Davis Bellew As a Subaru owner, you may have wondered what powers your vehicle under the hood. Subaru is known for its reliable and innovative engines, and each model comes with a unique set of characteristics and performance capabilities. Whether you are a prospective buyer, current owner, or car enthusiast, understanding the engine in your Subaru is essential.
Types of Engines Found in Subarus
Subarus are equipped with two types of engines: Boxer engines and conventional in-line engines. The Boxer engine, also known as the flat engine, was introduced by Subaru in the 1960s and has since become the signature feature of the brand. The Boxer engine delivers a low center of gravity, resulting in better handling and overall balance.
The in-line engine, on the other hand, is typically found in other car models and has a narrower block. This type of engine is less common in Subarus but is still used in some models.
Boxer Engines in Subarus
Subaru Boxer engines have a unique design where the engine is horizontally-opposed, with pistons facing each other. This design allows for a more uniform distribution of power, creating a smoother and more balanced ride. Boxer engines also have a lower center of gravity, which improves the vehicle’s stability and reduces body roll.
Subaru currently offers four Boxer engines: the EJ, FA, FB, and EZ. The EJ engine, which has been used in various models since 1989, is known for its high-performance capabilities with horsepower ranging from 200 to 320.
The FA engine, introduced in 2012, is more fuel-efficient and is used in the Impreza and Crosstrek models. The FB engine, introduced in 2011, is used in the Legacy, Impreza, Forester, and Outback models and is known for its smooth and quiet performance.
Finally, the EZ engine, used in the Tribeca model, is a larger and more powerful engine than the other options and delivers an impressive 256 horsepower.
Power and Performance Specifications
When it comes to Subaru engines, horsepower and torque are two of the most essential performance indicators. Horsepower refers to the maximum power a car’s engine can produce, while torque refers to the engine’s twisting force, which is necessary for acceleration.
The horsepower of Subaru Boxer engines ranges from 152 to 310, while the torque ranges from 145 to 290 lb-ft. These numbers can vary depending on the engine type and the model of the car.
Subaru engines are also known for their exceptional all-wheel-drive system, which provides better traction and stability on the road. The all-wheel-drive system ensures that power is consistently distributed to all four wheels, making it easier to handle difficult terrain and adverse weather conditions.
Fuel Efficiency
Fuel efficiency is a critical factor that impacts the cost of ownership over the lifetime of the vehicle. Subaru engines are designed to be more fuel-efficient, with some models delivering up to 33 mpg on the highway.
The fuel efficiency of a Subaru engine is affected by several factors, including the engine size, the driving conditions, and the driving style of the owner. Boxer engines, while known for their superior performance, require more maintenance and may consume more oil than other engines.
Potential Problems
Like all cars, Subarus may experience issues with their engines over time. Some common problems with Subaru engines include head gasket failures, oil leaks, and excessive oil consumption. Regular maintenance, including oil changes, can help prevent these issues from occurring.
Which Engine is Right for You?
When it comes to choosing the right engine for your Subaru, it depends on your personal preferences and needs. If you prioritize performance, the EJ or EZ engine may be the best option. If fuel efficiency is essential, the FA engine may be the better choice. The outback models feature the FB engine that is known for its smooth and quiet performance.
Conclusion
Subaru engines are known for their innovative designs, exceptional performance, and reliability. Understanding the type of engine in your Subaru and its capabilities can help you make informed decisions about maintenance and repairs. We hope this guide has helped demystify the engine in your Subaru and given you a better understanding of its design, performance capabilities, and potential issues.
