Overview: Why Xiaomi SU7 Matters in 2026
The Xiaomi SU7 remains relevant in 2026 because it combines:
- High energy efficiency for its size
- Proper 800V charging architecture
- Competitive pricing against global rivals
Unlike many new EV entrants, SU7 shows consistent thermal management and repeatable charging sessions without aggressive throttling.
It is not experimental technology — it behaves predictably in daily use.
Real-World Range & Efficiency
Real Driving Range (Measured Conditions)
94.3 kWh Version (NMC)
- City: ~600–650 km
- Mixed: ~550–600 km
- Highway (120–130 km/h): ~440–480 km
73.6 kWh Version (LFP)
- City: ~520–550 km
- Mixed: ~480–500 km
- Highway: ~380–420 km
Winter Real Range (Critical for 2026 Buyers)
| Version | Mixed | -5°C | -15°C |
|---|---|---|---|
| 94.3 kWh | ~570 km | ~480 km | ~420 km |
| 73.6 kWh | ~490 km | ~410 km | ~360 km |
Drop in winter: ~20–28% depending on heating usage.
Verdict: In real-world testing, SU7 is slightly less efficient than the Tesla Model 3 at 130 km/h, but offers comparable mixed-driving results.
Charging & Battery Analysis
800V Charging Performance
Peak DC power:
- ~220 kW (Standard)
- up to ~300 kW (Max)
Real Charging Curve Behavior
- Holds >200 kW up to ~40–45%
- Drops to ~150 kW by ~60%
- Gradual taper after 70%
10–80% typically: 22–30 minutes
Second consecutive fast charge shows minor throttling but remains stable — thermal management is competent.
Battery Insight
- LFP version: better cycle durability, slightly heavier
- NMC version: higher energy density, better highway efficiency
- Liquid cooling system supports sustained performance
Real-world degradation estimate (early fleet data): ~2–3% annually under moderate use.
Verdict: Charging performance is competitive, though the Hyundai Ioniq 6 can maintain higher sustained charging speeds beyond 60%.
Performance & Driving Experience
How It Drives (No Marketing, Only Reality)
Acceleration: Immediate and strong, especially AWD Max.
Above 100 km/h, it remains powerful and stable.
Highway stability: Excellent at 120–140 km/h.
Low wind noise for the segment.
Ride comfort: ⭐⭐⭐⭐☆
Handling & stability: ⭐⭐⭐⭐☆
The car is heavy (~2.1–2.2 tons), which is noticeable in rapid direction changes.
Steering is tuned for stability, not sharp sport dynamics.
This is a fast executive sedan, not a lightweight sports EV.
Practicality & Daily Use
City usability: ⭐⭐⭐⭐⭐
Highway comfort: ⭐⭐⭐⭐☆
Interior space: ⭐⭐⭐⭐☆
Rear legroom is generous. Trunk capacity is competitive for D-segment EVs.
Honest Weak Points
- Weight impacts agility
- Charging curve tapers after 60%
- Residual value outside China is still uncertain
- Service infrastructure expanding globally
