Will XiaoMi's N90 Max Redefine SUV Space Flexibility?

On August 21, 2026, the 29th Chengdu International Auto Show commenced at the Western China International Expo City. XiaoMi Auto showcased its entire lineup at Hall 10, Booth H1004.

Among the featured vehicles were the XiaoMi PengCheng series models — N90 Max and N70 Max, both range-extended SUVs, which made their public debut after starting pre-sales in July. The stand also featured the SU7 Ultra in Lightning Yellow, the new-generation SU7 in Indigo Stone Green, and the YU7 in Flowing Gold Pink.


The N90 Max is XiaoMi Auto’s initial foray into the range-extended market, positioned as a “Grand Seven-Seat Flagship Range-Extended SUV.” It measures 5285 mm in length and has a wheelbase of 3080 mm, built on the XiaoMi Kunlun platform specifically developed for range-extended models. The design focuses on multi-person family travel scenarios from chassis architecture to spatial layout.

The XiaoMi Kunlun platform is crafted around three core capabilities: flat flooring, square layout, and extra-long sliding rails. The flat flooring is the most visible highlight: by integrating a high-efficiency coaxial electric drive, the position of the electric drive’s floor thickness is reduced by 145 mm. The flat-design large battery pack further thins the thickness by 180 mm. With a clever placement of a 60L large fuel tank between the battery and electric drive, a completely flat floor extends from the cockpit to the trunk, nearly 3 meters long, with an angle of just 2.95 degrees and thickness controlled at 298 mm. This allows second- and third-row passengers to enjoy flat foot space, eliminating the common issue of central bulges in traditional range-extended SUVs.

Concerning spatial flexibility, the XiaoMi Kunlun platform comes equipped with up to six sliding rails, with the N90 Max’s slides reaching a maximum length of 1938 mm. Both the second and third rows have 900 mm of sliding travel, made of 7-series enhanced aluminum alloy, with a locking strength of 54000N, and have passed 15000 cycle tests without loosening. The second-row seat can shift backward to provide up to 1550 mm of space, comparable to an MPV experience; when moved fully forward, the trunk expands to a maximum capacity of 1831L, catering to long-distance travel loading needs.

In addition to the headline-making PengCheng series, the stand also featured models such as the SU7 Ultra in Lightning Yellow, the new-generation SU7 in Indigo Stone Green, and the YU7 in Flowing Gold Pink, with the XiaoMi Customized Service YU7 GT Samurai Black Matte making its exhibition debut.

XiaoMi Customized Service YU7 GT Samurai Black Matte uses a black paste base, overlaid with a black pearlescent layer, and incorporates special transparent glass flakes, subtly glinting like blade light under the moon; finally, it is coated with a matte finish varnish to reduce reflection, leaving a texture as delicate as black jade, warm to touch and stark to the eye.The Xiaomi Pengcheng series is expected to officially launch in September. From fully electric models to range-extended SUVs, Xiaomi Motors is aiming to reach a broader range of family users with a more comprehensive product lineup. The delivery experience and reputation of 500,000 units accumulated by the SU7 series will also provide strong support for the market performance of the Xiaomi Pengcheng series.
