When Xiaomi EV introduced the all-new SkyNomad Series—comprising the flagship 7-seater SkyNomad N90 Max and the 5-seater AWD SkyNomad N70 Max—the highlight wasn’t just its reconfigurable interior or 1,700+ km extended-range capabilities. Beneath its versatile design lies Xiaomi Kunlun Total Safety, a holistic, multi-layered security architecture designed to set a new benchmark for occupant and battery protection in large family vehicles.
Built upon the brand-new Xiaomi Kunlun Platform, the safety architecture approaches protection from every angle: structural integrity, intelligent restraint systems, chemical and thermal battery isolation, and emergency escape engineering.
Structural Architecture: The 2,200 MPa Armor Cage
At the heart of the N90 and N70 safety structure is an ultra-high-strength steel-and-aluminum hybrid body. High-strength steel and aluminum alloy account for 90.4% of the SkyNomad N90 Max body frame, utilizing 2,200 MPa ultra-high-strength steel across 16 critical load-bearing locations.
Key structural breakthroughs include:
- 14-Ton Roof Crush Resistance: An embedded 2,200 MPa roll cage running continuously from the A-pillar to the C-pillar enables the vehicle to withstand a roof-crush load of nearly 14 tons. This structure boosts A-pillar load capacity by 24%, providing vital protection in truck underride scenarios.
- 13-in-1 Hot-Formed Door Ring: Spanning the A, B, C, and D pillars, this single-piece hot-formed ring secures protection across all three seating rows, increasing side-impact load capacity by 19%. All four doors are further reinforced with 2,200 MPa anti-collision beams and rear-door anti-detachment hooks.
- Monolithic Front Floor Frame: A 2,000 MPa laser-welded, single-stamped front floor frame featuring 2,200 MPa local reinforcements improves occupant survival space by 9% in frontal impacts and 10% in side-pole impacts, creating a protective vault for both the cabin occupants and the underfloor battery pack.
All-Seat Airbag Network and Cabin Health
Safety engineering on the Kunlun Platform extends equal priority to every row, departing from industry standards that often prioritize front-seat protection.
- Class-Leading 12 Airbag System: The N90 Max comes standard with 12 airbags covering all three rows.
- Targeted Far-Side Protection: The front cabin features 4-point-mounted far-side airbags (reducing driver head displacement by 24%), while the second row includes dual-chamber far-side airbags that reduce head displacement for left-side occupants by 34%.
- Full-Length Curtain & 3rd-Row Airbags: A 3,200 mm side curtain works in tandem with dedicated third-row side airbags to cover the head, chest, and waist of rear occupants, reducing shoulder compression by 44% and rib compression by an average of 18% during side impacts.
- Advanced Collision Sensing: Nine specialized collision sensors—including additional front and C-pillar units—ensure precise deployment timing during complex crash dynamics, such as center-pole collisions and rear-side impacts.
- Infant-Grade Interior Materials: Safety also includes environmental health. The entire 32 m² soft-wrapped cabin carries OEKO-TEX® certification, ensuring zero harmful substance migration or allergen risk for infants. Additionally, 39 anti-pinch points across windows, electric doors, and seat mechanisms cap pinch forces under 150 N.
Xiaomi Armor Scale Battery Safety
Integrating large extended-range battery packs (up to 76 kWh) demands extreme structural and thermal isolation. The Xiaomi Armor Scale Battery package incorporates two major defense barriers:
- 18-Layer Structural Defense: Designed to withstand direct underbody impacts up to 500 Joules without fluid leakage, fire, or cell deformation.
- 16-Layer Thermal Insulation: Utilizing high-grade aerogel insulation materials, the thermal management system prevents cascading cell-to-cell thermal propagation. Even during a full-charge single-cell thermal runaway test at 55°C ambient temperature, the pack maintains complete thermal stability without fire or explosion.
Furthermore, direct oversight during cell chemistry design has reduced battery health degradation by 50%, doubling the service cycle life compared to national baseline standards.
Submersion, Power-Loss, and Emergency Egress
Recognizing that real-world emergencies can extend beyond crash dynamics, the Kunlun safety system incorporates multi-point redundant escape features:
- Triple-Redundant Door Unlocking: In the event of total vehicle electrical failure, all doors feature independent mechanical releases both internally and externally.
- Dual Tailgate Escape Pulls: The SkyNomad is the only large SUV in its class to equip dual mechanical emergency release handles inside the tailgate, allowing third-row passengers to exit through the rear trunk without climbing over folded seats.
- 750 mm Wading & 3-Minute Emergency Floating: Sealed critical components give the vehicle an official 750 mm emergency wading depth. In accidental deep-water submersion scenarios, the sealed architecture provides an emergency floating window that keeps the cabin free of significant water ingress for up to 3 minutes, giving occupants crucial time to evacuate.
Conclusion
With the SkyNomad N90 Max and N70 Max, Xiaomi’s Kunlun architecture demonstrates that spatial flexibility and family convenience do not require compromising structural integrity. By combining ultra-high-strength hot-formed steel cage designs, equal-opportunity airbag coverage across all three rows, robust thermal battery protection, and mechanical egress redundancies, the Kunlun safety system provides a rigorous, all-scenario security foundation for modern electric mobility.
