KEY FEATURES
The next generation 2021 Sierra's bigger cab and box creates a dominating presence.
With a longer wheelbase, the wheels are located closer to the corners to create a bold stance and offer better use of cabin space. A larger grille helps supply more airflow to the powerful engine.
The GMC Sierra's available dual function mirror can be used as a conventional rear-view mirror or as a camera-based rear-view mirror that helps drivers see around potential vision obstructions such as rear head restraints.
Compared to a traditional interior rear-view mirror, this mirror display provides a wider, less obstructed field of view to assist when driving, changing lanes, and checking for vehicles and traffic conditions. It offers zoom, brightness and vertical tilt driver adjustments.
The new GMC Sierra provides more passenger room, especially in the back seats.
Drivers enjoy a higher, more confidence-inspiring seating position. The cabin features more refined materials and premium details, like real aluminum trim and open pore wood accents.
Rear seat passengers will be more comfortable with new, standard rear HVAC outlets. And there's even some clever new rear seat back storage available.
The technologically advanced 15-inch diagonal projected Head-Up Display shows key information that sits low on the windshield, allowing the driver to stay informed while clearly seeing:
- Speed
- Tachometer
- Audio
- Navigation
- Low fuel warning
- Phone
- Safety alerts
- Off-road inclinometer

AROUND THE SIERRA 1500
FRONT AND REAR PARK ASSIST
When driving below 8 km/h, this feature provides distance-to-object alerts to help the driver park and avoid nearby detected objects directly ahead of or behind the vehicle during low-speed maneuvering.
HD SURROUND VISION
When driving slowly, this feature can provide the driver a 360-degree view of the scene around the truck on the infotainment screen.
TRUCK BOX
With more cargo volume, due to a wider inner box, Sierra beats the competition. Cargo volume is now at 1781 L (62.9 cu.ft.) with short box and 2,030 L (71.7 cu.ft.) with the standard box. 12 total cargo tie-downs—rated up to 227 kg (500 lb.) per corner.
MULTIPRO TAILGATE
With improvements in loading, unloading and accessing the cargo box, the six distinct functions designed into the available GMC MultiPro Tailgate represent the pinnacle of GMC innovation. Available on SLT, AT4, and Denali trims.
WIRELESS CHARGING PAD
When you’re on the road, the 2021 GMC Sierra offers an available wireless charging pad, located within easy reach near the cupholders, keeps your compatible smartphone charged and ready.
CONNECTED ACCESS
There are customers who don’t use a smartphone, and therefore wouldn’t benefit from the MyGMC mobile app - but now, some of that technology is available right here with in-vehicle apps. Available on the base model.
