Understanding Subaru Forester Engines

The Subaru Forester has carved a niche for itself in the compact SUV market. With its rugged design, all-wheel-drive capability, and versatile interior, it’s a favorite among outdoor enthusiasts and families alike. But let’s get real: the engine is the heart of any vehicle, and the Forester is no exception. Understanding the different engine options available can help you make an informed decision, whether you’re looking to buy a new model or just want to know what powers your ride.

Engine Options Over the Years

Subaru has offered various engine configurations throughout the Forester’s production run. From the early models to the latest iterations, the engine choices have evolved significantly. Here’s a quick breakdown of the engine options you might encounter:

• 2.5L Naturally Aspirated Flat-Four (EJ25)


• 2.0L Turbocharged Flat-Four (FA20)


• 2.5L Turbocharged Flat-Four (FB25)


• 2.4L Turbocharged Flat-Four (FB24)

Each of these engines has its own characteristics, strengths, and weaknesses.

2.5L Naturally Aspirated Flat-Four (EJ25)

This engine has been a staple in the Subaru lineup for years. It’s reliable and straightforward, making it a solid choice for daily driving. With around 170 horsepower, it’s not going to win any drag races, but it gets the job done. Its simplicity means fewer things can go wrong, which is a plus for mechanics and DIY enthusiasts.

2.0L Turbocharged Flat-Four (FA20)

The FA20 engine offers a nice balance between power and efficiency. With turbocharging, you get a boost in horsepower, clocking in at around 250 hp. This engine is particularly popular among those who want a bit more zest in their driving experience without sacrificing too much in terms of fuel economy. However, turbo engines can sometimes be more finicky, requiring more maintenance to keep them running smoothly.

2.5L Turbocharged Flat-Four (FB25)

This engine variant is less common but worth mentioning. It combines the reliability of a naturally aspirated engine with the added power of a turbo. With a horsepower rating similar to the FA20, it’s a good option for those who need a bit more grunt for towing or off-road adventures. However, being a turbo, it may require more attention regarding oil changes and cooling systems.

2.4L Turbocharged Flat-Four (FB24)

The latest addition to the Forester lineup, the FB24, is designed for those who crave a powerful yet efficient driving experience. With a horsepower rating that can exceed 260 hp, this engine offers a lively performance while maintaining decent fuel efficiency. It’s a game-changer for those who want a compact SUV that feels more like a sports car. However, keep in mind that with great power comes great responsibility—this engine needs to be cared for properly to avoid premature wear.

Choosing the Right Engine for You

When it comes to selecting the right engine for your Subaru Forester, consider your driving habits and needs.

1. Daily Commute: If you’re primarily driving around town, the 2.5L Naturally Aspirated engine might be the best fit for you.


2. Weekend Warrior: For those who enjoy weekend getaways and light off-roading, the 2.0L Turbocharged engine provides a good balance of power and fuel efficiency.


3. Towing and Heavy Loads: If you plan on towing or carrying heavy loads, consider the 2.5L Turbocharged or the 2.4L Turbocharged engine for their added torque.

Understanding the engine options available in the Subaru Forester can significantly impact your ownership experience. Each engine has its own personality, and knowing what to expect can help you choose the right one for your lifestyle. Whether you prioritize fuel efficiency, power, or reliability, there’s a Subaru Forester engine that fits the bill.
