Volvo Cars ships the first Rust ECU in production on the SPA2 EV platform: a Cortex‑M4 low‑power ECU fully in Rust including bootloaders, plus a C++ LP agent on the high‑performance computer. Development runs ~3.5 years from zero to production with teams of 6–10, ~130–170k LOC and roughly 18 fault reports total over the project. Tooling includes Tokio, UDS for delivery, custom stacked hardware test rigs (PEEL 2.0), CI-driven fault injection, and production signing.
