When the 2011 Ford F-150 arrives this Fall, it will reportedly get an all-new powertrain lineup. Ford already officially confirmed several months ago that the light-duty pickups would be getting the first rear-wheel drive application of the 3.5-liter Ecoboost V6. The transaxles in the current Ecoboost applications are torque-limited, so when the twin turbocharged and direct injected V6 lands in the truck, it could produce as much as 400 horsepower and 400 pound-feet of torque.

The current 4.6-liter and 5.4-liter are also expected to be supplanted by the newer, more powerful and efficient engines that debuted in the 2011 Mustang earlier this year. The F-150′s new base engine will reportedly be the 3.7-liter V6 with 305 hp and 280 lb-ft of torque, while the top engine will be the new 5.0-liter Coyote V8. The 5.0-liter will likely be re-tuned from the Mustang’s 412 hp and 390 lb-ft to give it more torque and further elevate the model’s 11,000+ pound towing capacity. The V6-powered trucks could be the first light-duty full-size trucks to hit 25 mpg on the highway, a figure that’s even better than General Motors’ hybrid trucks.
