Ford has released some of the vital performance numbers for its all-new 7.3L gas engine that it introduced earlier this year as the latest powertrain option for its 2020 Super Duty lineup. 

The big-block engine cranks out best-in-class gas V-8 output of 430 hp at 5,500 rpm and best-in-class torque of 475 lb.ft. at 4,000 rpm in Super Duty pickups.

A dyno-certified version of the 7.3L V-8, producing 350 hp at 3,900 rpm and 468 lb.-ft. of torque at 3,900 rpm, is standard on the F-450 chassis cab; the F-550; the new F-600, F-650, and F-750 Medium Duty trucks; and F-53 and F-59 stripped chassis models. 

Also new on the 2020 Super Duty Chassis Cab, a power take-off (PTO) provision will be included as standard with the third-generation 6.7L Power Stroke turbo diesel engine for auxiliary power needs on commercial vehicles.

“Adding PTO as standard on Super Duty Chassis cab vehicles with the diesel engine protects both the customer and dealer as it is often an overlooked option,” said Kevin Koester, Ford Commercial Truck Brand Manager. “It’s a critical component to deliver power on the move and operate equipment while the engine is running.” 

The New 7.3L Engine 

The 7.3L V-8 features an overhead valve architecture that helps get heavier loads moving sooner due to power low in rev range, according to Ford. It also features a variable-displacement oil pump, extra-large main bearings, forged steel crankshaft, and piston cooling jets to help manage temperatures under heavy load. 

It will be available first in Super Duty F-250 and F-350 pickup models. It joins the 6.2L V-8 gas engine in Super Duty’s lineup and the upgraded third-generation 6.7L Power Stroke diesel V-8. 

The 7.3L engine is paired with the all-new Ford-designed and Ford-built 10-speed heavy-duty TorqShift automatic transmission on all models except F-650 and F-750, which retain the heavy-duty 6-speed.

“The 7.3L is designed for maximum durability in the harshest environments given that our customers live and work in these conditions every day,” said Joel Beltramo, Ford manager for gas V-8 engines. “This engine has the largest displacement in its class and is designed to provide benefits in key areas like power, durability, ease of maintenance, and total operating costs.”

Updated PTO Offerings

Fleets that depend on work trucks often need to power additional equipment, either stationary or while moving.

Ford’s Live-Drive PTO allows commercial customers to power industrial equipment and accessories, including generators, snowplows, and hydraulic units while the truck is in motion. 

Combined, the 6.7L Power Stroke and all-new TorqShift 10-speed heavy-duty automatic transmission with the PTO provision delivers best-in-class stationary torque of up to 300 lb.-ft. for commercial vehicle bodies that require direct-to-component or hydraulic body motor power.

“For a lot of our commercial and heavy-duty retail customers, PTO power is the only way they can get a job done,” Koester said. “More standard PTO torque gives upfitters and customers the knowledge and comfort that they’ve got a chassis capable of the heaviest workloads.” 

A PTO allows fleets to mount accessory equipment to the transmission for auxiliary power from the engine to increase application functionality when direct or hydraulic power is required, such as generators, cranes, wreckers, pumper trucks, and boom lifts. 

The PTO provision will remain optional on 2020 Super Duty Pickup models and 7.3L gas V-8 Chassis Cab models.
