The fourth-generation GMC Sierra 1500 first introduced in 2019 gets a first-year refresh, with a number of exciting changes and upgrades. Undoubtedly, the biggest news is the addition of a new 3.0-liter turbodiesel option, but other changes include the option for adaptive cruise control, trailer and bed-view cameras, and a 10-speed automatic transmission.

Several powertrains are available to match your hauling and towing needs, and the bed capacity is great. Passengers in both the front and the rear get a fantastic amount of space, and the new touchscreen display is easy to use, quick to respond, and attractive.

Performance and Powertrains

You now have no less than five potential powertrains from which to choose on the GMC Sierra.

  • The base engine is a 4.3-liter V6 that’s capable of outputting 285 horsepower.
  • A step up is a 2.7-liter turbo-4 that outputs 310 horsepower. It’s paired with an 8-speed automatic and will get you around 21 miles to the gallon.
  • The 5.3-liter V8 is perhaps the ‘sweet spot’, offering 355 horsepower and the maximum towing power of 11,000 pounds. Paired with 4-wheel-drive, it gets a 10-speed automatic transmission.
  • Need more V8 grunt? Upgrade to the 6.2-liter V8 that outputs 420 horsepower. It drains the tank a bit quicker than the previous powertrains, at 17 miles to the gallon, and is only available in a 4-wheel-drive configuration.
  • New this year is the highly anticipated 3.0-liter inline-6 turbodiesel. It’s the quietest of the bunch and the most efficient at around 30 miles to the gallon. It’s also the smoothest ride.

Payload and Towing

The 2020 Sierra 1500 diesel can carry up to 1,830 pounds on its back, and drag 9,100 pounds behind it. Most customers will never plan to tow over 10,000 pounds, but if you need to do so, you can move up to the GMC Sierra 2500 or GMC Sierra 3500.

One of the cool features that make the Sierra 1500 (and Chevrolet Silverado HD) stand out is the optional six-function MultiPro tailgate. You get this as standard on the SLT and higher trims, and optional on lower trims. This tailgate essentially has two gates, with a smaller inner gate hinged inside a conventional gate. This allows the tailgate to act as a bed extender, seat, workstation, two-tier storage, and an entry step.

Another award winner is the trailering tech on the 2020 GMC Sierra 1500 that makes life easy. The trailering app helps you test all of your trailer’s lights, temperate, and tire pressure before you set off, and the invisible trailer feature lets you see exactly what’s behind your trailer as if it wasn’t there. Another camera view lets you see down both sides of the trailer at the same time on the 8-inch screen.


The 2020 GMC Sierra 1500 has seen a boost in style, with a new headlight, multi-block grille, and bumper design. Choose the Denali trim for the full chrome effect; with this luxury trim, you get chrome from the mirror caps and fenders to the grille and the 22-inch wheels. The off-road specced AT4 version is equally dashing, but it presents itself in a more menacing way with black chrome pieces.

Three cab styles are available (regular, extended, and crew cab), and three bed lengths, depending on the configuration.

Interior and Comfort

One of the best reasons to choose the 2020 GMC Sierra 1500 is its excellent spacious interior. The most popular option is the 4-door crew cab that offers so much space to stretch out.

Both front and rear seats are massive, and there’s so much more headroom and legroom than in previous GMC models. Interior storage abounds, with a huge center console that will fit tools, laptops, or tablets. USB charge ports make keeping your devices powered easy.

Trim Levels

There are a huge number of configuration options available for the 2020 GMC Sierra. Let’s just say that whatever features you desire you’ll find them available on the Sierra 1500.

The base model has power features, a USB port, and a 7-inch touchscreen.

There’s also the SLE and Elevation, but most shoppers will upgrade to the SLT that adds 18-inch wheels, upgrades to an 8-inch touchscreen, adds leather upholstery, the MultiPro tailgate, and an HD rearview camera.

Luxury full-size truck buyers will opt for the Denali, which includes such opulence as 22-inch wheels, open-pore wood trim, a navigation system, adaptive suspension, front bucket seats, and a surround-view camera system.

Finally, the AT4 trim is the best option for off-roading, with its 2-inch suspension lift, off-road suspension, and tougher hardware.
