2027 Ford Super Duty Engine Options: 7.3L Gas vs 6.7L Power Stroke Diesel
The 2027 Ford Super Duty offers two distinct V8 engines: a 420-hp 7.3L gas and a 500-hp 6.7L High-Output Power Stroke diesel. The gas engine is standard on F-250 and F-350 models, while the diesel is standard on the F-450 and available across all series. This page breaks down both engines, what separates them, and which truck fits your work, shop current inventory at Arrow Ford in Abilene.
2027 Super Duty Engine Overview
The 2027 Ford Super Duty is built around two purpose-engineered V8 powerplants. Both share an 8-cylinder layout and connect to the TorqShift 10-speed automatic transmission, but each has a fundamentally different character designed to serve a different type of operator.
| Engine | Output | Key Engineering Details |
|---|---|---|
| 7.3L 2V DEVCT NA PFI V8 Gas | 420 hp at 5,350 rpm and 445 lb-ft of torque at 4,250 rpm | Port fuel injection, cast-iron block with four-bolt and cross-bolted main bearings, and forged-steel crankshaft. |
| 6.7L High-Output Power Stroke V8 Turbo Diesel | 500 hp at 2,600 rpm and 1,200 lb-ft of torque at 1,600 rpm | Compacted graphite iron block, variable geometry turbocharger with water-jacketed design, high-pressure common-rail fuel delivery, and glow plugs. |
2027 Super Duty full specs and trims
Both engines run through the same basic transmission architecture. The gas engine pairs with the TorqShift-G 10-speed automatic, while the diesel pairs with the TorqShift 10-speed SelectShift automatic, which is reinforced to handle the diesel's significantly higher torque output.
How Each Engine Works
7.3L Gas: Port Fuel Injection and Mechanical Simplicity
Port fuel injection delivers fuel upstream of the intake valve rather than directly into the cylinder. This approach coats the intake path with fuel, which helps keep intake valves clean over time and tends to reduce the complexity of the fuel delivery system. The engine uses variable cam timing, DEVCT, to optimize power output across the rev range, shifting cam timing to favor low-end torque when pulling and high-end power when running unloaded.
The cast-iron block is a deliberate choice for commercial durability. Cast iron resists the thermal and mechanical stress that comes with sustained heavy hauling better than lighter materials. The forged-steel crankshaft handles the rotational forces from high-torque output without the flex that a cast crankshaft can develop under load.
Recommended fuel is standard 87-octane gasoline. The engine is not E85 compatible.
6.7L High-Output Power Stroke Diesel: Torque on Demand
The diesel engine uses high-pressure common-rail injection, which delivers fuel directly into each cylinder at very high pressure. This allows precise control of injection timing and quantity, which is why the engine can produce 1,200 lb-ft of torque at only 1,600 rpm. The variable geometry turbocharger adjusts its vane position based on engine load and speed, improving throttle response from a stop and sustaining boost pressure throughout the pull.
The water-jacketed turbocharger circulates coolant around the turbo housing, which reduces heat soak during extended hauling and allows the turbo to cool down faster after the engine is shut off.
Diesel engine exhaust braking is standard on the 6.7L. This system restricts exhaust flow to create back pressure, effectively using the engine to slow the truck while descending grades. It reduces heat buildup in the friction brakes, a meaningful advantage when descending long mountain grades with a loaded trailer.
Fuel is ultra-low sulfur diesel, and the engine supports B20 biodiesel blends.
Engine Availability Across the Trims
| Engine | Availability | Best Fit |
|---|---|---|
| 7.3L Gas Engine | Standard on all F-250 Super Duty and F-350 Super Duty models. Available on F-350 DRW configurations. Not offered on F-450. | Buyers who need a capable workhorse for moderate towing, payload hauling, and jobsite use without the fuel and maintenance considerations of a diesel. |
| 6.7L High-Output Power Stroke Diesel | Standard on all F-450 Super Duty configurations. Available as an upgrade on F-250 and F-350 models. | Buyers who need maximum gooseneck and fifth-wheel towing capability, including properly configured F-350 DRW and F-450 models. |
At Arrow Ford in Abilene, the F-250 XL Regular Cab and the F-350 XL Regular Cab both ship with the 7.3L gas as their base powertrain. Buyers selecting the diesel on an F-250 or F-350 should note that the diesel engine adds weight, which directly affects payload capacity relative to the gas engine in the same configuration.
On the F-350 DRW and F-450, the diesel unlocks gooseneck towing ratings that reach 40,000 lbs with the proper configuration and package. The gas engine on DRW models caps at lower gooseneck ratings.

The F-450 XL Crew Cab Long Bed DRW, available at Arrow Ford, is standard with the 6.7L diesel and targets buyers who need the highest towing and payload numbers the Super Duty lineup offers.
Real-World Benefit by Engine
Gas engine ownership
The 7.3L gas engine runs on widely available 87-octane fuel, which is straightforward to source across Abilene and across West Texas on long hauling runs. Routine maintenance intervals and service costs for a naturally aspirated gas engine are generally lower than for a turbocharged diesel. Contractors, ranchers, and fleet buyers who tow regularly in the 10,000-to-18,000-lb range and prioritize lower upfront cost and simpler maintenance will find the gas engine genuinely sufficient.
The 420-hp output is not a compromise. At 445 lb-ft of torque, this engine moves loaded goosenecks and bumper-pull trailers without strain. The TorqShift-G transmission pairs with it using five selectable drive modes: Normal, Eco, Slippery, Tow/Haul, and Off-Road or Trail. The Tow/Haul mode modifies shift points and enables engine braking through the transmission, which reduces reliance on friction brakes on downhill grades.
Diesel engine ownership
The 6.7L diesel is the engine to choose when towing is the primary mission and the loads are heavy. The 1,200 lb-ft of torque at 1,600 rpm means the engine is already pulling hard before most drivers have fully pressed the accelerator. On long hauls across the flat roads between Abilene and other parts of Texas, this low-rpm torque keeps a loaded trailer moving without repeated downshifts or elevated engine speed.
Diesel engine exhaust braking adds a measurable safety advantage on grades, reducing brake fade risk under sustained downhill loads. For ranchers moving livestock trailers or oilfield operators moving heavy equipment, this feature is a practical benefit on every haul, not just an edge-case feature.
The B20 compatibility of the diesel engine gives buyers in areas with biodiesel availability a fuel flexibility option.
How the Super Duty Engines Compare to the Segment
Ford rates the 6.7L High-Output Power Stroke diesel at 1,200 lb-ft of torque, which represents the highest diesel torque figure in the heavy-duty pickup segment for the 2027 model year. No other manufacturer currently matches this figure in a factory production heavy-duty pickup sold in the United States.
The gas engine at 420 hp and 445 lb-ft of torque is competitive within the naturally aspirated gas-powered heavy-duty segment. Unlike turbocharged gas engines offered by some competitors, the 7.3L relies on displacement and mechanical breathing rather than forced induction. This gives it a broad, smooth torque curve that is consistent under sustained load rather than peaking sharply and tapering off.
Both engines connect to a 10-speed automatic transmission. The wide ratio spread, with a deep first gear ratio of 4.696:1 on the gas side and 4.615:1 on the diesel side, allows the truck to launch heavy loads from a standstill without excessive clutch or gear wear. The three overdrive gears at the top of the range reduce engine speed at highway cruise, which supports fuel economy during unloaded or lightly loaded highway driving.
