When Xiaomi launched the SU7 in 2024, it entered a market already full of competent Chinese electric sedans and immediately stood out: sharp styling, strong smart home integration, a big frunk, and performance that embarrassed cars costing twice the price. Two years later the competition has caught up, and Xiaomi has responded with a meaningful update rather than a cosmetic refresh. The 2026 SU7 moves from a 400V to an 800V-class electrical architecture, boosting max charging voltage to 752V on standard and Pro trims and up to 900V on the Max. Long-range CLTC range climbs by more than 70 km over the outgoing car. Four-piston brake calipers, borrowed from the SU7 Ultra, arrive across the range. And the platform now offers dual-chamber air suspension and continuous damping control on higher trims, giving drivers genuine ride flexibility rather than a fixed compromise between comfort and handling.
The 800V upgrade is the headline spec change and it matters more than the range number. The previous SU7 used a 400V system, which is the same architecture as most EVs on sale today including the standard Model 3. Moving to 800V class means faster charging not just in peak kilowatts but in how long the peak can be sustained. The 2026 SU7 on Max trim can charge from 10 to 80 percent in roughly 12 minutes under ideal conditions. The Hyundai Ioniq 6 and Porsche Taycan, both 800V platforms, have been cited as benchmarks for fast DC charging in the EV press, and Xiaomi is now in that tier at a price point that undercuts both significantly in markets where it is sold. China has banned electrically-actuated pop-out door handles from 2027, and Xiaomi's response on the 2026 SU7 is three redundant opening mechanisms: a normal pull, a mechanical backup lever on the exterior, and a clearly marked red lever inside. It is an unusual amount of engineering attention to a door handle, but the underlying problem is real: a locked-shut door on a crashed EV is a serious safety issue.
The interior sees updated seats, laminated glass for cabin noise reduction, an 80W wireless charging pad, and a revised centre console with metal accents in place of physical buttons. Top trims get a carbon fibre and Alcantara steering wheel and an upgraded audio system. The rear is unchanged in the ways that matter: headroom is tight for tall passengers, knees sit high in the sedan body, and it is best suited to two adults or smaller passengers. The frunk is now electrically actuated. The rear gains dual independently dimmable sunroofs rather than a single panoramic pane, and Xiaomi has added a small refrigerator. On the road, the reviewer describes it as lighter and more nimble than the XPENG P7, which they had previously rated as one of the strongest EV driving experiences available. A direct comparison video between the two is forthcoming from the same channel.
Bottom line: The 2026 SU7 fixes the one thing that held the original back in a head-to-head with premium European competition: charging speed. The 800V architecture puts it on the same platform as the Taycan and the Ioniq 6. If Xiaomi ever brings this car to European or North American markets, those brands will feel the pricing pressure directly. For buyers in China, this is almost certainly the best all-round EV sedan available at this price. The only real question is whether you want the base SU7 or the Ultra, and the base version's 0-100 km/h time makes that a much harder call than it was two years ago.
