At the heart of the 2021 GMC Sierra 2500 HD AT4 lies the legendary 6.6L V8 Turbo-Diesel Duramax engine, producing 445 horsepower at 2,800 rpm and a staggering 910 lb-ft of torque at 1,600 rpm. Paired with the Allison® 10-speed automatic transmission, this powertrain delivers seamless power delivery, whether you’re towing a trailer or climbing steep grades. The diesel engine’s low-end torque ensures effortless acceleration, with a 0-60 mph time of around 6.5 seconds despite the truck’s 7,650-lb curb weight.

The 4WD system, with a two-speed Autotrac transfer case, offers modes for 2WD, 4WD High, and 4WD Low, adapting to any terrain. The AT4’s off-road package includes skid plates, all-terrain tires, and a traction control system optimized for mud, snow, or sand. With a payload capacity of 3,715 lbs and a towing capacity of up to 18,500 lbs, this Sierra is ready for heavy-duty tasks, from hauling construction materials to towing a fifth-wheel camper to Baxter State Park.

Fuel efficiency is impressive for a heavy-duty diesel, with real-world estimates of 15-18 mpg on the highway, thanks to the efficient Allison transmission and advanced fuel management. The 36-gallon fuel tank extends your range, perfect for long hauls across Maine or beyond. The integrated exhaust brake enhances control when towing downhill, reducing wear on the brakes.

Safety and Technology: Confidence in Every Scenario

The 2021 GMC Sierra 2500 HD AT4 is equipped with advanced safety features, earning high marks from the NHTSA. Standard equipment includes six airbags, a reinforced steel frame, and StabiliTrak with Traction Control for stability on slippery surfaces. The GMC Pro Safety suite adds Forward Collision Alert, Automatic Emergency Braking, Lane Departure Warning, and Front and Rear Park Assist, enhancing driver confidence in busy lots or on highways.

The HD Surround Vision camera system provides a 360-degree view, with up to 15 camera angles, including a bed view for monitoring cargo. The Rear Cross Traffic Alert and Lane Change Alert with Side Blind Zone Alert make merging and towing safer. The Trailering Package includes a trailer tire pressure monitoring system and a transparent trailer view, ideal for aligning hitches or monitoring loads.

For families, the LATCH system ensures secure child seat installation, and the Teen Driver mode allows customizable speed and audio limits. Every pre-owned Sierra at Emerson Chevrolet undergoes a 172-point inspection, and this AT4 comes with a comprehensive service history and optional extended warranties for added protection.

The GMC Sierra Legacy

Introduced as a heavy-duty model in 1999, the Sierra has evolved into a segment leader, outpacing rivals like the Ford F-250 Super Duty and Ram 2500 in towing capacity and interior refinement. The 2021 AT4 trim adds off-road flair, making it a standout for buyers seeking both workhorse strength and adventure-ready performance.

Lifestyle Fit: The Sierra 2500 HD AT4 for Every Need

Imagine loading the Sierra’s bed with snowmobiles for a trip to Sunday River, the MultiPro Tailgate doubling as a step for easy access. Or towing a horse trailer to a farm in Brunswick, with the family enjoying the spacious cabin and Bose audio. Contractors will appreciate the payload capacity for heavy equipment, while the luxurious interior impresses clients. The diesel engine’s efficiency appeals to eco-conscious buyers, reducing fuel costs over time.

Ownership and Maintenance

The 6.6L Duramax diesel is built for longevity, with recommended oil changes every 7,500 miles using synthetic oil. DEF (Diesel Exhaust Fluid) refills are needed every 5,000 miles for emissions compliance. Tire rotations every 6,000 miles ensure even wear on the all-terrain tires. Emerson Chevrolet’s service team is trained on GM diesels, and our parts department stocks filters, belts, and more to keep your Sierra running smoothly.

Competitive Edge

Versus the 2021 Ford F-250 Super Duty Tremor: The Sierra’s Duramax engine offers more torque (910 lb-ft vs. 1,050 lb-ft for the Ford’s 6.7L, but with better fuel economy), and the MultiPro Tailgate is unmatched.

Versus the 2021 Ram 2500 Power Wagon: The Sierra’s interior is more refined, and its towing capacity exceeds the Ram’s 10,620 lbs.

Versus the 2021 Chevrolet Silverado 2500 HD ZR2: The Sierra AT4 offers a more premium cabin and exclusive features like the MultiPro Tailgate.

Economic Benefits

The Sierra 2500 HD holds strong resale value, with KBB noting above-average retention for 2021 models. Diesel efficiency lowers long-term fuel costs, and insurance rates are competitive for a heavy-duty truck. Over five years, ownership costs are favorable due to GMC’s reliable engineering.
