Ford has revealed details of its new 7,3-litre V8 petrol engine, which will do duty in the F-Series range in the United States.
The new naturally aspirated unit will power the Super Duty pick-up, cranking out what the Blue Oval brand claims is a “best-in-class” V8 petrol output of 320 kW at 5 500 r/min and peak torque of 645 N.m at 4 000 r/min.
The V8 features an overhead valve architecture that Ford claims generates power “low in the rev range to help get heavier loads moving sooner and with greater confidence”. It also boasts 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.
Set to be available first in Super Duty F-250 and F-350 variants, the new engine joins the existing 6,2-litre V8 in the Super Duty line-up, along with a 6,7-litre diesel V8.
A slightly detuned version of the new 7,3-litre mill will be standard on F-450 chassis cab, F-550, 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 new engine.
For F-250 through F-600 models, the new powerplant will be paired with a ten-speed heavy-duty TorqShift automatic transmission. All other commercial models retain the heavy-duty six-speed automatic transmission.
“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 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,” Beltramo added.
