There are lots of changes across the 2020 GMC lineup.
GMC is introducing a lot of changes for its 2020 model lineup, with new models and smart new tech. The GMC Terrain, for example, has been updated for 2020 with a slew of new standard safety features. As standard, all trim levels now come with Automatic Emergency Braking, Forward Collision Alert, Lane Keep Assistance with Lane Departure Warning, Following Distance Indicator, Front Pedestrian Braking, and IntelliBeam Headlamps.
Complementing the new standard safety tech is an optional Driver Alert Package that includes Adaptive Cruise Control, Lane Change Alert, Side Blind Zone Alert, Rear Cross Traffic Alert, Rear Park Assist and Safety Alert Seat.
Also joining GMC's new model lineup is the faclifted 2020 Acadia. Due to go on sale this summer, the 2020 Acadia features a fresh design with a bold new grille, new front, and rear facias, and LED lights, along with a more refined interior. Standard driver assists now include Lane Change Alert with Side Blind Zone Alert, Rear Cross Traffic Alert and Rear Park Assist.
The first-ever Acadia AT4 is also available with a more aggressive exterior and a new 2.0-liter turbocharged engine standard on SLT models that produces 230 hp and 258 lb-ft of torque. Other engine options include a naturally aspirated 2.5-liter four-cylinder and a 3.6-liter V6. A new nine-speed automatic transmission is offered as standard.
Denali models add Front Park Assist in addition to the Rear Park Assist, and the new Denali Premium Package combines the Advanced Safety Package and Comfort Package to include Adaptive Cruise Control, ventilated driver and front passenger seats, and heated rear seats, among other premium features. An upgraded suspension also distinguishes the Denali models, which include new internal valves for a more refined ride and unique spring isolators that reduce road noise.
The Terrain Black Edition has also been renamed the Terrain Elevation Edition. As before, it adds 19-inch glass-black wheels and darkened details, and is offered with Summit White, Graphite Gray Metallic or Ebony Twilight Metallic paint.
The updated 2020 Sierra offers a 3.0-liter Duramax turbo-diesel engine that produces 277 hp and 460 lb-ft of torque paired with a 10-speed automatic transmission. The CarbonPro Edition is also available for the first time with a carbon-fiber bed available on AT4 and Denali models. Other available new tech includes an upgraded ProGrade Trailering System with 15 total available camera views and a transparent trailer view, and Adaptive Cruise Control.
The all-new Sierra Heavy Duty also started production earlier in the summer, which can tow up to a class-leading 35,500 pounds on 3500 Regular Cab, long box, two-wheel-drive, DRW diesel models.
Powering the heavy-duty truck is a 6.6-liter Duramax turbodiesel engine that produces 445 hp and 910 lb-ft of torque, paired with a a ten-speed Allison automatic transmission.
Finally, the smaller, mid-size GMC Canyon pickup has been given a comparatively minor update for 2020 with new features including a standard Tire Fill Alert, a newly available remote locking tailgate, a Driver Alert package, Forward Collision Alert, Lane Departure Warning, and a Carbon Black Metallic color option.
