2026 Ford Super Duty Diesel Engine Specs

New Super Duty Inventory Used Super Duty Inventory Super Duty Research Hub

The foundation of the Ford Super Duty’s reputation in Abilene is the Power Stroke® diesel engine family. For the 2026 model year, Ford continues to refine the 6.7L V8 platform. This engine is designed for maximum thermal efficiency and sustained torque delivery under heavy loads. Whether you are hauling equipment to a job site or pulling a horse trailer across West Texas, these specifications define the capability of the 2026 lineup.

6.7L Power Stroke® V8 Turbo Diesel Options

The 2026 Super Duty features two distinct versions of the 6.7L Power Stroke engine. The standard output version provides a balanced approach to fuel economy and power. The High Output (HO) variant utilizes a unique turbocharger design and upgraded exhaust manifolds to push performance limits.

The HO diesel engine is easily identified by its red "6.7L Power Stroke" lettering on the badging. It utilizes a water-cooled variable geometry turbocharger. This system is engineered to reduce lag and provide immediate throttle response even when the truck is at its maximum gross combined weight rating.

Cooling and Durability Engineering

Towing in the Texas heat requires advanced thermal management. The 2026 Ford Super Duty diesel engines utilize a high-capacity cooling system with a massive radiator and a high-airflow fan. The engine block is constructed from compacted graphite iron. This material is stronger and lighter than traditional cast iron. It provides the structural integrity needed to handle the 1,200 lb-ft of torque generated by the High Output version without adding unnecessary weight to the front axle.

Transmission Integration

	Both diesel engines are paired exclusively with the 10-speed TorqShift® automatic transmission. This gearbox features selectable drive modes including Tow/Haul, Eco, Slippery, and Deep Sand/Snow. The gear ratios are optimized to ensure that the engine stays within its peak torque curve of 1,600 to 2,000 rpm during heavy acceleration.
