Dana TM4 is a leading Canadian electric vehicle (EV) engine manufacturing company and a global powerhouse in the design and production of electric motors, generators, inverters, and control systems. Born from a joint venture between Dana Incorporated and Hydro-Québec, Dana TM4 has over 30 years of innovation stemming from Hydro-Québec’s research center, evolving into a pivotal player in electrification technology across automotive, commercial, off-highway, marine, rail, motorsports, and recreational vehicle markets.
Company Origins and Evolution
Originally established as TM4 Inc. in 1998, the company began as a research arm focused on commercialising electric power-train technologies developed by Hydro-Québec. In 2018, a strategic alliance with Dana Incorporated led to its re-branding as Dana TM4, joining Dana’s global footprint and manufacturing prowess with TM4’s advanced electric power-train expertise. This collaboration propelled Dana TM4 into a global player with facilities in Canada, the U.S., Italy, China, Sweden, and India, enabling high-volume manufacturing matched with continuous technology development.
