Overview
The 2024 GMC Sierra HD pickup truck is a behemoth of power and luxury, capable of towing a staggering 22,500 pounds. This heavy-duty workhorse boasts a refined interior, advanced trailering technology, and impressive capabilities. Available in 2500HD and 3500HD models, the Sierra HD offers a higher level of luxury and finish than its Chevy Silverado HD counterpart.
Price
Priced from $47,395 to $94,895, the Sierra HD offers exceptional value for its capabilities. The recommended SLT trim level starts at $55,095 and features four-wheel drive, the diesel V-8, GMC’s versatile MultiPro tailgate, heated front seats, and power-adjustable front seats.
Engine and Transmission
The Sierra HD’s standard 6.6-liter V-8 gas engine produces 401 horsepower and 464 lb-ft of torque, paired with a 10-speed automatic. The optional Duramax diesel 6.6-liter V-8 cranks out 470 horsepower and 975 lb-ft of torque, paired with an Allison-certified 10-speed automatic. The diesel engine shines with refined performance, responsive transmission, and impressive acceleration.
Dimensions and Interior
The Sierra HD’s spacious crew cab offers extensive passenger room and practical storage solutions. The interior features user-friendly switchgear, a split-folding front bench, and optional amenities like heated-and-cooled front seats, wireless charging, and a head-up display. While materials quality is mediocre, the cabin prioritizes versatility. The new Denali Ultimate trim boasts luxurious leather-wrapped interior pieces, Paldao wood trim, and a soft microsuede headliner.
Performance
The Sierra HD’s trail-ready AT4 and AT4X models feature off-road suspension and a locking rear differential. The AT4X AEV adds stronger bumpers and exclusive aluminum AEV 18-inch wheels. With its impressive ground clearance and responsive steering, the Sierra HD feels more agile than its heavy-duty competitors.
Fuel Economy
The EPA doesn’t test heavy-duty pickups, but real-world testing reveals 17 mpg highway for the diesel Sierra 2500HD Denali. Compare this to 19 mpg for similar diesel-powered competitors. The standard gas-fed V-8 is expected to yield worse fuel economy.
In conclusion, the 2024 GMC Sierra HD is a powerhouse pickup truck that balances heavy-duty capabilities with refined features. With its impressive towing capacity, advanced trailering technology, and luxurious interior options, the Sierra HD is an excellent choice for those prioritizing practicality and versatility. While it may not match the polish and max towing of competitors, the Sierra HD remains a solid choice for heavy-duty truck enthusiasts.
