Xiaomi used its second major automotive technology event in Beijing on July 30, 2026 to do more than reveal two new SUVs. The company launched the Kunlun architecture, its first platform for extended-range electric vehicles (EREVs), and opened pre-sales for the Xiaomi Pengcheng N70 Max and N90 Max at RMB 259,900 and RMB 299,900 respectively, ahead of a formal market launch in September 2026. For Xiaomi, this marks a strategic expansion beyond battery EVs like the SU7 and YU7 into China’s highest-volume family SUV segment—while trying to answer lingering questions around safety, technology sourcing, and brand credibility.
Xiaomi’s Bigger Move: Not Just New SUVs, but a New Platform
The headline products were the new Pengcheng SUVs, but the deeper story was the debut of the Kunlun technology architecture. Unlike Xiaomi’s earlier Modena platform, which underpins its pure-electric models, Kunlun is designed for all future Xiaomi vehicles that include a fuel tank.
According to Xiaomi, Kunlun has three pillars:
- Vehicle platform
- Super extended-range system
- Full-domain safety
This matters because the company is no longer playing only in the sedan and BEV space. With Kunlun, Xiaomi is targeting the large family SUV market dominated by Li Auto, Aito, and increasingly other Chinese EREV and plug-in hybrid players.
Why Xiaomi Flattened the Floor
One of the most technically interesting parts of the presentation focused on cabin packaging rather than headline acceleration or screen count. Xiaomi said its research into owners of large “9-series” SUVs found a common complaint: vehicles may be physically large, but their interior layouts waste space.
Xiaomi’s solution was to redesign the underfloor structure to create a flatter, more usable interior floor.
Key engineering changes included:
- Rear electric drive switched to a coaxial layout
- Power electronics moved forward, lowering the floor above the e-drive by 145 mm
- Battery control modules relocated from beneath the second row to the front and rear of the vehicle
- Another 180 mm of floor height reduction in that area
- A 60-liter fuel tank integrated into the freed-up space
Xiaomi claims the floor and related structure are about 200 mm thinner than comparable same-size SUVs, with that space effectively “given back” to passengers.
For buyers in China’s three-row SUV market, this is not a trivial detail. Third-row legroom, aisle usability, luggage capacity, and flat-fold practicality often determine whether a car works as a true one-car family solution.
The First Xiaomi Extended-Range Powertrain
The Pengcheng lineup is also Xiaomi Auto’s first serious entry into the EREV segment. That alone is notable, because Xiaomi had previously indicated it had no near-term plans to sell range-extended vehicles.
Lei Jun framed Xiaomi’s approach as a “large-battery extended-range” strategy rather than a conventional compromise. The company’s core claims are strong on paper:
- Pure electric range: up to 505 km
- Combined range: up to 1,705 km
- Fuel consumption in charge-sustaining mode: 6.26 L/100 km
- Fuel requirement: supports 92 RON gasoline
The range-extender itself is a 1.5-liter unit with 42% thermal efficiency, which Xiaomi said was developed on the basis of a mature existing engine and then customized for its needs. Xiaomi stated that seven core components were re-selected and redeveloped, accounting for nearly half of the total power unit cost.
Xiaomi’s wording shift: from “self-developed” to “customized”
An important nuance in this launch was Xiaomi’s language. In its EV program, Xiaomi has often emphasized in-house development—especially around e-motors and smart systems. Here, however, the company was more careful.
For the range extender, Xiaomi said the engine was customized by Dong’an Power to Xiaomi’s requirements. On the battery side, Xiaomi described its role as:
- Product definition
- Battery pack design leadership
- Deep participation in cell design and development
- Full-process quality control
That is not the same as vertically integrating engine or cell production. In practical terms, this is a realistic decision: developing a combustion engine from scratch within a compressed automotive startup timeline would be extremely difficult. But strategically, it also signals that Xiaomi is becoming more supplier-integrated and pragmatic as it scales.
Pre-Sale Prices and Core Vehicle Specs
The two launch models target slightly different family use cases.
| Model | Seating | Pre-sale price | Launch timing | Key positioning |
|---|---|---|---|---|
| Xiaomi Pengcheng N70 Max | 5 seats | RMB 259,900 | September 2026 | Large five-seat family SUV |
| Xiaomi Pengcheng N90 Max | 7 seats | RMB 299,900 | September 2026 | Flagship three-row family SUV |
Xiaomi compared the N90 Max in size class to vehicles like the Li Auto L9 and Aito M9, placing it squarely in one of China’s most competitive premium-new-energy segments.
The cabin concept is built around what Xiaomi calls an “intelligent variable large space.” The idea is to turn the SUV into a mobile room that can switch between commuting, work, rest, and family entertainment modes.
Highlighted interior features include:
- 18 configurable cabin scenarios
- Modes for face-to-face seating, mobile office, and bed-like resting layouts
- Seat rails enabling significant fore-aft flexibility
- Third-generation Snapdragon 8 cockpit platform
This “living space on wheels” approach aligns closely with current Chinese family SUV trends, where buyers increasingly evaluate vehicles not just as transportation, but as multi-scene lifestyle products.
Assisted Driving: Big Hardware Numbers, Measured Messaging
On smart driving, Xiaomi gave buyers a strong hardware package as standard.
Xiaomi Pengcheng AD hardware
- Xiaomi HAD driver assistance standard across the range
- Nvidia Thor in-car computing platform
- 700 TOPS computing power
- Dual LiDAR
- 4D millimeter-wave radar
- Rear solid-state LiDAR on the N90 Max
That rear-facing LiDAR is especially interesting. Xiaomi says it is designed around the real-world habits of EREV family SUV owners, particularly frequent reversing, tight parking, and rear blind-spot scenarios. One cited figure from related coverage put measurement precision at 2 cm.
