Subaru BRZ 2013 Engine: Specs & Performance

The Subaru BRZ 2013 is a fantastic sports car that delivers a thrilling driving experience. A key component of its performance is, of course, its engine. Let's dive into the heart of this machine and explore what powers the 2013 Subaru BRZ.

The FA20: A Boxer Engine Designed for Fun

The 2013 Subaru BRZ is equipped with the FA20 engine, a 2.0-liter naturally aspirated horizontally opposed (or boxer) four-cylinder engine. This engine was co-developed by Subaru and Toyota, with Toyota's contribution being their D-4S direct injection system. The "FA" designation is Subaru's engine family code, and the "20" indicates its 2.0-liter displacement. What makes this engine special is its boxer configuration, where the cylinders are arranged horizontally and oppose each other. This design offers several advantages, including a lower center of gravity, which improves the car's handling and stability. The lower center of gravity contributes to reduced body roll during cornering, enhancing the car's agility and responsiveness.

The FA20 engine in the 2013 BRZ produces around 200 horsepower and 151 pound-feet of torque. While these numbers might not seem overwhelming compared to some modern sports cars, it's the way this power is delivered that makes the BRZ so enjoyable to drive. The engine is naturally aspirated, meaning it doesn't rely on a turbocharger or supercharger to force air into the cylinders. This results in a very linear and predictable power delivery, making it easy to modulate the throttle and control the car's behavior. The engine's responsiveness is particularly noticeable in the mid-range, where it provides ample torque for spirited driving. The high compression ratio of 12.5:1 contributes to the engine's efficiency and power output. This allows the engine to extract more energy from each combustion, resulting in improved fuel economy and performance. The engine also features dual overhead camshafts (DOHC) and four valves per cylinder, which optimize airflow and combustion efficiency. These features help the engine breathe better at high RPMs, allowing it to maintain power throughout the rev range.

The combination of direct and port injection, known as Toyota's D-4S system, further enhances the engine's performance and efficiency. Direct injection sprays fuel directly into the combustion chamber, allowing for more precise fuel control and improved combustion. Port injection, on the other hand, injects fuel into the intake ports, which helps to clean the intake valves and prevent carbon buildup. The D-4S system combines the benefits of both injection methods, resulting in improved power, fuel economy, and reduced emissions. The engine's lightweight construction also contributes to the car's overall agility and handling. The engine block is made from aluminum, which reduces weight and improves thermal conductivity. The lightweight components allow the engine to rev freely and respond quickly to throttle inputs. The FA20 engine is a reliable and durable engine when properly maintained. Regular oil changes, timely maintenance, and avoiding excessive abuse can help ensure the engine's longevity. Overall, the FA20 engine is a well-engineered and enjoyable engine that is perfectly suited for the Subaru BRZ. Its unique boxer configuration, linear power delivery, and responsive nature make it a joy to drive, whether on the street or on the track.

Key Features of the FA20 Engine

To really appreciate the engine in the 2013 Subaru BRZ, let's break down some of its key features:

• Boxer Configuration: As mentioned, the horizontally opposed cylinders give the BRZ a lower center of gravity, improving handling. This design also contributes to smoother engine operation, as the opposing cylinders naturally balance each other out. The reduced vibration translates to a more refined driving experience, especially at higher RPMs. The boxer engine's unique sound is also a defining characteristic, producing a distinctive rumble that sets it apart from other four-cylinder engines.
• Naturally Aspirated: The lack of a turbocharger means instant throttle response and a linear power band. This makes the car predictable and easy to control, especially when drifting or driving on winding roads. The absence of turbo lag allows for immediate power delivery, enhancing the connection between the driver and the car. The naturally aspirated engine also provides a more engaging and visceral driving experience, as the driver can directly feel the engine's response to throttle inputs.
• D-4S Direct Injection: Toyota's direct injection system optimizes fuel delivery for improved power and efficiency. This technology allows for precise control over the fuel-air mixture, resulting in more complete combustion and reduced emissions. The direct injection system also helps to cool the cylinders, which allows for a higher compression ratio and increased power output. The combination of direct and port injection ensures optimal performance across a wide range of driving conditions.
• High Revving: The engine loves to be revved, encouraging drivers to explore the upper reaches of the tachometer. The engine's ability to rev freely to its redline adds to the excitement and engagement of driving the BRZ. The high-revving nature of the engine also contributes to its sporty character, making it feel more responsive and eager to perform. The engine's robust internals and well-engineered valvetrain allow it to withstand the stresses of high-RPM operation.
• Lightweight Design: The engine's components are designed to minimize weight, contributing to the car's overall agility. The lightweight engine improves the car's weight distribution, further enhancing its handling and balance. The reduced weight also allows the car to accelerate more quickly and brake more effectively. The lightweight design of the engine is a key factor in the BRZ's nimble and responsive driving dynamics.

The FA20 engine's design philosophy prioritizes balance, responsiveness, and driver engagement, which aligns perfectly with the BRZ's mission as an affordable and fun sports car. The engine's characteristics make it a joy to drive, whether you're carving through mountain roads or simply cruising around town. The engine's combination of innovative technologies and thoughtful engineering results in a driving experience that is both rewarding and entertaining.
