2020 Chevy Silverado 3500HD Review

Four-wheel drive is optional, as is a dual rear-wheel setup to increase the max towing capacity. A new 6.6-liter gasoline V8 (401 hp, 464 lb-ft) replaces the old 6.0-liter gasoline engine, while the 6.6-liter diesel V8 (445 hp, 910 lb-ft) carries over. These are available on all trims. Both engines are paired with a new 10-speed automatic transmission.

The Work Truck model is exactly that: a no-nonsense vehicle aimed at customers looking for a heavy-duty pickup with relatively few creature comforts. Features are limited but include vinyl flooring, a 7-inch touchscreen, and Apple CarPlay and Android Auto smartphone integration. You're limited on options, and most of the trim and bumpers are black.

Stepping up to the LT adds standard equipment such as an additional USB ports, a Wi-Fi hotspot, power door locks and chrome bumpers. More importantly, the LT opens up the number of optional packages you can choose from.

The LTZ trim takes things even further, adding a number of standard features that are optional or unavailable on the Work Truck and LT models. These include LED headlights, an EZ Lift tailgate, dual-zone climate control, and variable assist steering that adjusts the setting based on speed and road conditions. Look for the optional Safety Package II package that offers features such as forward collision alert and automatic emergency braking.

The Chevrolet Silverado HD High Country is the top model in the lineup. In addition to unique styling details, the High Country's standard equipment includes a power tailgate, a Bose audio system, leather upholstery, and heated and ventilated front seats.
