2024 GMC Sierra 2500HD Colors: Exterior Colors & Interior Colors – GMC Sierra HD trucks can do a lot of work, but they don’t just stop there. The big, powerful workhorses are also very well-maintained, with a chromed exterior and leather seats on the interior. Sierra 2500HD & 3500HD is the big brother of the Sierra 1500. GMC’s pickups are more luxurious and finished than Chevy Silverado HD models. The base engine is a 401-hp, 6.6-liter V-8 engine with a 10-speed automatic. A 445-hp Duramax Turbodiesel V-8 and 10-speed transmission are available to achieve the 22,500-pound maximum conventional trailering capacity of the Sierra HD.
The Sierra HD is more intelligent than ever with its additional trailer assistance features, such as Transparent Trailer View and Trailer Side Blind Zone Alert. It also offers adaptive cruise control when towing. The heavy-duty Sierra may not have the same polish or maximum towing as competitors like the Ram HD or Ford Super Duty but it is a good choice for anyone with an empty truck-sized hole.
GMC’s heaviest pickup receives a subtle visual refresh, among other changes. These include a new trim and a revised engine that provides more towing capability. Sierra HDs receive a new front fascia, which includes LED taillights that have sequential turn signals and newly available headlights. The power and torque of the 6.6-liter Duramax Turbocharged Diesel V-8 have been increased respectively to 470 horsepower, and 975 pounds-feet. This increased torque has improved the Sierra 3500HD’s towing capability, which is now rated at 22,500 pounds. Allison’s 10-speed auto replaces the six-speed manual transmission of the 401-hp, 6.6-liter gas engine. The diesel engine was the only one with this feature.
Denali Ultimate is a new trim that joins the 2500HD, and 3500HD, and adds even more luxury to this popular trim. Denali Ultimate adds leather to the door panels, steering wheels, A- and Bpillar handles, as well as all other parts of the Sierra 1500. These 16-way heated and cooled message front seats also feature intricate leather stitching that features a topographic image of Mount Denali, Alaska. The new technology for trailering is also included in these revisions, such as adaptive cruise control while towing, Gross Combination Weight (GCW), and GM’s Transparent trailer view, which can now be used with gooseneck or fifth-wheel trailering. For 2024, the standard driver-assistance tech of Sierra HD has been increased. The AT4X trim also includes an AEV edition that features steel bumpers and AEV 18″ wheels. It’s also equipped with stronger skidplates.
Start with the Sierra 2500HD crew cab, and then choose the bed standard. The rugged AT4 models and the chrome-laden Denalis are not worth it despite their improved appearance. We recommend the SLT trim and adding the diesel V-8 and four-wheel drive. The standard on the SLT is GMC’s MultiPro tailgate. It also includes a heated wheel, heated seats in front, power-adjustable front seats, and a remote starter. The SLT trim unlocks a wider range of options than its lower-level SLE counterpart.
The SLT Convenience Package includes heated rear seats and power sliding rear windows, as well as front bucket seats that have ventilated cushions. These Driver Alert Packages are worth considering because they help make this behemoth more manageable thanks to features like blind-spot detection, lane departure warning, and front-and-rear parking sensors.
The Sierra 2500HD & 3500HD are equipped with a large dashboard, which is adorned by a user-friendly set of switches. The front bench can be removed from most models to make room for a center console and bucket seats. Interior options for the Sierra include a heated wheel, heated and cooled seats in front, as well as wireless charging. The cabin is a disappointment in terms of panel fit and quality. There are plenty of surfaces with a soft feel, and the majority of models have durable plastic. However, even though there is a lot of this, Denali, which is at the top of its line, falls far short of what it claims to be.
Denali Ultimate is the most luxurious trim, featuring leather interior trim, Paldao trim, soft microsuede, and more. Ram’s upscale alternatives are a better choice than GMC, primarily because they have a more luxurious look. Sierra HD is a good option for buyers of pickup trucks who value practicality and versatility. The GMC crew cab is awash with cubby-style storage. The GMC’s long and standard cargo boxes feature built-in steps at both ends of the beds, and its rear bumper features them in each corner. Customizations include LED lighting, tie-downs that can be moved, and 120-volt outlets. Its innovative, multi-functioning tailgate is the highlight of this heavy-duty Sierra. This feature has six positions and includes a bench as well as a working surface. This is a tailgater’s dream.
Sierra HDs come with a touchscreen system that supports Apple CarPlay or Android Auto. Base models may have fewer options but can be equipped with a 120-volt outlet or a mobile WiFi hotspot. The majority of trim levels come with an 8-inch display and extra charging ports. The systems all come with a set of rotary buttons and physical controls that are easy to reach. Upgrades include a larger touchscreen with SiriusXM Satellite Radio, Bose Audio System, built-in Navigation, as well as a Bose Audio system. The 13.4-inch touchscreen infotainment system offers a more integrated experience, with Google Built-in and split-screen navigation. It is also compatible with wireless Apple CarPlay or Android Auto. The display comes standard in Denali and Denali Ultimate trims. GMC offers an app for smartphones that allows remote control of trailer functions. The infotainment feature of the truck allows for different profiles on trailers to be stored to track maintenance.
Standard on the Sierra HD is a 6.6-liter gas-powered V-8 with 464 pound-feet of torque and 401 horsepower. The Sierra HD is available with either rear- or 4-wheel drive and paired with a 10-speed transmission. Duramax diesel’s 6.6-liter V-8, available as an option, produces 470 horsepower and 975 pounds-feet. It is driven by an Allison 10-speed auto. For 3500 HD, you can specify a dual or single rear-wheel drive (also known as “dually”). We’ve driven only the earlier diesel versions, but we have tested the gasoline-burning engine on the Chevy Silverado 2500HD. There’s no doubt that the Duramax powertrain is the highlight of the Sierra heavy-duty, making it a must-have for anyone who tows substantial loads.
It is surprising how refined the engine and transmission are. The 2500HD Denali that we tested was able to accelerate impressively quickly thanks to both of them. GMC’s massive GMC has a comfortable ride for its size. Sierra feels agiler than heavy-duty rivals, despite its vague steering at highway speeds. AT4X and AT4 models, which are trail-ready versions of the chrome-laden rigs that you’re used to seeing on roads today, have an off-road rear differential and enhanced suspension for rough terrain.
Sierra 3500HD is capable of towing up to 36,000 pounds. These massive capacities are only possible with a diesel engine, regular cabin, rear-wheel-drive, dual-rear-wheel axle, and gooseneck hitch. With a fifth-wheel hitch, the same truck’s towing capacity drops from 32,000 pounds to just 32,000. Sierra 2500HD only comes with one rear-wheel-drive axle and the heaviest version can tow 22,500 lbs.
We can’t compare the real-world mpg of the Sierra HD with its competitors because the EPA does not test such heavy vehicles. The Sierra 2500HD Denali diesel model we tested achieved 17 mpg on the highway. Comparatively, both the Ram 2500 Tradesmen and Silverado LTZ regular cab diesels that we have tested achieved 19 mpg. GMC owners who choose the standard V-8 gas engine should be prepared to get even less fuel efficient than those with diesel.
