General Motors unwrapped the refreshed 2024 GMC Sierra HD last October, showing off some revised exterior styling, an overhauled cabin, powertrain changes, and several new trim levels. However, despite the extra gloss, the 2024 GMC Sierra HD still claims to cover all the heavy-duty pickup activities expected of it. Now, the 2024 GMC Sierra HD is showing off its heavy-duty DNA in a new video advertisement, as featured here.
Clocking in at 30 seconds, the video ad includes some nice glory shots of the refreshed 2024 GMC Sierra HD, as well as shots of it doing the traditional heavy-duty truck activities. Kicking it off, we see the pickup towing two enormous Sherp ATVs. As the ad boasts, the 2024 GMC Sierra HD offers a best-in-class maximum tow rating of 22,070 pounds, as available on Crew Cab Long Bed Pro, SLE, and SLT models with the optional NHT Max Trailering package, as well as Crew Cab Long Bed SRW models. In addition to towing those two massive ATVs, we also see the 2024 GMC Sierra HD pulling an enormous boat, and an equally gigantic RV. Check out previous GM Authority coverage for a more thorough breakdown of the 2024 GMC Sierra HD towing capacities.
Under the hood, the 2024 GMC Sierra HD offers a pair of engine options, including the naturally aspirated 6.6L V8 L8T gasoline engine, rated at 401 horsepower and 464 pound-feet of torque, as well as the optional 6.6L V8 L5P turbodiesel Duramax engine, which was uprated for the 2024 model-year refresh to produce a maximum of 470 horsepower and 975 pound-feet of torque. Both engines connect to the Allison-branded 10-speed automatic transmission, which replaces the GM six-speed automatic transmission equipped by gasoline-fueled Sierra HD models prior to the 2024 model-year refresh.
The ad also includes a brief look at the 2024 GMC Sierra HD Denali Ultimate, the new range-topper of the bunch featuring unique styling enhancements and a luxurious cabin space.
