Xiaomi has kicked off 2026 with a significant update to the SU7, opening pre-sales in China from RMB 229,900 to RMB 309,900 ahead of an April launch. The revised electric sedan brings meaningful hardware upgrades rather than a simple facelift: a new 752V/897V high-voltage architecture, standard lidar across the range, a jump to 700 TOPS assisted-driving compute, stronger crash structures, and a headline CLTC range of up to 902 km for the SU7 Pro. Arriving as China’s first 2026 fuel-price adjustment was left unchanged after three prior declines, the new SU7 lands in a market where EV value, charging speed, and running costs are under even sharper consumer focus.
Xiaomi SU7 2026: What Changed
The updated Xiaomi SU7 remains a three-trim lineup — SU7, SU7 Pro, and SU7 Max — but nearly every core area has been revised.
Key upgrades include:
- Pre-sale price: RMB 229,900-309,900
- China launch: April 2026
- Lineup: 3 variants
- New maximum CLTC range: 902 km on SU7 Pro
- Standard assisted-driving compute: 700 TOPS across all trims
- Standard lidar: now fitted across the full lineup
- Safety airbags: increased from 7 to 9
- Structural upgrade: 2200 MPa hot-formed steel door beams standard
- New embedded anti-roll structure across the range
This is notable because Xiaomi has not simply added cosmetic tweaks. It has addressed several areas that Chinese EV buyers increasingly scrutinize: real hardware parity between trims, safety credibility, and faster charging supported by higher-voltage electrical systems.
Pricing and Core Specs
Below is a snapshot of the main numbers announced during pre-sales.
| Model | Pre-sale Price | Power | CLTC Range | Platform Voltage | Notable Chassis/Tech |
|---|---|---|---|---|---|
| Xiaomi SU7 | RMB 229,900 | 320 hp | 720 km | 752V | Standard lidar, 700 TOPS |
| Xiaomi SU7 Pro | Not individually specified in source | 320 hp | 902 km | 752V | Dual-chamber air suspension + CDC |
| Xiaomi SU7 Max | RMB 309,900 | 690 hp | 835 km | 897V | Brembo brakes, dual-chamber air suspension + CDC |
For context, AutoHome reports the updated range figures versus the outgoing car as follows:
- SU7: 700 km to 720 km
- SU7 Pro: 830 km to 902 km
- SU7 Max: 800 km to 835 km
The biggest headline is clearly the 72 km range increase on the Pro version, pushing it beyond the psychologically important 900 km mark under China’s CLTC cycle.
Charging, Performance, and High-Voltage Tech
One of the most important technical shifts is underneath the skin. The standard and Pro models move from a 400V architecture to 752V, while the Max goes from 871V to 897V, effectively entering the 900V class.
That matters for two reasons:
- Faster charging potential, especially on suitable high-power DC fast chargers
- Improved efficiency under load, an increasingly important battleground in China’s premium EV sedan segment
Xiaomi also replaces the previous V6/V6s motor setup with the new V6s Plus motor.
Power gains
| Model Group | Previous Output | New Output |
|---|---|---|
| Standard / Pro | 299 hp | 320 hp |
| Max | 673 hp | 690 hp |
For the SU7 Max, Xiaomi says 15-minute charging replenishment increases from 510 km to 670 km. Even allowing for the generous CLTC cycle, that is a substantial improvement and directly targets one of the key consumer anxieties around long-distance EV usability.
Safety Upgrades Are Arguably the Bigger Story
In China’s EV market, software and acceleration often dominate headlines. But Xiaomi’s most strategically important update may be safety.
The 2026 SU7 adds:
- 9 airbags, up from 7
- 2200 MPa hot-formed steel anti-collision door beams standard across the lineup
- An embedded anti-roll structure on all variants
- Standard front four-piston fixed calipers
- On the Max: Brembo calipers, drilled brake discs, and low-metal brake pads
These are not superficial changes. They respond to a broader industry shift in China, where buyers and regulators are paying closer attention to passive safety, braking hardware, and structural integrity — not just battery range and cockpit screens.
That emphasis is especially relevant as the market matures. In the early EV boom, many brands sold on novelty and connectivity. In 2026, consumers are more likely to compare crash structures, braking packages, suspension sophistication, and assisted-driving sensor suites with the same intensity once reserved for smartphone chips.
Assisted Driving: Xiaomi Standardizes Lidar
Another major move is on advanced driver-assistance hardware. Previously, some lower trims lacked lidar and used lower compute capacity. With the updated SU7, Xiaomi has removed that gap.
