The 2023 Ford F-150’s 2.7L EcoBoost Nano Engine in Review

The Ford F-150 has long been synonymous with power and durability, and the 2.7L EcoBoost engine continues to uphold that legacy in an unexpected way. As a licensed heavy-duty diesel mechanic, I’ve been eager to put this compact yet mighty powerhouse to the test—and let me tell you, it did not disappoint. Some of you have been telling me for months that I needed to review this engine, and now that I have, I can see why it’s making waves in the truck world.

Traditionally, the American truck market leans toward big displacement V8s, but Ford took a bold step with this “Nano” EcoBoost, the smallest engine ever placed in an F-series truck in over 68 years. The result? A highly efficient, robust, and surprisingly powerful engine that defies expectations. Let’s dive in and see what makes the 2.7L EcoBoost stand out.

The Nano: Small But Mighty

Introduced in 2015, the 2.7L EcoBoost—affectionately nicknamed the “Nano”—was designed to offer a balance of power and fuel efficiency. Ford invested a whopping $500 million into the Lima, Ohio, assembly plant to manufacture these engines, which share DNA with their larger 3.5L EcoBoost sibling, but without sharing any actual parts.

Under the hood of the 2023 Ford F-150, this compact V6 delivers an impressive 325 horsepower and 400 lb-ft of torque, matching the output of the larger 5.0L Coyote V8, but achieving peak torque at just 2,700 RPM—a stark contrast to the Coyote’s 4,500 RPM requirement. This means the 2.7L EcoBoost delivers power faster and more efficiently, making it ideal for both work and play.

The twin turbos strapped to this engine crank out a peak 19 PSI of boost, allowing it to achieve cylinder pressures of up to 2,000 PSI. To enhance throttle response and minimize turbo lag, Ford incorporated fully electronic Variable Geometry Turbo (VGT) actuators, ensuring power delivery is quick and seamless across the RPM range.

Built Like a Diesel: Strength and Durability

One of the most surprising aspects of the 2.7L EcoBoost is how much of its design is inspired by diesel engines. From the bottom end to the rotating assembly, this engine is built with durability in mind.

Key diesel-inspired elements include:

Compact Graphite Iron (CGI) Block: Used in heavy-duty diesel applications, CGI offers double the tensile strength and 50% more stiffness compared to traditional cast iron, while being significantly lighter.

Fractured Main Caps: The block and main bearings are cast as a single unit, then fractured to create a perfect fit, enhancing the engine’s structural integrity.

Bowl-Shaped Pistons: Borrowed directly from diesel engine designs, these pistons promote better fuel dispersion and combustion, resulting in increased efficiency and torque output.

Offset Connecting Rods: A design choice typically found in diesel engines, this feature enhances mechanical advantage, improves energy transfer, and reduces friction between the pistons and cylinder walls.

It’s rare to see such robust engineering in a mid-level gasoline engine, making the 2.7L EcoBoost a standout choice for those who demand long-term durability without sacrificing performance.

Efficiency Without Sacrifice

For all its power and strength, the 2.7L EcoBoost also boasts impressive fuel economy. On a recent test run, I was pleasantly surprised by how efficiently it consumed fuel, especially given its turbocharged nature. Ford’s inclusion of both direct and port fuel injection allows for precise control of fuel delivery, reducing carbon buildup while optimizing power output.

Comparing it to traditional V8 options, the EcoBoost engine holds its own, offering a fantastic balance of power and efficiency—something that modern truck owners are increasingly demanding.

Is It Built to Last?

I’ll be the first to admit that I’m usually skeptical of newer, smaller engines—especially when they involve forced induction setups like twin turbos. However, after examining the 2.7L EcoBoost, I can confidently say that it has exceeded my expectations in terms of reliability.

Since its launch in 2015, and the second-generation update in 2018, the engine has proven to be extremely dependable, with no widespread reports of major component failures. Unlike its larger sibling, the 3.5L EcoBoost, which has struggled with cam phaser issues, the 2.7L seems to have sidestepped those pitfalls. Ford’s decision to implement port injection alongside direct injection further contributes to long-term reliability, addressing concerns about carbon buildup that plagued earlier EcoBoost models.

That being said, no engine is perfect, and we’ll dive deeper into potential problem areas in future discussions. But for now, the 2.7L EcoBoost stands as a reliable and robust option in the F-150 lineup.

Performance That Holds Its Own

When it comes to performance, the 2.7L EcoBoost punches well above its weight class. Comparing it to competitors like the 3.0L EcoDiesel from Ram, which delivers similar torque figures, it’s impressive to see how much power Ford has managed to squeeze out of this gasoline engine.

With 139 lb-ft of torque per liter, the 2.7L EcoBoost holds its own against the diesel competition, proving that gasoline-powered trucks can still deliver serious towing power without the complexities and costs associated with diesel engines.

Ford has crafted a gasoline solution that offers diesel-like performance, minus the emissions headaches and complexity that have plagued modern diesel engines.

A Worthy Contender in the Truck World

The 2023 Ford F-150 with the 2.7L EcoBoost is an impressive feat of engineering. With its combination of diesel-inspired durability, excellent fuel economy, and surprising power output, it’s no wonder so many truck enthusiasts have been raving about it. Whether you’re hauling, towing, or just looking for a reliable and efficient daily driver, this engine is a solid choice.

While naturally aspirated V8s may still have an edge in terms of overall longevity, the 2.7L EcoBoost is proving that small displacement, turbocharged engines can hold their own. Only time will tell how it stacks up against its traditional rivals in the long run, but for now, Ford has certainly made a bold statement with the Nano EcoBoost.
