How LiDAR works on the SU7

All 2026 SU7 trims now ship with a roof-mounted LiDAR module, paired with 4D millimetre-wave radar and 700 TOPS of compute.

Xiaomi's decision to make LiDAR standard across all 2026 SU7 trims — including the entry Standard model — is unusual in the price segment. Most competitors at the ~¥230,000 (~$33,000) starting price still rely on vision-only or radar-only systems. This page covers what's actually on the car, how it integrates with the broader sensor suite, and where it helps in real driving.

Hardware breakdown

LiDAR Vendor	Hesai (publicly reported supplier; subject to change as Xiaomi diversifies)
Channels / Resolution	Long-range solid-state LiDAR with hybrid scanning; effective angular resolution sufficient for 200+ m object detection.
Effective Range	~200 m for vehicle-class targets in clear conditions; ~120 m for pedestrians.
Field of View	Wide horizontal sweep oriented forward; covers oncoming and adjacent lanes at highway speeds.
Placement	Roof-front, integrated into the windshield header housing — visible as a slim raised module on all trims.
Compute	Unified 700 TOPS platform shared by camera, radar, and LiDAR fusion.
Sensor Fusion	LiDAR + 4D mmWave radar + multi-camera + ultrasonic; all running on one compute domain to reduce latency between modalities.

Real-world value

Where LiDAR actually helps

Highway cut-ins

LiDAR provides instant 3D distance to vehicles entering your lane at highway speed — critical when sun glare or rain confuses cameras.

Pedestrians at night

Standard cameras struggle in low-light scenes. LiDAR detects pedestrian silhouettes regardless of illumination, dramatically improving emergency-braking confidence.

Stationary obstacles on highways

Vision-only systems have historically had blind spots for stopped trucks or debris. LiDAR's distance measurement is independent of motion.

Construction zones

Cones, barriers, and lane closures — many of which are not in HD-map data — are detected as discrete 3D objects rather than guessed from 2D images.

Bottom line

Standard LiDAR on a ~$33,000 sedan is a meaningful spec sheet win for Xiaomi. The hardware is genuinely useful in edge cases that frustrate vision-only systems, especially on Chinese expressways with frequent construction. Whether the software stack matches Tesla's mature FSD remains to be seen — hardware is necessary but not sufficient.
