2020 Chevrolet Silverado HD — Photos

Chevrolet has released the first images and details of the 2020 Silverado HD, and the brand says that the new heavy-duty trucks will be "the most capable and most advanced" ever.

At the rear, similarities to the 1500 are more pronounced, but the tailgate is less chiseled, and the bed itself is boxier. According to Chevy, the HDs have a taller seating position and three additional inches of legroom compared to the 1500.

According to Chevy, the only body panel that the new Silverado HDs share with the regular 1500 is the roof; everything else is totally new. Like the 1500, the HD trucks have a funky, alien-like front end, but the aggression is turned up a notch, and it works well.

As with the current Silverado HD, two powertrains are on offer: a gasoline-drinking V-8 and a turbo-diesel V-8. Full specs aren't given for either engine, but Chevrolet says the gas engine is completely new and will be paired with a six-speed automatic transmission; the current V-8 is a 6.0-liter Vortec unit that makes 360 horsepower.

The Silverado 2500HD and 3500HD will make their formal debuts at the Chicago auto show in February, and the trucks will go on sale in mid-2019. Look for the heavy-duty versions of the GMC Sierra to be revealed soon as well, with many of the same cosmetic and mechanical upgrades as these Chevrolets.
