GR86 & BRZ: Unveiling The Engine Powering These Sports Cars
So, you're curious about what's under the hood of the new GR86 and BRZ, huh? Well, you've come to the right place, guys! Let's dive deep into the heart of these awesome sports cars and explore the engine that makes them tick. We'll break down all the juicy details about its specifications, performance, and why it's such a crucial part of the GR86 and BRZ driving experience. Buckle up, because we're about to get technical (but in a fun way, I promise!).
The Heart of the Beast: The FA24 Engine
Alright, let's get straight to the point. Both the GR86 and BRZ share the same engine: the FA24. This isn't just any old engine; it's a 2.4-liter, naturally aspirated, horizontally opposed four-cylinder engine. Now, that's a mouthful, I know, but let's break it down piece by piece. The 2.4-liter part refers to the engine's displacement, which essentially tells you how much volume the cylinders can hold. More displacement generally means more power. The naturally aspirated bit means that the engine relies solely on atmospheric pressure to fill its cylinders with air, unlike turbocharged or supercharged engines that force air in. Some may complain about it not being turbocharged, but this configuration gives a linear throttle response that many driving purists enjoy.
Horizontally opposed, also known as a boxer engine, is where things get interesting. In this configuration, the cylinders are laid flat on either side of the crankshaft, like a boxer's fists. This design has several advantages. First, it allows for a lower center of gravity, which improves the car's handling and stability. Second, it helps to reduce vibrations, resulting in a smoother and more refined driving experience. The engine is mounted low and far back in the engine bay which helps the car's center of gravity and weight distribution. And finally, the four-cylinder part simply tells you how many cylinders the engine has. Each cylinder houses a piston that moves up and down to convert the energy from combustion into mechanical energy.
FA24 Engine: Power and Performance
Now for the numbers everyone cares about! This FA24 engine delivers around 228 horsepower (231 PS) and 184 pound-feet of torque. That's a significant bump over the previous generation's 2.0-liter engine. Horsepower is a measure of how quickly the engine can do work, while torque is a measure of its rotational force. More torque means better acceleration and pulling power, especially at lower engine speeds. With this increase of power, the car accelerates much more quickly and handles turns better, making the driving experience more satisfying. The increased displacement of the engine also contributed to fixing the 'torque dip' that many owners complained about in the previous generation.
With the FA24 engine, the GR86 and BRZ can sprint from 0 to 60 mph in around 6.1 seconds with the manual transmission and 6.6 seconds with the automatic. That's not supercar territory, but it's plenty quick for a lightweight sports car like these. And more importantly, the engine provides a responsive and engaging driving experience that makes you feel connected to the road. It's an engine that loves to be revved, encouraging you to explore the upper reaches of the tachometer. The power band is broad and accessible, making the car easy to drive in everyday situations while still offering plenty of thrills when you want to push it harder. This makes it a very versatile and enjoyable car to own.
Engine Technology and Features
The FA24 engine in the GR86 and BRZ isn't just about raw power; it's also packed with clever technology and features that enhance its performance and efficiency. For example, it uses direct injection, which sprays fuel directly into the cylinders for more precise fuel delivery and improved combustion. This helps to increase power, reduce emissions, and improve fuel economy. It uses an electronic throttle control system, which provides precise and consistent throttle response.
The engine also features a high compression ratio, which helps to extract more energy from the fuel. However, this also means that the engine requires premium gasoline to prevent knocking or pinging. The engine also features a lightweight design, thanks to the use of aluminum alloy for the cylinder block and cylinder heads. This helps to reduce the overall weight of the car, which improves its handling and agility. It also contributes to better fuel economy. The FA24 engine is designed to be as efficient and reliable as possible.
Why This Engine Matters
So, why is this FA24 engine such a big deal for the GR86 and BRZ? Well, for starters, it addresses one of the biggest criticisms of the previous generation: the lack of power and torque. The old 2.0-liter engine was criticized for its torque dip, which was a noticeable dip in power in the mid-range that made the car feel sluggish. The new 2.4-liter engine eliminates this torque dip, providing a much smoother and more linear power delivery. This makes the car more enjoyable to drive in a wider range of situations. In addition to the increased displacement, changes were made to the intake, exhaust, and fuel delivery system to improve the overall performance of the engine. The new engine provides a noticeable improvement in acceleration and responsiveness.
But more than just the numbers, the FA24 engine perfectly complements the GR86 and BRZ's lightweight chassis and rear-wheel-drive configuration. It provides the right amount of power to make the car feel playful and engaging without being overwhelming. It's an engine that encourages you to explore the car's limits and hone your driving skills. It's also an engine that's relatively simple and reliable, which means less maintenance and more time on the road. The new engine is a testament to the idea that you don't need a ton of horsepower to have fun driving a car.
More Than Just an Engine: The Complete Package
Of course, the engine is only one part of the equation. The GR86 and BRZ are also renowned for their sharp handling, precise steering, and communicative chassis. These cars are designed to be driver-focused, providing a direct and unfiltered connection to the road. The suspension is firm but not harsh, providing a good balance between comfort and control. The brakes are strong and responsive, inspiring confidence when you need to stop quickly. The interior is simple and functional, with everything you need and nothing you don't. The seats are supportive and comfortable, keeping you in place during spirited driving. The driving position is excellent, with a clear view of the road ahead.
And while the GR86 and BRZ are primarily performance cars, they're also surprisingly practical. They offer a decent amount of trunk space for their size, and the rear seats can be folded down to accommodate larger items. They're also relatively fuel-efficient, especially if you resist the urge to drive them flat-out all the time. The cars come standard with a variety of safety features, including airbags, stability control, and traction control. Overall, the car is a well-rounded package that provides an enjoyable driving experience.
Final Thoughts: A Winning Combination
In conclusion, the FA24 engine is a fantastic addition to the GR86 and BRZ. It provides a significant boost in power and torque over the previous generation, while also maintaining the car's signature balance and agility. It's an engine that's both fun and rewarding to drive, making these cars a true joy to own. It's also a reliable and relatively affordable engine, making the GR86 and BRZ accessible to a wider range of enthusiasts. If you're looking for a sports car that's engaging, affordable, and a blast to drive, the GR86 and BRZ should definitely be on your list. The combination of the FA24 engine and the car's other features make it a winning combination.
