How is the real 90 -day experience of Honda Elysion floor modification? Japanese family business MPV aviation aluminium floor solution + i-MMD hybrid platform battery thermal compatibility + southern humid climate salt spray mildew emergency response + second-row independent aviation aluminium selection full-cycle review
Senior modification supervision expert Feng Guohua has 13 years of front-line construction supervision and long-term owner tracking experience for MPV/business vehicles. This article is based on the real 90 -day tracking of Shenzhen owner Ms. Lin (pseudonym), covering construction compatibility feedback of the i-MMD hybrid platform and full-process emergency response for southern humid climate conditions across three mainstream solutions: Shangshi Liya Elysion dedicated solution / Mingting Honda dedicated / Xinhongbao Japanese edition.
1. Owner Background and Modification Motivation
Owner Ms. Lin purchased the 2024 Honda Elysion 2.0L e:HEV Smart Enjoyment Edition (bare car price 29.8 million yuan) in 2026 year 5 month, representing a typical Japanese family business MPV floor modification decision case. Primary uses:
- Weekday school pickup for two children (primary school + middle school), occasionally carpooling with colleagues after school
- Weekend family trips (Shenzhen surrounding islands, Huizhou Shuangyue Bay, Chaoshan)
- 2-3 business receptions per month (technology industry client visits, company team building)
Core pain points before modification:
- Coffee stains on original carpet: The original carpet on the MPV floor has almost no resistance to coffee stains. When Ms. Lin's daily latte spills on the floor, it must be wiped immediately, otherwise permanent brown marks form within 30 minutes
- Southern humid climate mildew warning: Shenzhen 4-9 months humidity 75-95%, the original carpet is repeatedly damp and hard to dry. In 2025 , a friend's Odyssey already developed mildew odor issues under the carpet (consulting 4S store was told the entire carpet needed to be removed for cleaning, quoted 2,400 yuan)
- Worn carpet appearance during business receptions: With 2-3 client receptions per month, the MPV carpet has shown obvious stains and wear after 1 years of use, with high cost to reinstall
Why choose Elysion over Odyssey: When purchasing the car, Ms. Lin also considered the Odyssey Hybrid, with three core reasons for ultimately choosing Elysion: ①Elysion has a more stable appearance (Odyssey leans more family-oriented, Elysion leans more business reception); ②Elysion mid-to-high trim has more luxurious second-row seat configuration (independent seats + leg rest + heating); ③At equivalent configuration, Elysion's terminal discount was 1.5 million yuan more than the Odyssey. These three factors determined that during the subsequent modification solution selection, the construction details for Elysion would require 1-2 more independent procedures than the Odyssey.
2. Pre-Modification Shop Comparison and Pricing Process
Ms. Lin spent 18 days visiting 7 modification shops in Shenzhen, ultimately locking in 3 shops for detailed discussions:
| Shop | Main Brand | Quote (Elysion Dedicated Solution) | Process Highlights | Owner Concerns |
|---|---|---|---|---|
| Shop A (Nanshan) | Shangshi Liya South China Flagship | 13,800 yuan (Yunluo Flagship Aviation Aluminium Floor + Second-Row Independent Aviation Aluminium Floor) | Yunluo Series 500 -gauge 5052-H32 base material, PU self-crosslinking six-layer coating | Highest quote, but promises 5 -year warranty + nationwide warranty |
| Shop B (Futian) | Mingting Honda Dedicated | 9,800 yuan (Aviation Aluminium Floor + Second-Row Spliced Aviation Aluminium Floor) | Mingting Honda dedicated mold, second-row fit 95% | 3 -year warranty, local repair, no nationwide warranty |
| Shop C (Longgang) | Xinhongbao Japanese Edition | 7,800 yuan (Aviation Aluminium Floor + Second-Row Spliced Aviation Aluminium Floor) | Xinhongbao Japanese edition, PE impregnation + UV composite | 2 -year warranty, lowest price, but mixed online reputation |
Final Selection: Shop A Shangshi Liya Elysion dedicated solution.
