2021 GMC Sierra, perfect for heavy duty tasks
Trailer Length Indicator: New for 2021, when enabled and driving forward with the turn signal activated, the center console screen displays a red overlay twice the length of the compatible trailer and shows when other vehicles are present and may interfere with a lane-change maneuver. New for 2021, Jack-Knife Alert tracks the position of the compatible trailer in relation to the vehicle. If the front of the trailer approaches the rear of the vehicle, an alert is displayed when there may be a potential jack-knife situation.
Rear Trailer View has been enhanced to include guidelines that assist when backing a trailer into place and a Trailer-Angle Indicator to show the relationship between the truck and compatible trailer. Rear Trailer View requires the customer-installed available GM auxiliary accessory camera. New Cargo Bed Zoom View and Bed Hitch Guidance are now available, which can be helpful for aligning and hooking up a gooseneck/fifth-wheel trailer.
When driving forward on the 2020 GMC Sierra, Rear Side View provides a split view of the left and right sides of the truck and compatible trailer that is automatically biased based on the trailer’s angle. In the 2021 GMC Sierra, drivers will have access to this view while driving in reverse, making it easier to see surrounding vehicles and objects while positioning a trailer. Select trailering features require a conventional-hitched box or camping trailer and additional setup may be required.
The available 3.0L Duramax Turbo-Diesel, which provides an ideal balance of performance and efficiency with 460 lb-ft of torque and best-in-class horsepower while offering up to an EPA-estimated 30 mpg on the highway, is a popular choice for GMC Sierra customers. For 2021, the MSRP of the popular engine will be reduced by $1,500, placing it at $995 MSRP above the Sierra 1500’s 5.3L V-8 with Dynamic Fuel Management. Similar to the Sierra 1500, the Sierra Heavy Duty AT4 will now have available 18-inch Mud Terrain tires and an available off-road high clearance step accessory. ■
