In March 2017, Chevrolet announced plans to introduce a “flagship, medium duty truck”. In the announcement, Chevy confirmed that the upcoming Medium Duty truck will:
- Utilize a Duramax turbo-diesel engine
- Utilize an Allison transmission
- Launch in calendar year 2018
- Be co-developed with Navistar, which operates the International Trucks brand
- Not be related to the Chevrolet Low Cab Forward medium duty trucks sourced from Isuzu
At the time, no name was assigned for the vehicle.
The announcement also confirmed that GM would supply commercial components and engines while Navistar would provide its “expertise in rolling chassis configurations and manufacturing capabilities”. Based on the statement, it would appear that the upcoming Chevrolet Medium Duty truck will use a GM-sourced powertrain and other components, while Navistar will be responsible for developing other parts of the vehicle as well as manufacturing it.
In September 2017, Chevrolet announced more information about the Medium Duty truck, including that the vehicle will:
- Actually consist of two vehicles
- Slot in the Class 4 and Class 5 medium duty segments and be called Silverado 4500 and Silverado 5500
- Be “powerful, highly maneuverable, and among the easiest trucks on the market to upfit with specialized bodies, such as dump bodies, rollbacks, freight boxes and more”
- Be available in Regular Cab and Crew Cab models with 4×2 and 4×4 capability
- Be available in a wide range of GVWRs and wheelbases
- Offer optional OnStar with 4G LTE connectivity that is being embraced by fleet management companies to help improve safety and productivity thanks to tools like OnStar Commercial Link
Chevrolet also announced that all Silverado 4500 and 5500 models will be powered by a Duramax diesel engine and Allison transmission and that the trucks will “stand out because we’ve designed the trucks around how customers work.”
We expect that the Duramax engine that will be used in the future Chevrolet Silverado Medium Duty Trucks will be none other than GM’s new 6.6L Duramax Turbo-Diesel L5P engine. In the 2017 Chevrolet Silverado HD, it makes 445 horsepower and 910 pound-feet of torque.
General Motors has confirmed that its new Conventional Medium Duty Trucks for the Chevrolet brand, with the vehicles being branded Silverado 4500 and Silverado 5500.
It is currently unknown whether GM’s GMC brand will get a variant of the Conventional Medium Duty Truck.
Chevrolet has confirmed that its upcoming Medium Duty Trucks will be branded as Silverado 4500 and Silverado 5500.
If a GMC variant comes to market, it could be branded as:
- GMC Topkick
- GMC HD 5500/6500
- GMC Sierra 5500/6500
- GMC Sierra HD 5500/6500
Introduction Date & Model Year
GM confirmed that the upcoming Chevrolet Medium Duty conventional truck will “launch in 2018”. As such, the vehicles will likely be designated model year 2019.
The Chevrolet Medium Duty truck will be offered as a conventional truck with an engine/hood-forward design and be available in Regular Cab and Crew Cab configurations in various wheelbases and GVWRs.
We expect the future General Motors Medium Duty conventional truck to have a starting price in the $60,000 range for the work truck configuration and reach as much as $130,000 for the range-topping model.
Given that GM is co-developing its next Medium Duty truck with Navistar, we expect that Navistar will also sell a version of the truck. The final variant for Navistar could become the next-generation International Trucks DuraStar.
The future GM Medium Duty truck will likely be manufactured by Navistar in the United States of America. One of the more likely facilities to make the truck is Navistar’s Garland, Texas factory.
Conventional Medium Duty trucks serve as platforms for a wide variety of commercial applications, such as traditional pickup trucks, emergency services, towing, dump truck, flatbed truck and cargo box truck. Some medium duty trucks are commonly used as a platform for both school buses and commercial buses.
