We'll be covering everything from its displacement and configuration to its performance characteristics and how it contributes to the car's overall driving dynamics. Get ready, because we're about to get technical, but in a way that's totally understandable and, dare I say, exciting!

The Heart of the Beast: The Boxer Engine

Alright, so the big question: What engine is in the Subaru BRZ? Well, for both generations of the BRZ, Subaru has stuck with what they do best – a boxer engine. Now, if you're not familiar with the term, a boxer engine, also known as a horizontally opposed engine, is a unique type of internal combustion engine where the pistons move towards each other simultaneously. Think of them like boxers punching each other – hence the name! This design has some pretty sweet advantages, especially for a car like the BRZ that's all about nimble handling and a low center of gravity. Unlike inline-four or V-engines where the pistons move up and down, the boxer setup lays the cylinders flat, almost like a pancake. This layout allows the engine to sit much lower in the chassis. Why is that a big deal? Because a lower center of gravity means the car is more stable, corners flatter, and generally feels more planted and responsive when you're throwing it around some twisty roads. It's a key ingredient in the BRZ's legendary handling characteristics, making it feel incredibly connected to the tarmac. So, when we talk about the Subaru BRZ engine, we're talking about a piece of engineering that's fundamental to its driving experience, contributing significantly to its agility and sporty feel on the road. It's not just about horsepower; it's about how that power is delivered and how the engine's physical placement impacts the entire vehicle's dynamic capabilities, making it a standout in its class for drivers who prioritize a connected and engaging driving feel.

First Generation BRZ Engine: The FA20

Let's rewind a bit and talk about the first generation Subaru BRZ, which debuted around 2012. The engine that powered these beauties was the Subaru FA20, a 2.0-liter naturally aspirated flat-four engine. Now, naturally aspirated means it doesn't have a turbocharger or supercharger forcing extra air into the cylinders. It relies solely on the engine's displacement and design to generate power. This was a deliberate choice by Subaru and Toyota (who co-developed the BRZ and its twin, the Toyota 86/Scion FR-S). They wanted the BRZ to have a linear power delivery, meaning the acceleration felt smooth and predictable as the revs climbed. There were no sudden surges of power like you might get with a turbocharged engine. This made the car incredibly rewarding to drive, especially for those learning to drift or looking for precise throttle control. The FA20 in the first-gen BRZ produced around 200 horsepower (give or take a few depending on the model year and market), paired with about 151 lb-ft of torque. While these numbers might not sound earth-shattering compared to some modern muscle cars, they were more than enough for the BRZ's lightweight chassis. The focus was on keeping the car light and agile, and the FA20 perfectly complemented that philosophy. Its compact size and relatively low weight also contributed to the excellent weight distribution, further enhancing the car's handling prowess. The engine's characteristic boxer rumble is also part of its charm, giving it a distinct sound that enthusiasts love. So, for those of you looking at the older BRZ models, the FA20 is the engine you'll find, offering a pure, naturally aspirated driving experience that's becoming increasingly rare in today's automotive landscape, making it a gem for purists.

Second Generation BRZ Engine: The FA24 (A New Era)

Fast forward to the second generation BRZ, launched for the 2022 model year, and Subaru gave the BRZ a significant upgrade under the hood. The Subaru FA24 engine is the star here. This is also a 2.4-liter naturally aspirated flat-four boxer engine, but it's a much more potent iteration than its predecessor. Subaru increased the displacement from 2.0 liters to 2.4 liters, and importantly, they gave it more torque. This is a huge deal for a car like the BRZ. While the horsepower saw a respectable bump to around 228 hp, the real game-changer is the torque figure, which jumped to about 184 lb-ft. This might not sound like a massive leap on paper, but in practice, it makes a world of difference. That extra grunt, especially in the lower and mid-range of the RPM band, means the car feels significantly punchier. You have more pulling power when accelerating from a standstill, more responsiveness when you need to overtake, and critically, more torque available for drifting or sliding around corners. The FA24 maintains that desirable linear power delivery of the FA20, so it's still a joy to rev out, but now it has the low-end and mid-range oomph that was sometimes criticized in the first generation. Subaru achieved this by increasing the bore and stroke of the engine and refining its intake and exhaust systems. They also managed to keep the engine's weight and size comparable to the FA20, so the legendary handling characteristics of the BRZ are preserved, if not enhanced. The FA24 represents a thoughtful evolution, addressing the previous generation's power deficit without compromising the core driving experience that makes the BRZ so special. It's a brilliant example of how a slightly larger, more torquey engine can elevate an already fantastic sports car into something even more compelling for enthusiasts who demand both sharp handling and satisfying acceleration.

