How To Tell If You Have A 2.7 Or 3.5 Ecoboost

Last Updated on by David Jon

In the realm of vehicle performance and fuel efficiency, knowing whether you’re operating a 2.7 or 3.5 Ecoboost could make a world of difference. It’s crucial because these engine models, produced by the esteemed Ford Motors, come with distinctive features and performance specifications. I’m here to guide you through an uncomplicated process of identifying the type of Ecoboost engine under your hood. With this knowledge, you can confidently make decisions regarding maintenance, performance optimization, fuel consumption, and even potential resale value.


Understanding the EcoBoost Technology

What is EcoBoost?

EcoBoost refers to a series of turbocharged, direct-injection gasoline engines produced by the Ford Motor Company and FEV Engineering. Introduced in 2009, the primary focus of this technology was to deliver impressive power output whilst maintaining remarkable fuel efficiency, hence it’s moniker, a blend of “Economy” and “Boost.”

The Benefits of EcoBoost

The main benefit of EcoBoost engines is fuel economy. By utilising turbocharging and direct fuel injection methods, an EcoBoost engine can give the same performance as a larger, conventional engine whilst consuming less fuel. Additionally, most EcoBoost engines are lightweight, making them excellent choices for compact and subcompact cars, as well as larger vehicles with weight reduction in mind.

How EcoBoost Works in Ford Vehicles

In Ford vehicles, the EcoBoost engine employs two key technologies: direct fuel injection and turbocharging. The direct fuel injection ensures that the precise amount of fuel is delivered into the combustion chamber to maximize fuel usage. On the other hand, the turbocharging technology ensures that more air is forced into the combustion chamber, yielding more power from each fuel drop burnt.

Distinguishing Between the 2.7 and 3.5 EcoBoost

Key Differences in features

The key differences between the 2.7 and 3.5 EcoBoost lie in their size, power and fuel efficiency. Naturally, the 3.5 EcoBoost engine has a larger displacement and, consequently, generates more power than the 2.7. It’s popular in larger models such as the Ford F-150 and the Ford Explorer. The 2.7 EcoBoost, despite being smaller, also provides impressive power. It’s lauded for its good balance between power and fuel efficiency.

Performance Comparison

When it comes to performance, the 3.5 EcoBoost engine undoubtedly has the upper hand. With an impressive horsepower nearing 375 and torque of 470 lb-ft, it outperforms the 2.7 EcoBoost, which generates around 325 horsepower and 400 lb-ft of torque.

Fuel Economy Considerations

The smaller 2.7 EcoBoost engine excels in fuel economy. It performs exceptionally well for a motor of its size, offering a good balance between horsepower and fuel efficiency, which is highly beneficial for everyday driving.
