小米汽车澎程系列新车在车尾配备后向固态激光雷达，这一配置在同价位车型中较为少见[1]。该雷达测距精度达到2厘米，探测范围覆盖横向140度和纵向105度[1]，能够补齐传统摄像头在低速泊车场景中的感知盲区[1]。激光雷达的选装价格首次下探至9900元[1]。
这一配置反映了智能汽车行业的两大趋势：感知能力竞争从单点性能向全向覆盖转变，以及激光雷达从前向标配向多向多颗配置升级[1]。截至7月31日，澎程系列小订已突破7万台[1]。市场层面，搭载2颗及以上激光雷达的在售车型已超过15款[1]。行业整体而言，2025年国内乘用车激光雷达搭载量预计达324.84万颗，同比增长112%，渗透率突破11%[1]。
Xiaomi's Pengcheng series has equipped its latest model with a rear-facing solid-state lidar sensor, a configuration rarely seen in vehicles at this price point [1]. The lidar on the Pengcheng N90 Max achieves a ranging precision of 2 centimeters and provides coverage across 140 degrees horizontally and 105 degrees vertically [1]. This technology addresses a critical perception gap left by traditional rear cameras during low-speed parking scenarios [1].
The addition of rear-facing lidar reflects a broader industry shift in autonomous vehicle perception capabilities, moving from single-point performance optimization toward comprehensive omnidirectional coverage [1]. The adoption of multi-directional, multi-sensor lidar configurations has accelerated significantly, with over 15 vehicle models currently on sale equipped with two or more lidar units [1]. In the domestic market, lidar sensor installations reached 3.2484 million units in 2025, representing 112% year-over-year growth and a market penetration rate of 11% [1].
Speed Tech, the lidar supplier, has secured partnerships with 36 automakers across 177 vehicle models with over 9 million accumulated unit orders, shipping 719,200 units in the first half of the year [1]. Lidar options have become more accessible, with pricing dropping to 9,900 yuan for the first time [1]. The Pengcheng series has achieved over 70,000 pre-orders as of July 31st [1].
