The Chinese language-market Xpeng P5 electrical sedan was once claimed by way of its maker to be the primary automobile on sale with integrated lidar when it was once unveiled in 2021. The P5 makes use of two lidar sensors, one located on both sides of the entrance fascia, for detecting stumbling blocks as a part of its driver-assist tech suite.

Mercedes-Benz and Volvo have invested in Silicon Valley company Luminar, and plan to make use of the corporate’s lidar sensors in long run automobiles. Volvo is integrating lidar sensors into automobile roofs, beginning with the 2024 EX90 electrical SUV, which is because of get started deliveries early subsequent yr. GM has additionally showed lidar will function in its automobiles beginning with the 2024 Cadillac Celestiq, despite the fact that to begin with the lidar might be sourced from provider Cepton.
