US-based electric vehicle (EV) manufacturer Proterra is set to revolutionize the heavy-duty EV market with a major upgrade to its Onyx battery platform. Starting in 2027, the company will offer a US-made cell option for its Onyx platform, marking a significant shift towards domestic production and reduced reliance on international suppliers. This move is expected to enhance the platform's efficiency, reliability, and overall performance, making it an attractive option for fleets and operators seeking to transition to electric vehicles. As the demand for heavy-duty EVs continues to grow, Proterra's decision to offer a US-made cell option is poised to play a crucial role in shaping the future of the industry.
