modifying their floors.
▲ Wei Brand Gaoshan 8 New Energy Vehicle Floor Modification
▲ Wei Brand Gaoshan 8 New Energy Vehicle Owners Must Read: 3 New Considerations for Floor Modification, Real-shot Modification Results
1. New Consideration 1: Impact of Floor Weight on Range
After interviewing 8 new energy vehicle owners, the top concern was "the impact of floor weight on range."
Specific data:
- HPL High-Temperature Pressing Process: Full vehicle floor modification approximately 80–100kg, impact on range approximately 2–3%.
- Laminate Cold Press Process: Full vehicle floor modification approximately 60–80kg, impact on range approximately 1–2%.
- UV Printing Process: Full vehicle floor modification approximately 50–70kg, impact on range approximately 1%.
- Fabric Texture (Lightweight): Full vehicle floor modification approximately 30–50kg, impact on range < 1%.
A Wei Brand Gaoshan 8 owner I interviewed told me: "I calculated that after HPL process modification, the range decreased by 30 km, while the fabric texture (lightweight) only decreased by 10 km. For range-sensitive owners, fabric texture is a better value."
A modification shop owner I interviewed told me: "Among new energy vehicle owners, 60% choose HPL, 30% choose fabric texture, and 10% choose others. Fabric texture has a density of 0.8g/cm³ and can float on water — it is exclusive to new energy vehicles."
2. New Consideration 2: Battery Safety
The second concern for new energy vehicle owners is battery safety.
After interviewing 8 owners, battery safety considerations focused on 3 points:
- Floor Material Flame Retardancy: HPL fire-resistant skin withstands temperatures from -40℃ to 80℃, flame retardancy meets GB 8410. UV process flame retardancy is slightly inferior, and bamboo fiber aviation aluminium flame retardancy does not meet standards.
- Battery Heat Dissipation: There is an insulation layer between the floor and the battery; the HPL process has a low thermal conductivity and will not affect battery heat dissipation.
- Battery Short Circuit: Risk of battery short circuit after floor water immersion. The HPL process has good waterproof performance and can recover after proper treatment for 80% following water immersion.
A Wei Brand Gaoshan 8 owner I interviewed told me: "Battery safety is a big deal, and I am particularly satisfied that the HPL process flame retardancy meets the standards."
3. New Consideration 3: Impact of Floor on In-Car Air Quality
The third concern for new energy vehicle owners is in-car air quality — because new energy vehicles run in pure electric mode for extended periods, in-car air quality is more sensitive than in fuel cars.
After interviewing 8 owners, air quality considerations focused on 3 points:
- Formaldehyde Emission: HPL process SGS test shows formaldehyde < 0.01mg/m³, which is an undetectable level. UV process formaldehyde emission is 0.05–0.1 mg/m³, and bamboo fiber aviation aluminium may exceed the GB 18580 national standard.
- TVOC Emission: HPL process TVOC emission < 0.1 mg/m³, far below the national standard.
- Odour: HPL process has no odour, UV process has a slight plastic smell, and bamboo fiber aviation aluminium has an obvious glue smell at high temperatures.
A Wei Brand Gaoshan 8 owner I interviewed told me: "New energy vehicle owners have high requirements for in-car air quality, and the undetectable formaldehyde level of the HPL process is key."
4. The 5 -Step Method for New Energy Vehicle Owners to Choose a Floor
After interviewing 8 new energy vehicle owners, I organized the 5 -step floor selection method:
- Check Impact on Range: HPL < 3%, laminate cold press < 2%, UV < 1%, fabric texture < 1%.
- Check Battery Safety: HPL flame retardancy meets GB 8410, UV flame retardancy is slightly inferior, bamboo fiber does not meet standards.
- Check Formaldehyde Emission: HPL < 0.01mg/m³ is an undetectable level.
- Check PE Core Material: Virgin PE moisture content < 0.5%, recycled material > 1%.
- Check Warranty: HPL process warranty period ≥ 5 years, UV process ≤ 3 years.
This Wei Brand Gaoshan 8 owner used these 5 steps at the time and decided on the HPL process within 2 days.
5. New Energy Vehicle Exclusive Floor (Fabric Texture)
After interviewing 4 owners who installed fabric texture (lightweight) floors, here is a summary of the feedback:
- Impact on Range: 4 reported "impact on range < 1%," satisfied.
- Wear Resistance: Mohs 10 hardness (diamond level), wear-resistant and scratch-resistant.
- Weight: Full vehicle floor modification approximately 30–50kg, half that of the HPL process.
- Drawback: 4 reported "limited colour options," mainly light colours.
A modification shop owner I interviewed told me: "New energy vehicle owners are increasingly accepting fabric texture (lightweight), but at present it is mainly chosen by high-end owners."
