November sales figures are expected to show a seventh consecutive month in which four out of ten Ford F-150 buyers are choosing the EcoBoost V-6 engine over the V-8. The fuel-efficient V-6 EcoBoost is capable of 22 mpg on the highway and 16 mpg in the city. The latest 2011 U.S. Global Quality Research System data shows the quality of trucks with a V-6 equals rates with a V-8.
