KEY FEATURES

6.7L Power Stroke® V8 Turbo Diesel Engine

6.7L Power Stroke® V8 Turbo Diesel Engine—300 hp, 725 lb-ft. of Torque

The 6.7L Power Stroke® V8 Turbo Diesel engine has a standard power rating of 270 hp/700 lb.-ft. of torque. * You also have your choice of available 300 hp/725 lb.-ft. of torque and 330 hp/750 lb.-ft. of torque power ratings. * The 6.7L was tested to more than 500,000 miles (800,000 km) of simulated customer driving, which contributes to a B10 design life or more than three-quarters of a million kilometres. ** The unique inverse-flow design locates the turbocharger between the cylinder heads and the top of the block, with the exhaust manifold inboard and close to the turbo, for faster air displacement and greater power. The driver-activated engine exhaust braking restricts exhaust flow to create back pressure for seamless braking and reduced brake wear on downhill grades.

*Horsepower and torque ratings are independent attributes and may not be achieved simultaneously.

**B10 design life based on the 330 hp output version and Ford engine dynamometer testing.

Ford TorqueShift® Heavy-Duty 10-Speed Automatic Transmission—Double Overdrive

The Ford TorqueShift® HD 10-Speed Automatic Transmission leverages the proven performance of the Super Duty 10-Speed TorqueShift transmission. It has design efficiency and upfit ease with the same chassis footprint as the TorqueShift HD 6-Speed. Compared to the 6-speed, it offers smaller gear step ratios for more efficient, smooth operation without an RPM drop-off, as well as shorter first and reverse gear ratios for heavier applications on soft surfaces to get the vehicle moving even quicker.

Operator-Commanded Regeneration with Active Inhibit

Some operating conditions, such as long idling, don't generate enough engine heat for the diesel to automatically burn off soot in the diesel particulate filter. That's where available Operator-Commanded Regeneration with Active Inhibit comes in. When the warning light comes on, pushing the activation button raises the exhaust temperature to burn off the soot, after which the exhaust temperature reverts to normal. The Active Inhibit feature allows delay of regeneration until the vehicle is sitting in a safe location. Afterward, the driver can manually start the regeneration process. Recommended for commercial applications.
