This test is commonly referred to in the industry as a roof crush test. It is primarily used to evaluate a vehicle's roof load-bearing capacity and to verify how well the body structure protects occupants in extreme scenarios such as rollovers or heavy objects falling onto the roof.
In the roof crush challenge demonstrated by the Xiaomi HyperEngine N90 Max, seven N90 Max vehicles were stacked vertically. The bottom N90 Max bore the weight of six other N90 Max vehicles, totaling 17 tons. Ultimate…
First, it benefits from the high-strength materials of the N90 Max's armored cage body, where high-strength steel and aluminum alloy account for up to 90.4%, ensuring sufficiently high overall body strength. Sixteen applications of 2200MPa Xiaomi super-strong steel are used throughout the vehicle, further enhancing the strength of key positions in the occupant cabin.
There is also the high-strength body structure. The N90 Max is equipped with a 2200MPa "built-in roll cage," which embeds gas-expa…
The core purpose of this roof crush challenge was to test body strength. Following professional roof crush testing standards, we set up fixed supports under the door sills of the bottom N90 Max to eliminate other influencing factors and concentrate all the pressure applied from above onto the body structure, which is why the suspension and tires were not compressed.
Specifically: beneath the left and right sill beams of the bottom N90 Max, we placed I-beams measuring 1795mm long, 250mm high, and…
After the launch of the Xiaomi HyperEngine series, multiple media outlets including Dongchedi, Autohome, and Yiche conducted real-world tests on the range and energy consumption performance that users care about most. Here is a brief report organized by model and test conditions:
N70 Max:
On September 8, @Autohome conducted a range challenge from Beijing to Shanghai without charging or refueling along the way. At an average speed of 95.7km/h, it traveled 1099.3km with a displayed fuel consumptio…
