New Power Stroke diesel engine more durable, quiet

Ford has designed its new 6.7-liter Power Stroke V8 diesel engine for the Ford F-650 and F-750 lineup to travel an even greater distance than a round trip from the Earth to the moon.

This confidence in the 6.7-liter Power Stroke comes from engine dynamometer testing that shows a statistically proven B10 engine design life of at least a half-million miles. This is the estimate of miles in operation before 10 percent of engines are expected to require major service involving removal of cylinder heads or dropping the oil pan to reach internal components.

“F-650 and F-750 customers help keep America moving,” says John Ruppert, general manager, Ford commercial vehicle sales and marketing. “We’re here to make sure they can with our all-new medium-duty trucks, whether that’s trucking freight from Los Angeles to New York, or helping keep the lights on in your neighborhood.”

The Ford 6.7-liter Power Stroke diesel engine and Ford TorqShift HD six-speed automatic transmission are designed for medium-duty use and are backed by a five-year/250,000-mile limited warranty and a national network of Ford service centers.

The new 6.7-liter Power Stroke is also 25 percent quieter at 60 mph and up to 45 percent quieter at idle inside the cabin. When standing in front of the grille outside the truck, the engine is 35 percent quieter at idle.

The three diesel power levels available are: 270 horsepower, 675 lb.-ft. torque (best-in-class standard); 300 horsepower, 700 lb.-ft. torque; and 330 horsepower, 725 lb.-ft. torque

The B10 rating is based on the 330-horsepower version of the 6.7-liter Power Stroke.

Multiple ratings provide customers with the flexibility to scale engine power to work applications and operations with no vocational restrictions.

Ford is the only medium-duty truck manufacturer that designs and builds its own diesel engine and transmission combination.
