Xiaomi clarified that the Pengcheng series does not require emptying the trunk to activate the face-to-face seating mode. Users must ensure items do not block the rear seat rail path, as indicated by voice prompts. The cabin space and trunk capacity vary by model: the N70 series offers 662L of trunk space, the N90 Max provides 480L, and the N90 Max Exploration Edition features 773L.

The company confirmed that front rotating seats and front zero-gravity seats are mutually exclusive options. The rotating seat package is priced at ¥18 000, with a free promotion available until October 7, 2024. The zero-gravity seat option also costs ¥18 000, with a promotional price of ¥3 000 until the same date. Rotating seats are standard on the N90 Max Exploration Edition.

Safety protocols dictate that the rotating seat function is restricted to P-gear parking mode only. Additionally, the entire Pengcheng lineup supports optional electric welcome pedals with a maximum load capacity of 200kg. The N70 Pro, N70 Max, and N90 Max models are equipped with 12 ecological expansion interfaces, including support for roof rack installation.

The Kunlun technical architecture allows for flexible seat positioning via flat floors and long rails. Users can adjust seat placement to prioritize either social space or storage capacity and save these configurations as custom presets. This design aims to provide adaptable interior layouts for various scenarios, including camping, business meetings, or daily commuting.
