COLUMBUS, Ind. — Cummins, Inc. (NYSE: CMI) and Isuzu Motors Limited announced today another step forward in their partnership, by entering into the Isuzu Cummins Powertrain Partnership agreement.

The agreement formalizes a business structure for the two companies to evaluate and carry out opportunities to jointly develop and bring new diesel and diesel-based powertrains to global markets.

Through this Powertrain Partnership, Isuzu and Cummins share the commitment to leverage both companies’ technical strengths to develop market-leading architectures for customers worldwide.

Cummins and Isuzu committed to forming an alliance board. In particular, they agreed to assign a team of dedicated individuals from each company to continue exploring potential opportunities in product technology development, procurement and manufacturing.
