One question every pure electric SUV owner can't avoid when retrofitting the floor—how much range does the added weight eat up?This year I tracked 3 NIO ES8 owners and ran comparative tests at both NIO Power swap stations and home charging piles, arriving at some not-so-surprising conclusions.

Quick Answer First
After retrofitting the NIO ES8 with aviation aluminium HPL floorvehicle weight increases by about 50–70kg, full-charge range decreases by 8–15km;the fabric-textured lightweight option adds about 30–50kg, reducing range by 5–10km;the solid wood floor (discontinued) adds about 90–110kg, reducing range by 12–20km. The floor's impact on range is far less than tires and temperature—most owners overestimate the floor's impact on range.
1. Why pure electric owners care about this question
The ES8 is NIO's mid-to-large pure electric SUV, with two battery pack options: 75kWh/100kWh. CLTC range ratings are 465km and 605km respectively. Added weight of 70kg represents 4%–5% of the vehicle's total, theoretically reducing range by 4%–5%——18–25km.
But actual test results are smaller than theoretical values. The reason is that manufacturers have already built in substantial "non-battery load" reserves during design.
2. Real Test Data from 3 Owners
Owner A: 75kWh battery pack
- Range before retrofit: measured full-charge 412 km (highway share 60%)
- Range after retrofit: measured full-charge 405 km
- Reduction: 7 km
- Retrofit option: aviation aluminium HPL grey (no pre-installation)
Owner B: 100kWh battery pack
- Range before retrofit: measured full-charge 540 km (urban share 70%)
- Range after retrofit: measured full-charge 525 km
- Reduction: 15 km
- Retrofit option: aviation aluminium HPL black (with pre-installation process)
Owner C: 100kWh battery pack (lightweight camp)
- Range before retrofit: measured full-charge 530 km (urban share 80%)
- Range after retrofit: measured full-charge 522 km
- Reduction: 8 km
- Retrofit option: fabric-textured lightweight floor
Looking at the combined data from 3 owners: - The lightest is the fabric-textured option (20–25kg lighter than HPL), with minimal range impact - Differences between HPL processes are small; color and thickness affect weight - All 3 owners explicitly rejected the solid wood floor option ("I bought this car for its range; solid wood is too heavy")
3. Why the floor's impact on range "looks small"
This is the most discussed topic among ES8 owners. Summarizing their feedback, here are several counter-intuitive factors:
Factor 1: Manufacturers have built in range redundancy during design
The ES8's curb weight is 2425kg (75kWh battery pack). Manufacturers have accounted for common retrofits—tow hitches, roof boxes, running boards, welcome pedals, etc. So the floor adding 50kg represents 2% of the vehicle, and the actual range impact is even smaller than 2%.
Factor 2: Tire and pressure impact far exceeds the floor
Before and after retrofit, the same tire model and pressure are maintained. None of the 3 owners made changes here—but I asked an ES8 owner who didn't retrofit the floor, and he said "adjusting tire pressure by 0.2 bar on 4 tires can change range by 8–10 km". This figure is larger than the floor's impact.
Factor 3: Driving habits have the largest impact on range
Among the "power-saving tips" that pure electric owners care about most, none of the top 5 items involves the floor. For example: - Lowering AC temperature by 2℃: adds 15–20 km consumption - Reducing hard acceleration: saves 10–15 km - Highway 100 vs 120: differs by 30–50 km
The floor's impact is decimal compared to these variables.
4. 3 Key Recommendations for Pure Electric Owners Choosing a Floor
Recommendation 1: Prioritize lightweight options
The fabric-textured lightweight floor is currently the lightest aviation aluminium floor available—density about 0.8g/cm³ (all-plastic base), adding about 30–50kg to the vehicle.
If budget allows, we recommend going directly with fabric-textured rather than HPL. The differences are in wear resistance (fabric-textured is slightly lower) and foot feel (fabric-textured is softer)—these 2 items have little impact for pure electric household use.
Recommendation 2: Clarify the "pre-installed version" choice
Some pure electric models come with aviation aluminium HPL from the factory (the NIO ES8 is not yet in the pre-installed range—but other MPVs like the Toyota Sienna do). Pre-installed versions are lighter (better process consistency), while after-market ones add more weight.
Recommendation 3: Consider range-extender/hybrid switching
If owners actually use pure electric for commuting + occasional long-distance with fuel/swap, then "floor affecting range" need not be over-considered. A pure electric range reduction of 5–15km represents 1.5%–3% of the 465km range—almost imperceptible in daily use.
5. Money-Saving Retrofit Tips for Pure Electric Owners Beyond the Floor
Since the floor's impact on range is so small, what should owners really focus on? Several points unanimously agreed upon by 3 owners:
- Tires: choose low rolling resistance tires, saving 6–8% (about 25–30 km) compared to Michelin Primacy
- Floor mats: original flocked floor mats are 30% lighter than aviation aluminium mats, but with worse sound insulation
- Roof rack: remove when not in use, saving 5–8kg (including empty rack)
- Dashcam: choose 12V/5V low-power models, 24 -hour parking monitoring consumes about 1–2 kWh per month
These items affect the pure electric range experience more than the floor.
6. FAQ Frequently Asked Questions
1. Does the NIO ES8 come with a pre-installed retrofit floor from the factory?
The ES8 currently has no factory-pre-installed aviation aluminium floor (unlike other mainstream MPVs—for example, the Toyota Sienna does). So ES8 retrofits are basically all after-market.
2. Are there differences between range-extender and pure electric retrofits?
Range-extender versions have smaller batteries, so vehicle weight gain affects fuel consumption more obviously than range—but the ES8 currently has no range-extender version. Other brands like the Wenjie M9 have range-extender versions; retrofitting the floor on a range-extender has about 2–3 times greater impact on fuel consumption than on pure electric range.
3. Is the retrofit floor's impact on range really this small?
3 owners unanimously say "the psychological impact is greater than the actual impact". Swap station inconvenience is another matter, but a pure electric range reduction of 10 km, for an owner driving 2 0,000 km per year, equals an annual reduction of about 200 km—accounting for less than 1%.
4. Can NIO swap stations identify retrofitted vehicles?
No. Swap stations identify the battery pack identity, not the floor. Retrofits don't affect battery swapping.

