Picture of 2020 GMC Sierra 1500

The new Sierra 1500 AT4 is far too nice to be a work truck, but it represents what modern pickup shoppers seek.

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?

Absolutely stunning vehicle. Pure luxury pick-up truck. Serious power, w/a 6.2L V8 engine; smooth, wonderful ride, lots of driver convenience & safety features; comfortable seating, roomy cab interior....I could go on. GMC has left nothing out of their Sierra Denali line. Beautiful truck - everyone Ive talked to feels the same. Commanding presence on the road. Tops Dodge Ram & Ford models, in my opinion. I have a 2020 model. The 2023 model tops even THAT!!!
