Chevrolet will debut the next-generation Silverado HD next year as a 2020 model. It will be the third new truck in the Silverado lineup in just 18 months, joining the 2019 Silverado 1500 and the 2019 Silverado 4500/5500/6500HD.

“Chevrolet already fuels the most successful truck manufacturer in the industry,” said Alan Batey, global head of Chevrolet. “With a completely new, expanded range of Silverado models on the horizon, we expect to see even more truck buyers in Chevrolet showrooms.”

The next-generation Silverado HD will be designed for the specific priorities and needs of heavy-duty truck customers, according to Chevrolet. On-road testing of the new Silverado HD prototypes will begin in the near future to reach the company’s increased durability and validation standards, and the truck will have bolder, larger proportions.

More product information will be provided next year, with the first production models scheduled to roll off the assembly lines in Flint, Michigan in the third quarter of next year.

The 2019 Silverado 1500 was introduced in January. It weighs less than the outgoing model-up to 450 pounds less for crew cab V-8 models. The new Silverado 1500 also offers a range of trims and engine and transmission combinations.

The 2019 Silverado 4500HD, 5500HD, and 6500HD chassis-cab models were introduced in March and are scheduled to go on sale later this year. According to Chevrolet, these Silverado medium-duty trucks are designed specifically for commercial customers, with an emphasis on being easy to drive, easy to upfit and easy to service.
