2020 GMC Sierra 1500 Reviews Summary

It’s no surprise that trucks have improved and evolved over the years. After all, think about an average sedan from the early 1980s compared with a modern 2020 vehicle. Yet because pickup trucks are largely confined to a common shape, many shoppers are still surprised to see how nice they have become. This is especially true if your memory of trucks includes a vinyl bench seat.

Modern trucks heavily incorporate utility-minded innovations. Cargo-management tools, side steps, and bed steps make for a more useful vehicle. Under the hood, turbocharging has made V6 and even 4-cylinder engines usable, delivering the power of the larger engines they aim to supplant. And finally, cabins have become nicer and more comfortable than previously imagined for a pickup.

This evolution speaks to how trucks get used as family vehicles that can also do work. There are the work trucks, but there are also trucks like the 2020 GMC Sierra 1500, which has many of the creature comforts of SUVs and crossovers. It says “I want a truck, but I could probably be used as a minivan.”

But somewhere in the middle sits Sierra's AT4 trim. It’s comfortable, sure, but it’s also capable. Does that make it a good fit for both the worksite and the daily commute?

2021 GMC Sierra 1500 Reviews Summary

GMC is the “professional grade” brand at General Motors, but that’s just marketing mumbo jumbo. The 2021 GMC Sierra 1500 is the same thing as a Chevrolet Silverado 1500, but with different styling and a handful of unique features, like an optional carbon-fiber composite cargo bed. This year, GMC makes several changes to its full-size light-duty pickup truck, none of them earth-shattering. This remains a fundamentally appealing truck in need of attention to the details.
