F150 2.7 vs 3.5 Ecoboost (Which Ford Engine is Better?)

2.7 vs 3.5 engine

The EcoBoost engine is a relatively new engine offering from Ford and in this article, I will do a comparison between the Ford F150 2.7 vs 3.5 EcoBoost engines.

If you were still trying to figure out which option is for you, then read on. The year 2015 saw the F150 introducing the newer EcoBoost in the form of the 2.7L engine and for this model the 3.5L which Ford had brought into the market earlier on. You may have wondered in a comparison of the two, which would be the better option.

2.7 EcoBoost vs 3.5 EcoBoost

In short, the 3.5l is a better engine than the 2.7l. Comparing the two EcoBoost engines, the 2.7l to the 3.5l you will find that 325 horsepower for the 2.7l is not as powerful as the 365 horsepower from the 3.5l. Both engines have a comparable performance. The 2.7l has better fuel economy than the 3.5l but factor in towing capacity you find the 3.5l is better with significantly higher towing capacity.

Background of the EcoBoost Engine

The 3.5l EcoBoost engine went into production in 2007 with the first one going into a concept Lincoln MKR. It was produced under the name Twin force and later changed to EcoBoost at the Cleveland Plant in 2009.

This engine has undergone numerous improvements with the year 2017 seeing the year’s introduction of the second generation.

The 2.7l EcoBoost went into production with the introduction of the 2015 F150. It saw Ford investing half a billion dollars into their Lima Engine Plant to facilitate its production.

In 2018 Ford came up with the new 2.7L Nano, which is the second generation of the engine boasting higher strength and lighter weight. Also it design and structure of the engine give an extra 25 ft. lb torque.

Towing Capacity:

  • EcoBoost 2.7l: has a maximum towing capacity of about 10 000lbs and Max payload of almost 2500 lbs ·
  • EcoBoost 3.5l: has a maximum towing capacity of around 14 000lbs and a Max payload of 3250lbs. The

The performance of a truck and its towing ability plays a significant row in how well you can expect to perform overtime. And while it would be possible to tow 10 000lbs with the 2.7 it would be best to try and employ the 3.5 instead. The 3.5 is made to handle the more demanding towing task of the two. Over time the 2.7 will feel the strain before the alternative.


The EcoBoost 2.7: comes with 325 horsepower and 375lb. ft in torque giving a fuel economy of about 23 MPG whereas The EcoBoost 3.5: comes with 365 horsepower and 400lb. ft torque with a fuel efficiency of around 20 MPG The 3.5 has the advantage in almost all respects but falls short when it comes to fuel economy.

The 2.7 engine has better engineering than the 3.5 which makes it fuel-efficient but for the practical uses of heavier lifting and requiring more power you find the 3.5 more ideas. It is possible to outfit your 2.7 to bring out the same performance as the 3.5 but that comes at a considerable cost.


Generally, both engines have their issues, the second generation has managed to address many of the problems seen preceding production years. The issues that plague these EcoBoost engines include the following: · A faulty valve guide that resulted in a higher oil consumption ·

The oil pan leak was a result of the difference in materials used to make the pan and the block. The aluminum (engine block) and the plastic (plastic) were made of different materials and held together by an adhesive, which often resulted in leaks.

Carbon Build up because the engines were directly injected and the carbon would build up around the valves over time. · Stretching of the Timing Chain, which caused Timing Chain Issues.

· A faulty Ignition Coil. Ford has made sure the newer engines don’t have these problems and you will see that even repairs for some of these cars for 2015 – 2017 models, the repairs are made by Ford free of charge.

The F150 with either the 2.7 or 3.5 engine is quite reliable and can last you more than 200 000miles. Especially with regular service and maintenance. These vehicles are very durable but care has to be taken with how much you tow.

Conclusion on Ford f150 2.7 vs 3.5 EcoBoost

Both EcoBoost engines are durable and very reliable. The successive improvements in technology mean that the coming generations of these two engines with performing better.

The problems that are in the vehicle have been addressed and you can always count on the F150 to be pretty robust.

Depending on the use and purpose the vehicle is supposed to serve you, you can count on both engines but the 3.5 for heavy-duty performance and the 2.7 for utility tasks.
