Heavy duty buyers like their open-pore Paldao wood trim, too.
GMCSeptember was unofficially heavy-duty truck month. Ford launched the all-new Super Duty. Chevy unveiled the refreshed Silverado HD. Ram delivered a new off-road trim to slot below the Power Wagon.
Now, though, GMC is stretching the party into October — with the reveal of its new 2024 Sierra HD pickup.
There’s now a Sierra Denali HD Ultimate trim
The Sierra HD follows the Sierra 1500’s lead by adding a new and even cushier Denali Ultimate trim. On the outside, the Denali Ultimate trim adds a unique grille and badging in Vader Chrome with trim-specific machined aluminum wheels with gloss black accents.
The inside offers full-grain leather on the front and rear seats and door panels and open-pore Paldao wood. There’s also exclusive Denali Ultimate badging (lest anyone think you only bought the humdrum Denali).
GMC upgraded the Sierra HD engines
GMCThe 6.6-liter Duramax V8 diesel engine gets bumps up to 470 horsep0wer (+25 hp) and 975 lb-ft (+65 lb-ft) of torque. GMC also says the upgraded engine improves low-end torque by 25% over the outgoing model.
The 6.6-liter gas V8 keeps the same output, 401 hp and 464 lb-ft. But an upgrade to the 10-speed Allison transmission allows it to hold peak torque for longer periods.
A Sierra HD AT4X is coming…but not quite yet
GMCThe Sierra HD lineup will offer an upgraded AT4X off-roading trim too. But that will come out later in 2023 and won’t be available at launch. Chevy similarly teased but did not yet reveal details about its Silverado HD ZR2 counterpart.
The Sierra HD adds some new towing tech
GMCHD trucks are built to tow. And the Sierra HD will get some helpful towing tech. A Transparent Trailer View allows the driver to see through the trailer virtually. Blind zone alert and adaptive cruise control systems can now factor in the trailer. The Sierra HD also has a GCW alert that warns the driver when the trailer and truck exceed the Gross Combined Weight Rating.
The 2024 Sierra HD arrives very soon
GMCThe new Sierra HD will be a 2024 model-year vehicle. But GMC says the new truck will hit dealerships in early 2023.
