We've got more details about the 2019 GMC Sierra Denali now that it's rolling into dealerships, starting with its floor price of $56,195, including destination fee, for the rear-wheel-drive models. That's a jump of $1,900 over the previous generation of its premium full-size pickup. Four-wheel-drive models start at $60,295.

The crew-cab truck has grown in every dimension as well, adding about 4 inches to the wheelbase, nearly 2 inches in length and 1.2 inches in width. There's also nearly 3 inches more rear legroom. Bed options are 5-foot-8 or 6-foot-6.

There are three engine options. Two are carryovers from 2018: a 5.3-liter V8 that sends 355 horsepower and 383 pound-feet of torque through an eight-speed automatic transmission, and an available 6.2-liter V8 that makes 420 hp and 460 lb-ft of torque and mated to a 10-speed automatic. Both come with GM's dynamic fuel management cylinder-deactivation technology to optimize power and fuel efficiency. A new 3.0-liter turbodiesel paired with a 10-speed automatic is expected in early 2019. The EPA hasn't yet released official fuel economy ratings, but GM estimates them at 17 miles per gallon in the city and 23 mpg on the highway for the two-wheel-drive versions, and 15/21 in four-wheel drive.

The truck gets adaptive ride control which can adjust the dampers every 2 milliseconds based on real-time monitoring of the road and driver inputs for improved ride and handling. A new traction select system adjusts the transmission shift points, throttle mapping and StabiliTrak to tailor performance to different terrain or weather conditions.

Inside the crew cab, there's new Forge leather-appointed seats, open-pore wood trim and dark finished aluminum decor, plus an 8-inch-diagonal HD color touchscreen with embedded navigation and Apple CarPlay and Android Auto compatibility. Most of the other new stuff we've covered before, including new C-shaped LED headlights and LED tail and fog lamps, optional 22-inch wheels, full-color head-up display, trailer-hitch assist apps and cameras, and rear-camera mirror. The truck also loses up to 360 pounds from the outgoing model via a scratch- and dent-resistant carbon-fiber bed box that replaces steel, and use of aluminum in the doors, hood and tailgate.

The big news is the Denali's MultiPro Tailgate, which has six different configurations and uses aluminum to save weight, and can be used to extend the bed, drop to allow easier access, provide a work surface or be used as a step to access the bed. You can see how it works in the video below:
