GMC has just tipped its hand on all the changes to the company’s lineup of trucks and crossovers for 2020. That includes new trims, new content, and, of course, the all-new models we already know about.

The all-new model is the 2020 Sierra HD. We drove that truck a couple of months back, but the highlights are the all-new body and frame with class-leading max towing capacity. There’s also up to 15 camera views and extensive trailer integration. GMC’s AT4 trim is new to the HD and is quickly expanding across the GMC lineup. It’s a more luxurious off-road model, and it comes with GMC’s MultiPro configurable tailgate.

For 2020, GMC’s smallest crossover gets a new safety package. The Terrain adds GMC Pro Safety standard on all trims. That means emergency braking, forward collision alert, lane-keeping with lane departure warning, a following distance indicator, front pedestrian braking, and Intellibeam headlights. More active safety gear, including radar cruise and rear cross-traffic alerts are part of the Driver Alert Package option. The Terrain Black Edition with 19-inch wheels and other dark trim has been renamed Terrain Elevation.

The refreshed 2020 GMC Acadia arrives later this year. It gets a new nose with new tech and interior refinements. The new Acadia gets an AT4 trim, but there’s also a new 2.0L turbo engine standard on SLT and an option on SLE FWD. It joins the 2.5L four and 3.6L V6, and all three get a nine-speed auto.

GM’s 3.0L inline-six diesel finally arrives to the Sierra 1500 for 2020. The carbon fibre bed is more widely available, as is the 10-speed auto. GMC has also upgraded the ProGrade Trailering System to have 15 camera views including a transparent trailer view. The 2020 Sierra also gets radar cruise.

The smaller Canyon pickup adds a new tire fill alert. It’ll give you an audible and visible alert when you’re filling up your tires with a compressor. There’s a new locking tailgate on the options list as well. The All Terrain trim gets a Driver Alert package, forward collision alert, and lane departure warning.

Missing from the info are GMC’s biggest SUVs. The Yukon and Yukon XL. Most likely they’re not getting any changes because with the arrival of the new Sierra pickups the big SUVs are also due for replacement. We’re not sure when those will be shown, though.
