2.7L EcoBoost Vs. 3.5L EcoBoost Vs. 5.0L V8: Detailed Comparison

It is natural to be confused while making a choice between the 5.0L V8, 2.5 EcoBoost, and 3.5 EcoBoost. They have been designed to withstand regular and extreme off-road driving situations. Let’s go into the details of the specifications of each engine according to the table above. 

Engine Performance

Winner: 3.5L EcoBoost

It’s not so easy to pick a champion in this category. But we pick the 3.5L EcoBoost. This dual-injection gasoline engine can offer a seamless driving experience and produce fewer greenhouse gases. The 3.5L EcoBoost is reliable enough to power full-sized cars, supercars, pickup trucks, and utility vehicles.

The 5.0L V8 is not too far behind. This 8-cylinder naturally aspirated Aluminum block machine has maintained its solid reputation for decades. It has a higher horsepower rating while the EcoBoost 3.5L boasts of greater torque.

The 2.7L EcoBoost is also not bad at all. It still supplies enough torque and energy for several use cases. It also has a direct-injection design and twin-turbo system like the 3.5L EcoBoost. You can pair all three engines with four-wheel drive or rear-wheel drive. With a few mods and tuners, you can squeeze more power out of any of the three engines.

Winner: 3.5 EcoBoost

The 3.5 EcoBoost has a towing capacity of 13,200 lbs. This beast also has the advantage of a larger displacement. Engine displacement is the concentration of fuel/air mixture that an engine can absorb during a full combustion cycle.

However, the V8 is close, with a towing capacity of 11,600lbs. This masterpiece also has an impressive payload capacity of about 3,2700 lbs.

The 2.7L EcoBoost can only tow heavy loads up to 9,100 lbs. To support any weight slightly higher on steep terrain, it will have to rely more on its turbo system. The result is the generation of a considerable amount of heat. However, the 2.7 and 3.5 EcoBoost have been designed to withstand sufficient tension while towing.

Let’s see the owners’ opinions about these engines’ towing capacity.

“I am a huge fan of the 2.7L, and it can tow anything you would reasonably put behind an F150, although many are not reasonable on that regard. With that in mind, as others have mentioned the 2.7L is limited in how much Ford will let you option it out when tied to the 2.7L. […] I have towed some heavy trailers with my 2019, and it was fantastic. TFL did Ike Gauntlet runs with the 2.7L, and it performed better than the V8 counterparts from other brands. It’s an incredible engine.”

“Any of the 3 will get the job done. The 3.5 will tow a heavier travel trailer the easiest. Since you don’t know specifics now about a future travel trailer’s weight, the safest thing to do is err to buying the most capable truck, which is a 3.5 max tow. […] keep in mind I am usually a fairly conservative driver.”

Fuel Economy

Winner: 2.7 EcoBoost

The 2.7 EcoBoost is arguably the winner in this category. It has an estimated fuel economy of 20 MPG and 26 MPG in the city and highway, respectively. This is because of its lower displacement and horsepower rating. In reverse, the 3.5 EcoBoost rates at 18 MPG in the city and 25 MPG in the highway. The 5.0 V8 engine has the lowest fuel economy rating among three with 17 MPG and 23 MPG in the city and highway, respectively.

Additionally, the rate of fuel consumption still depends on certain factors. The answer to the questions below influences your fuel economy.

  • What do you do with your vehicle? Do you use it for daily commuting or heavy towing?
  • How aggressive is your driving technique?
  • Is your truck rear-wheel drive or four-wheel drive? For example, 4WD Ford vehicles are known to have a lower MPG compared to 2WD variants.

Engine Longevity

Winner: 3.5L EcoBoost

The longevity of these three engines is subject to a tight debate. It is not easy to predict the exact lifespan of an engine. Although, these three Ford powerhouses have proven to be reliable without many issues.

With regular maintenance and careful driving, the F150 2.7 EcoBoost can cover 200,000 to 230,000 miles. The 3.5L EcoBoost should be able to reach a mileage of 250,000 miles. You need to use high-quality synthetic oil for both EcoBoost machines.

Regular lubrication will reduce the formation of carbon residue within their combustion system. You need to wash or replace the direct fuel injectors at regular intervals. The spark plugs and transmission fluid also need timely replacement.

As for the 5.0L V8, it should be able to hit a mileage of 200,000 miles. Note that poor driving technique, bulky off-road add-ons, and intensive engine modifications can cut down your engine’s lifespan.

Available Trim

Winner: 5.0L V8