New assisted-driving baseline
- Lidar now standard on all versions
- 700 TOPS compute standard across the lineup
- All trims upgraded to Xiaomi HAD
This is strategically smart. Chinese consumers have become highly sensitive to trim fragmentation, especially when brands market advanced intelligent driving. Standardizing lidar and compute reduces buyer confusion and strengthens Xiaomi’s positioning against rivals that reserve premium ADAS hardware for upper trims.
In practical terms, this should also help Xiaomi build a more unified software stack, making fleet learning and feature rollout easier over time.
Exterior and Interior Tweaks Are Minor but Targeted
Visually, the changes are evolutionary rather than radical.
Highlights include:
- Revised front bumper grille design
- New Capri Blue paint option
- New 20-inch wheel design
- Rear tire width increased to 265 mm while fronts remain 245 mm
- Improved grip from the wider rear setup
Inside, Xiaomi has focused on perceived quality and usability:
- New Dark Night Black interior theme
- Updated steering wheel design inspired by the YU7
- More soft-touch material coverage
- Revised stitching on seats and door panels
- Updated physical button design in the center tunnel
- Three-layer ambient lighting system
None of these changes transforms the cabin concept, but together they suggest Xiaomi is listening to early user feedback and trying to refine the ownership experience rather than reinvent it.
Market Context: EVs Gain an Edge as Fuel Prices Stall
The timing is also interesting. According to AutoHome, China’s first domestic fuel-price adjustment of 2026, on January 6, was left unchanged because the adjustment amount was less than RMB 50 per ton, the threshold under the country’s pricing mechanism.
2025 China fuel-price adjustment snapshot
| Metric | 2025 Total |
|---|---|
| Adjustment windows | 25 |
| Price increases | 7 |
| Price cuts | 12 |
| Unchanged rounds | 6 |
| Total rounds with movement | 19 |
After a run of declines and then a no-change adjustment, ICE operating costs are not under the same immediate pressure they would be in a sharp oil spike environment. Yet this does not weaken the EV case. If anything, it raises the bar: EV makers must now win not only on cost-per-kilometer, but on product quality, charging convenience, software, and safety.
That is precisely where Xiaomi is trying to push the SU7.
Why This Matters
The updated SU7 says a lot about the direction of the Chinese EV market in 2026.
1. Range alone is no longer enough
A 902 km CLTC figure is excellent for marketing, but Xiaomi paired it with faster charging, better braking, and stronger passive safety. That combination is far more persuasive than chasing headline range alone.
2. Hardware democratization is accelerating
By making lidar and 700 TOPS compute standard, Xiaomi is reflecting a wider market trend: premium intelligent-driving hardware is moving down the price ladder faster than many expected.
3. 800V-plus platforms are becoming mainstream
The move to 752V on mainstream trims and nearly 900V on the Max shows how quickly China’s EV industry is normalizing high-voltage architectures that were once premium showcases.
4. Xiaomi is evolving from disruptor to serious automaker
The first phase of Xiaomi Auto was about attention and market entry. This update feels more like the work of a company settling into the discipline of annual model-year improvement: chassis tuning, safety engineering, charging architecture, and trim rationalization.
Competitive Take: Where SU7 Stands Now
The Chinese EV sedan segment remains intensely competitive, with pressure from Tesla, BYD, Zeekr, NIO, XPeng, and newer performance-oriented domestic brands. Xiaomi’s revised SU7 strengthens its hand in several areas:
- Value positioning: still aggressive even after a RMB 10,000-14,000 pre-sale increase versus the outgoing model
- ADAS competitiveness: full-line lidar and 700 TOPS narrow the hardware gap versus more expensive rivals
- Energy efficiency and charging: the 752V/897V shift improves real-world usability
- Safety narrative: more airbags and stronger structural hardware help Xiaomi counter skepticism often aimed at newer entrants
The one caveat is that pre-sale pricing does not always equal final transaction pricing. AutoHome notes the final launch price could still change when the car officially reaches the market in April.
What to Watch Next
Several questions will determine how successful this upgrade cycle becomes:
- Will Xiaomi keep the pre-sale pricing intact at launch, or trim it further?
- Can the company deliver the promised charging performance consistently across China’s charging network?
- How quickly will Xiaomi HAD mature in real-world urban and highway use?
- Will the 902 km CLTC SU7 Pro translate into convincingly strong real-world efficiency?
- Can Xiaomi maintain delivery momentum while offering upgrade paths to earlier locked-in customers?
For now, the updated SU7 looks less like a routine refresh and more like a statement of intent. Xiaomi is signaling that it does not want to compete only as a tech brand making cars. It wants to be judged as a full-spectrum EV manufacturer — on platform voltage, safety engineering, braking, suspension, assisted driving, and everyday usability.
If the April launch delivers on these claims, the 2026 Xiaomi SU7 could become one of the most consequential upgrades yet in China’s electric sedan market.
