Xiaomi SU7 Range and Battery
Xiaomi has pioneered the development of CTB Integrated Battery Technology using innovative Inverted Cell Technology, a versatile elastic interlayer, and a streamlined wiring system. This technology boasts a remarkable battery integration efficiency of 77.8%. This is the highest among CTB batteries globally. It delivers an overall performance improvement of 24.4% and reduces height by 17 mm. With a maximum battery capacity reaching up to 150 kWh and a theoretical CLTC recharge range surpassing 1200 km, Xiaomi’s CTB Integrated Battery Technology sets a new standard in the industry.
Recognizing the importance of safety, this battery has a 14-layer physical protection system – 3 top layers, 3 side layers and 8 bottom layers. With an enhanced heat dissipation system, the battery is capable of resisting temperatures up to 1000°C. To safely control and monitor the entire battery unit, Xiaomi offers a self-developed Battery Management System (BMS) with ASIL-D.

Xiaomi SU7 – E-Motors and Specs
During the conference, Xiaomi presented its independently developed and manufactured E-motors, specifically the HyperEngine V6/V6s, and HyperEngine V8s. These three E-motors utilize innovative technologies, including Bidirectional Full Oil Cooling Technology, S-shaped oil circuit design, and staggered silicon steel laminations design.
The HyperEngine V8s achieves a maximum speed of 27,200 RPM, 425 kW (570 PS) output, and 635 Nm peak torque. This speed is a global record for EVs. To achieve the industry-exceeding standard of 27,200 RPM, the HyperEngine V8s utilizes the industry’s first ultra-high-strength silicon steel plate with a tensile strength of 960 MPa.
In terms of cooling design, the HyperEngine V8s adopts Bidirectional Full Oil Cooling Technology and an S-shaped oil circuit design. For the stator, a dual-cycle oil circuit increases the heat dissipation area by 100%, achieving a cooling effect of up to 20°C. The rotor section utilizes a patented S-shaped oil circuit, increasing the heat dissipation area by 50%, achieving a cooling effect of up to 30°C. Additionally, the stator silicon steel laminations feature a “step-like” staggered design. This further increases the effective heat dissipation area by an additional 7%. The HyperEngine V8s is currently in development and is set to be mass-produced and implemented in Xiaomi EVs in 2025.
Xiaomi’s self-developed HyperEngine V6/V6s E-motors feature an industry-leading rotational speed of 21,000 RPM, surpassing the most powerful mass-produced electric motor globally. The HyperEngine V6 super motor has a maximum power of 299 PS and a maximum torque of 400 Nm. On the other hand, the HyperEngine V6s super motor achieves a maximum power of 374 PS and a maximum torque of 500 Nm.
| E-Motor Specifications | Xiaomi SU7 |
| HyperEngine V8s | 570 PS / 635 Nm |
| HyperEngine V6 | 299 PS / 400 Nm |
| HyperEngine V6s | 374 PS / 500 Nm |
| HyperEngine V8s Max Speed | 27,200 RPM |
| HyperEngine V6 / V6s Max Speed | 21,000 RPM |
| Acceleration (0-100 km/h) | 2.78 seconds |
| Top Speed | 265 km/h |

Interior, Features and Autonomous Driving
The cabin of the Xiaomi SU7 is ultra-modern and tech-heavy. There is a 16.1-inch 3K central console, a 56-inch HUD (Head-Up Display) and a 7.1-inch rotating dashboard with two seat-back extension mounts to connect two tablets. To enable smooth operation across devices and applications, SU7 uses the Snapdragon 8295 in-car chip with AI computing power of up to 30 TOPS. You can connect almost any smart device with the vehicle in a matter of seconds. This enables the Human x Car x Home Smart ecosystem.
To offer insane active safety capabilities, the SU7 comes with two NVIDIA Orin high-performance chips with a total computing power of 508 TOPS, 1 LiDAR, 11 HD Cameras, 3 Millimeter-Wave Radars and 12 Ultrasonic Radars. Xiaomi’s full-stack in-house developed intelligent Autonomous Driving system will take the industry by storm as early as 2024.
