Cummins, Isuzu jointly launching medium-duty truck 6.7-liter engine

Cummins and Isuzu s global truck manufacturer headquartered in Japan, are launching a new 6.7-liter engine jointly developed by the two companies, designed for use in Isuzu’s new medium-duty truck lineup. The “Isuzu DB6A” will power on-highway truck applications built for the Japanese market and will be available for the Asia Pacific markets and other global markets later this year. The engine will be assembled at Isuzu’s engine plant in Tochigi Prefecture, Japan. “Today marks an important milestone for both Cummins and Isuzu, as Cummins enters the Japanese on-highway market for the first time in our 105-year history,” said Jennifer Rumsey, Chair and CEO of Cummins. “I’m proud of the strong partnership our two companies have built, and I’m excited to leverage our collective strength and scale to expand our impact and continue meeting the evolving needs of our customers.” Isuzu and Cummins signed the Isuzu Cummins Powertrain Partnership in May 2019 to realize the efficient development of next-generation powertrains. The two companies agreed to collaborate globally in the medium-duty diesel powertrain segment, and the newly developed DB6A is the first engine to be incorporated into the FORWARD medium-duty truck as a result.
