Detroit automaker General Motors Co. today announced that Chevrolet’s all-new Class 4/5 commercial truck will be powered by a Duramax engine and Allison transmission, a combination that has already powered nearly two million trucks. Chevrolet made the announcement at the 2017 World Truck Show and confirmed the truck is on track to launch in 2018, following a joint development by Chevrolet and Navistar.

“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,” says 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.”

The first Duramax diesel engines were introduced in Chevrolet and GMC trucks in 2001, and they have accumulated more than 100 billion miles of real-world experience since. The engines have been continually refined, introducing first-in-class technologies such as the aluminum cylinder heads, quick-start system, and the Venturi Jet Drive Oil separator.

Indiana-based Allison Transmission is a designer, developer, manufacturer, and distributor of medium and heavy-duty fully automatic transmissions and hybrid-propulsion systems. Their designs have been used in several industries, including: refuse, construction, fire, distribution, bus, motorhomes, defense, and energy. The company has been working with Chevrolet since the 1950s.

Technical specifications for Chevrolet’s new medium-duty truck, including cab and frame dimensions, horsepower and torque, GAWR, GVWR, payload and other ratings, will be released closer to the launch.
