Cummins and Komatsu have signed an MOU to *jointly develop hybrid powertrains for heavy mining haul trucks*, with Komatsu’s drive system supplier Wabtec also involved. The effort builds on their long partnership in diesel engines and aims to cut fuel use, lower costs, and speed decarbonization in mining.

Pilot hybrid retrofit kits are set to deploy this year through Cummins’ First Mode unit, with commercial rollout planned well before 2030. Both companies see hybrids as a *first step toward carbon-neutral mining operations by 2050*, while also delivering productivity gains through faster cycle times and double-digit fuel savings.
