Chevrolet's medium-duty truck will pair a Duramax diesel engine with an Allison transmission and will arrive in 2018, General Motors announced at the Work Truck Show.

Chevrolet and Navistar are jointly developing the Class 4/5 truck for vocational uses such as construction fleets, said John Schwegmen, GM Fleet's U.S. director of commercial product and medium duty.

"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," Schwegman said. "To win customers, we’re marshaling the best diesel and heavy-duty transmission engineers in the world and offering more choices than any other manufacturer."

Chevrolet has been installing Allison transmission in its work trucks since the 1950s. The first Duramax diesel engines were introduced in Chevrolet and GMC trucks in 2001. They use technologies such as aluminum cylinder heads, the quick-start system and the Venturi Jet Drive Oil separator.

Technical specifications for the truck will be released closer to launch.

    Gm already puts a 5.2L I4 diesel in their medium duty cab over trucks. Not sure why they would want to go with the V8 Dmax. Will be harder to work on in that configuration and not offer much more than the 5.2L delivers now. And the Allison is already part of that package.

    Lets forget this diesel stuff epa scr etc asnd go back to simple dependable gasoline powered light trucks. Class 7 33000 down diesel is a joke anyway if those tin horns ever drove 534 Ford IHC 549 orGM478 you would see why
