The Toyota GR86 and Subaru BRZ share a close mechanical bond, but each brand frames the experience differently. Under the sheetmetal, the heart of the BRZ is a tuned flat-four engine built for responsive handling and engaging dynamics.
Below is a concise snapshot of the engine lineup and key figures you will encounter across recent BRZ generations.
| Model Year | Engine Code | Configuration | Horsepower | Torque |
|---|---|---|---|---|
| 2019–2020 BRZ | 4U-GSE | Naturally Aspirated Flat-Four | 200 hp @ 7,000 rpm | 151 lb-ft @ 6,400 rpm |
| 2021–2023 BRZ | 4U-GSE | Naturally Aspirated Flat-Four | 228 hp @ 7,000 rpm | 184 lb-ft @ 6,400 rpm |
| 2024+ BRZ | FA24D | Direct Injection Flat-Four Turbo | 228 hp @ 5,800 rpm | 258 lb-ft @ 4,400–5,200 rpm |
| 2024+ BRZ TR69 | FA24F | Naturally Aspirated Flat-Six | 394 hp @ 7,400 rpm | 266 lb-ft @ 6,800 rpm |
| 2024+ BRZ STI19 | FA24G | Direct Injection Flat-Four Turbo | 310 hp @ 5,800 rpm | 290 lb-ft @ 4,400–5,200 rpm |
2019–2023 Naturally Aspirated 200 and 228 HP Four
For the first several model years, the standard BRZ relied on the 4U-GSE, a Toyota-sourced naturally aspirated flat-four. This engine emphasized a linear power band and high-revving character, with peak power at 7,000 rpm and strong midrange pull that matched its sporty temperament.
In 2021, a modest power bump to 228 hp and 184 lb-ft arrived without changing the fundamental architecture. Engineers adjusted the intake and exhaust systems along with calibration, giving the BRZ more usable throttle response while preserving its nimble, well-balanced chassis dynamics.
Because the 4U-GSE sits low and far back in the platform, the BRZ maintains a near 50/50 weight distribution and a low center of gravity. This layout is central to the car’s precise steering, quick turn-in, and driver-focused feel on both backroads and canyon runs.
2024 Direct Injection Turbo Upgrade
The 2024 model year introduced the FA24D, a direct-injected, turbocharged flat-four that raised output to 228 hp while delivering stronger low-end torque. The addition of turbocharging and D-4S injection broadens the power curve, making the BRZ more flexible for daily driving without sacrificing its engaging personality.
Peak torque now appears between 4,400 and 5,200 rpm, reducing the need to constantly rev the engine to access strong acceleration. The FA24D retains a rear-biased weight balance, so the turbo boost complements rather than overpowers the chassis’s agile character.
This update reflects a broader industry trend toward downsized, efficient powertrains that still support spirited driving. For enthusiasts, the turbo BRZ offers extra practicality for longer trips and stoplight sprints while staying true to the platform’s handling roots.
Performance Frontier Flat-Six Option
The highest-performance BRZ variant shifts away from the classic flat-four layout with a horizontally opposed six-cylinder. The FA24F flat-six in the TR69 produces 394 hp and 266 lb-ft, placing the BRZ in a different performance class without abandoning its rear-drive platform.
Mounted behind the front axle, this flat-six retains a rearward bias that keeps the handling balanced and predictable. Combined with enhanced suspension components and limited-slip differentials, it turns the BRZ into a track-focused machine capable of quick lap times and confident cornering.
For drivers who want the excitement of a wider, more powerful engine while keeping the BRZ’s compact proportions and precise feedback, the six-cylinder option delivers a compelling blend of usability and performance.
Key Takeaways for Choosing the Right BRZ Engine
- The 4U-GSE remains a favorite for its high-revving, naturally aspirated character and balanced chassis dynamics.
- The 2021 update added 28 hp and 33 lb-ft, improving everyday usability without altering the core driving feel.
- The 2024 FA24D turbo brings more low-end torque and flexibility, ideal for mixed urban and backroad use.
- The FA24F flat-six TR69 is best for enthusiasts who want maximum performance and a race-inspired experience.
- Consider your daily driving needs, desired power delivery, and whether track capability matters when choosing between trims.
FAQ
Reader questions
Does the BRZ come with a manual transmission, and how does it affect the engine response?
Yes, the BRZ is available with a six-speed manual transmission that is closely matched to the engine, giving you direct control over revs and acceleration. The manual layout enhances throttle response and makes it easy to keep the engine in its optimal power band, especially on winding roads and during spirited driving.
How does the turbocharged FA24D compare to the older naturally aspirated 4U-GSE in everyday use?
The FA24D provides more low-end torque and a broader power band, which makes street driving smoother and reduces the need to downshift frequently. The 4U-GSE, by contrast, rewards higher revs with a more linear, buzzy character that many enthusiasts associate with the earlier BRZ models.
Is the flat-six TR69 suitable for daily driving, or is it mainly for track use?
While the TR69 is track-capable, it is designed for spirited road use with adjustable suspension and performance-oriented electronics. It delivers strong midrange power and confident cornering, making it practical for spirited commutes and weekend drives while still offering a polished cabin for comfort.
What role does rear-biased weight distribution play in the driving dynamics of the BRZ?
The rearward weight bias sharpens turn-in and reduces understeer, allowing the engine placement to work in harmony with the chassis. This setup improves agility, makes the car feel responsive at every speed, and supports the driver-focused experience that defines the BRZ driving position.
