Xiaomi lifts the software cap on SU7 Ultra power after owner backlash

Xiaomi has reversed a software update that limited the SU7 Ultra’s full output, restoring the flagship electric sedan’s headline performance after criticism from owners. The rollback removes a dispute that briefly turned one of China’s most aggressively marketed EVs into a test case for how far software controls can reach after delivery.

Xiaomi restores the SU7 Ultra’s full performance output

The company had introduced a restriction that prevented drivers from accessing the SU7 Ultra’s full power in normal use, prompting complaints from buyers who said the change undermined a core selling point of the car. Xiaomi has now backed away from that limit and returned the model to its original performance configuration.

The SU7 Ultra sits at the top of Xiaomi’s EV lineup and was positioned from the start as a high-output halo model. Any post-sale reduction in capability therefore landed harder than a routine software adjustment, because the vehicle’s appeal depends heavily on track-capable acceleration and top-end performance.

Why the rollback matters for software-defined EVs

The episode highlights a growing tension in the electric-vehicle market: automakers increasingly rely on software to manage safety, drivability, and product differentiation, but buyers increasingly expect the hardware they paid for to remain intact. In premium EVs, even temporary changes to power delivery can quickly become a customer-trust issue.

For Xiaomi, the decision to reverse course may help calm owners who viewed the cap as a break from the car’s positioning. It also reinforces a commercial reality that is becoming harder to ignore across the industry: when performance is sold as a feature, it is difficult to take it away without a backlash.

A small change with a larger lesson

The SU7 Ultra’s restored output does not change Xiaomi’s broader EV ambitions, but it does sharpen the scrutiny on how the company manages future over-the-air updates for its vehicles. In a market where software can alter driving feel overnight, the line between product improvement and product dilution is now part of the sales pitch itself.
