Disposal EVs? Xiaomi's "Aluminum Replacement" Isn't What You Think
Viral videos claiming that Xiaomi has "replaced aluminum" with a new metal sound like the start of a materials revolution. The reality is more nuanced and, in some ways, more disruptive than the headline suggests. A close look at the 2026 Xiaomi SU7 and SU7 Ultra shows a blend of genuine engineering innovation, aggressive factory design, and YouTube-friendly exaggeration.

China's INSANE Technology Just Replaced Aluminum! XIAOMI CHASSIS 2026
But -
Where the video comes closer to reality is in its description of Xiaomi's 9100-ton "Hypercasting" cluster. This system replaces roughly 72 stamped and welded components with a single integrated die-cast rear structure. Tesla pioneered this idea with its Gigacasting, but Xiaomi's 2026 implementation uses higher clamping force and a more complex integration of functions into one casting...
On the repair side, the story flips. Because the rear chassis is a single, massive casting, even a moderate rear-end collision can render the car a total loss. The structure cannot be easily straightened, sectioned, or replaced in modules. Insurers in 2026 are already responding with higher premiums for hypercast vehicles, echoing similar concerns seen with Tesla's large castings.
Critics warn that this could distort the used EV market: vehicles that are brilliant when new may have little or no resale value if their structural "spine" is damaged or simply deemed uneconomical to repair.
