Earlier this year, Ford introduced a new engine option for its updated 2020 Super Duty truck family. During the 2019 Chicago Auto Show, Blue Oval wasn’t ready to reveal the issue number for the unit, but now we finally have it. And they are good.
The 7.3-liter V8 petrol motor produces up to 430 horsepower (320 kilowatts) at 5,500 rpm and a “best in class” torque of 475 pound-feet (644 Newton-meters) available at 4,000 rpm. Featuring the proven upper valve architecture, the new V8 also incorporates a variable displacement oil pump, extra-large main bearings, forged steel crankshaft and piston cooling jets for better temperature management under heavy loads.

In fact, the new engine will be available in two power output versions. The less powerful one has 350 hp (261 kW) and 468 lb-ft (635 Nm) of torque and will come standard on chassis cabs of the new F-450, F-550, F-600, F-650, and F-750 Medium trucks. Duty, as well as the F-53 and F-59 and upgraded E-Series stripped chassis models. The 450-hp variant, in turn, will be available in the F-250 and F-350 trucks, joining the 6.2-liter V8 and 6.7-liter V8 diesel already offered.
“7.3 liters are designed for maximum endurance in the harshest environments considering our customers live and work in these conditions every day,” commented Joel Beltramo, Ford manager for V8 gas engines. “These engines have the largest displacement in their class and are designed to deliver benefits in key areas such as power, durability, ease of maintenance and total operating costs.”
The new 7.3-liter engine option will be mated to Ford’s new 10-speed automatic gearbox on all models except the F-650 and F-750, which will continue with the 6-speed heavy-duty car.
Another novelty for the 2020 model year is the addition of the Power Takeoff feature as standard on models equipped with the 6.7 liter Power Stroke diesel engine. Combined with a 10-speed automatic, the PTO provides up to 300 ft-lb (407 Nm) of stationary torque for commercial vehicle bodies where motor power is required directly to hydraulic components or bodies for snowplows, generators, and hydraulic units. The PTO feature will be optional for trucks powered by the new 7.3 liter V8 gas motor.