Yet just as notable as what Xiaomi said is what it did not emphasize. The presentation reportedly did not dwell on AEB in detail, despite advanced driver assistance being a highly sensitive issue for public trust and regulation in China. Instead, Xiaomi leaned on hardware specification, usage statistics, and a brief mention that its upgraded XLA end-to-end perception model has been receiving better user feedback.
This suggests Xiaomi is being cautious: sell capability, but avoid overpromising autonomy in an environment where both regulators and consumers are scrutinizing ADAS claims more closely.
Safety Was the Real Theme of the Night
If there was one message repeated throughout the event, it was safety. Lei Jun reportedly returned to the phrase “safety above all” multiple times.
That emphasis was not accidental. Xiaomi Auto has faced public debate over issues including:
- Battery fire concerns
- Door-related incident narratives
- ADAS and AEB scrutiny
In response, Xiaomi presented a stack of battery and chassis safety claims.
Key safety claims from the launch
- Battery tested under 55°C, full state of charge, and single-cell thermal runaway worst-case conditions
- Target outcome: no thermal propagation, no fire, no explosion
- Underbody protection rated to 500 joules, versus a cited new national standard of 150 joules
- Xiaomi also said the battery pack should remain functionally intact after a crash
The presentation’s most dramatic proof point was a video showing a fully loaded seven-seat vehicle at 160 km/h suffering two left-side tire blowouts simultaneously, while maintaining straight-line stability.
Whatever viewers thought of the production values, it was effective messaging. In a launch full of numbers, this was the moment that appears to have landed emotionally with the audience.
Xiaomi also disclosed testing scale for the architecture:
- 566 test vehicles投入 by June 30, 2026
- 4.28 million km of accumulated road testing
Those numbers are substantial for a relatively young carmaker, though the true industry benchmark will be how the vehicles perform in customer hands after launch.
Xiaomi’s Auto Business Is Growing Fast
Another major data point from the event was Xiaomi’s latest delivery figure. Lei Jun said cumulative deliveries of the SU7 and YU7 have exceeded 700,000 units.
That is a remarkable number given the brand’s short time in the automotive market and helps explain why Xiaomi now has the confidence to branch into EREV SUVs.
The strategy is logical:
- Build attention and brand momentum with sporty BEVs
- Establish delivery scale and ecosystem stickiness
- Expand into the largest-volume family SUV categories in China
In short, Xiaomi is no longer just proving it can build a car. It is now trying to prove it can build a portfolio.

Competitive Context: Xiaomi Enters China’s Hardest EV Battleground
The move into EREVs puts Xiaomi into one of the fiercest parts of the Chinese EV market.
Its key rivals now include:
- Li Auto, which built its success on family-focused range-extended SUVs
- Aito (Huawei-backed), especially the M9 in the large premium segment
- Emerging offerings from brands such as Zeekr, Leapmotor, and other Chinese groups blending EV, EREV, and PHEV strategies
What Xiaomi appears to be betting on is a combination of:
- More emotionally resonant brand power than many traditional automakers
- Strong smart-cabin and consumer-electronics integration
- Competitive ADAS hardware
- Better packaging and space storytelling
- Aggressive pricing relative to segment expectations
At RMB 259,900-299,900, the Pengcheng range looks positioned to undercut some higher-end family SUV rivals while still feeling premium enough for upwardly mobile urban buyers.
Why This Matters Globally
Xiaomi’s Kunlun launch says something bigger about the Chinese EV market in 2026.
1. EREV is not a transitional niche anymore
What was once viewed by some as a stopgap technology is now central to market competition in China, particularly in larger SUVs. Even a brand built on pure EV credibility now sees range extension as essential.
2. Chinese EV competition is becoming architecture-led
Success is no longer just about battery size or touchscreen count. Packaging efficiency, software stack integration, and platform flexibility are becoming more important.
3. Supplier ecosystems are shaping winners
Xiaomi’s careful use of “customized” instead of “self-developed” shows how modern Chinese EV makers increasingly combine in-house control with specialized supplier execution.
4. Safety messaging is becoming a front-line battlefield
As China’s EV market matures, brands can no longer rely on novelty alone. Safety validation, testing transparency, and credibility in ADAS communication are becoming decisive brand assets.
The Broader Tech Backdrop
The launch also arrived amid a wider Chinese tech and mobility news cycle that underlines how fast the sector is converging.
On the same day:
- Li Auto announced OTA 9.1, adding ADAS “style selection,” non-marked parking support, active repositioning, and narrow obstacle pass assistance
- Huawei Qiankun expanded into the joint-venture premium segment via Chery Jaguar Land Rover’s Freelander 8
- Autonomous driving company DeepRoute.ai reportedly set up a new lab to pursue foundation models and world models
The implication is clear: the battle among Chinese EV brands is no longer confined to drivetrain choice. It increasingly spans AI models, cockpit silicon, ADAS stacks, supplier alliances, and even robotics-adjacent software capabilities.
Outlook: Can Xiaomi Turn Momentum Into Segment Leadership?
Xiaomi’s latest launch was ambitious and carefully staged. The company is trying to do three things at once: enter the EREV mainstream, defend its technology narrative, and rebuild trust around safety. On paper, the Pengcheng N70 Max and N90 Max check many of the right boxes—range, price, cabin flexibility, and serious ADAS hardware.
The real test starts next. When deliveries begin after the September 2026 launch, Xiaomi will need to prove that its Kunlun architecture can deliver not just viral presentations and impressive specification sheets, but also the reliability, efficiency, and safety consistency expected in China’s brutally competitive family SUV market.
If it can, Xiaomi may become something even more significant than a successful EV startup: a full-spectrum Chinese new-energy carmaker capable of competing across both BEV and EREV categories at scale.
