The all-new 2019 GMC Sierra pickup truck made its debut in Detroit with new features including a multi-function tailgate, enhanced trailering system, diesel engine, and industry-first carbon-fiber box.

Available in SLT and Denali trims, the Sierra enters its second generation with a complete redesign that starts with exterior styling. There’s a larger, more upright grille, taller hood, and wheels that are moved closer to the corners to enhance the Sierra’s stance. GMC’s signature C-shaped lighting is more pronounced, and the Denali trim includes LED headlights, tail lights, and fog lights. There’s more prominent badging on both trims, and the Denali gets a new tailgate nameplate in a bold, block-style typeface.


The Sierra boasts a more refined interior with best-in-class front legroom and headroom and a higher seating position to give the driver a better view. There are exclusive Denali materials including premium leather seating, open-pore wood trims, and dark-finish aluminum accents. Those in back will find plenty of room with the crew cab gaining nearly 3 inches of legroom over the outgoing model. The rear outboard seat backs also conceal storage ideal for holding tablets, laptops, or smaller items like umbrellas.

The Sierra Denali has features that make it more comfortable, more connected, and easier to use than ever. There’s a 3×7 multi-color heads-up display and an available rear camera mirror. This dual-function mirror uses cameras rather than the traditional line of sight behind the driver, so the driver’s view isn’t blocked by rear seat occupants or cargo. It uses a high-resolution camera that lets the driver tilt or zoom the display for the perfect view. A surround vision camera that displays an overhead view of the area around the Sierra onto the infotainment screen is also available.

When it comes to cargo, the 2019 GMC Sierra has a unique MultiPro Tailgate as a standard feature. This industry-first tailgate design has six unique functions and positions, including a standing workstation mode and enhanced options for loading and accessing items in the box.


A step entry and egress mode pairs with an assist handle to offer step and seated functionality with a 375-pound maxium weight. Two buttons on the tailgate handle make using the tailgate easier by allowing quick inner tailgate release. Dealer Specials:

The cargo box of the all-new Sierra has a best-in-class 63 cubic feet for the short box with additional tie-downs and an available 110-volt power outlet. It’s made of high strength steel that’s 50 percent stronger than the current model.

Also, coming later in the year, the Sierra Denali will be available with a CarbonPro carbon-fiber box. It replaces the usual steel inner panels with a lightweight carbon fiber composite that resists dents, scratches, and corrosion.

“In 116 years of making GMC pickup trucks, our industry-first carbon-fiber box is the toughest and most durable pickup box we have ever made,” said Duncan Aldred, vice president of Global GMC.

The Sierra will also offer GMC’s new ProGrade Trailering System as a standard feature. It includes an all-new app that has a pre-departure checklist, maintenance reminders, trailer light test, trailer electrical diagnostics, trailer tire-pressure monitoring, and temperature monitoring. Many of these functions can also be accessed through the MyGMC app for compatible Android and iOS devices. Hitch guidance with hitch view and auto electric parking brake further take the work out of hitching up a trailer through cameras that make positioning easier.

Power for the 2019 GMC Sierra will come from new versions of the 6.2-liter and 5.3-liter V8 engines with auto stop/start technology and the ability to operate on anywhere from one to eight cylinders for better fuel efficiency. These engines will be joined by an all-new 3.0-liter six-cylinder turbo-diesel that will be paired to a 10-speed automatic transmission.


The all-new 2019 GMC Sierra will go on sale this fall with pricing and additional details revealed closer to production.
