2015 Ford F-150 Achieves Up to 26 MPG Highway

Aluminum construction, new engines boost economy.

DEARBORN, Michigan - One of the biggest questions around the F-150's switch to aluminum construction was how much the reduced weight would improve the truck's fuel economy. Today officials announced that the 2015 Ford F-150 4x2 equipped with the new 325-hp, 2.7-liter EcoBoost V-6 engine is rated 19 mpg city, 26 mpg highway, and 22 mpg combined. The F-150 with the base, naturally aspirated 283-hp 3.5-liter V-6 is rated 18/25/20 mpg, and the 365-hp, 3.5-liter EcoBoost is rated 17/24/20 mpg. The 385-hp, 5.0-liter V-8 is rated 15/22/18 mpg.

Those numbers reflect rear-wheel-drive trucks. Equipping a 2015 Ford F-150 with four-wheel drive drops the EPA ratings slightly. The 2.7-liter EcoBoost 4x4 scores 18/23/20 mpg , the 3.5-liter V-6 manages 17/23/19 mpg, the 3.5-liter EcoBoost is rated for 17/23/19 mpg, and the 5.0-liter V-8 achieves 15/21/17 mpg with four-wheel drive. Ford charges $495 for the 2.7-liter EcoBoost option versus the standard 3.5-liter naturally aspirated engine.

The 2015 Ford F-150 is considerably more efficient than last year's 2014 Ford F-150. The most efficient version, a 4x2 rear-wheel-drive truck with the 3.7-liter V-6 engine, scored 17/23/19 mpg in EPA testing.

How do these figures compare to rivals? The most efficient version of the 2015 Chevrolet Silverado and 2015 GMC Sierra, rear-wheel-drive trucks with a 4.3-liter V-6 engine, are rated at 18/24 mpg (city/highway). The much smaller 2015 Chevrolet Colorado and 2015 GMC Canyon achieve 20/27 mpg with rear-wheel drive, a six-speed automatic transmission, and the base 2.5-liter inline-four engine. Chrysler Group has the outlier in truck fuel efficiency, as its Ram 1500 EcoDiesel is rated at 20/28 mpg in EPA testing. The most efficient gasoline-powered Ram 1500 hits 17/25 mpg with the truck's 3.6-liter V-6.

Could a diesel engine improve efficiency figures for the 2015 Ford F-150? Ford chief technical officer Raj Nair says the company has the technology to quickly add a diesel to the F-150 lineup if fuel prices dictate (read, rise well beyond $4/gal), but Ford truck marketing manager Doug Scott adds that diesel engine options (for instance the $4,770 EcoDiesel in the Ram 1500) make it uneconomical for half-ton truck buyers.
