Xiaomi Pengcheng N90 Max Unveiled: High-Strength Body Structure and Rigorous Crash Test Standards Revealed

At its technology launch event, Xiaomi unveiled detailed safety specifications for its new vehicle, the Pengcheng N90 Max. The car features an armored cage-type body structure, with high-strength steel and aluminum alloys accounting for 90.4% of the body materials. Sixteen critical areas of the body are reinforced with ultra-high-strength steel boasting a tensile strength of 2,200 MPa. Additionally, the vehicle is equipped with an extra-large, one-piece hot-formed door ring measuring 3.3 meters in length and 1.5 meters in height, spanning from the first to the third row of seats and covering the A, B, C, and D pillars. Four key sections of this door ring are also strengthened with 2,200 MPa ultra-high-strength steel. Compared to conventional welding techniques, this structural design increases the body’s load-bearing capacity during side pole impacts by 19%. Moreover, Xiaomi stated that it conducted multiple omnidirectional crash tests on the entire vehicle, all performed at speeds exceeding current industry standards: - Frontal crash test speed: 64 km/h (C-NCAP standard: 56 km/h) - 25% small overlap frontal crash test speed: 72 km/h (China Insurance Automotive Safety Institute standard: 64 km/h) - Side impact test speed: 70 km/h (C-NCAP standard: 60 km/h) - Rear-end collision test speed: 92 km/h (new national standard requirement: 50 km/h)
