The two firms said the deal would allow Navistar to strengthen its product line-up and GM to expand its Chevrolet commercial truck portfolio.

"Bringing medium-duty conventional cab trucks back into the portfolio strengthens Chevrolet's commitment to providing commercial customers with more choices and one-stop shopping for a versatile line-up of trucks, vans and crossovers," said Ed Peper, US vice president of GM fleet and commercial sales.

The future products will be jointly developed using Navistar's expertise in rolling chassis configurations and manufacturing capabilities, and GM's commercial components and engines.

The vehicles will be manufactured at Navistar's facility in Springfield, Ohio.

"Our collaboration with GM is another example of our customer-centric, open integration approach—providing our customers with the best technologies available," said Bill Kozek, president, truck and parts, Navistar. "By working with an industry-leading company like GM, we'll be able to enhance our medium-duty product portfolio and leverage our scale and expertise in manufacturing medium-duty trucks."

The firm said that additional product information will be announced later.
