画面里，N90 Max的座椅被固定上两条拖拽绳索，车辆在湿滑路面上向前牵引。一端是55吨的矿卡，另一端还连着一台N90 Max，实际牵引总质量达到57.8吨。小米澎程与徐工集团发布的视频显示，挑战结束后，座椅滑轨仍可正常调节。
In the footage, two tow ropes are attached to the N90 Max's seats as the vehicle moves forward on a wet, slippery surface. At one end is a 55-tonne mining truck, while the other is connected to another N90 Max, bringing the actual total towing mass to 57.8 tonnes. A video released by Xiaomi Pengcheng and XCMG Group shows that the seat rails remained fully adjustable after the challenge.
这不是把车钩到外部牵引装置上，而是把拉力施加到座椅及其滑轨结构上。小米汽车副总裁李肖爽驾车完成牵引，随后通过语音让座椅向前移动，滑轨继续工作。这个动作把一个平时负责调节第二、三排座椅的位置部件，放到了远超日常场景的负载条件下。
This was not a case of hooking the vehicle up to an external towing device; instead, the pulling force was applied to the seats and their rail structure. Xiaomi Auto vice president Li Xiaoshuang completed the tow, then used a voice command to move the seat forward, with the rails continuing to function. The demonstration subjected a component normally responsible for adjusting the position of the second- and third-row seats to loads far beyond those encountered in everyday use.
N90 Max的滑轨采用7系加强铝合金。小米澎程称，这种材料的抗拉强度较普通7系铝合金提升9%，滑轨锁止强度达到54000N，剥离强度最高为57000N；在-20°C至60°C环境下，滑轨完成了15000次循环滑动测试，测试后没有松动和异响。车辆共有6根滑轨，最长达到1938mm，支持前后排座椅滑移和多种座舱布局。
The N90 Max's rails use reinforced 7-series aluminum alloy. Xiaomi Pengcheng says the material's tensile strength is 9% higher than that of standard 7-series aluminum alloy, while the rails have a locking strength of 54000N and a maximum peel strength of 57000N. In temperatures ranging from -20°C to 60°C, the rails completed 15,000 cycles of sliding tests, with no loosening or abnormal noise afterward. The vehicle has six rails, the longest measuring 1938mm, supporting front- and rear-seat sliding and multiple cabin layouts.
具体来说，这次挑战给家庭用户带来的不是“能拖矿卡”的日常能力，而是对座椅活动部件可靠性余量的一次直观展示。座椅滑轨需要频繁承受调节、锁止和乘坐过程中的载荷，极限牵引至少说明厂方愿意把结构强度拿到公开视频中验证；但挑战结果不能替代长期道路使用数据，现有数字也主要来自小米澎程，尚未见独立试验结果。
More specifically, the challenge does not demonstrate a daily capability for family users to tow a mining truck. Instead, it offers a visual demonstration of the reliability margin of the movable seat components. Seat rails must regularly withstand loads from adjustment, locking and passengers sitting down. The extreme towing test at least shows that the manufacturer was willing to validate the structure's strength in a publicly released video; however, the result cannot replace long-term road-use data, and the figures currently available mainly come from Xiaomi Pengcheng, with no independent test results reported so far.
N90 Max定位为大七座旗舰增程SUV，采用1.5T增程系统和双电机四驱，峰值功率为310kW，搭载76kWh三元锂电池，CLTC纯电续航464km、综合续航1705km，预售价29.99万元，计划于9月上市。对于这款仍在上市前阶段的车型，滑轨测试把“可变空间”背后的机械基础提前摆到了消费者面前。
The N90 Max is positioned as a large seven-seat flagship range-extended SUV. It uses a 1.5T range-extender system and dual-motor all-wheel drive, with a peak output of 310kW and a 76kWh ternary lithium battery. It offers a CLTC pure-electric range of 464km and a combined range of 1705km. The presale price is 299,900 yuan, and the vehicle is scheduled to launch in September. For a model that remains in the pre-launch stage, the rail test has brought the mechanical foundation behind its variable cabin space into view for consumers.
