UK-based arms, security and aerospace multinational BAE Systems will supply as many as 541 Gen3 electric power and propulsion systems for Toronto Transit Commission’s (TTC’s) new fleet. 

The Gen3 system includes an electric motor and power electronics, and uses materials like silicon carbide to increase power density and electrical efficiency. It features a compact design with fewer components and connections and reduced weight compared to the previous version. Its modular architecture, employing the same core technology used for hybrid buses, is intended to ease the transition to all-electric operation.

An updated version of the company’s proprietary Intuitive Diagnostic Software (IDS), already used by TTC in its hybrid fleet, will provide power management system diagnostics and troubleshooting capabilities for all Gen3 system components.
