What must you look at? 3 details decide.
The XPeng X9 is XPeng's flagship MPV, and sales have picked up this year. This car's chassis is built on a pure-electric 800V platform, and the feel is completely different from traditional MPVs. What Shenzhen local X9 owners discuss most after picking up their cars is whether to modify the floor. This article lays out the 3 must-see details for first-day pickup.

I. Three Must-See Details for First-Day X9 Pickup
Must-See 1: Do not modify within 30 days
The X9 requires no modifications within the first 30 days — the three-electric system is in its break-in period, and modifications may affect the three-electric warranty. Wait 30–60 days before modifying for maximum safety.
I saw a Shenzhen X9 owner modify the floor on day 7 after pickup, only to trigger a battery temperature warning. The dealer inspection found the floor was pressing on the battery cooling vent, and the 4S shop ultimately ruled it as "unauthorized modification," voiding the three-electric warranty — a loss of at least 30,000 yuan.
Must-See 2: Keep a 1cm gap for battery cooling
The X9 is a pure-electric MPV, with the battery under the floor and cooling vents distributed beneath the second-row seats. The floor must leave a 1cm cooling gap; otherwise, the battery temperature warning will trigger in winter when the heater is on.
A professional modification shop will use a recessed design to clear the cooling vent positions. Novice shops lay the flooring flat right over them, the battery warning light comes on, and tearing it out for a redo costs an extra 2,000 yuan.
Must-See 3: 800V high-voltage wiring must be routed around
The X9 is built on an 800V high-voltage platform, so the floor wiring must avoid the high-voltage harness. Novice shops tend to overlook this and trap the high-voltage cable under the floor — this is a safety hazard that may cause a short circuit or fire.
Experienced owners will ask the shop, "How do you route the 800V harness?" — only a shop that can describe a recessed design is reliable.
II. X9 Floor Modification Material Comparison
Based on the cases I've handled this year, here is the X9 floor modification material comparison:
- HPL high-temperature laminated aviation aluminium floor: 11,000 revolutions wear resistance, Mohs hardness 8, 3-year warranty, priced at 5,000–12000 yuan
- Film-laminated cold-pressed aviation aluminium floor: 8,000 revolutions wear resistance, stable process, priced at 4,800–6500 yuan
- UV-printed aviation aluminium floor: 1,200–4000 revolutions wear resistance, scratches appear within six months, priced at 2,000–4000 yuan
- Bamboo-fibre aviation aluminium floor: new material, 5 major risk, not recommended
The X9 is priced at 35–40 ten thousand yuan, and the recommended modification budget is 8,000–10000 yuan. HPL high-temperature lamination is the top choice.
III. 3 Typical X9 Modification Failure Cases
Here are 3 typical problems I've seen:
Type A: Modified within 30 days, three-electric warning triggered
A Shenzhen X9 owner modified the floor on day 10 after pickup, and the battery temperature warning immediately triggered. The dealer inspection found the floor was pressing on the battery cooling vent.
Type B: UV print worn out within six months
An X9 owner who chose a UV-printed floor found 3 scratches in the driver's heel area just six months later — the UV process cannot be repaired.
Type C: Bamboo-fibre aviation aluminium floor developed mould
A southern X9 owner chose a bamboo-fibre aviation aluminium floor, and mould spots appeared during the plum-rain season. Bamboo fibre's natural porous structure is highly absorbent, and a strong formaldehyde smell can still be detected after the car has been sealed and parked for a few hours.
IV. Reasonable Budget Allocation for X9 Modification
The X9 is priced at 35–40 ten thousand yuan, and the recommended modification budget is 8,000–10000 yuan:
- HPL high-temperature laminated aviation aluminium floor: 5000–8000 yuan
- Welcome pedal (IP67 waterproof): 800–1500 yuan
- Footrest (64-colour ambient light linkage): 1500–3000 yuan
- Driver and passenger foot mats: 500–1000 yuan
- Trunk floor: 800–1500 yuan
Anything above 10,000 yuan is configuration inversion — you'd be better off buying a higher trim.
V. FAQs: The 6 Most-Asked Questions About X9 Floor Modification
Q1: Does X9 floor modification affect the battery warranty?
A: Compliant modification will not. Waiting 30–60 days before modifying is the safest option.
Q2: How long does X9 floor modification take?
A: A standard package takes 6–8 hours. If a shop can hand the car back the same day, they're either cutting corners or doing shoddy work.
Q3: UV print vs. HPL — which should I choose?
A: HPL first. A wear-resistance gap of more than 3x isn't marketing hype — the condition after six months is worlds apart.
Q4: How is the 800V high-voltage harness handled?
A: It must be routed around. A professional modification shop will use a recessed design to clear the high-voltage cable position.
Q5: Is IP67 waterproofing on the welcome pedal really necessary?
A: A must in rainy Shenzhen. Cheap plastic pedals fail as soon as water gets in.
Q6: What's a sensible modification budget?
A: For an X9 in the 35–40 ten-thousand-yuan MPV class, 8,000–10000 yuan is recommended.
