GM unwrapped the 2024 GMC Sierra HD last October, debuting a full model refresh that includes updated exterior styling, an overhauled cabin space, revisions to the trim level lineup, and powertrain updates, among other changes. Now, interested customers can spec the refreshed 2024 GMC Sierra HD to taste using the official online configurator.
As before, the 2024 GMC Sierra HD is once again offered in 2500 HD and 3500 HD configurations. The trim level lineup includes the base-level Pro, followed by SLE, SLT, AT4, the new-for-2024 AT4X, Denali, and finally, the new-for-2024 GMC Sierra HD Denali Ultimate. To note, the GMC Sierra HD AT4X will launch later in 2024, and as such, is currently unlisted from the official online configurator.
Pricing for the 2024 GMC Sierra HD starts at $46,295 for the 2500 HD Pro in a Regular Cab / Long Bed configuration with 2WD. The most expensive model on offer, specifically the 3500 HD Denali Ultimate in a Crew Cab / Long Bed DRW, starts at $100,695.
With regard to exterior styling, the refreshed 2024 GMC Sierra HD introduces revisions to the front bumper, the fascia, and the grille, presenting a bold, upright face with L-shaped lighting signatures lining the headlamps. The 2024 model year also introduces six new exterior colors, including Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic, and Downpour Metallic.
Inside, tech features and amenities vary a great deal between the various trim levels, with SLE and SLT trim levels offering a unique interior treatment, and AT4, Denali, and Denali Ultimate trim levels offering a premium interior design. Wi-Fi capability, Bluetooth, and Apple CarPlay / Android Auto support are all included as standard.
With regard to the power spec, the 2024 GMC Sierra HD features the naturally aspirated 6.6L V8 L8T gasoline engine as standard, rated at 401 horsepower and 464 pound-feet of torque. The 6.6L V8 L5P turbodiesel Duramax engine is optional, doling out an uprated 470 horsepower and 975 pound-feet of torque with the latest refresh.
