Imagine an electric vehicle that has traveled an incredible 165,000 miles in just over a year and a half, revealing some surprising insights about battery performance and overall durability. This remarkable journey belongs to a Xiaomi SU7 owner in China who has pushed this electric sedan far beyond typical usage levels, averaging a staggering 373 miles daily—more than the average taxi driver.
Recently, a video shared on Bilibili by Jackson’s Sunset Drive showcased this extraordinary vehicle journey. Owned by Mr. Feng, the Aqua Blue SU7 Pro has managed to cover a distance equivalent to 6.63 times the Earth's circumference in just 476 days, which is roughly the distance between Los Angeles and San Francisco!
Battery Performance After Extensive Use
One of the most striking aspects of this high-mileage case is the health of the car's battery, as assessed by an official Xiaomi service center. Despite the demanding use, the 94.3 kWh lithium iron phosphate battery from CATL has impressively maintained 94.5% of its original capacity. For comparison, Tesla’s Model 3 Long Range comes with an eight-year warranty covering 120,000 miles, guaranteeing a minimum battery health of 70% after that period.
Minimal Maintenance Needs
What’s even more remarkable is that Mr. Feng has never had to replace the brake pads, thanks to the vehicle's efficient regenerative braking system. Additionally, the coolant remains uncontaminated, demonstrating the vehicle's reliability under strenuous conditions. The Pro variant of the SU7 is equipped with a rear-mounted motor that delivers 295 horsepower and 400 Nm of torque, while the battery allows for an impressive range of approximately 830 kilometers (516 miles) under the Chinese light-duty test cycle (CLTC).
Cost Savings Through Electric Driving
Calculating the energy consumption, Mr. Feng’s Xiaomi has utilized nearly 47,800 kWh of electricity over this time frame, which equates to around 506 complete charge cycles for the battery. He estimates that choosing this electric sedan instead of a traditional combustion engine vehicle has saved him over ¥100,000 (approximately $14,400) in fuel costs throughout his extensive travels. This is particularly significant given that the starting price for a Xiaomi SU7 Pro in China is around ¥245,900 ($35,400).
The compelling details of this ownership experience have captured considerable attention, even prompting Xiaomi CEO Lei Jun to share the video. Mr. Feng has ambitious plans to reach 600,000 kilometers (372,823 miles) within three years.
As the Xiaomi SU7 continues to gain popularity, it has recently surpassed the Tesla Model 3 in sales within China, delivering 258,164 units in 2025 alone. The company is also preparing to release an updated version of the sedan in April 2026, which promises enhanced advanced driver-assistance systems (ADAS), standard LiDAR technology, and an extended driving range of up to 560 miles (902 kilometers) in the CLTC cycle.
This case raises important questions about the future of electric vehicles and their potential longevity and cost-effectiveness. Could the Xiaomi SU7 be paving the way for more reliable EVs?
