In the heavy-duty trucks world, the Ford Super Duty continues its wave of momentum. When you look at its pure muscle and high-tech cabin updates side by side with a competitor like the 2026 GMC Sierra HD, the choice is clear. Or is it? Let's find out by comparing Ford and GMC approaches to HD truck capability.
Key Takeaways:
- Ford focused its changes on making life easier for owners, while updates to the Sierra are mostly minor styling tweaks.
- The Super Duty lineup gives you more engines to choose from and holds some of the highest torque numbers in the business.
- The Sierra HD is no slouch, with a 36,000-pound max tow rating, but the Super Duty manages to push the ceiling even higher.
What Did Ford Change for the 2026 Ford Super Duty?
For 2026, Ford made a calculated move to take the stress out of massive hauling jobs. It migrated their top-tier trailering technology into the Lariat Premium package, which means getting features like Pro Trailer Hitch Assist and Backup Assist is now much more straightforward.
These tools are game-changers when you're trying to manage the truck's massive 40,000-pound maximum towing capacity. Beyond the tech, Ford also brought back the SuperCab paired with the 6.5-foot bed and, for the first time, is allowing buyers to combine the high-output diesel engine with the off-road Tremor package.
The 2026 Sierra HD, on the other hand, is mostly staying the course. GMC didn't feel the need to reinvent the wheel this year, opting instead for some small cosmetic shifts. You'll see a few new paint colors that swap out older shades for slightly different tones, and they've expanded the availability of the versatile MultiPro tailgate across more of the trim levels.
What is the Best Engine to Select in a 2026 Ford Super Duty?
If your priority is finding the absolute most powerful engine on the market, the 6.7-liter Power Stroke diesel is the king of the mountain. In its standard form, it delivers 1,050 lb-ft of torque, and the High-Output version cranks things up to 500 horsepower and a class-leading 1,200 lb-ft. If you aren't a diesel fan, Ford still offers two strong gas options: the 405-hp 6.8-liter V8 and the legendary 500-hp 7.3-liter "Godzilla" V8. Every engine in the Ford camp mates with a 10-speed automatic and your choice of rear- or all-wheel drive.
GMC keeps its lineup simple with two choices. You have the 6.6-liter gas V8 producing 401 horsepower and 464 lb-ft, or the 6.6-liter Duramax turbo-diesel that cranks out 470 horsepower and 975 lb-ft. Like the Ford, both GMC engines use a 10-speed automatic and offer RWD or 4WD, with the dual-rear-wheel axle available if you step up to the 3500 HD--impressive numbers, but not quite as powerful as the Super Duty's offerings.
The Super Duty boasts an 8,000-pound payload capacity and can tow a staggering 40,000 pounds when you're using a gooseneck setup. It also handles 35,000 pounds with a fifth wheel and 30,000 pounds with a standard hitch.
The Sierra 3500 HD is incredibly capable in its own right, but maxes out at 36,000 pounds. To hit that number, you need the diesel engine, a regular cab, RWD, the dual-rear-wheel axle, and a gooseneck hitch. If you're pulling with a fifth-wheel, it rates for 32,000 pounds. While it doesn't offer the dually setup in every configuration, it can still pull up to 22,500 pounds in its more standard forms, which is firmly in heavy-duty territory.
