Caught! 2017 Ford F-350 Single-Cab Dualie

Scorpion Diesel Will Carryover, Gas Engines Unknown

May 27, 2015
Ford is getting into aluminum in a major way. Already showing an all-in commitment with its best-selling F-150, the Blue Oval’s Super Duty line is scheduled to follow its little brother’s path for the 2017 model year. The weight savings on the Super Duty are expected to surpass even the F-150’s impressive 700-pound savings. As with the F-150, the weight savings on the body will likely translate into higher towing and payload capacities, even more critical with HD buyers than with 1/2-ton customers.
The refined, yet powerful, 6.7L “Scorpion” turbodiesel V-8 is expected to carryover largely unchanged from its 2015 specs of 440 hp and 860 lb-ft of torque. However, a modest increase in horsepower or torque might be in store. The 2017 Super Duty may also debut a new 10-speed automatic transmission, a version of which was recently announced for the 2017 F-150 Raptor.
The only major piece of the 2017 Super Duty puzzle that’s still unknown is what the gas engine option will be. It’s widely believed that the powerful, but thirsty, 6.2L SOHC V-8 will be put out to pasture with the next-gen Super Duty, leaving Ford’s 5.0L DOHC V-8 or even the possibility of a version of the 3.5L EcoBoost V-6. Strictly from the standpoint of output, both engines could stand in for the current 6.2L V-8 in the Super Duty, which produces 385 hp and 405 lb-ft of torque. The 5.0L V-8 in the 2015 F-150 also produces 385 hp, with slightly less torque at 387 lb-ft. The 3.5L EcoBoost has slightly less horsepower but actually makes 15 lb-ft more torque than the 6.2L in the Super Duty. The non-venturi exhaust tip on this development mule suggest it is equipped with a gasoline engine.
Thermal management is a major issue on these trucks, especially under load, so our guess is a version of the 5.0L will be under the hood, but Ford could surprise us all with a V-6 for the Super Duty. The majority of Super Duty trucks are sold with the diesel, a trend expected to continue with the new Super Duty models, but many fleets like a gas option for its lower initial cost and easier maintenance. The announcement of the 2016 F-150 getting the 5.0L V-8 for its gaseous fuel option indicates it may also be offered in the new Super Duty.
