GMC has given one last tease before officially debuting its all-new 2019 Sierra 1500 pickup on March 1. The darkened images show the headlight and taillight profiles, with not much else to see. GMC was smart enough to thwart efforts in Photoshop to lighten the images; there’s just no data in the shadows.

Nevertheless, we can see the taillights have a modern appearance, yet one familiar to GMC. The C-shaped LED lights appear to be housed in clear lenses, similar to the taillights found on the current Sierra, Canyon, and Yukon models.

Aside from the taillights, we know the GMC Sierra will share the same underpinning, drivetrain components, and interior design as its corporate twin, the 2019 Chevrolet Silverado 1500. The truck will have a stronger frame, updated suspension parts, and use GM’s new high-tech Dynamic Fuel Management technology. DFM allows both the 5.3-liter and 6.2-liter V-8s to individually control cylinder firing operations depending on engine loads. During light loads like coasting down a hill, the engine is capable of running on a single cylinder. When power is needed, the DFM system provides fuel and spark to all eight cylinders. GM’s new 10-speed automatic transmission will be present, too.

GMC will likely debut the Sierra’s entire lineup, from the bare-bones WT to the range-topping Denali trim. The Denali has been a veritable gold mine for GMC over the last 10 years, so we fully expect much hubbub to be made over the trim line.

After its March 1 debut, the 2019 Sierra will go on sale toward the end of summer in 2018. Expect pricing to increase slightly over the current model.
