The Controversy Surrounding the Xiaomi Su7 Ultra’s Brakes
The Xiaomi Su7 Ultra has garnered significant attention in the automotive world, especially as one of the latest entries from the renowned Chinese tech giant. However, as features unfold, the conversation has turned to concerns regarding its braking system. While many appreciate its performance , the reality behind its brake specifications raises eyebrows, leading some to question whether the vehicle’s design leans more towards aesthetics than functionality.
Shocking Discoveries: The Size of Brake Pads
Insider investigations reveal that the brake pads utilized in the Xiaomi Su7 Ultra are significantly smaller than one might expect for a vehicle boasting nearly 700 horsepower . The disassembly of the brake system unveiled that the brake pads are only marginally larger than those of a Seat Ateca , raising questions about their capability to handle such power and weight.
The overwhelming size of the brake housing does not equate to the actual efficiency or power of the brakes. This realization has left many enthusiasts wondering if the design is merely for show , as experts from Motorpasion emphasize, “There is more decorative clamp than real braking power.”
Overheating: A Major Concern
Instances of overheating have surfaced involving test drives of the Xiaomi Su7 Max, which uses a similarly designed braking system. During a circuit test, driver Tang Zhu Liao Che found himself short on brake performance, leading to a harrowing encounter with barriers due to brake failure caused by excessive heat.
Another alarming event was reported at the Tianjin V1 circuit where the brake pads reached temperatures exceeding 600 degrees , resulting in complete brake failure and even igniting a fire. Such incidents shine a light on the serious safety risks associated with inadequate brake sizing for a high-performance vehicle.
Size vs. Performance: A Critical Shortcoming
The feedback from early users leads many to question: can these brakes truly maintain integrity under extreme conditions? Critics argue that the brakes are insufficient for a vehicle weighing over 2 tons and designed for high-speed circuit-style driving.
Xiaomi’s promotion of the Su7 Ultra as a premier track-ready vehicle further compounds these concerns. While it is equipped with Brembo brakes , the size of those breaks appears to contradict the marketing narrative. A smaller disc size inherently raises the likelihood of overheating, which can severely compromise braking performance during rigorous use.
Style Over Substance: A Pattern?
This is not the first time Xiaomi has mixed form with function poorly. Earlier, it surfaced that the cosmetic modifications, including a sporty hood that touted aerodynamic benefits , had no practical effect on vehicle performance. Buyers expressed frustrations concerning deceptive advertising, pushing the company to withdraw these features from future orders.
Xiaomi’s Defensiveness Amid Criticism
<pFollowing incidents involving the braking system, Xiaomi’s official stance argued that the overheating issues stemmed from operational lapses—specifically, not conducting a proper warm-up before intense driving sessions. Their response framed the brake failures as preventable through correct practices.
Nonetheless, concerns surrounding the overall brake performance remain legitimate. It becomes particularly disheartening when comparisons are made with other high-performance electric vehicles. For instance, a Tesla Model S, with considerably less horsepower, boasts larger brake discs—around 355 mm , while the Porsche Taycan GTS presents even more substantial braking components at 390 mm in diameter.
As the electric vehicle market grows increasingly competitive, organizations like Xiaomi will need to prioritize real performance over flashy designs if they hope to compete successfully against established brands known for their engineering excellence.
No one doubts the effectiveness of the Xiaomi Su7 Ultra. But more and more details that make us ask ourselves if the most special sportsman of the Chinese firm dresses with too much paraphernalia. The last thing we know Apuna to it, with disc brakes that, in reality, hide a minimum size pills.
This article provides an in-depth analysis of the Xiaomi Su7 Ultra’s braking system, focusing on its design, performance concerns, and the implications for the company moving forward.
