Revamped Acadia And Redesigned Sierra HD Headline GMC’s Updated 2020 Lineup

GMC is entering the 2020 model year with a host of new, redesigned and updated models.

Starting with the Terrain, all trims now come equipped with the GMC Pro Safety package. It includes IntelliBeam headlights as well as driver assistance systems such as automatic emergency braking, front pedestrian braking, forward collision alert, following distance indicator and lane keep assistance with lane departure warning.

The Terrain Denali has also been updated as it receives a revised suspension with new internal valves that promise to deliver a “more refined ride.” The model also gains a new Premium Package which combines the Advanced Safety Package with the Comfort Package. It adds features such as adaptive cruise control, heated / ventilated front seats and heated rear seats.

While GMC didn’t mention it, the 1.6-liter turbodiesel engine has been dropped due to low demand.  The four-cylinder produced 137 hp (102 kW / 139 PS) and 240 lb-ft (325 Nm) of torque.

Lastly, the Terrain Black Edition has been renamed the Terrain Elevation Edition. It features dark exterior accents and 19-inch wheels with a “glass black” finish.

2020 Acadia

Sticking with crossovers, the Acadia has been extensively updated for 2020. The facelifted model features a more rugged appearance thanks to modified fascias and a revised grille that draws inspiration from the Sierra. The crossover also has new headlights, an updated infotainment system and a new nine-speed automatic transmission.

Under the hood, there’s a newly available turbocharged 2.0-liter four-cylinder engine that produces 230 hp (172 kW / 233 PS) and 258 lb-ft (350 Nm) of torque. It slots in between the naturally aspirated 2.5-liter four-cylinder and the more powerful 3.6-liter V6.

2020 Canyon

The on the truck side, the 2020 Canyon largely carries over. However, the model features a revised color palette that now includes Carbon Black Metallic.

Elsewhere, there’s a newly available remote locking tailgate and a newly standard Tire Fill Alert system which provides an audible and visual warning when a tire needs air. The Canyon All Terrain can also be equipped with new features such as forward collision alert and lane departure warning.

2020 Sierra

The Sierra was redesigned for 2019, but that doesn’t mean there aren’t any changes this year. The big news is the availability of a 3.0-liter Duramax turbodiesel engine that produces 277 hp (207 kW / 281 PS) and 460 lb-ft (624 Nm) of torque. It is connected exclusively to a ten-speed automatic transmission.

Other updates include adaptive cruise control and expanded availability of the carbon fiber bed. A ten-speed automatic transmission is also offered on additional models and the truck can be equipped with a ProGrade Trailering system which features a transparent trailer view mode.

2020 Sierra HD

Last but not least, the Sierra Heavy Duty has been redesigned for 2020. Introduced earlier this year, the truck has a 6.6-liter Duramax turbodiesel engine that produces 445 hp (332 kW / 451 PS) and 910 lb-ft (1,233 Nm) of torque. It is connected to a ten-speed Allison automatic transmission which can send power to an optional four-wheel drive system.

Of course, heavy duty trucks are all about towing and this is where the Sierra HD excels. Depending on the model and configuration, the truck can tow up to 35,500 lbs (16,102 kg).

GMC didn’t mention any updates to the Yukon or Yukon XL, but redesigned versions will be introduced shortly.

    So the 2020 Canyon looks just like the 2015 Canyon. Are they following Nissan’s business practices?

    • FordMopar

      Basically one and done. Typical GM!

    Save for the soon-to-be-redesigned Canyon and Yukons, GMC has headed down the wrong path with those hideous front ends. Ruined the Acadia but good. Come to think of it, only Buick has decent front ends over at GM.

  • Dennis Scipio

    I don’t really like the front end of the facelifted Acadia, the pre-facelift look better. The front on the Sierra looks better.

    • FordMopar

      I thought the pre-facelift look was too feminine looking. Too soft. This new 2020 is how GMC should have their vehicles look like. More squarish looking. Leave the soft feminine looking for Chevy and Buick.

    That grille doesn’t work for the Acadia

  • Harry_Wild

    Acadia needed the 9 speed transmission. I think it a little narrow inside for my liking but definitely more attractive on the outside now in the 2020 model. Same color choices for the interior too!

    • Joe E

      Agree that the 2020 Acadia looks better. The outgoing version looked too….feline?…something was off. It didn’t fit the brand’s industrial image. I realize they essentially tacked a window A/C unit onto the front, but it looks better.

  • Timothy Pender

    All well and fine with new packaging on the Acadia Denali as long as GMC took care of a few basic things lacking in my 2017

    Did they do anything to fix the creaks heard the first 5 miles of driving from the doors? How about the A/C that is either warm or Arctic with no modulated temperature? How about the rear view backup camera that is grainy during the day and washed out at night? Sunroof shade? Does it still rattle?

    Having said that, the MPG is excellent on highway, seats are very comfortable and room is great in 4 passenger configuration.

    What really is the point of GMC? What does it offer that a Chevrolet does not? It’s amazing that GM puts money into what is essentially slightly altered versions of the same cars. They have no prestige brands, no World Brands and there is literally no WANT one factor among anything GM put’s out except perhaps the new Corvette. Even that is notable only for the money vs Price factor. Aesthetically it’s a hot mess. I suspect GM will go Bankrupt again. Even FCA has more desirable and marketable brands – Jeep, Alfa, Ram and Maserati. GM has nothing.

    • Navigator Navy✓ᵛᵉʳᶦᶠᶦᵉᵈ🍑

      Because GMC is upscale rather Chevrolet is value. Multi-pro tailgate is not available yet on Silverado.

    The state of those grilles…
