Ford has released power ratings for the 7.3L V-8 gasoline engine that propels the 2020 F-600 chassis cab truck and provided technical details for the truck's 10-speed automatic transmission as well as its next-generation 6.7L PowerStroke V-8 diesel.
Ford will also begin offering standard power take-off (PTO) to commercial purchasers that opt for the diesel engine on Class 3 to Class 5 chassis cab trucks.
The new powertrain details came at a July 30 media briefing in Michigan.
Ford's 7.3L V-8 will be offered in two versions across the F-Series lineup above F-150 in the pickups, chassis cab trucks, and stripped chassis models. It will be paired with a new 10-speed transmission.
The first iteration of the engine is rated to provide up to 430 horsepower and 475 lb.-ft. of torque and will initially be offered in the F-250 and F-350 pickups alongside the carryover 6.2L V-8 gasoline engine and upgraded third-generation 6.7L diesel.
Commercial and fleet buyers of the chassis cab and stripped chassis models will get a dyno-certified engine that produces 350 hp and 468 lb.-ft. at 3,900 rpm. This version of the engine will be standard on the F-450 chassis cab, F-550, F-600, F-650, F-750, F-53, and F-59 models. The engine will also power an upgraded E-450 chassis cab van.
Ford is offering an optional engine calibration that helps the engine save fuel, as well as a transmission mode exclusively to commercial buyers that saves fuel when the truck is stopped at a red light.
The 7.3L engine should be a target for fleet managers who don't need the higher payload and towing capability of the 6.7L diesel, said Joel Beltromo, engineering manager for the engine.
"They need the strong towing, but don't need to step up to the bigger diesel engine," Beltromo said.
Ford's 6.7L diesel is entering its third generation with an array of improvements. The Scorpion nicknamed engine that debuted in 2011 arrives for 2020 with a more efficient turbocharger, variable displacement oil pump, updated fuel system with a maximum 2500 bar pressure rating, updated cylinder block, and larger oil cooler for hot-weather operation. Ford released the first Power Stroke diesel in 1994.
Other new parts include new forged steel pistons, bronze piston rods, and a gear-driven variable displacement pump. The new turbocharger has dual-axis vanes to improve flow.
All models pair the engine with a new 10-speed except for the F-650 and F-750, which retain a heavy-duty 6-speed automatic. Ford has been rolling out 10-speed TorqShift transmissions in the F-150, Explorer, and other vehicles. This one shares only 7% of its parts with the F-150 version. Many of the parts, including those that carry torque, are larger and more durable.
The oil and fluid interval remains at 15,000 miles for the vehicles.
Ford will offer a standard PTO with its 6.7L engine that provides 300 lb.-ft. of torque when the vehicle is stationary to support cranes and other auxiliary applications such as generators, wreckers, pumper trucks, boom lifts, snowplows, and dump trucks. The unit can also power equipment while the vehicle is in motion.
"For a lot of our commercial and heavy-duty retail customers PTO power is the only way they can get a job done," said Kevin Koester, Ford's commercial vehicle marketing manager. "With more PTO torque on hand every task is easier and even bigger projects are now within reach."
The PTO unit will remain optional on the Super Duty pickup models, as well as the 7.3L chassis cabs.
Editor's note: This story has been updated because we inadvertently mislabeled a photo of the 6.7L diesel engine. The story also misstated the date Ford introduced this engine. It was 2011.
