2019 GMC Sierra Sports New Materials and a Diesel


Following on the heels of its cousin the Chevrolet Silverado's release, GMC took the wraps off its 2019 Sierra, with an obvious focus on the upscale SLT and Denali models. That's no surprise: nearly 30% of all GMC sales last year wore Denali badging — a record high — and Denali/SLT models now account for 87% of Sierra crew cab pickup sales.

Both those models are expected to go on sale this fall. For motivation, the Sierra gets updated 6.2L and 5.3L V8 engines, which feature start-stop functionality and, depending on power demand, can now shut down up to seven of their cylinders when running for fuel savings. Also new for 2019 is a 3.0L inline 6-cyl. turbo diesel engine option; the bigger V8 and diesel will be mated to a 10-speed automatic.

The 2019 Sierra sets itself apart from its cross-platform brethren with some advanced and distinctive features, and again, that's mainly concerning standard equipment on the Denali and SLT that's optional otherwise. Start with a rear bumper with integrated steps built into it and head slightly north to the truck's snappy new tailgate, which according to General Motors required more design and validation hours than any the automaker has produced prior to this.
