2015 Subaru BRZ Engine: Specs & Performance
Hey car enthusiasts! If you're curious about what's under the hood of the 2015 Subaru BRZ, you've come to the right place. Let's dive into the specifics of the engine that makes this sporty coupe tick. The 2015 Subaru BRZ is equipped with a 2.0-liter naturally aspirated four-cylinder boxer engine. This engine is part of the FA engine family developed by Subaru. Known for its horizontally opposed design, this engine configuration helps to keep the car's center of gravity low, enhancing handling and stability. This is a key feature that contributes to the BRZ's reputation as a fun and nimble sports car. The engine delivers a balance of performance and efficiency, making it a popular choice for those who want an engaging driving experience without sacrificing fuel economy.
The boxer engine, also known as a flat engine, has its cylinders arranged horizontally, with pistons moving towards and away from each other in a punching motion – hence the name 'boxer.' This design offers several advantages. First, the low, flat layout helps to lower the car's center of gravity, which improves handling. Second, the symmetrical movement of the pistons helps to reduce engine vibration, resulting in a smoother and more refined driving experience. In the 2015 Subaru BRZ, the 2.0-liter boxer engine produces around 200 horsepower and 151 lb-ft of torque. While these numbers might not sound like a lot compared to some high-performance sports cars, the BRZ's lightweight design and responsive chassis make the most of this power. The engine's high-revving nature encourages drivers to explore the upper reaches of the RPM range, adding to the excitement of driving. The engine is paired with either a six-speed manual or a six-speed automatic transmission. The manual transmission is favored by enthusiasts for its direct feel and greater control, while the automatic offers convenience and ease of use.
Beyond the basic specs, the engine in the 2015 BRZ features advanced technologies such as direct injection and dual overhead camshafts (DOHC). Direct injection helps to improve fuel efficiency and power output by injecting fuel directly into the combustion chamber, allowing for more precise control over the air-fuel mixture. The DOHC design allows for more precise control over valve timing, which further enhances engine performance and efficiency. These technologies, combined with the engine's lightweight construction and optimized design, contribute to the BRZ's overall performance and fuel economy. The Subaru BRZ isn't just about straight-line speed; it's about the overall driving experience. The engine's responsiveness, combined with the car's balanced handling and communicative steering, makes it a joy to drive on twisty roads. Whether you're a seasoned enthusiast or a novice driver, the BRZ offers a rewarding and engaging driving experience that's hard to find in other cars in its class.
Diving Deeper: Engine Specifications
Let's get into the nitty-gritty details. The 2015 Subaru BRZ boasts a 2.0-liter FA20 flat-four engine. This engine isn't just any four-cylinder; it's a boxer engine, meaning the cylinders are horizontally opposed. Think of it like two separate engines working together, canceling out vibrations and lowering the center of gravity. This is a huge part of why the BRZ handles so well. The engine has a square bore and stroke of 86mm x 86mm, contributing to its rev-happy nature. It's designed to be driven hard and loves to be pushed to the redline. The compression ratio is 12.5:1, which is relatively high and helps to improve efficiency and power output. This high compression ratio requires the use of premium gasoline to prevent knocking and ensure optimal performance. The engine also features dual overhead camshafts (DOHC) and four valves per cylinder, allowing for more precise control over the intake and exhaust processes. This helps to optimize airflow and improve engine breathing, resulting in better power and torque.
The FA20 engine also incorporates direct fuel injection, which sprays fuel directly into the combustion chamber rather than into the intake manifold. This allows for more precise control over the air-fuel mixture, resulting in improved fuel efficiency and reduced emissions. The direct injection system also helps to cool the cylinders, which allows for a higher compression ratio without the risk of knocking. The engine is equipped with a dual Active Valve Control System (AVCS), which independently adjusts the intake and exhaust valve timing based on engine speed and load. This helps to optimize engine performance across a wide range of driving conditions, from low-speed cruising to high-speed acceleration. The AVCS system also helps to improve fuel efficiency and reduce emissions.
In terms of power output, the 2015 Subaru BRZ produces around 200 horsepower at 7,000 RPM and 151 lb-ft of torque at 6,400 RPM. While these numbers might not seem earth-shattering, it's important to remember that the BRZ is a lightweight car, weighing in at around 2,800 pounds. This low weight allows the BRZ to accelerate quickly and handle nimbly. The engine is paired with either a six-speed manual or a six-speed automatic transmission. The manual transmission is the preferred choice for enthusiasts, as it offers a more direct and engaging driving experience. The automatic transmission, on the other hand, offers convenience and ease of use, making it a good choice for daily driving. Regardless of the transmission, the engine delivers a fun and rewarding driving experience. The BRZ's engine is designed to be reliable and durable, with many owners reporting few issues even after years of ownership. Regular maintenance, such as oil changes and spark plug replacements, is essential to keep the engine running smoothly and prevent any potential problems. Overall, the 2.0-liter FA20 engine in the 2015 Subaru BRZ is a well-engineered and reliable powerplant that provides a great balance of performance, efficiency, and durability.
Performance and Driving Experience
When it comes to the 2015 Subaru BRZ, it's not just about the engine specs; it's about how all the components work together to create a unique driving experience.

Reliability and Maintenance
When considering the 2015 Subaru BRZ, reliability and maintenance are important factors. The 2.0-liter FA20 engine is generally considered to be reliable, but like any engine, it requires regular maintenance to keep it running smoothly. One of the most important maintenance tasks is regular oil changes. The engine should be serviced with high-quality synthetic oil at the recommended intervals, typically every 6,000 miles or six months, whichever comes first. It's also important to check the oil level regularly and top it off as needed, as the engine can consume oil, especially during spirited driving. Another important maintenance task is spark plug replacement. The spark plugs should be replaced at the recommended intervals, typically every 60,000 miles. Worn spark plugs can cause the engine to misfire, resulting in reduced performance and fuel economy.
In addition to these basic maintenance tasks, it's also important to keep an eye on other potential issues. One common issue with the FA20 engine is carbon buildup on the intake valves, which can result in reduced performance and fuel economy. This issue is more common in engines that are driven primarily in city conditions or that are not driven hard enough. To prevent carbon buildup, it's recommended to occasionally drive the car hard and use a fuel system cleaner to help keep the intake valves clean. Another potential issue is a faulty fuel pump, which can cause the engine to stall or run poorly. If you experience any of these symptoms, it's important to have the fuel pump checked by a qualified mechanic. The Subaru BRZ is a relatively simple car, which makes it easier to maintain and repair. However, it's still important to find a qualified mechanic who is familiar with the car and its engine.
Overall, the 2015 Subaru BRZ is a reliable car that can provide years of trouble-free service with proper maintenance. By following the recommended maintenance schedule and keeping an eye on potential issues, you can help to ensure that your BRZ stays running smoothly for many years to come. Regular maintenance, such as oil changes and spark plug replacements, is essential to keep the engine running smoothly and prevent any potential problems. With proper care and maintenance, the 2015 Subaru BRZ can be a reliable and enjoyable sports car for many years to come. The BRZ's engine is designed to be reliable and durable, with many owners reporting few issues even after years of ownership.
