Xiaomi’s Updated SU7 Launches With 897V Charging Tech and Up to 902 km of Range

Xiaomi has pushed its SU7 electric sedan into a more mature phase, rolling out a refreshed version in China that leans harder on charging speed, efficiency and hardware upgrades rather than a wholesale redesign. The new car brings a revised powertrain lineup, a higher-voltage electrical architecture on the top trim and a set of safety changes that make the sedan feel less like a fast-starting tech product and more like a serious premium EV contender.

Xiaomi sharpens the SU7’s hardware

The biggest change is under the skin. Xiaomi says the updated SU7 uses a V6s Plus motor across the range, with the Standard version rated at 320 horsepower and the Max at 690 horsepower. The Standard and Pro trims run on a 752V architecture, while the Max steps up to 897V, a setup designed to improve charging performance and overall electrical efficiency.

Range figures are equally central to the refresh. Xiaomi quotes 720 kilometers of CLTC range for the Standard model and 902 kilometers for the Pro, placing the car firmly in the long-legged end of the Chinese EV sedan market. Those numbers are measured on China’s CLTC cycle, which tends to be more generous than the EPA testing used in the United States.

Safety and chassis updates move up the priority list

Xiaomi has also expanded the SU7’s safety equipment. The company says all versions now come with a 2,200MPa embedded steel roll cage, side-impact beams in all four doors and a nine-airbag setup that adds rear side airbags. The body structure also gets a 1,500MPa protective beam and a tougher coating on the chassis-related surfaces.

The updated sedan also addresses one of the more practical criticisms that can follow a feature-heavy EV launch: door usability. Xiaomi says the new handles now have triple redundancy and can still be opened mechanically from inside or outside the car, giving the design a more conventional backup path if electronics ever fail.

Why the refreshed SU7 matters for buyers

For shoppers in China, the update signals that Xiaomi is trying to keep the SU7 competitive against well-established electric sedans without relying only on brand heat. The higher-voltage hardware should be especially relevant for drivers who want shorter charging stops, while the expanded range and added safety equipment help the car read as a more complete product for daily use, long-distance travel and premium-family duty.

The refreshed SU7 also shows how quickly Xiaomi is iterating in automotive. After arriving as a newcomer, the company is now refining its sedan around the exact details that matter to EV buyers: charging speed, real-world usability, range confidence and performance that still looks headline-worthy on paper. For a first-generation nameplate, that is a meaningful step.
