Why it stands out

The 2021 Chevrolet Silverado 3500HD stands out as a heavy-duty truck that is built around capability first. It wears the fourth-generation Silverado HD’s aggressive styling, with a huge bluff front end that makes it hard to mistake for anything else on the road. More importantly, it backs up that look with serious numbers: maximum towing is listed at 16,300 kilograms, payload can reach 3,300 kilograms, and even the lowest-rated four-wheel-drive 3500HD can still manage 8,000 kilograms of trailer pull with a conventional hitch. For buyers who need a truck that can handle major towing and hauling jobs, that combination is the core appeal.

Chevrolet also gives the 2021 Silverado 3500HD a strong mix of engines and hardware. The standard 6.6-litre gas V8 makes 401 horsepower and 464 pound-feet of torque, while the optional Duramax turbodiesel V8 produces 445 horsepower and 910 pound-feet of torque. Both engines use an Allison ten-speed automatic transmission, and the diesel can be paired with integrated Power Take-Off for running large accessories. The truck is offered in WT, LT, LTZ, and High Country trims, with rear-wheel drive standard, four-wheel drive optional, and a dual-rear-wheel setup available for added stability. Chevrolet also gives it useful work-focused features such as 12 cargo tie-downs, the Multi-Flex Tailgate, and a power up/down tailgate, along with trailering tech that includes detailed camera views and an infotainment display designed to make manoeuvring a large truck easier.

There are some trade-offs, though. The cabins have been criticised for being too basic compared with Ford and especially Ram, and the truck’s driving dynamics and fuel economy lag those rivals as well. The 2021 model also sits in a price range that reflects its size and equipment, so it is not a bargain purchase. Even so, for buyers who value towing strength, available diesel muscle, and a broad set of hauling and trailering tools, the Silverado 3500HD remains a compelling choice.
