小米汽车详解澎程N90 Max"七车叠罗汉"挑战 验证顶压与续航性能

小米汽车在第287集答网友问中介绍了澎程N90 Max的"七车叠罗汉"顶压测试结果1。在该测试中，最下方的N90 Max承受了6台车共17吨的顶部重压，车辆乘员舱结构保持完好，四个车门仍可正常开关1。

这一出色表现源于车辆的结构设计。澎程N90 Max采用高强度钢和铝合金，占比高达90.4%1，全车应用16处2200MPa小米超强钢1。车辆配备的2200MPa"内嵌式防滚架"长度达到2510mm1，而一体式热成型门环尺寸达到3289mm长、1556mm高，覆盖A、B、C、D柱1。

同时小米汽车发布了多家媒体对N70 Max和N90 Max系列的续航实测成绩1。汽车之家的北京到上海续航挑战中，N70 Max行驶1099.3km，表显油耗5.7L/100km1；N90 Max行驶1260.6km，表显油耗5.9L/100km1。大鹏快开车的24小时零补能挑战中，N90 Max在28小时14分钟内总计行驶1600km1。此外，澎程N90 Max的增程器在首保后3年或3万公里才需保养1次，仅需加92号汽油1。

Xiaomi Automobile detailed the structural capabilities of the Peng Cheng N90 Max in its 287th episode of viewer Q&A, showcasing a rooftop pressure test in which the bottommost vehicle withstood a combined weight of 17 tons from six stacked cars above it, with the passenger cabin structure remaining intact and all four doors functioning normally 1. The vehicle's resilience stems from its extensive use of high-strength materials, with high-strength steel and aluminum alloy accounting for 90.4% of the overall composition, including 16 applications of 2200 MPa ultra-high-strength steel throughout the body 1. The car features a 2200 MPa "embedded roll cage" measuring 2,510 mm in length and an integrated one-piece hot-formed door frame spanning 3,289 mm in length and 1,556 mm in height, covering all four pillars (A, B, C, and D) 1.

The company simultaneously released real-world fuel consumption data from multiple media outlets testing both the N70 Max and N90 Max models 1. In a Beijing-to-Shanghai range challenge conducted by Autohome, the N70 Max achieved 1,099.3 km of travel with a displayed fuel consumption of 5.7 liters per 100 kilometers, while the N90 Max covered 1,260.6 km at 5.9 liters per 100 kilometers 1. The N90 Max also completed Dapeng Quick Drive's 24-hour zero-refueling challenge, traveling 1,425 km over approximately 28 hours and 14 minutes, with a total distance of 1,600 km 1. Additionally, the vehicle's range extender requires servicing only once every three years or 30,000 kilometers following the initial maintenance and operates exclusively on 92-octane gasoline 1.
