Xiaomi's SU7 Ultra Software Update Resulted in a 650-HP Reduction | Carscoops

      Xiaomi has reversed its decision regarding a software update that limited the 1,548 hp SU7 Ultra to just 888 hp.

      Previously, owners needed to complete a qualifying time on a racetrack to access the EV’s full performance capabilities.

      Additionally, Xiaomi has eliminated the 60-second waiting period for the launch control to activate on this competitor to the Taycan.

      Have you ever upgraded your phone or computer to the latest operating system only to regret it immediately, wishing you could revert to the previous version? This situation has become familiar to owners of the Xiaomi SU7 Ultra, who found that an update cost them nearly 650 hp.

      The Ultra stands as the flagship model in Xiaomi’s highly successful SU7 series, competing with the Porsche Taycan Turbo GT at a fraction of the price, and has outperformed the German vehicle at various racetracks, thanks to its impressive 1,526 hp (1,548 PS / 1,138 kW) triple-motor drivetrain.

      However, owners were infuriated to discover that version 1.7.0 of the software limited power to approximately 888 hp (900 PS / 662 kW) unless they could demonstrate their capability for the full potential. To unlock the true power, drivers were required to achieve a qualifying lap time on an approved Xiaomi racetrack, with their time recorded and verified by the SU7’s onboard qualifying mode assessment feature, as reported by Car News China.

      Additionally, the update imposed an excruciating 60-second wait for the launch control to activate, thereby eliminating the option for spontaneous races from a standstill despite the Ultra's impressive potential of 1.89 seconds from 0 to 62 mph (96 km/h).

      Xiaomi stated that the restrictions in the 1.7.0 update were implemented with safety in mind, suggesting that such maximum performance was intended solely for track use and for drivers capable of handling that level of power. While some owners recognized the intention, many took to online platforms to express their frustration, stating that they had purchased EVs with significantly less performance than advertised.

      In response to the backlash, Xiaomi has backtracked, removing the performance restrictions and vowing to provide clearer communication regarding future software updates.

      A company representative stated, “We appreciate the passionate feedback from our community and will ensure better transparency moving forward,” according to Car News China.

      Do you believe Xiaomi was justified in requiring drivers to validate their skills before granting them full access to the SU7’s power?