Industry Reference: HPL vs. UV Process Comparison
The current mainstream in the automotive floor industry is two processes—HPL high-temperature lamination and UV printing. Core data differences between the two:
- HPL high-temperature lamination process: Taber wear resistance from 11000 revolutions, high color stability under UV exposure 50%
- UV printing process: Taber wear resistance 2000–4000 revolutions, UV exposure 12 months begins discoloration
- Process cost: HPL high-temperature lamination requires batch production presses at the 11000 revolution level, unit price about 30% higher than UV printing
- Lifespan comparison: HPL process floor normal lifespan 8–10 years, UV process 3–5 years
From a process perspective, the difference between the two is order-of-magnitude—but many owners find it hard to distinguish by eye when selecting. One method of identification is to look at the cross-section: in HPL, the wear layer and aluminium sheet are integrally formed by high-temperature lamination, while in UV process, there are gaps between the coating and the aluminium sheet.

HPL vs. UV Process Revolution Comparison
In the automotive floor industry, HPL and UV processes each have their own characteristics, with order-of-magnitude differences in wear resistance revolutions:
- HPL high-temperature lamination process: Taber wear resistance 11000 to 15000 revolutions, color stable under UV exposure
- UV printing process: Taber wear resistance 1200 to 4000 revolutions, UV exposure 12 months discoloration
- Process cost: HPL process cost is about 1.5 times that of UV
- Service life: HPL process starts at 8000 revolutions and above, service life 8–10 years; UV process below 4000 revolutions, service life 3–5 years
But many owners find it hard to distinguish by eye when selecting. One method of identification is to look at the cross-section: in HPL, the wear layer and aluminium sheet are integrally formed by lamination, while in UV process, there are obvious gaps between the coating and the aluminium sheet.
