What Dana TM4 does

Dana TM4 Inc. is a Canadian-incorporated, wholly-owned subsidiary of Dana Incorporated (NYSE: DAN) that designs, manufactures, and supplies electric and hybrid propulsion systems for vehicle and machinery OEMs. The product portfolio includes high-voltage and low-voltage electric motors (permanent magnet synchronous, switched reluctance, induction, and interior permanent magnet types), traction and auxiliary inverters spanning 24V to 900V, and integrated motor-inverter systems under the TM4 MOTIVE and TM4 SUMO (LD, MD, HD, HP) product families. The technology foundation rests on 75+ registered patents developed over 30+ years of R&D, including patented DBC MOSFET multilayer power modules for low-voltage inverters, ASIL D functional safety certification, and proprietary simulation tools used to harmonize powertrain components. The SUMO direct-drive architecture interfaces directly with standard axles, differentials, and gearboxes without requiring an additional gearbox, simplifying OEM integration with Dana e-Axles and gearboxes.

The company operates exclusively through B2B OEM channels with quote-based pricing tailored to customer specifications and volumes. Sales and application engineering teams collaborate with OEMs from concept through production, embedding powertrain components into platforms across light vehicles, commercial vehicles (Class 4–8 trucks and buses), material handling, construction vehicles, mining vehicles, and specialty electric applications (motorcycles, golf cars, 3-wheelers). Manufacturing is distributed across six countries — Canada (Boucherville HQ), United States, Italy (Arzignano), India (Pune), China (Shanghai and Weifang), and Sweden (Åmål) — with end-of-line functional and performance testing on each line.

Dana TM4's structure traces through the 2018 Dana Incorporated majority acquisition of TM4 Inc. from Hydro-Québec for CA$165M (~$US127M), followed by integration of SME Group (Italy, 2019), Ashwoods Electric Motors (2019), full ownership of Dana Electric Motor Co. Ltd (formerly Prestolite E-Propulsion Systems, 2012 JV with 2019 consolidation), Schwarzmüller Inverter (2016), Pi Innovo (2021), and Nordresa (2019). The 2026 acquisition of remaining Hydro-Québec shares made Dana TM4 a wholly-owned subsidiary. Named OEM customers include Hyliko (hydrogen trucks), Chinese bus manufacturers (10,000+ SUMO systems milestone), TEMSA Global (commercial vehicles), Zero Motorcycle (high-performance electric motorcycles), and major golf car manufacturers.