Naturally Aspirated vs. Turbocharged: The BRZ Philosophy

One of the most debated topics among car folks is the choice between a naturally aspirated (NA) engine and a turbocharged engine. So, why does the Subaru BRZ use a naturally aspirated engine? Well, it boils down to the BRZ's core philosophy: driving purity. Subaru and Toyota wanted the BRZ to be a car that connects the driver directly to the road, offering a predictable and engaging experience. Naturally aspirated engines are known for their linear power delivery. This means that as you press the accelerator, the power builds smoothly and progressively. There are no sudden bursts or turbo lag to contend with. This predictability is fantastic for several reasons. Firstly, it allows for more precise control of the throttle, which is crucial for performance driving, especially for techniques like drifting or cornering at the limit. You know exactly how the car will respond to your inputs. Secondly, it makes the car feel more immediate and alive. The engine revs eagerly, and the sound builds organically, creating a more visceral connection between the driver and the machine. Turbocharged engines, while offering more power for their size and often better fuel economy, can introduce complexities like turbo lag (a delay between pressing the accelerator and the turbo kicking in) and a less linear power curve. While modern turbochargers have minimized lag significantly, the fundamental character of power delivery is different. Subaru's decision to stick with naturally aspirated engines for the BRZ emphasizes the joy of the driving process rather than just the raw numbers. It's about the skill of managing the engine's revs, feeling the car respond, and enjoying the mechanical feedback. This commitment to an engaging, analogue driving experience is what sets the BRZ apart in a world increasingly dominated by turbocharged and electrified powertrains. It's a choice that resonates deeply with driving purists who value feedback, control, and the sheer enjoyment of operating a well-balanced machine. It’s about the feel and the engagement, guys, not just how quickly you can get to 60 mph.

Engine Placement and Handling Benefits

We've touched on it before, but let's really hammer home how the engine placement in the Subaru BRZ contributes to its legendary handling. As mentioned earlier, the boxer engine's design allows it to sit extremely low in the chassis. This isn't just a minor tweak; it's a fundamental design choice that drastically lowers the car's center of gravity. Think about physics: the lower an object's center of gravity, the more stable it is. For a sports car like the BRZ, this translates into incredible benefits when you're navigating corners. When you turn the steering wheel, a lower center of gravity means less body roll. The car stays flatter through the corner, allowing your tires to maintain maximum grip. This makes the BRZ feel incredibly agile and responsive. You can make quick directional changes with confidence, and the car feels glued to the road. Furthermore, Subaru and Toyota worked hard to achieve near-perfect 50/50 weight distribution between the front and rear axles. The boxer engine's compact and balanced nature is key to achieving this ideal distribution. Having the weight evenly spread front-to-back means that both the front and rear tires work more effectively, providing balanced grip and predictable handling characteristics. Whether you're accelerating, braking, or cornering, the car feels neutral and composed. This balanced setup is what makes the BRZ so forgiving and fun to drive at the limit. It doesn't have a tendency to suddenly push wide (understeer) or snap into oversteer without warning. Instead, it communicates clearly with the driver, letting you know what it's doing. The low engine placement and ideal weight distribution work in perfect harmony, creating a driving experience that is pure, engaging, and confidence-inspiring. It's a testament to clever engineering where every component, especially the engine, is chosen and placed to optimize the driving dynamics for maximum fun on both the street and the track. It truly is a masterclass in sports car packaging and design, guys!
