The 2026 Ford Super Duty gives you four V8 engines to choose from – two gas, two diesel – and the right one depends entirely on what you tow, how often, and how far. Here is how all four break down, what the numbers actually mean for your workload, and how to decide between gas and diesel without overbuying or underbuying.

What engines does the 2026 Ford Super Duty offer?

The 2026 Super Duty offers four V8 engines: a standard 6.8L gas V8, an available 7.3L gas V8, an available 6.7L Power Stroke turbo diesel, and an available 6.7L High-Output Power Stroke turbo diesel. The High-Output diesel leads the class with 500 horsepower and 1,200 lb-ft of torque. All four pair with a 10-speed TorqShift automatic transmission.

A closer look at each engine

6.8L Gas V8

405 hp | 445 lb-ft | Standard on XL, XLT, Lariat

The standard engine and the value workhorse of the lineup. For a contractor hauling a trailer around the county, a farmer running equipment, or anyone whose towing stays under the heaviest ranges, the 6.8L does the job without diesel complexity. It is the most straightforward Super Duty engine to own and operate.

7.3L Gas V8 “Godzilla”

430 hp | 485 lb-ft | Standard on King Ranch, Platinum

Ford’s big-displacement gas V8, nicknamed Godzilla, is the answer for buyers who want serious gas torque without going to diesel. It pulls hard, runs on regular fuel, and stands up to heavy use – a favorite for those who tow often but want simpler maintenance than a diesel demands.

6.7L Power Stroke Diesel

475 hp | 1,050 lb-ft | Available on all trims

The standard-output Power Stroke is where serious towing begins. With 1,050 lb-ft of torque, it handles big fifth-wheels and goosenecks with ease and delivers the low-end pulling power and highway manners that make long hauls comfortable. For most heavy-tow buyers, this is the sweet spot.

6.7L High-Output Power Stroke Diesel

500 hp | 1,200 lb-ft | Available on all trims

The top engine and the one that unlocks the Super Duty’s maximum tow ratings. With 500 horsepower and a class-leading 1,200 lb-ft of torque, the High-Output diesel is built for the heaviest commercial trailers, the largest RVs, and anyone who needs every pound of the lineup’s 40,000-lb gooseneck capability.

Should I get the gas or diesel 2026 Super Duty?

Choose gas if you tow moderately, want simpler maintenance, and value a straightforward truck to own. Choose diesel if you tow heavy regularly, cover long distances, or need the highest capacity – the diesel’s torque and towing ceiling justify it for serious haulers. The break point is how heavy and how often you tow.

The honest answer is that most buyers do not need the biggest engine. If your trailer is under about 12,000 pounds and you tow a handful of times a month, a gas Super Duty will serve you well and keep things simple. But if you are pulling a 20,000-pound fifth-wheel across three states every month, the diesel’s torque, fuel range, and towing headroom pay off every mile. Match the engine to the real workload, not the spec sheet.

What transmission does the 2026 Super Duty use?

Every 2026 Super Duty engine pairs with a 10-speed TorqShift automatic transmission. It is built for heavy-duty work, with deep low gears for launching heavy loads and tall top gears for relaxed, fuel-efficient highway cruising.

The 10-speed spreads its ratios to keep whichever engine you choose in its strongest power band, whether you are pulling away from a stoplight with a loaded gooseneck or holding a steady 70 on the interstate. Live-drive grade control and tow/haul modes come into play for managing big trailers on grades.

Is the diesel worth it on a Super Duty?

The diesel is worth it if you tow heavy loads regularly or cover long distances, thanks to its high torque, towing ceiling, and fuel range. If you tow moderately, a gas engine is simpler and a better value. The deciding factor is how heavy and how often you tow.
