What is the 'seven-car stacking' challenge for the Xiaomi HyperEngine N90 Max? How does it relate to everyday driving scenarios?
Official answer
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. Ultimately, under such immense pressure, the occupant cabin structure of the bottom N90 Max remained intact, the A/B/C/D pillars showed no obvious deformation, and all four doors could be opened and closed normally, making the challenge a success.
