Just when you thought GMC had done it all with its pickups, it pulled a fast one with the new 2021 model of the GMC Sierra. The features it plans to offer consumers for the new year will probably draw lots of attention.

Motor Trend goes over the new upgrades as well as other changes GMC plans for the new Sierra model. It looks as if General Motors is putting in place what many truck buyers have only put on their wish lists. 

New technology coming to the 2021 GMC Sierra

The 2021 Sierra will come with Trailer-length and Trailer-Angle indicators. It’s a camera system working together to let the driver know where the trailer is behind you. 

The length version will alert you to vehicles that might be too close behind or near the trailer, so you won’t cause an accident by attempting to turn. The angle feature will help you know if the trailer is moving in the direction you want it to when making turns. 

You will also get the Jack-Knife Alert that will warn you if the trailer isn’t lined up where it needs to be, which could cause a jack-knifing accident. This will enable you to correct the issue before it becomes a big problem. 

The Rear Side-View Enhancement will let you know if the trailer wheels are about to run something over, so you can take appropriate action if needed. The Bed-Zoom View aids in backing up to attach to 5th-wheel trailers or to gooseneck hitches. 

Other changes coming to the truck

There are a few other changes coming to the GMC Sierra in 2021. One of them is the price change on the 3.0-liter Duramax turbodiesel Inline-six engine. 

The price is set to drop $1,500, which will make it almost $1,000 above the 5.3-liter V8 motor with the Direct fuel management system. 

GMC also plans to extend the Multi-Pro Swiss Army tailgate option to the SLE as well as the Elevation trim levels. Also, it plans to offer some new paint colors to brighten up the line. 

The AT4 trim will get new 20-inch wheels. These will be Goodyear Wrangler Territory brand tires that will complement the new high-clearance assist step for off-roading.

Towing for Beginners: How to Determine Your Vehicle’s Towing Capacity

The Sierra was a finalist in the 2020 Truck of the Year by Motor Trend. GMC dropped a 3.0-liter turbodiesel Inline-six engine and a 2.7-liter Inline-four motor into some of the trucks. This impressed reviewers because it showed that big V8 motors weren’t always necessary in light-duty trucks. 

Fuel economy ranges from an EPA-estimated 19 to 30 highway miles per gallon, depending on which engine you have and whether it has a rear-wheel or all-wheel drive train. The larger V8 motors tend to get an estimated 19-20 highway mileage. 

The interior offers a 7-inch display screen with Apple CarPlay and Android Auto capability. You can also get a WiFi hotspot, a six-speaker stereo, and Bluetooth connectivity. The higher trim levels get you USB ports, towing cameras, an 8-inch touchscreen, upgraded stereo, and a wireless charging device. 

Two other engine options you could get with the Sierra are a 4.3-liter V6 and a 6.2-liter V8 motor, which produces 420 hp. It’s 12,100 lbs of maximum towing capacity makes the Sierra a well-rounded truck. 

The GMC Sierra has already proven to be a force to reckon with. The new 2021 model promises that it will take it to a whole new level with the new trailer technology and the other changes GMC has planned.