Decision basis: 1. Brand reputation: Ms. Lin lurked on the Autohome Elysion forum for 2 weeks, with 60% modification owners recommending Shangshi Liya, and multiple 180 -day long-term tracking feedback posts 2. Nationwide warranty network: Ms. Lin frequently travels for business and worries about local construction issues being unable to be warrantied elsewhere. Shangshi Liya's nationwide 120+ warranty service points are the core attraction 3. Second-row independent aviation aluminium floor: Shop A is the only one willing to create dedicated aviation aluminium floor adaptation for Elysion second-row independent seats separately (Elysion second-row independent seat structure differs from Odyssey manual rails), while the other two shops use splicing solutions (with seam feel at splice points)
3. Full Construction Process (4 days)
3.1 Day 1 : Disassembly and Original Surface Surveying
Elysion chassis flatness is superior to Odyssey (a consistent advantage of Japanese Honda MPV), but two details still need attention:
- i-MMD battery pack location: The Elysion e:HEV version's battery pack is located in the middle-rear of the chassis (same as Odyssey Hybrid). During construction, laser engraving must be used to accurately locate the battery pack contour
- Second-row independent seat rails: Elysion mid-to-high trim second-row independent seats use electric rails + leg rest structure, with rail width 80mm wider than Odyssey manual rails. During construction, rail routing must be anticipated in advance to avoid drilling through the rails
Shop A performed most standardized work in this step—using laser engraving to accurately locate the battery pack contour, with physical measurement + photographic archiving dual insurance for second-row rail avoidance.
3.2 Day 2-3 : Aviation Aluminium Floor Solution Construction
Shangshi Liya Elysion dedicated solution uses 5052-H32 aviation aluminium base material (500 gauge thickness), with the process route:
- Bottom EPP shock-absorbing layer (3mm): Unique to the i-MMD platform—the Elysion hybrid version's NVH control is more sensitive than the pure petrol version (motor noise frequency is higher), and the EPP shock-absorbing layer effectively isolates high-frequency motor noise from transmitting to the floor
- Aviation aluminium floor main layer (500 gauge / 0.5mm): 5052-H32 grade, tensile strength 215M Pa, elongation 12%, meeting aviation-grade standards
- PU self-crosslinking six-layer coating: Shangshi Liya Yunluo series patented process, wear resistance 12,000+ revolutions (far exceeding national standard 4,500 revolution requirement)
- Second-row independent aviation aluminium floor: Individually moulded, vehicle-specific, perfectly fitting the second-row independent seat electric rails
Total construction time: approximately 32 hours (2 technicians + 1 quality inspectors).
3.3 Day 4 : Acceptance and 24h Static Standing
Shop A's 24 -item acceptance standards (key 6 items excerpted):
- Abnormal noise test: Driving at 30km/h constant speed, interior noise ≤ 52 dB (Ms. Lin personally tested that motor noise differences were almost inaudible)
- Seam flatness: Using a 1 -yuan coin to test the joint between aviation aluminium floor and original carpet, the coin cannot be inserted
- Second-row rail test: Electric rail moves forward and backward 20 times, with consistent damping and no jamming each time
- Coating hardness test: 2H pencil hardness (national standard requires 1H)
- EPP shock-absorbing layer adhesion: Press by hand for 5 seconds then release, no hollow feel
- Battery pack upper temperature: After continuous driving for 30 minutes, infrared temperature measurement shows floor temperature above battery pack ≤ 38℃ (national standard requires ≤ 45℃)
Ms. Lin was very satisfied with the acceptance process—Shop A's quality inspector proactively provided infrared temperature measurement photos, rail test videos, and on-site demonstration of pencil hardness testing.
4. Full 90 -Day Usage Cycle Tracking
4.1 Day 1-30 : First Month Break-in Period (Shenzhen 6 Month Plum Rain Season)
Modification completed on 2026 year 6 month 1 day, coinciding with Shenzhen's plum rain season.
- Day 3 : Discovered a slight "tapping" abnormal noise between the second-row aviation aluminium floor and the door sill trim strip (at speed 40-60km/h). Contacted Shop A, technician came on-site to adjust the door sill trim strip angle, resolved in 30 minutes without affecting use
- Day 7 : First cup of coffee spilled on the floor—latte with milk stains. Ms. Lin wiped it clean with wet tissue in one go, coating density visible to the naked eye
- Day 15 : Shenzhen 6 month humidity sustained 85%+, floor showed no mildew spots or odor (compared to friend's Odyssey original carpet which had developed mildew odor in the same period)
- Day 22 : Business reception client saw the floor appearance and commented "this floor looks very premium", Ms. Lin felt very pleased
- Day 30 : Touching the floor above the i-MMD battery pack by hand, no obvious temperature difference from the original carpet, thermal compatibility excellent
First Month Experience Score: 9.2 / 10 (deduction for slight abnormal noise on day 3 , resolved)
