Gasgoo Munich- SiEngine unveiled its "Longying II" on April 27 — a 5nm, automotive-grade chip designed to fuse cockpit and driving functions. Unveiled at the 2026 Beijing International Auto Show, the company plans to begin adaptation in the first quarter of 2027.Image Source: SiEngineSiEngine has been advancing integrated cockpit, driving, and parking technologies since its first-generation "Longying-1" cockpit SoC. The new "Longying II" advances this integration, combining AI, smart cockpits, and intelligent driving into a single package.Designed specifically for AI-driven cockpit and driving scenarios, the "Longying II" features 200 TOPS of AI computing power and native support for multimodal large language models (LLMs) with over 7 billion parameters. It features active intent perception capabilities, a multi-core CPU delivering 360 KDMIPS, and a GPU reaching 2,800 GFLOPS. With bandwidth peaking at 518 GB/s and support for LPDDR6/5X/5, the chip eliminates data bottlenecks in multi-screen interactions and AI computing."The 'Longying II' covers the full spectrum of AI cockpit and cockpit-driving fusion scenarios," said Wang Kai, founder and CEO of SiEngine. Its flexible architecture is designed to adapt to the evolution of automakers' central computing platforms — from entry-level to flagship models.On the safety front, the chip employs hardware-level physical isolation. It integrates a dedicated vehicle control processing unit and a safety island, supporting the CAN-FD bus. By using hardware partitioning and an independent redundancy architecture, it achieves physical separation between cockpit and driving functions. According to reports, even if the cockpit system is under heavy load or rebooting, intelligent driving and vehicle control operations remain stable.
