Ford has unveiled its all-new 7.3-litre V8 gasoline engine. The new engine delivers 430 horsepower at 5,500 rpm and 475lb.-ft of torque. The engine is offered from Ford’s 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 gas V8 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.“
Ford says the engine was designed based on decades of commercial engine experience. The 7.3-litre V8 features an overhead valve architecture that generates power low in the rev range to help get heavier loads moving sooner with greater ability. 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 models. It joins the 6.2-litre V8 gas engine in Super Duty’s line-up, along with the upgraded third-generation 6.7-litre Power Stroke® diesel V8. 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 V8 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 V8. 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.
