For 2020, the GMC Sierra gets a slew of new technology as well as a new engine offering.

The competition to produce the best-equipped pickup truck continued to get tighter today with GMC’s announcement that its “taking premium to the next level” for its 2020 Sierra 1500.

GMC’s full-size light-duty pickup can now get a slew of new options to take it up a notch, including expanded availability for its carbon fiber bed, 3.0-liter Duramax turbo-diesel and 10-speed automatic transmission, plus additional technology like Adaptive Cruise Control – Camera.

While options are great, functionality is still king among truck users and GMC is looking to make a statement in that arena too. For 2020, the Sierra 1500 will be available with the upgraded ProGrade Trailering System introduced earlier this year on the 2020 Sierra HD. The updated system offers 15 camera views – the class leader – plus an in-vehicle Trailering App which has been enhanced to simplify the trailering process.

“The Sierra is delivering the tech customers want in the light-duty truck market, and the 2020 model demonstrates that Professional Grade means never slowing down,” said Duncan Aldred, vice president of Global GMC.

“In just its first year on the market, the 2019 Sierra introduced the available, industry-first CarbonPro Bed and MultiPro tailgate. The truck’s 2020 updates show how the Sierra continues to raise the bar year in and year out.”

For 2020, Adaptive Cruise Control is available on SLT, AT4 and Denali trim levels of the Sierra light-duty. The system uses a single high-mounted camera behind the rearview mirror and can bring the Sierra to a complete stop.

The truck also gets some powertrain updates for 2020. The brand’s 10-speed automatic transmission is now offered with the 5.3-liter V-8 with Dynamic Fuel Management. The pairing will be standard on the Sierra Denali and Sierra AT4 and available on all four-wheel drive Sierras with the SLE trim level and higher, the company said.

Additionally, the Sierra can now be had with 3.0-liter Duramax inline-six turbo-diesel engine, which is mated to the 10-speed automatic. The 3.0-liter Duramax produces an SAE-certified 277 horsepower and 460 lb-ft of torque, which officials point out is tops in the segment.

For 2020, the Duramax is now available in conjunction with the CarbonPro Edition of the Denali and AT4 models. Beyond the CarbonPro Edition, the Duramax is also available on Denali, AT4, SLT, Elevation and SLE models.


The Sierra continues to offer a multitude of innovative features, including:

  • World’s first MultiPro Tailgate – The most innovative pickup tailgate ever, with six unique functions and positions offering enhanced second-tier loading and load-stop solutions, a standing workstation and easy access to items in the box.
  • GMC-exclusive CarbonPro Pickup Box – The industry’s first carbon fiber pickup box, developed to increase durability, efficiency and functionality while offering best-in-class dent, scratch and corrosion resistance.
  • Multi-Color Head-Up Display – This segment-first Head-Up Display projects key, customizable vehicle data on the windshield on a 15-inch- diagonal display.
  • Rear Camera Mirror– The segment-first Rear Camera Mirror offers an available dual-function interior rearview mirror with a camera view display that provides a wide view unobstructed by common visual obstructions like occupants or cargo. This next generation system features the ability to tilt or zoom the view.

The 2020 Sierra Denali features an Adaptive Ride Control suspension system designed to provide premium driving refinement with exceptional responsiveness. It provides continuous ride damping by employing sophisticated sensors to monitor road conditions and chassis responses in real time, enabling adjustments to active dampers every two milliseconds.

GMC officials didn’t offer any pricing or timeline for when these new offerings will be available to consumers.
