2011 Ford F150 harley davidson edition

The new engine is now rumored to be slated for models beyond limited-edition trucks like the off-road 2010 F-150 SVT Raptor such as this crew cab model.

The engine will retain Ford's overhead camshaft arrangement, a design Ford adopted in the 90s in search of increased efficiency and refinement. Chrysler uses overhead camshafts for its 4.7-liter V-8, the mid-level engine in its Dodge Ram, but pushrods for its successful HEMI V-8.

With its 2011 F-150, Ford [NYSE:F] is boosting fuel economy by up to 20 percent by going with a fuel-efficient, turbocharged gasoline V-6 as its mainstream engine in the lineup.

Ford hasn't specified exact power or fuel economy figures yet, but we've been told that the engine has been retuned for the F-150, taking advantage of the hoodspace that longitudinal mounting and the huge engine bay allows, as well as stronger truck transmissions, so it power might approach 400 horsepower, along with 400 pound-feet.
With last year's base 4.6-liter V-8 engine rated 15 mpg city, 19 highway in base 2WD form, that could put the EcoBoost F-150's fuel economy as high as 19 mpg city, 23 highway.

4 mpg could make a huge difference
At the top of the lineup is a 6.2-liter V-8, making 411 hp and 434 pound-feet of torque. Unlike the 5.0, this engine has a cast-iron block.
EcoBoost carries 11,300-pound tow rating
And here's the punchline: According to PickupTrucks.com, the new EcoBoost V-6 is rated for towing up to 11,300 pounds—the same as the mammoth 6.2-liter V-8. Base V-6 models can tow up to 6,100 pounds, and the 5.0-liter models will tow close to 10,000 pounds.
