General Motors is discontinuing its Chevrolet Silverado MD medium-duty truck lineup. Production will end on September 10, 2026, at the International Motors plant in Springfield, Ohio, where the model has been assembled since 2018.

The Silverado MD was offered in 4500 HD, 5500 HD, and 6500 HD variants, alongside the related International CV. These weren't personal pickups but Class 4–6 work trucks, serving as chassis for tow trucks, vans, specialty vehicles, and municipal equipment.

The reason for the exit is straightforward: the business case didn't add up. According to Transport Topics, GM couldn't justify developing a next-generation model. In 2025, the company sold 8,341 of these trucks, and in the first quarter of 2026, just 1,273 units. In a segment where Ford dominates, that wasn't enough.

The International Motors plant is set to be acquired by Canadian company Roshel, which builds defense, commercial, and armored vehicles. For Roshel, the U.S. site is crucial—it reduces cross-border supply risks and helps secure government contracts. Currently, the plant employs around 1,325 people.

Technically, the Silverado MD was a step up from the regular Silverado HD. Under the hood sat a 6.6-liter turbo-diesel V8 L5D producing 350 hp and 1,017 Nm, paired with a six-speed Allison automatic. The wheelbase ranged from 4,191 to 6,172 mm.

Chevrolet isn't leaving the commercial segment entirely: the low-cab-forward model built by Isuzu will continue for the 2027 model year. But the Silverado MD is being axed without a direct replacement. For GM, this isn't a loud failure—it's a cold calculation: if a work truck can't generate sufficient volume, even the Silverado name can't save it.
