It’s not a revolution in fuel efficiency, but an evolution.
Ford added a wholesome dose of new technologies to the 2017 F-150’s 3.5-liter Ecoboost V6 powertrain, but the significance of the newfound efficiency depends on who you ask. To the people at the Blue Oval, it’s a mileage enhance worthy of celebration. To would-be buyers, it is a minor perk, but inform me more about the torque.
We’ve already detailed the improvements made to the subsequent-generation three.5-liter Ecoboost. Making 375 horsepower and 470 foot-pounds of torque, the revised mill makes several V8s envious. The added energy comes by way of a dual direct and port fuel-injection program that sends fuel to each the intake port and cylinder, turbochargers with lighter turbine wheels and electrically activated wastegates.
Adding to the efficiency, Ford paired the engine with its new 10-speed automatic transmission, a unit co-created by the automaker and General Motors.
What’s the payoff? A solitary mile per gallon. Ford prices rear-wheel-drive F-150 models equipped with the engine at 18 mpg in the city and 25 mpg on the highway, or 21 mpg combined. That’s an enhance of 1 mpg in all three categories.
Four-wheel-drive models return 17 city/23 hwy/20 combined, or an overall achieve of two mpg.
Compared to the base V6 engines of its domestic competition, the rear-drive Ecoboost-powered F-150 matches the highway mileage of the 3.6-liter Ram 1500 (4×2 model), but beats its city mileage by 1 mpg. Ford matches the 4.3-liter Chevrolet Silverado 1500 4×2’s mileage in the city, but beats its highway figure by 1 mpg.
Modest gains if you’re only seeking at displacement, not output. That Ford could wring any mileage improvement out of the engine although delivering a important power enhance is admirable.
Within its own steady, the new powertrain’s combined mileage beats the naturally aspirated 3.5-liter F-150 by 1 mpg, and falls 1 mpg brief of the two.7-liter Ecoboost’s combined figure.
