DETROIT — Ford Motor Co.'s newest offering on its Super Duty pickups -- a 7.3-litre V-8 gasoline engine -- will produce 430 hp and 475 pound-feet of torque.
Those figures rank best among V-8 gasoline engines in the category, although Ram's HD diesel engine keeps the overall power crown with 1,000 pound-feet of torque, an all-important measurement for large pickups that generally tow and haul heavy loads.
The new engine will debut on the F-250 and F-350 when the freshened vehicles go on sale this year.
"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," Joel Beltramo, Ford's manager for gasoline V-8 engines, said in a statement. "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."
The engine will be mated to a new 10-speed transmission that is based on the gearbox used by the F-150 but upgraded for the larger trucks. F-650 and F-750 will continue to use a six-speed transmission.
The 7.3-litre joins a 6.2-litre V-8 gasoline engine, as well as an updated 6.7-litre Power Stroke diesel V-8. The automaker did not disclose power figures for the diesel engine.
Ford last redesigned the Super Duty for the 2017 model year, when it shed as much as 350 pounds (159 kilograms) by switching to an aluminum body.
The midcycle freshening comes as Ford shifts 90 per cent of its capital allocation to producing pickups, vans and utilities. By 2020, roughly 75 per cent of its lineup will be updated or new.
Ford also said Thursday that its power takeoff feature, which allows customers to mount accessory equipment to the transmission for more power, will come standard with its 6.7-litre diesel engine. It will remain optional on both other engines.
