The 2011 Ford F-150 has improved fuel economy throughout its lineup, thanks to a new standard V-6, newly offered EcoBoost twin-turbo V-6, and a new V-8 that's both more powerful and more fuel-efficient.
The Dearborn automaker said that it found in a poll of F-150 owners that 70 percent wanted improved fuel economy, and it hopes to conquest more current owners of full-size trucks from the other brands with these higher-mpg offerings.
Ford claims that both the V-6 and V-8 provide best-in-class fuel economy, but the key phrase here is "in the respective segments." However, their claim might be disputed; the figure ties with the highway mileage of the 2011 Chevrolet Silverado Hybrid and 2011 GMC Sierra Hybrid—models that achieve 20 mpg city, 23 highway, for a better EPA combined figure than the F-150. To its defense, Ford assumes—probably correctly—that shoppers looking at the V-6 aren't going to consider the Hybrids; for the V-8, we're not as sure that's true.
With the new 5.0-liter 'Coyote' V-8, the F-150 comes with EPA ratings of 15 mpg city, 21 highway, and the EcoBoost V-6 is expected to do considerably better than that. With the 6.2-liter, it's 12/17.
