Xiaomi YU7 Features Triple-Redundant Door Handles and Unified Safety Suite Across All Trims; YU7 GT Achieves 663.7 km Real-World Range

Xiaomi Auto has released the results of a real-world range test for its SU7 GT, driving from Shanghai to Qiandao Lake: the total distance covered was 503.7 km, with 23% battery remaining upon arrival. Based on an average energy consumption of 14.9 kWh/100 km, the vehicle could travel approximately another 160 km before the displayed state of charge reaches zero, yielding a total full-charge range of about 663.7 km—achieving a CLTC range compliance rate of 94.1%. The test route included 346.4 km of highway driving (average speed 95 km/h, peak speed 120 km/h) and 157.3 km of lakeside and urban roads (average speed 47 km/h, energy consumption 11.4 kWh/100 km), resulting in an overall average speed of 72 km/h. To balance “1,000 horsepower” performance with long-range capability, the SU7 GT features optimizations across its triple-electric system (battery, motor, and power electronics), thermal management, tires, and low-friction design. The front motor is equipped with an intelligent decoupling mechanism that disengages in Eco mode to reduce drag losses, allowing the vehicle to be driven solely by the rear-mounted Xiaomi Hyper Motor V8s EVO. This motor incorporates a self-developed silicon carbide (SiC) power module, delivering a 5.9% increase in power output, and uses ultra-thin 0.15 mm silicon steel laminations to achieve an efficiency of 98.38%. The thermal management system precisely controls HVAC energy use and is complemented by 21-inch low-drag wheels, long-range tires, and low-drag brake calipers to minimize resistance. All variants of the Xiaomi SU7 share identical safety specifications, with no differences between trim levels. In passive safety, the vehicle features an armored cage-like body structure, with high-strength steel and aluminum accounting for 90.2% of the body-in-white. It includes 2,200 MPa ultra-high-strength steel for integrated roll bars and side-impact beams in all four doors. For active safety, every model comes standard with LiDAR, 4D millimeter-wave radar, and NVIDIA’s Thor chip offering 700 TOPS of computing power, enabling 25 driver-assistance functions—including AEB (Automatic Emergency Braking), AES (Automatic Emergency Steering), MAI (Multi-Angle Intersection Assist), and LCP (Lane Change Protection). In terms of battery safety, all models are equipped with 1,500 MPa scratch-resistant underbody cross members and a bulletproof battery coating. The lithium iron phosphate (LFP) battery pack passed a multi-cell nail penetration test under extreme conditions—simulating equivalent aging after 400,000 km, at high temperature, fully charged, and without liquid cooling—with no thermal runaway, fire, or explosion observed. Additionally, all SU7 models feature triple-redundant door handles with integrated mechanical pull cables and independent backup power for the door locks. Even if both the high-voltage and 12V batteries lose power, the doors can still be unlocked via the central console or manually using the mechanical release.
