Trucks and SUVs are two segments where GMC shines. While some fans might gravitate toward the brand’s models for the latest tech amenities, safety tools, and convenience features, others gravitate toward the capability and powertrain potency these models boast. Here are some of the top contenders in the GMC lineup when it comes to the most powerful truck and SUV offerings.
The 2019 Sierra 2500HD and 3500HD deliver the most energy for those who prefer superior power and towing capacity. The Sierra HD comes with either the 6.0-liter Vortec V8 or the 6.6-liter Duramax V8 turbodiesel. The first outputs 360 horsepower and 380 lb-ft of torque, while the latter churns out an impressive 445 horsepower and 910 lb-ft of torque.
Per GMC, the 2500HD version yields a maximum towing capacity of 15,400 pounds, when properly equipped. The 3500HD version delivers a maximum towing capacity of 23,100 pounds to make even the heaviest job look easy.*
The 2019 GMC Yukon is the most powerful SUV in the brand’s lineup. Choose the 5.3-liter EcoTec3 V8 engine to take advantage of 355 horsepower and 383 lb-ft of torque. Upgrade to the Denali trim’s 6.2-liter EcoTec3 V8 engine, for even more force. This version churns out a gratifying 420 horsepower and 460 lb-ft of torque.
The 2019 GMC Acadia comes in second place behind the Yukon when it comes to power. An available 3.6-liter V6 engine provides 310 horsepower and 271 lb-ft of torque to suit moderate needs for performance.
*Requires 2WD Crew Cab equipped with available 6.6L Duramax Diesel and 5th-wheel or gooseneck hitch. Trailer weight ratings are calculated assuming properly equipped vehicle, plus driver and one passenger. The weight of other optional equipment, passengers and cargo will reduce the trailer weight your vehicle can tow. See dealer for details.
