General Motors continues to advance its electrification strategy through the development of scalable Battery Electric Vehicle (BEV) and Battery Electric Truck (BET) platforms. This paper highlights GM’s latest BEV and BET products that leverage shared Drive Unit (DU), Rechargeable Energy Storage System (RESS), and integrated power electronic (IPE) components across multiple vehicle programs. By adopting a modular and commonized propulsion architecture, GM achieves significant benefits in manufacturing efficiency, cost optimization, and product flexibility. The shared DU, RESS, and IPE components are engineered to meet diverse performance requirements while maintaining high standards of energy efficiency, thermal management, and durability. This approach enables rapid deployment of electrified solutions across various segments, from passenger vehicles to full-size trucks, without compromising on capability or customer experience. The paper outlines the technical rationale behind component commonization, including design considerations, validation strategies, and integration challenges. It also discusses the impact of this strategy on development timelines, supply chain resilience, and sustainability goals. Through this shared architecture, GM demonstrates how intelligent component reuse can accelerate innovation, reduce complexity, and support the transition to a zero-emissions future. The findings presented offer valuable insights into the role of scalable propulsion systems in shaping the next generation of electric mobility.
