Last fall we lauded the arrival of Ford’s twin-turbo, direct-injected 3.5L V-6 offered in the 2011 F-150s.
The new engine is powerful, fuel-efficient and high-tech. All attributes that we long for in a pickup used for both work and play.
But our day in the sun with Ford engineers and their new baby didn’t answer all our questions. The biggest ones being real-world fuel economy and the daily driving experience.
Well, after six months patiently waiting, we finally received a well-appointed EcoBoost F-150 Crew Cab 4×4 Lariat for our own testing. We spent a week putting more than 500 miles on it.
Our truck, which lists for $43,475 as tested, is EPA rated at 16 city/21 highway, nearly identical numbers to the 15/21 fuel economy figures of the GM Flex-fuel (FFV) 5.3L’s and far better than Ford’s 5.0L 14/19.
The EcoBoost, which was equipped with the optional 3.73 axle ratio, averaged 19.4mpg on our 105-mile Interstate test and 15.4mpg in suburban and city driving. Good numbers.
And we expect the EcoBoost would consistently deliver 2-4mpg better fuel economy than any of the other similarly geared V-8 competitors because of its displacement and technology.
