Which F-150 engine is most fuel-efficient?

The most fuel-efficient engine option for the Ford F-150 pickup truck is the 2.7-liter EcoBoost V6 engine. This turbocharged engine delivers impressive fuel economy without sacrificing power and capability, making it a popular choice among F-150 buyers.


Fuel Efficiency Breakdown


The 2.7-liter EcoBoost V6 engine in the Ford F-150 is rated at an EPA-estimated 20 mpg in the city and 26 mpg on the highway, for a combined fuel economy of 22 mpg. This is the highest fuel efficiency rating among all the available engine options for the F-150, which include larger V6 and V8 engines as well as a diesel option.


The key factors that contribute to the 2.7-liter EcoBoost's impressive fuel efficiency are its smaller displacement, turbocharging, and advanced engine technologies. The smaller 2.7-liter engine size means it uses less fuel than larger V6 and V8 options, while the turbocharger helps it deliver the power and performance of a larger engine when needed.


Power and Capability


Despite its focus on fuel efficiency, the 2.7-liter EcoBoost engine is no slouch when it comes to power and capability. It produces 325 horsepower and 400 lb-ft of torque, allowing the F-150 to tow up to 8,500 pounds and haul up to 2,480 pounds of payload. This makes it a versatile choice for those who need the utility of a full-size pickup truck without sacrificing fuel economy.


Other Fuel-Efficient Options


While the 2.7-liter EcoBoost is the most fuel-efficient engine in the F-150 lineup, there are a few other options that also deliver good fuel economy:



  • 3.3-liter V6 engine: 19 mpg city, 25 mpg highway, 22 mpg combined

  • 3.0-liter Power Stroke diesel engine: 22 mpg city, 30 mpg highway, 25 mpg combined

  • 5.0-liter V8 engine with Ford's Auto Start-Stop technology: 17 mpg city, 23 mpg highway, 19 mpg combined


These alternative engine choices may be better suited for those who need more towing capacity or prefer a traditional V8 engine, while still maintaining respectable fuel efficiency.p>

In summary, the 2.7-liter EcoBoost V6 engine is the most fuel-efficient option in the Ford F-150 lineup, delivering an EPA-estimated 22 mpg combined fuel economy without sacrificing power or capability. This makes it a popular choice for F-150 buyers who want the utility of a full-size pickup with improved fuel efficiency.

What is the better engine, 5.0 or 3.5 EcoBoost?


When comparing these two engines, the 3.5L EcoBoost V6 offers more torque and slightly better fuel economy than the 5.0L Ti-VCT V8. Surprisingly, the bigger V8 provides slightly less payload capacity, but it's easier to maintain and is more ideal for lengthy periods of heavy workload.



Which engine is better, 2.7 or 3.5 EcoBoost?


When it comes to fuel efficiency, the 2.7L engine takes the crown. Its lighter weight and efficient design allow for better mileage, making it the perfect option for drivers concerned about long-term fuel costs. The 3.5L engine, while powerful, consumes more fuel, especially when towing.

  • 2013 – 2015.



At what speed is a F-150 most fuel-efficient?


65 mph
The most obvious way to save gas when driving your F150 is to limit abrupt acceleration and braking. For the best efficiency, limit your speeds to 65 mph.
