The Power Stroke V6 is the sixth engine choice for F-150 customers.

Ford has revealed more details of its diesel-powered F-150 as the first units begin heading to showrooms.

The 3.0-liter Power Stroke V6 is expected to get an impressive 30-mpg highway rating from the EPA, beating the 27-mpg highway rating achieved by the Ram 1500 diesel.

Ford also claims its diesel F-150 delivers best-in-class towing capacity of 11,400 pounds, with 250 horsepower and 440 pound-feet of torque beginning at 1,750 rpm.

Engineers picked a variable-geometry turbocharger to help improve responsiveness and reduce turbo lag, while a mechanical fan is claimed to be designed for improved performance at high altitudes or in extreme heat.

The downsized Power Stroke mill will be available for both 4x2 and 4x4 configurations. Deliveries are expected to begin this spring.
