Xiaomi turned the new SU7 teardown into China’s biggest car conversation this week

Chinese auto news usually goes viral for familiar reasons: a price war, a crash, a celebrity founder quote or an explosive delivery number. Xiaomi chose a different trigger. In an official April 2 post, the company said Lei Jun would spend five hours tearing down a new SU7 live, with experts on hand to explain the car from paint and trim to body safety, chassis and battery protection.

That matters because the teardown was not framed as a hidden laboratory demo. Xiaomi turned it into appointment viewing. The company effectively said: if the market is already arguing about the new SU7, then let the discussion happen around the actual hardware. For a Chinese EV brand under intense attention, that is a high-confidence move. It also explains why the story spread far beyond normal launch coverage.

Xiaomi’s own product page already framed the new-generation SU7 as more than a cosmetic refresh, but the official parameter table and configurator make the lineup easier to read. The base SU7 anchors the range at 219,900 yuan with 720 km CLTC, SU7 Pro stretches to 902 km CLTC at 249,900 yuan, and SU7 Max becomes the performance flagship at 303,900 yuan with 508 kW and a 3.08-second 0-100 km/h claim.

That matters because the teardown story now sits next to a fully official explanation of how Xiaomi wants buyers to choose the car. The company is not only talking about one headline number. It is showing a trim ladder with clear trade-offs in battery size, charging speed, wheels, brakes and straight-line pace.

The Xiaomi configurator is where the viral teardown story turns into a practical buying guide. Official comparison data shows SU7 Pro as the clear long-range sweet spot, SU7 Max as the faster and more heavily equipped flagship, and the base SU7 as the entry point that keeps the brand’s price case intact.

Just as important, Xiaomi’s own compare tool does not hide the hardware split. Wheel-and-tire packages, braking equipment, battery size and charging time all move in a way that makes the three trims feel deliberately separated rather than lightly re-badged.

The most revealing part of Xiaomi’s official SU7 page is how much space it devotes to structural and battery safety. Xiaomi says the car uses a steel-aluminum mixed body, 2200 MPa high-strength steel in the four side-impact beams and a 2200 MPa embedded anti-roll structure running from the A-pillar through the C-pillar. The company also says every version now carries nine airbags, adding rear side airbags to the package.

Battery protection is described in equally explicit terms. Xiaomi claims as many as 17 layers of high-voltage insulation protection, compliance beyond the latest thermal-runaway safety standard, a new underbody anti-ballistic coating and an additional 1500 MPa anti-scrape crossmember at the front of the chassis. Whether readers view this as engineering confidence or marketing theater, it is exactly the sort of detail that kept the discussion alive after the stream ended.

Xiaomi’s official follow-up explains why the teardown stayed commercially relevant after the stream finished. On March 31, the company said March deliveries had topped 20,000 vehicles and that cumulative deliveries of the new-generation SU7 had exceeded 7,000 units since March 23. That meant the public engineering show was happening while real customer demand was already building.

Then came the second official beat. On April 7, Xiaomi published a reassembly video, said the stripped SU7 was put back together in about seven hours and stressed that the car would remain a display and internal-test vehicle rather than being sold. That helped preserve the story’s credibility: the teardown was treated as a real engineering exercise, not as a disposable publicity prop.
