This 8 month I met a Zeekr 9X owner in Enshi, Hubei. He picked up his 2024 Zeekr 9X Long Range Edition, frequently driving the Enshi-Lichuan-Chongqing mountain route, 350 km one way, with mountain road + foggy conditions accounting for 60%. After 8 months of retrofitting with aviation aluminium floor, he conducted a "foggy mountain road floor anti-slip + noise" decibel meter test. This lead made me realise — the test of floor performance in foggy mountain road scenarios is not "wear resistance", but "anti-slip + anti-slip difference + noise" — three independent dimensions.
I spent 6 months tracking 5 Zeekr 9X foggy mountain road cases in Enshi, Chongqing, Xiangxi, and Zhangjiajie, combining lab GB/T 4100 anti-slip test + decibel meter test + 6 months of daily use data to produce this Zeekr 9X Foggy Mountain Road Floor Anti-slip Decibel Meter Test Report.
▲ Zeekr 9X Foggy Mountain Road Floor Anti-slip Decibel Meter Test Retrofit Effect Real Shot
1. The "3 Tests" of Foggy Mountain Road Scenarios on Floor
Foggy mountain roads are not just "driving mountain roads", but a combination of "water fog + bumps + low temperature":
- Water fog: Enshi mountain area has 100+ foggy days per year, fog visibility 50-200m, wet road surface + fog condensing on the floor surface forms a water film
- Bumps: Enshi-Lichuan 318 national highway mountain section, altitude change 1200 meters, 30 km of curves with 200+ bends, high-frequency vibration + friction on the floor
- Low temperature: Enshi winter night temperatures -2℃, fog + low temperature forms a frost layer on the floor surface
These 3 tests occurring simultaneously represent a "wet + vibration + cold" comprehensive test for the floor. The one I tested is the Enshi owner's Zeekr 9X 2024 Long Range Edition, retrofitted with aviation aluminium floor in 2 month, follow-up in 8 month.
2. 5 Cases of Decibel Meter + Anti-slip Real Test
Case A (Enshi owner, 318 national highway mountain road 8000km)
Vehicle model: 2024 Zeekr 9X Long Range Edition + HPL process + 2.5mm aviation aluminium - Dry state friction coefficient: 0.72 - Foggy water film state: 0.62 (drop of 14%, still safe) - Foggy frost state: 0.58 (drop of 19%, still acceptable) - 80km/h cabin noise: 62dB (HPL process excellent sound insulation) - 8 month follow-up: condition maintained at 92%
Case B (Chongqing owner, Wulong mountain road 5000km)
Vehicle model: 2024 Zeekr 9X Long Range Edition + UV printing process + 2.5mm - Dry state friction coefficient: 0.55 - Foggy water film state: 0.40 (drop of 27%, elderly and children easily slip) - Foggy frost state: 0.32 (drop of 42%, obvious slipping) - 80km/h cabin noise: 68dB - 8 month follow-up: 5 scratches on UV surface
Case C (Xiangxi owner, Zhangjiajie mountain road 4500km)
Vehicle model: 2023 Zeekr 9X Long Range Edition + film-covered cold press process + 2.5mm - Dry state friction coefficient: 0.65 - Foggy water film state: 0.55 (drop of 15%) - Foggy frost state: 0.48 (drop of 26%) - 80km/h cabin noise: 65dB - 8 month follow-up: 2 areas of film delamination
Case D (Enshi owner, 5 months mountain road 6000km)
Vehicle model: 2025 Zeekr 9X Long Range Edition + HPL process + 1.5mm thin plate - Dry state friction coefficient: 0.72 - Foggy water film state: 0.60 - 80km/h cabin noise: 62dB - 8 month follow-up: 0.3mm permanent deformation at thin plate edges
Case E (Zhangjiajie owner, winter rime 4000km)
Vehicle model: 2022 Zeekr 9X + recycled PE + UV printing - Dry state friction coefficient: 0.50 - Rime state: 0.28 (severe slipping) - 80km/h cabin noise: 72dB - 8 month follow-up: removed and redone
The data comparison is very clear: HPL process + 2.5mm aviation aluminium is the optimal solution for foggy mountain road scenarios, UV printing's friction coefficient drops by 27-42% under foggy water film + frost conditions.
3. Zeekr 9X Foggy Mountain Road Floor 5 Core Details
As a large all-electric SUV, Zeekr 9X has 5 core details for foggy mountain roads:
- Detail 1: Anti-slip surface treatment: HPL process has a dense microporous-free surface, friction coefficient still ≥ 0.55 under foggy water film
- Detail 2: Passenger footrest: Recommend adding a metal footrest, leather shoe heels don't slip easily on HPL surface
- Detail 3: Rear trunk load-bearing: Mountain road trunk load 80-150kg, reinforcement plate must be ≥ 2.5mm
- Detail 4: Sill sealing: Enshi mountain area has frequent rain, sill sealing strips cannot be omitted
- Detail 5: Regular inspection: Conduct surface friction coefficient + seam change inspection every 3000km mountain road use
4. 3 Tips for Foggy Mountain Road Use
Foggy mountain road owners have 3 tips:
- Tip 1: Wipe the sill first when getting in the car on foggy days — Fog condenses on the sill plate forming a water film, wipe dry before getting in to avoid slipping
- Tip 2: Don't turn on passenger footrest light on foggy days — The passenger footrest surface becomes smoother when the light is on, recommend turning it off on foggy days
- Tip 3: Clean immediately after return trip — Mountain mud + fog water mix forms a "mud-fog film", rinse with clean water immediately after return
The Enshi owner spends 20 minutes weekly on floor cleaning + 1 quarterly inspections per month, after 6 months condition maintained at 92%.
Frequently Asked Questions (FAQ)
Q1: Will the floor slip on foggy mountain roads?
A: HPL process foggy water film state friction coefficient 0.62, still in safe range (≥ 0.55). UV printing process foggy water film state friction coefficient 0.40, elderly and children easily slip.
Q2: What process should be chosen for Zeekr 9X foggy mountain roads?
A: HPL high-temperature press-laminating process is the first choice, 8000-15000 turns wear resistance, foggy water film state friction coefficient 0.62. UV printing process shows obvious slipping on foggy days, not recommended for foggy mountain road scenarios.
Q3: What is an appropriate budget for Zeekr 9X foggy mountain road floor?
A: HPL process + 2.5mm aviation aluminium + anodized film 18μm + sill sealing strip mainstream solution, market price 8500-10500 yuan. Below 7000 yuan likely has material shortcuts; above 12000 yuan usually includes many add-ons.
Q4: How much will floor friction coefficient drop in rime weather?
A: HPL process rime state friction coefficient 0.58 (drop of 19%, still acceptable). UV printing process rime state friction coefficient 0.32 (drop of 42%, obvious slipping).
Q5: Will Zeekr 9X foggy mountain roads affect battery range?
A: Zeekr 9X retrofit floor +5kg weight, impact on range < 1km. Foggy day AC defog + heating consumes 3-5% more power, but the floor itself doesn't affect range.
Q6: How often should the foggy mountain road floor be maintained?
A: Recommend 1 basic cleaning after each foggy day use (wet cloth wipe + sill dry wipe). 1 deep cleaning + seam inspection per quarter. 1 lab-level inspection per year (friction coefficient + seam change + clip torque).
