Xiaomi Pengcheng N90 Max Optimizes Space with Kunlun Platform, Offering Multiple Storage Modes and Seat Functions

The Xiaomi Pengcheng N90 Max, built on Xiaomi’s Kunlun platform, significantly reduces third-row space intrusion by the wheel arches and enhances lateral cabin room through several optimizations: separating spring and damper layouts, relocating dampers outward, adopting a reduced caster angle, and contouring rear air ducts to match the curvature of the wheel arches. The third-row shoulder width measures 1,440 mm and hip width 1,276 mm—nearly 200 mm wider than the segment average. Headroom reaches 962 mm, with seated height at 890 mm, comfortably accommodating three passengers each 1.8 meters tall. Additionally, the third-row seats can slide rearward by 180 mm from their standard position, further expanding legroom without compromising second-row space. The vehicle offers three trunk storage configurations: - **Standard Mode**: 577 L capacity, fitting seven 20-inch suitcases—ideal for daily seven-passenger use. - **Convenient Mode**: Expands to 1,351 L by sliding forward and folding the third-row seat cushions, suiting four-passenger long-distance trips and accommodating up to nine suitcases of varying sizes. - **Max Storage Mode**: Reaches a maximum of 1,831 L with both second and third rows slid forward and seat cushions folded, enabling storage of up to 18 suitcases or two 700C road bikes (front wheels intact). Regarding seat rotation functionality, the N90 Max features a face-to-face seating layout between the first and second rows. This arrangement facilitates easy entry and exit via the rear doors, complemented by an approximately 90° rear door opening angle and generous ingress space. A sliding center console moves between the first and second rows, pairing with an ecosystem-compatible table to create a four-person coffee table setup. The second-row seats feature extra-long sliding rails, allowing natural leg extension even in the face-to-face configuration. Moreover, this layout eliminates the need to frequently move items stored in the third row. For driving safety, the seat rotation function is only enabled when the vehicle is in Park (P) mode. All seat rotation mechanisms underwent 5,500 durability cycles across temperatures ranging from -20°C to 60°C, ensuring reliable operation without loosening. Seat sliders utilize 7-series reinforced aluminum alloy, offering 9% higher tensile strength than standard 7-series aluminum; on the N90 Max, slider peel strength reaches up to 57,000 N. Additionally, the sliders completed 15,000 cycle tests within the same temperature range, verifying long-term reliability and stability.
