2 Min Read September 2, 2025
Discover a Deep Dive report on Li Auto L7 Pro’s Horizon Robotics Journey 5 SoC, highlighting advanced ADAS and 128 TOPS AI computing power.
The Li Auto L7 Pro uses the Li AD Pro advanced driver assistance system (ADAS) controller, which is powered by the Horizon Robotics Journey 5 system-on-chip (SoC). The Journey 5 SoC is manufactured using a 7nm process and integrates an automotive-grade CPU, GPU, and AI accelerator, delivering 128 TOPS (trillions of operations per second) of computing power. This controller processes data from the vehicle’s sensors and cameras to enable assisted driving features, including automatic lane change, overtaking, adaptive speed control, and highway ramp navigation. The hardware and system are designed to support these functions efficiently and reliably in the L7 Pro.
The Horizon Robotics Journey 5 (J5) is an automotive-grade system-on-chip (SoC) launched in 2021 for advanced driver assistance systems (ADAS) and autonomous driving applications. The Journey 5 delivers up to 128 TOPS (trillions of operations per second) of AI computing power and supports up to 16 camera inputs via MIPI interfaces, as well as radar and LiDAR sensor integration.
A Deep Dive report is a detailed product disassembly analysis that examines the latest personal electronics and provides unique construction, benchmarking, and cost data in a highly-digestible and graphics-rich format. The products are torn down using proprietary methods developed at TechInsights to provide a disassembly report with a multi-disciplinary "system view."
