New Ford 7.3-litre V-8 gives Super Duty pickup best-in-class power and torque

Aug 1, 2019   Vehicle Launch

Ford F-Series, America’s best-selling truck for 42 years, is once again raising the bar for capability with its all-new 7.3-litre V-8 petrol engine.

The 7.3-litre engine in Super Duty pickup cranks out best-in-class petrol V-8 output of 430 horsepower at 5,500 rpm and best-in-class torque of 475 ft.-lb. at 4,000 rpm.

No other competitor provides such a powerful and advanced petrol engine in such a broad range of offerings – from Class 2 Super Duty pickups through Class 7 commercial trucks.

“The 7.3-litre 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 petrol 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.”

Based on decades of commercial engine experience, the 7.3-litre V-8 delivers class-leading performance in a compact package. The 7.3-litre V-8 features an overhead valve architecture that generates power low in the rev range to help get heavier loads moving sooner and with greater confidence. It also features a variable-displacement oil pump, extra-large main bearings, forged steel crankshaft for durability, and piston cooling jets to help manage temperatures under heavy load.

The all-new 7.3-litre will be available first in Super Duty F-250 and F-350 pickup models. It joins the 6.2-litre V-8 petrol engine in Super Duty’s lineup, along with the upgraded third-generation 6.7-litre Power Stroke® diesel V-8. Additional power and capability numbers, including Super Duty towing and payload ratings as well as power numbers for the upgraded 6.7-litre Power Stroke diesel will be announced later this year.

A dyno-certified version of the 7.3-litre V-8 producing 350 horsepower at 3,900 rpm and 468 lb.-ft. of torque at 3,900 rpm will be standard on F-450 chassis cab, F-550, the new F-600, F-650 and F-750 Medium Duty trucks, and F-53 and F-59 stripped chassis models. The upgraded E-Series will also feature the 7.3-litre V-8. An optional calibration intended to help customers reduce their fuel consumption will also be offered; more information will be made available at a later date.

The 7.3-litre 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.