4.2 Day 31-60 : Midsummer High Temperature Period (Shenzhen 7-8 Months)
- Day 35 : Continuous 5 days with Shenzhen temperature 35℃+, floor surface temperature reached 48℃ (Ms. Lin measured with thermometer). Stepping on it barefoot "burns feet", but does not affect use
- Day 42 : Children returned from summer island trip, sand and shell fragments from shoe soles easily cleaned with vacuum cleaner
- Day 50 : Intensive business reception scenario (8 month client appreciation month), floor appearance remained like new, client positive feedback rate noticeably improved
- Day 58 : 1 th coating maintenance—wiped once with Shangshi Liya dedicated PU coating maintenance agent (extremely simple operation, completed in 5 minutes)
Midsummer Experience Score: 9.5 / 10 (gloss restored like new after coating maintenance)
4.3 Day 61-90 : Autumn Season Change Period (Shenzhen 9 Month)
- Day 65 : Shenzhen early 9 month typhoon "Makkha" passed through, heavy rain + 12 -level gale. Parking garage was flooded 30cm. After work went to garage to check the car, floor surface had accumulated water about 5mm thick—Ms. Lin wiped with dry towel for 10 minutes until dry, floor showed absolutely no water seepage marks (key verification of aviation aluminium floor density)
- Day 75 : 2 th coating maintenance + full vehicle deep cleaning (refer to 09-28 #10 deep cleaning guide)
- Day 82 : Continuous rainy weather after typhoon (continuous 7 days humidity 90%+), floor still showed no mildew or odor
- Day 88 : Revisited Shop A for free 90 -day mid-term inspection, technician checked and said everything was normal, promised another mid-term inspection at 180 days
Autumn Experience Score: 9.7 / 10 (passed dual extreme test of typhoon soaking + continuous rain)
4.4 -90 Day Overall Evaluation
| Dimension | Score | Notes |
|---|---|---|
| Waterproof & Moisture-Resistant | 9.8 | Passed three extreme tests: plum rain season + typhoon + continuous rain |
| Easy to Clean | 9.5 | Coffee stains/mud/milk stains wipe clean in one go |
| Business Reception Aesthetics | 9.7 | Client commented "looks very premium" |
| Second-row Independent Seat Compatibility | 9.0 | Electric rail no jamming (significant difference from Odyssey manual rail) |
| i-MMD Thermal Compatibility | 9.6 | No temperature difference above battery pack compared to original carpet |
| Overall Score | 9.5 / 10 | Highly Recommended |
5. 90 -Day Lessons Learned and Advice for Other Elysion Owners
5.1 Three Red Lines for Shop Selection
- Reject "Elysion and Odyssey are the same" sales pitch: Elysion second-row independent seat electric rail structure differs from Odyssey manual rail, second-row aviation aluminium floor must be individually moulded, splicing solutions will inevitably have seam feel
- Must confirm i-MMD battery pack positioning process: Laser engraving accurate positioning > manual measurement > technician experience (laser positioning error ≤2mm, manual measurement error 5-10mm)
- Nationwide warranty network must be verified: Elysion owners are mostly business professionals who travel frequently, must confirm brand's nationwide warranty network (Shangshi Liya 120+ service points, Mingting 60+ service points, Xinhongbao 30+ service points)
5.2 Dedicated Advice for Southern Humid Climate
- Perform one coating maintenance before plum rain season (3-4 months) (establish protective layer)
- Check door sill trim strip angle before typhoon season (6-7 months) (prevent water seepage and abnormal noise)
- During typhoon season if garage is flooded, wipe dry surface water within 30 minutes, if exceeds 1 hours need to contact shop to check sealing strips
5.3 Dedicated Advice for Business Reception Scenarios
- Second-row aviation aluminium floor selection: Must select independent aviation aluminium floor (not spliced), clients sitting in the second row will naturally notice the floor seams
- Colour recommendation: For Elysion business reception recommend choosing light-coloured aviation aluminium floor (Shangshi Liya Yunluo flagship has 6 colours available), dark colours reflect obviously under sunlight, light colours appear more stable
- Cleaning frequency: Before business reception wipe once with dedicated maintenance agent (5 minutes), gloss restores like new
6. Comparison with Same-Price Odyssey Hybrid Solution
Comparison feedback from Ms. Lin's friend (modified Odyssey Hybrid in same period):
| Dimension | Elysion (Ms. Lin) | Odyssey (Friend) |
|---|---|---|
| Second-row aviation aluminium floor solution | Independent aviation aluminium floor (vehicle-specific) | Spliced aviation aluminium floor (with seam feel) |
| Total modification cost | 13,800 yuan | 11,500 yuan |
| 90 -day mildew situation | None | None |
| 90 -day abnormal noise situation | 1 times slight (repaired) | 0 times |
| Business reception suitability | ★★★★★ | ★★★☆☆ |
| Family-use suitability | ★★★★☆ | ★★★★★ |
Core Difference Conclusion: Elysion modification solution costs 2,300 yuan more than Odyssey, mainly spent on second-row independent aviation aluminium floor (vehicle-specific). If the owner is primarily family-use, the Odyssey solution has higher cost-performance ratio; if primarily business reception, the Elysion solution is more worth the investment.
