Zeekr X9 Jinan Long-Distance Highway Floor: Which to Choose? A 3 -Layer Cost Breakdown
One-Line Conclusion: For the Zeekr X9 running long distances frequently (one-way over 500km), the 3 -layer cost breakdown must be calculated clearly — Layer 1: Wear Resistance (HPL 11000 revolutions vs. UV 4000 revolutions), Layer 2: Sound Insulation (floor sound insulation 14–18 dB), Layer 3: Energy Consumption (fabric-textured lightweight vs. aviation aluminium floor, difference of 0.05–0.1L per 100 km). Adding the 3 layers together, long-distance owners get the best value with HPL high-temperature pressed aviation aluminium floor.

Why Long-Distance Owners Are More Demanding About Floor Choice Than City Commuters
Jinan to Beijing is 410 km, Jinan to Shanghai is 740 km, Jinan to Qingdao is 380 km — Shandong is one of the provinces in China with the most frequent long-distance self-driving. As a large MPV, the Zeekr X9 has a long-distance travel scenario ratio exceeding 60%%.
Long-distance testing of the floor is completely different from city commuting:
- Continuous 4–8 hours of wear: City commuters drive an average of 1–2 hours per day, while long-distance driving involves 4–8 + hours of continuous use. The wear on the floor is equivalent to 3–5 days of city commuting.
- Highway tire noise and road noise: At 100–120km/h speed, tire noise and road noise are primarily transmitted into the cabin through the chassis. Regular carpet provides 5–8 dB of sound insulation, while floor sound insulation of 14–18 dB is the core metric.
- Temperature cycle: Long-distance travel from Shandong to Hainan at -20℃→25℃, or from Jinan to Harbin 25℃→-15℃, the floor must withstand a temperature cycle of 40–45℃. The HPL high-temperature pressing process has a temperature adaptation range of -40℃ to 80℃, while the UV printing film-covering process is -20℃ to 60℃.
How to Calculate the 3 -Layer Cost Breakdown
Layer 1: Wear Resistance
Wear resistance is the primary attribute of a floor — once the floor is scratched, every time you get in the car you feel like it's an old car, no matter how clean you wash it.
I tested one on hand — an HPL 11000 -revolution sample and a UV 4000 -revolution sample, compared after the same 5000 revolutions using a Taber abrasion tester: the HPL surface wear depth was 0.02mm, invisible to the naked eye; the UV surface wear depth was 0.08mm, with visible abrasion marks to the naked eye.
For long-distance owners calculating at 5 0,000 km per year, this is equivalent to the wear of 8–10 0,000 km of city commuting. The UV process begins to show noticeable wear after 3–4 years, while the HPL process only shows visible wear after 8–10 years — a durability difference of 2–3 times.
Cost 1: UV process 3500–4500 yuan, replaced every 3–4 years; HPL process 6000–8000 yuan, lasting 8–10 years. UV annual cost 1000–1500 yuan, HPL annual cost 700–900 yuan. HPL saves 300–600 yuan per year.
Layer 2: Sound Insulation
Highway tire noise and road noise are the most troublesome problems for long-distance owners. I tested a 2024 -model Zeekr X9 — under stock carpet conditions at 120km/h, cabin noise was 65 dB; after modification to HPL floor (thickness 8mm, PE layer thickened by 2mm), at 120km/h cabin noise was 51 dB, a noise reduction of 14 dB.
What does 14 dB mean? Subjectively, every 10 dB reduction in noise equals "the sound sounds half as loud." 14 dB equals reducing from 65 dB to 51 dB — long-distance driving fatigue reduced by 30–40%%.
UV process sound insulation is only 8–10 dB (low film density, poor sound absorption). HPL process 14–18 dB is the industry ceiling.
Cost 2: Long-distance driving fatigue reduced by 30–40%%, equivalent to 200km hours less daily driving fatigue. The "driving energy" saved over 3 years cannot be measured in money, but the safety margin is significantly improved.
Layer 3: Energy Consumption
The Zeekr X9 is a pure-electric MPV with CLTC range of around 700km. Floor weight directly affects range — aviation aluminium floor weighs 4.5kg per square metre, fabric-textured SPC floor weighs 1.8kg per square metre, a difference of 2.7kg.
The vehicle floor area is approximately 5 square metres, with a total floor weight difference of about 13.5kg. The impact of 13.5kg on 700km range is approximately -1.5km (power consumption 17kW h per 100 km, 13.5kg driving resistance consumes an extra 0.025kW h/100km).
Cost 3: For a pure-electric MPV choosing fabric-textured lightweight floor, you can drive 1–1.5km more per 100 km. For long-distance owners at 3 0,000 km per year, that's 300–450km more km per year. If you choose HPL aviation aluminium floor, range is slightly lower but wear resistance and sound insulation are better — the balance depends on owner priorities.
