General Motors confirmed that the all-new conventional Chevy Class 4/5 commercial truck jointly developed by Chevrolet and Navistar will be powered by a Duramax engine and Allison transmission. Chevrolet made the announcement today at The Work Truck Show 2017, and confirmed the truck is on track to launch in 2018 to join the low-cab Chevy Class 4/5/6 trucks developed with Isuzu already being introduced.
Allison Transmission, based in Indianapolis, is the largest designer, developer, manufacturer and distributor of medium- and heavy-duty fully automatic transmissions, and is a leader in hybrid-propulsion systems. Their designs have been used in a variety of applications, including refuse, construction, fire, distribution, bus, motorhomes, defense and energy.
The first Duramax diesel engines were introduced in Chevrolet and GMC trucks in 2001. Since then, the engines have been continually refined, introducing first-in-class technologies such as aluminum cylinder heads, the quick-start system and the Venturi Jet Drive Oil separator.
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 close to launch.