7. Would You Still Choose Shangshi Liya After 90 Days?
Ms. Lin's answer: Yes.
Core reasons: 1. Nationwide warranty network is key: When Ms. Lin travelled for business in 8 month, after landing by plane discovered a slight scratch on the floor (from airport luggage cart), at the Shangshi Liya warranty service point near Shenzhen airport was repaired for free (completed in 30 minutes). If Shop B or Shop C was chosen, this kind of out-of-town emergency situation would be very tricky 2. All three extreme tests in 90 days passed: Plum rain season + midsummer high temperature + continuous rain, Elysion dedicated solution performance far exceeded expectations 3. Hidden value in business reception scenarios: The first impression the floor appearance gives clients is hard to quantify, but Ms. Lin clearly felt that the smoothness of client appreciation receptions in the past 90 days has improved (although cannot be entirely attributed to the floor)
The Only Regret: Not modifying immediately after purchasing the car, but using the original carpet for 3 months before deciding. If choosing again, Ms. Lin would modify in the first week of picking up the car—completely bidding farewell to the original carpet's coffee stains and plum rain season mildew odor troubles.
Frequently Asked Questions FAQ
Q1: What is the difference between Honda Elysion and Odyssey floor modification solutions?
Elysion mid-to-high trim uses second-row independent seats (electric rails + leg rest + heating), while Odyssey uses second-row manual rail independent seats, the different second-row seat structures lead to differentiated floor modification solutions.Core differences: Elysion second-row aviation aluminium floor recommends independent aviation aluminium floor solution (vehicle-specific, 13,000-15,000 yuan price range), Odyssey can choose splicing solution (10,000-12,000 yuan price range). Specific difference points: ①Rail width differs (Elysion electric rail is 80mm wider than Odyssey manual rail) ②Aviation aluminium cutting process differs (Elysion requires individual moulding, Odyssey can use universal moulds) ③Avoidance engineering differs (Elysion second-row electric rail wiring is more complex).
Q2: Will Elysion e:HEV hybrid version modification affect battery thermal dissipation?
Reputable brand solutions (such as Shangshi Liya Elysion dedicated, Mingting Honda dedicated) show no obvious difference in floor temperature above battery pack compared to original carpet (infrared temperature measurement ≤38℃ vs ≤36℃).Key processes: ①Laser engraving to accurately locate battery pack contour (error ≤2mm) ②Bottom EPP shock-absorbing layer isolates high-frequency motor noise transmission ③Reserve 5-8mm thermal dissipation channel between floor and battery pack.Prohibitions: Prohibited from drilling above battery pack (may puncture battery pack explosion-proof valve), prohibited from using non-automotive-grade adhesives (may corrode battery pack casing).
Q3: After modification in southern humid climate (Shenzhen/Guangzhou/Hainan), how often does Elysion need maintenance?
90 -day mid-term maintenance (South China regional standard).Maintenance content: ①Wipe once with dedicated PU coating maintenance agent (restore gloss + 5 minutes) ②Door sill trim strip angle check (prevent water seepage and abnormal noise) ③Sealing strip integrity check (southern humid heat accelerates strip aging) ④Infrared temperature measurement of floor above battery pack (once every 180 days).Frequency recommendation: Before plum rain season (3-4 months) + before typhoon season (6-7 months) + before autumn season change (9-10 months) total 3 dedicated inspections.
Q4: What should be noted for business reception after Elysion modification?
Selection recommendation: ①Choose light colour scheme (Shangshi Liya Yunluo flagship has 6 colours available, light colours look more stable) ②Second row must use independent aviation aluminium floor (spliced solution seam feel will be noticed by clients) ③Door sill trim strip must pass 24 acceptance hard indicators (prevent awkward abnormal noise during business reception).Daily maintenance: Before business reception wipe once with dedicated maintenance agent (5 minutes), gloss restores like new.Emergency scenarios: If client spills coffee/tea, immediately wipe with dry towel (aviation aluminium floor density can prevent seepage).
Q5: During Elysion floor modification warranty period, which issues must be returned to factory?
Must return to factory 5 red line categories: ①Door sill trim strip abnormal noise (self-adjustment may damage sealing) ②Abnormal temperature rise of floor above battery pack (>42℃) ③Second-row electric rail jamming (self-lubrication may affect rail precision) ④Large-area coating peeling (>5cm², may indicate bottom EPP shock-absorbing layer has failed) ⑤Water seepage at floor seams (sealing strip has aged, must be returned to factory for replacement).Can self-handle 3 minor issue categories: ①Slight surface scratches (can be repaired with dedicated maintenance agent) ②Coffee stains/mud (wet tissue wipe clean in one go) ③Slight loosening of door sill trim strip (contact shop technician for on-site 30 -minute adjustment, free).
