SPIED – 2020 Chervolet Silverado HD and GMC Sierra HD

Whenever a truck manufacturer reveals a new light-duty pickup, as both Chevrolet and GMC did this year, we know it’s only a matter of time before the 1/2-ton gets an HD variant. That’s why we’re not surprised to see GM engineers rolling around in a fleet of heavily camouflaged fullsize trucks, almost certainly versions of the 2020 Chevrolet Silverado HD and GMC Sierra HD. Seen in a variety of body configurations, it’s clear that GM wants its big trucks to be used in many different vocations.

2020 Chevrolet Silverado HD

Although it’s difficult to see through the thick plastic that wraps these trucks, it’s obvious they’ll adopt some of the styling features of their respective little brothers. The Chevrolet Silverado 2500HD, seen here in Double Cab form, looks like it’ll acquire the smaller truck’s rounded wheel arches and architectural styling features. But as we saw with the Silverado HD teaser of a few weeks ago, it gets multi-element headlamps bisected by a large grille bar, a bolder front end treatment than what’s applied to the new 1500. Taillights for the HD will likely echo the notched units found on other Silverados.

2020 GMC Sierra HD

The GMC Sierra HD will probably look more like its 1500 counterpart than the Silverado HD does. Both Silverado and Sierra were spotted with cobbled-together headlamp units, but the shape of the Sierra HD’s light openings more closely matches that of the smaller Sierra 1500. The grille, upsized and emboldened in the big-truck style, nevertheless features a similar notched-shield shape as the light-duty pickup. Expect asymmetrical wheel openings to more easily distinguish the GMC from its Chevrolet cousins.

Finally, GM has seen fit to do away with the current trucks’ low-hanging DEF tanks. On the 2020 GMC Sierra HD and Chevrolet Silverado HD, the DEF tank is located almost entirely above the level of the frame rail, where it’s better protected from trail hazards and road debris. We expect the 2020 heavy-duty trucks to retain the same powertrains as their predecessors, with a standard 6.0L gasoline V-8 with 360 hp and 380 lb-ft joined by an optional 6.6L Duramax L5P V-8 providing 445 hp and 910 lb-ft. Expect the former to run on gasoline, E85, or a mix of the two, while the latter should offer B20 biodiesel compatibility. And as expected in the pickup segment, we’re sure GM will uprate the trucks’ towing and payload capacities by a fair bit to keep up with the Ford F-350 and Ram 3500’s stratospheric ratings.

Expected for a debut at the 2019 North American International Auto Show in Detroit, the 2020 Chevrolet Silverado HD and 2020 GMC Sierra HD will likely go on sale later that year, doing battle with the likewise-new Ram Heavy Duty. Both all-new trucks will bring the fight to Ford’s F-Series Super Duty, which should receive a midcycle facelift by 2020 or 2021.
