Leaked: Ford 4.4-Liter Diesel Engine Specs

SANTA MONICA, California — Photos of Ford's new 4.4-liter V8 diesel engine were leaked on the Web, along with some specifications and Ford's rollout plan. According to the accompanying placard, the engine will first become available in the 2010.5 Ford F-150. Following the F-150 application it will extend to the Expedition, Super Duty, Econoline and Lincoln Navigator.

The placard also shows a comparison of the new diesel engine to the current gas-powered 5.4-liter V8. According to Ford, acceleration is about the same, yet the diesel yields a 20 percent increase in fuel mileage, while providing 9 percent more horsepower and 15 percent more torque.

Also described on the placard is the aqueous urea used to make the 4.4-liter a clean diesel. Ford is recommending replenishing the urea at each oil change, and there will also be dash warnings as to when this needs to be refilled. The urea fill port will be inside the fuel filler door.

What this means to you: Getting a diesel in a Ford truck no longer means you'll need to drive a Super Duty. — Kelly Toepke, News Editor
