Controversy and Context of the Xiaomi SU7 Ultra’s Power Reduction via an Update
As part of a further technological evolution of electric vehicles, the Chinese brand Xiaomi found itself at the center of a major debate in 2025. The company carried out an over-the-air (OTA) update to one of its most powerful cars, the SU7 Ultra, initially announced with a staggering 1,548 horsepower. This operation resulted in a drastic reduction in power, reduced to 900 horsepower, thus dropping performance by more than 600 horsepower, which did not go unnoticed by buyers. This sudden drop in power is not insignificant, as it represents a reduction of approximately 42% in available driving force, a change that many brand enthusiasts and automotive experts find shocking. Buyers, who had chosen this Ultra version primarily for its ability to go from 0 to 100 km/h in just 1.98 seconds, have seen their expectations dashed. With a price tag approaching €65,000, the disappointment is all the more acute. According to Xiaomi, the stated objective behind this change is « to adapt driving to real-world road conditions » and « ensure user safety. » This reflects a desire to more strictly control the power output to avoid overly aggressive driving behavior. The update also introduced a restriction on Launch Control., with a 60-second waiting time before activation, to prevent the rapid and impulsive starts often observed at red lights.
Such a method opens a serious debate on the practices of manufacturers who increasingly use software updates to modify the real-world performance of their vehicles, without prior customer consultation.
The power of a sports car is no longer solely mechanical but also software-based, which can lead to increased mistrust if these decisions are perceived as arbitrary or an unjustified imposition. 🚗 Xiaomi reduces power by 648 hp via an OTA update;🔥 The impact on performance and customer experience;

Relying on such an update to « tune » power raises important questions on a mechanical, commercial, and emotional level. |
| Technically, a software-based power reduction can serve several purposes. It’s often to prevent premature component wear, reduce energy consumption, or mitigate certain risky situations. However, in this case, this reduction of 648 horsepower is colossal and results in a profound change in the dynamic behavior of a vehicle renowned for its extreme performance, like cars like the Ferrari, Lamborghini, or Bugatti. | From a mechanical perspective, engineers must reprogram the engine management electronics, modify the engine mapping, adjust the cooling system, and, above all, ensure that the car remains reliable and enjoyable to drive despite this considerable loss of power. | From a commercial perspective, the situation is delicate. This type of decision can harm the brand’s image and affect customer confidence. Indeed, those who purchased this model for its extreme power now feel cheated. It’s no longer just a question of pure performance, but also of respecting the commitment between consumers and manufacturers. |

- The Growing Importance of Software Updates in Electric Car Performance Management
- Over the years, electric cars have seen their identity asserted through an unprecedented blend of traditional mechanics and advanced IT management. The case of the Xiaomi SU7 Ultra illustrates a new paradigm: a car’s performance is now largely dependent on software, often modified remotely via OTA updates.
| This process was once reserved for the world of connected objects, but it is now applied to high-end vehicles. This creates new flexibility and allows manufacturers to intervene quickly when necessary, whether for improvements, environmental adaptations, or even safety restrictions. This method has become standard for manufacturers such as Tesla, McLaren, and Alfa Romeo, which regularly offer updates. However, this process also raises concerns regarding transparency, respect for customer rights, and the consistency of the initial offer. Remotely modifying key performance elements without visible consent weakens the relationship between the brand and the buyer. The question now is: how far can software intervention be legitimate without altering the very essence of the vehicle? The Xiaomi case shows that the risk of annoying customers is very real, particularly in the high-power car segment. | Another important issue is the management of warranties and certifications, which can vary depending on the degree of software modification. According to Xiaomi, some buyers have been forced to perform a « qualification lap » to recover 100% of the original power, which further complicates the situation. | 📲 Use of OTA updates to manage the car’s performance; |
