Get ready to be amazed—Xiaomi’s next-generation SU7 has just shattered records in a jaw-dropping 24-hour endurance test, covering a staggering 4,264 kilometers. But here’s where it gets controversial: Is this the new benchmark for electric vehicles, or just a flashy number that doesn’t translate to real-world performance? Let’s dive in.
Earlier this month, Xiaomi EV opened pre-orders for the revamped SU7, with the official launch set for April. This move comes as the company prepares to challenge the likes of Tesla and other EV giants. The SU7 Max, the star of this endurance test, isn’t just another electric sedan—it’s a powerhouse. Equipped with Xiaomi’s V6s Plus motor, it can hit a mind-boggling 22,000 rpm and reach a top speed of 265 km/h. Built on an 897-volt silicon carbide platform, it houses a 101.7-kWh ternary lithium battery, delivering an impressive 835-kilometer CLTC range per charge. And this is the part most people miss: its peak charging rate of 5.2C allows it to gain up to 670 kilometers of range in just 15 minutes—a game-changer for long-distance travel.
During the test, the SU7 Max maintained speeds of up to 240 km/h for 24 hours straight, including charging time. Xiaomi founder Lei Jun aptly described it as ‘running a marathon at sprint speed.’ This achievement surpasses the previous record of 3,961 kilometers set by Xpeng’s updated P7 model last year. For context, the 2019 Porsche Taycan managed 3,425 kilometers, while the 2024 Mercedes-Benz CLA reached 3,717 kilometers in similar tests. Even the Mercedes-Benz AMG GT XX concept car, which hit 5,479 kilometers in 2025, didn’t face the same mass-production constraints as Xiaomi’s SU7.
But here’s the bold question: Can Xiaomi’s record-breaking performance truly rival Tesla’s dominance in the EV market? The SU7 Max shares its thermal management system with the pricier SU7 Ultra, a feature that could level the playing field. Xiaomi EV, established in 2021, has already made waves with its SU7 sedan, launched in 2024, and the performance-focused SU7 Ultra in 2025. The company also introduced the YU7 SUV in 2025, directly competing with Tesla’s Model Y. With 411,837 vehicles delivered in 2025 and cumulative deliveries reaching 551,308 units, Xiaomi is clearly on the rise.
Looking ahead, Xiaomi EV plans to launch four new models in 2026, including its first extended-range electric vehicle (EREV). The company aims to deliver 550,000 vehicles in 2026, a 34% jump from 2025. But will this be enough to dethrone Tesla? Or is Xiaomi’s focus on record-breaking tests a distraction from real-world usability? Let us know what you think in the comments—is Xiaomi the future of EVs, or just another contender in a crowded market?
