Under the Hood: Exploring the 2023 Ford Super Duty Engine Lineup

A redesigned heavy duty with updated powertrains.

Heavy-duty trucks used to be strictly commercial vehicles, but many consumers now buy them for towing boats, RVs, or other items. These trucks have become big business, and that’s a bonus for buyers because they’re continuously being updated with the latest features and technologies.

Ford has released a new Super Duty for 2023, which includes the F-250 and F-350, as well as the heavier-capacity F-450 that’s primarily for commercial use. All offer two new engines for a total of two with gasoline and two with diesel, all with a ten-speed automatic transmission, and we’ll take a deeper dive into them here.

The Gasoline Engines

  • Horsepower: 405 hp
  • Torque: 445 lb.-ft.
  • Displacement: 6.8L (415 cubic inches)
  • Compression ratio: 10.8:1
  • Valvetrain: Pushrod and rocker arms, two valves per cylinder
  • Recommended fuel: 87 octane
  • Fuel delivery: Sequential multi-port electronic
  • Intake manifold: Naturally aspirated, tuned intake

The first of the Super Duty’s new engines is its entry-level choice, a 6.8L V8 that makes 405 horsepower and 445 lb-ft of torque. It replaces last year’s entry engine, a 6.2L V8 that made 385 horsepower and 430 lb-ft of torque. The Super Duty’s styling enhancements include new grilles to improve cooling on all engines.

The XL base trim in the F-250 and F-350 is the only one that uses the 6.8L (but you can option it with the other three engines). The XL comes in 4×2 or 4×4, while all other trims come only in four-wheel drive.

7.3L V8

  • Horsepower: 430 hp
  • Torque: 485 lb.-ft.
  • Displacement: 7.3L (445 cubic inches)
  • Compression ratio: 10.5:1
  • Valvetrain: Pushrod and rocker arms, two valves per cylinder
  • Recommended fuel: 87 octane
  • Fuel delivery: Sequential multi-port electronic
  • Intake manifold: Naturally aspirated, tuned intake

The XLT, Lariat, King Ranch, and Platinum trims use a 7.3L V8 engine carried over from the 2022 models. It makes 430 horsepower and 485 lb-ft of torque. While we didn’t get to drive the 6.8L on a “first drive” of the F-250, we spent a few hours with the 7.3L engine. It’s powerful but very smooth, with linear acceleration, plenty of passing power, and equally smooth shifts from that ten-speed transmission.

Ford’s heavy-duty rivals each offer one gasoline engine. The Chevrolet Silverado and GMC Sierra use a 6.6L V8 making 401 horsepower and 464 lb-ft of torque; while the Ram Heavy Duty has a 6.4L V8 making 410 horsepower and 429 lb-ft of torque. Ford’s 6.8L falls between them for power ratings, but its 7.3L V8 tops both of them for horsepower and torque.

The Diesel Engines

The Super Duty’s carried-over turbodiesel engine is a 6.7L Power Stroke V8 that makes 475 horsepower and 1,050 lb-ft of torque. New for 2023 is a high-output version of it, making 500 horsepower and 1,200 lb-ft of torque. Heavy-duty trucks are all about torque, and the automakers often get into “torque wars” where one announces a new rating, and someone else scrambles to top it. Right now, that 1,050 lb-ft on Ford’s regular diesel takes the crown, with Ram’s 6.7L Cummins turbodiesel rated at 850 lb-ft, and GM’s 6.6L Duramax at 975 lb-ft. Ram further offers a high-output version as well, but its 1,075 lb-ft still doesn’t reach Ford’s 1,200 lb-ft. As well, Ram’s high-output is only available on its 3500, while Ford offers it in both the F-250 and F-350.

Super Duty Engines, Towing, and Payload Capabilities

Towing and payload capacity depend on a number of factors, including cab configuration, 4×2 vs 4×4, engine and driveline, type of trailer, and more. Ford advertises a maximum towing capacity of 40,000 lbs for the Super Duty, but that’s across the entire lineup – and when you read the fine print, it’s for the F-450 regular cab with high-output diesel.

For the F-250 crew cab, the most popular heavy-duty choice with consumers, conventional towing tops out at 18,200 lbs for gasoline, and 22,000 lbs for diesel. For fifth-wheel or gooseneck towing, it’s a maximum 19,300 lbs for gasoline, and that same 22,000 lbs for diesel.
