Cummins has unveiled its newest product, working with Isuzu to introduce a new 6.7-litre engine, the ‘Isuzu DB6A’.

The engine is specifically designed for Isuzu’s medium-duty truck lineup, and marks a union between the two companies worldwide and in the Japanese market.

While it will start production in Japan, at Isuzu’s engine plant in Tochigi Prefecture, Cummins and Isuzu aim to make the new engine available in the Asia-Pacific market, including Australia, soon.

“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,” Cummins chair and CEO Jennifer Rumsey says.

“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.”

The creation of the new engine marks the next step in Cummins and Isuzu’s working relationship, which was first established as the Isuzu Cummins Powertrain Partnership in May 2019.

In 2022, Isuzu North America then integrated the Cummins B6.7 engine into its FTR and FVR trucks for customers in the United States and Canada.

“We need to invest in both internal combustion engines and electrification to achieve carbon neutrality,” Isuzu Motors chairman and representative director Masanori Katayama says.

“I am convinced that Cummins is the best partner in such a challenging time. Isuzu and Cummins leadership has established strong mutual trust and respect for each other since the first day of our partnership.

“I am confident that our strategic partnership will continue and expand over future generations of respective leadership.”
