According to Chinese-language media reports, Xiaomi is poised to unveil its SU7 Extreme variant at a special product launch event scheduled for October 29. Xiaomi’s CEO, Lei Jun, previously announced that their forthcoming electric vehicle will feature the most advanced ceramic brakes ever seen in a high-performance sports car.
Lei Jun, in a recent Weibo post, claimed that the Xiaomi SUV7 Extreme features competition-grade carbon-ceramic brake discs, boasting the largest diameter among high-performance sports car brake discs.
The entrance brake disc measures 430 millimeters in diameter by 40 millimeters thick, while the rear brake disc is slightly smaller at 410 millimeters in diameter by 32 millimeters thick. While the ceramic brakes’ ultimate temperature is reported to surpass 1300°C (2372°F),
These brake systems have primarily been employed in high-performance sports cars and racing vehicles. Ceramic brake components deliver exceptional stopping power thanks to their remarkably lightweight yet incredibly robust design, combined with their impressive high-temperature tolerance.
Carbon-ceramic components can withstand extremely high temperatures of more than 1000°C. Furthermore, these components are immune to thermal degradation regardless of intense overheating, even when subjected to repeated high-intensity braking, a scenario comparable to that experienced on a monitor’s surface.
Compared to traditional forged iron brake discs, they weigh significantly less – a reduction that not only decreases the overall weight of the vehicle but also optimizes handling. The wear and tear on ceramic brake disks is significantly reduced, boasting a lifespan three to five times longer than their metal counterparts, making them an excellent choice for prolonged high-performance applications. Unfortunately, their higher costs are largely attributed to increasing material prices and the complexity of their manufacturing process.
Movies showcasing the devastating consequences of neglected maintenance have highlighted instances where the Xiaomi SU7 suffered catastrophic failure due to brake inefficiencies, culminating in a violent collision with the monitor. This appears to be a crucial consideration in leveraging the capabilities of the previous iteration’s optimization, specifically the Extremely model designed for maximum efficiency.
Estimates indicate costs will start at approximately $1.12 million, with Goldman Sachs projecting 4,000 units of gross sales by 2025.
The Xiaomi SU7 Extremely is expected to be street-licensed, unlike the prototype model. Despite initial reports suggesting significant changes, the powertrain appears to remain unchanged, comprising three high-performance motors from Xiaomi: two V8 units and one V6 unit. The collective motors form a three-motor four-wheel-drive system, boasting a total energy output of up to 1,138 kW (1,548 PS).
This exceptional vehicle boasts a remarkable 0-100 km/h acceleration time of just 1.97 seconds, accompanied by a top speed exceeding 350 km/h.
The Xiaomi Su7 Extreme boasts an impressive 150kWh battery pack, which leverages the advanced Qilin 2.0 technology from industry leader CATL. Xiaomi leverages a innovative CTB (cell-to-body) design, seamlessly integrating the battery into the vehicle’s structure, which enhances overall rigidity while minimizing weight. The generator’s maximum output is approximately 1,330 kilowatts. The innovative dual-surface cooking system boosts cooling efficiency by an impressive 60%, empowering high-speed driving capabilities.
