The lineup of motors is completed by two V6 engines, a 3.7L variant and a 3.5L twin turbo Ecoboost version. These four engines are expected to remain the standard array for the F-150 at least through the end of 2015. The 2011 F-150 has a base cost of $22,970 for the lowest trim and a $51,770 for the highest, plus the cost of add-ons and accessories.
