While some have declared the internal combustion engine is on its last legs, automakers have been proving there’s still plenty of life. The latest example is Ford’s all-new 7.3-liter V-8 for the Super Duty line. It bests other gasoline engines in its class by whipping out a potent 430 horsepower at 5,500 rpm and 475 lb.-ft. of torque at 4,000 rpm.
According to Ford, the overhead valve configuration helps with generating solid power at lower engine revs. For trucks, especially the Class 2 to Class 7 range this engine will be serving, that kind of low-end grunt is absolutely necessary.
As you can also imagine, the 7.3-liter V-8 was tested for durability in all kinds of crazy environments. Commercial operations need reliable vehicles in the scorching desert as well as the front tundra. Among the key designs created for durability is a forged steel crankshaft, variable-displacement oil pump, and piston cooling jets.
We’ll see this engine first in the Ford Super Duty F-250 and F-350 models. Instead of pushing out the current 6.2-liter V-8, the 7.3-liter engine will be an additional option. Ford won’t release any towing or payload ratings for the trucks when equipped with the new engine, saying those figures will be available later in 2019.
