Get ready to be amazed: Xiaomi’s next-generation SU7 electric sedan has just shattered records in a jaw-dropping 24-hour endurance test, covering an astonishing 4,264 kilometers. But here’s where it gets controversial—is this the new benchmark for mass-produced EVs, or just a flashy PR stunt? Let’s dive in.
Xiaomi EV, the electric vehicle arm of the tech giant Xiaomi (HKG: 1810, OTCMKTS: XIACY), recently unveiled the results of its grueling endurance test for the updated SU7 model. This isn’t just a small win—it’s a game-changer. The SU7 Max variant blew past the previous record of 3,961 kilometers set by Xpeng’s P7 model last year. And this is the part most people miss: Xiaomi’s achievement wasn’t just about distance; it was about pushing the limits of what a mass-produced EV can do.
During the test, the SU7 Max hit speeds of up to 240 km/h and operated continuously for 24 hours, including charging time. Xiaomi founder Lei Jun aptly described it on Weibo as ‘running a marathon at sprint speed.’ But what makes this feat even more impressive is the technology under the hood. The SU7 Max is powered by Xiaomi’s V6s Plus motor, capable of 22,000 rpm and a top speed of 265 km/h. It’s built on an 897-volt silicon carbide high-voltage platform and packs a 101.7-kWh ternary lithium battery. With a peak charging rate of 5.2C, it delivers an 835-kilometer CLTC range per charge—numbers that are hard to ignore.
But here’s the controversial part: While Xiaomi’s SU7 Max has set a new record, some critics argue that such extreme tests don’t reflect real-world driving conditions. Is this just a marketing gimmick, or a genuine leap forward in EV technology? We’ll let you decide.
To put Xiaomi’s achievement in perspective, let’s compare it to other vehicles. In similar tests, the 2019 Porsche Taycan managed 3,425 kilometers, and the 2024 Mercedes-Benz CLA reached 3,717 kilometers. Even the Mercedes-Benz AMG GT XX concept car, which completed 5,479 kilometers in 2025, is a different category altogether—a concept car, not a mass-produced vehicle. So, Xiaomi’s SU7 Max isn’t just competing; it’s leading the pack.
Xiaomi EV has been on a roll since its establishment in 2021. The company launched its first model, the SU7 electric sedan, in March 2024, positioning it as a direct competitor to Tesla’s Model 3. The SU7 Ultra, a performance-enhanced version, followed in February 2025, and the YU7 SUV, aimed at rivaling Tesla’s Model Y, debuted in June 2025. With pre-orders for the facelifted SU7 opening earlier this month and an official launch scheduled for April, Xiaomi is clearly doubling down on its EV ambitions.
In 2025, Xiaomi EV delivered 411,837 vehicles, bringing its total deliveries to 551,308 units. The SU7 alone accounted for 258,164 units, while the YU7 delivered 153,673 units. Looking ahead, Xiaomi plans to launch four new models in 2026 and enter the extended-range electric vehicle (EREV) segment for the first time. With a target of 550,000 vehicle deliveries in 2026—a 34% jump from 2025—Xiaomi is clearly aiming for the top.
But here’s the question we can’t stop thinking about: Can Xiaomi sustain this momentum, or will it face challenges in an increasingly crowded EV market? And more importantly, does this record-breaking endurance test signal a new era for electric vehicles, or is it just a fleeting moment of glory?
