As Chevrolet continues to make over its full-sized pickup truck line, it has unveiled its next-generation Silverado HD, a heavy-duty truck often referred to as a 2500 or ¾-ton.

Where previous light- and heavy-duty Silverados looked similar, the 2019 Silverado and the upcoming 2020 Silverado HD are more visually distinguished from one another.

For instance, the massive grille has a horizontal bar bearing the brand's name—a trend seen with rival full-sized trucks. There's no Chevrolet bowtie logo, at least on the off-road-focused Z71 version.


“We know the needs and priorities of heavy-duty customers are different than those of either light-duty or medium-duty customers,” said Jaclyn McQuaid, chief engineer for the Silverado HD, in a statement. “As such, we built a heavy-duty truck tailor-made for them that has more differentiation than ever before from light-duty models.”

The Silverado HD exterior shares only its roof with the light-duty Silverado. All other visible elements are unique to the work-focused HD truck. Chevrolet says the interior has an additional 3 inches of legroom for second-row passengers in crew-cab models.

The 2020 Silverado HD is quite a bit bigger than the 2019 model, riding on a 5.2-inch longer wheelbase, measuring an extra 10.4 inches bumper to bumper, stretching 1.4 inches wider, and standing 1.6 inches taller. This is a big truck. 

Here is what we know so far:

The Michigan-built 2020 Silverado HD will be offered with two new powertrains. 

The standard engine is a 401-hp, 6.6-liter direct-injection V8 with a six-speed transmission. The other choice is a 445-hp, 6.6-liter turbodiesel V8 engine with an Allison 10-speed transmission. This tow-ready engine produces a prodigious 910 lb.-ft. of torque—the same amount of torque as the current diesel.

We tested the current Silverado HD with a turbodiesel engine and Allison transmission combination. It sprinted from 0 to 60 mph in 8.2 seconds and returned 14 mpg overall in our fuel-economy tests. Our tested truck benefited from smooth power and easy towing. It proved to be a rough-and-tumble workhorse, with enough creature comforts and amenities to appeal to a modern, connected driver, such as an intuitive infotainment system with Android Auto and Apple CarPlay compatibility. Plus, available safety features include forward collision warning, lane departure warning, and front and rear park assist.

Chevrolet says modifications throughout enable the new truck to boast a 52-percent increase in maximum tow capacity, for up to 35,500 pounds on regular cab, two-wheel-drive, diesel 3500 dualies. Maximum payload for the 3500 is 7,466 lbs. for the gas dualie. The max payload for the 2500 HD gas version is 3,991 lbs. 

A variety of features aim to make trailering easier and safering, including automatic parking brake, a hill hold assist, trailer sway control, a transparent trailer view camera that allows the driver to see through the trailer, and steering assist that compensates for a trailer. 

The Silverado HD goes on sale in summer 2019.
