Duramax engine and Allison transmission will power Chevrolet’s all new medium duty commercial truck.

GM has announced that Chevrolet’s all-new Class 4/5 commercial truck will be powered by a Duramax engine and Allison transmission. The announcement was made at The Work Truck Show 2017, and GM confirmed the truck is on track to launch in 2018.

“Our new Chevrolet medium-duty will be the flagship of our truck portfolio for fleet and commercial customers, and we believe the strength of Duramax/Allison powertrain combination will be able to tackle various jobs—from general contracting to urban delivery to bucket loaders and wreckers,” said John Schwegman, U.S. Director of Commercial Product and Medium Duty for GM Fleet. “To win customers, we’re marshalling the best diesel and heavy-duty transmission engineers in the world and offering more choices than any other manufacturer.”

Technical specifications for Chevrolet’s new medium-duty truck, along with pricing, will be released closer to launch.
