Xiaomi’s Lei Jun Delivers a Deep Dive into the SU7: A Three-Hour Live Teardown That’s Turning Heads

In an unprecedented move that blurred the lines between tech launch and automotive masterclass, Xiaomi founder Lei Jun recently took to the stage—well, the factory floor—for a marathon livestream that stretched over three hours, all centered around the company’s latest automotive venture: the SU7 sedan. Broadcasting live from Xiaomi’s state-of-the-art auto factory in Beijing’s Yizhuang district, Lei Jun didn’t just showcase the car—he tore it down piece by piece, offering enthusiasts and potential buyers an unprecedented look under the hood, inside the cabin, and into the very DNA of Xiaomi’s first mass-market electric vehicle.

The livestream, which quickly became a trending topic across Chinese social media platforms, was more than a marketing stunt. It was a transparent, almost surgical dissection of the SU7, with Lei Jun joined by automotive safety expert Zhu Xichan. Together, they walked viewers through every major component, leaving no bolt unturned. From the sleek, aerodynamic exterior and its multi-layer paintwork process to the lightweight forged alloy wheels, the duo left no detail unexamined.

Inside the cabin, the focus shifted to luxury and technology. Lei Jun highlighted the use of premium interior materials, designed not just for aesthetics but for durability and comfort. But the real showstopper was the SU7’s 7.1.4-channel audio system—a reference to the number of speakers and subwoofers, promising a concert-hall experience for every journey. For audiophiles and casual listeners alike, this was a clear signal that Xiaomi isn’t just building a car; it’s crafting an immersive environment.

Safety, always a paramount concern in the electric vehicle sector, received special attention. Lei Jun and Zhu Xichan delved into the structural integrity of the SU7, pointing out the use of aerospace-grade aluminum anti-collision beams—a feature more commonly found in high-performance aircraft than consumer automobiles. This choice of material underscores Xiaomi’s commitment to passenger protection, especially in the event of a collision.

But perhaps the most eye-opening segment of the livestream was the battery safety demonstration. In a series of rigorous tests—including high-temperature nail penetration trials—the team showcased the resilience and reliability of the SU7’s power pack. These tests, designed to simulate extreme conditions and potential accident scenarios, are rarely shown to the public, let alone in such granular detail. By doing so, Xiaomi is sending a clear message: transparency and trust are at the core of its automotive ambitions.

The numbers, as always, tell part of the story. Lei Jun revealed that locked orders for the new SU7 have already surpassed 40,000 units—a remarkable achievement for a company making its debut in the fiercely competitive EV market. Even more impressive is the pace of deliveries: since March 23, Xiaomi has delivered more than 7,000 vehicles in just nine days, averaging nearly 800 units per day. This rapid rollout is a testament to the efficiency of Xiaomi’s production lines and the pent-up demand for its first electric car.

The livestream wasn’t just a technical showcase; it was a masterclass in brand building. By inviting an independent safety expert and offering such an in-depth look at the vehicle, Lei Jun positioned Xiaomi as a transparent, trustworthy player in the EV space—one willing to put its technology under the microscope for all to see. This approach is likely to resonate with tech-savvy consumers who value openness and innovation.

Xiaomi’s entry into the automotive sector has been closely watched by industry analysts and competitors alike. With the SU7, the company is not just launching a car; it’s laying the groundwork for a new ecosystem of connected mobility, integrating its strengths in software, hardware, and user experience. The livestream was a clear signal that Xiaomi intends to compete not just on price or features, but on trust, quality, and technological leadership.

As deliveries ramp up and more SU7s hit the roads, all eyes will be on Xiaomi to see if it can maintain this momentum. The early signs are promising, but the true test will come as customers begin to share their real-world experiences. For now, though, Lei Jun’s three-hour teardown has set a new standard for how tech companies can introduce their vehicles—not with smoke and mirrors, but with open doors and open minds.

In an industry where hype often outpaces reality, Xiaomi’s approach is a refreshing departure. By combining technical transparency, rigorous safety demonstrations, and a clear focus on user experience, the company is positioning the SU7 not just as another electric car, but as a benchmark for what’s possible when a tech giant turns its attention to the road.