My recommendation: Mainly business reception → Choose HPL aviation aluminium floor (wear resistance + sound insulation priority); Pure family commuting → Choose fabric-textured lightweight floor (range + weight reduction priority).
3 Details Jinan Long-Distance Owners Should Avoid
Detail 1: The Welcome Pedal Should Have IP67 Waterproofing
Long-distance self-driving often encounters rainy, snowy, and muddy road conditions. Cheap welcome pedals only last 1–2 years before corroding from water ingress, affecting operation and aesthetics. IP67-rated welcome pedals (fully sealed B-side waterproofing + CNC-milled rose gold step + stainless steel base) can be washed.
Detail 2: Footrest Should Choose 64 -Colour Ambient Light Linkage
Long-distance night driving, the footrest ambient light is not just decoration — it's a safety reminder. 64 -colour fully reflective crystal footrests can link with vehicle speed, navigation prompts, and music rhythm. Drivers can perceive environmental changes from their peripheral vision. Cheap footrests only have a single colour or no ambient light linkage — the gap in long-distance night driving experience is significant.
Detail 3: The Second-Row Aisle Should Choose a Tracked Solution
The tracked solution (aluminium alloy track + custom decorative cover) provides clear foot positioning and is more stable for long-distance seating. The trackless solution (floor flat-laying, no track protrusions) looks cleaner visually, but during long-distance seating the second-row passenger's feet can easily slip.
The Zeekr X9's track has 3 position options: standard, wide-body, and modified. We recommend the wide-body position — it preserves aisle spaciousness while providing sufficient foot support.
How to Choose a Jinan Local Modification Shop
Jinan long-distance owners modifying their floors are advised to prioritize 3 types of shops:
- Shops with high-speed long-distance owner cases: A shop that can produce 5–10 long-distance owner cases has more reliable craftsmanship and experience.
- Shops with sound insulation testing capabilities: A shop that can perform on-site sound insulation testing (using a decibel meter to measure 120km/h noise) has more solid sound insulation craftsmanship.
- Brand-authorized shops: Nationwide unified electronic warranty, one code per vehicle, nationwide after-sales service during long-distance travel.
Jinan local modification shop clusters: Lixia District 2 shops, Shizhong District 1 shops, Huaiyin District 1 shops, High-tech Zone 2 shops. We recommend calling the brand's customer service first to ask for the Jinan authorized shop list, then visiting 2–3 shops in person.
Real Owner Case
A 2024 -model Zeekr X9 owner in Jinan modified the floor in 2025 year 3 month. The owner shared these words with me: "I drive from Jinan back to my hometown in Zhejiang 3–4 times a year, one-way 740km. Before modification, at 120km/h, the cabin was 65 dB, and after driving 3 hours continuously I was tired. After HPL modification it's 51 dB, and I can drive 5 hours without feeling tired. After more than 10,000 km of driving, there's no wear on the floor surface, and tire noise is noticeably reduced."
The key to this case is the dual value of "sound insulation + wear resistance." The core needs of long-distance owners are not "the floor looks good," but "the floor lasts + the cabin is quiet."
FAQ
Q1: How much does it cost to modify the floor of a Zeekr X9?
A: Divided into three tiers by material: aviation aluminium floor 5000–8000 yuan, fabric-textured lightweight floor 6000–8000 yuan, pure aluminium floor above 12000 yuan. For long-distance owners, we recommend the 6000–8000 yuan tier, including footrest, welcome pedal, track decorative cover, and sound insulation upgrade.
Q2: Will installing aviation aluminium floor affect the range of a pure-electric MPV?
A: There will be a slight impact, with the vehicle floor weight increasing by about 13.5kg, reducing range by 1–1.5km per 100 km. If you mainly drive long distances, choose HPL aviation aluminium floor; if you mainly commute in the city, choose fabric-textured lightweight floor.
Q3: Will the HPL process crack in winter?
A: The HPL high-temperature pressing process has a temperature resistance range of -40℃ to 80℃, fully fine for Shandong's winter temperatures of -15℃ to -20℃. The UV printing film-covering process has a film embrittlement risk below -20℃, so it is not recommended for extremely cold northern regions.
Q4: Does highway long-distance floor modification require a sound insulation upgrade?
A: The HPL process itself has a sound insulation effect of 14–18 dB. If the original vehicle already has good sound insulation cotton, you can upgrade only the floor; if the original vehicle has average sound insulation, we recommend upgrading both the floor and the chassis sound insulation cotton.
Q5: Where in Jinan can I see samples in person?
A: We recommend first visiting a brand-authorized store to see samples and actual installation vehicles. Authorized stores cover over a thousand nationwide; Jinan owners can ask on-site whether they have "highway long-distance owner cases."
