Throw in 4WD and the F-150 EcoBoost and Silverado 5.3L achieve the exact same FE numbers.

Even though they have the exact same FE numbers, the Ecoboost is able to push out 365 hp and 420 lb-ft of torque while the Silverado makes up to 315 hp and 335 lb-ft of torque. To be able to have an extra 50 hp and 85 lb-ft of torque and still have the same FE numbers is pretty impressive.
