Subaru WRX STI 2024: Engine Power & Handling Review

The 2024 Subaru WRX STI arrives as a complete redesign, marking the first generation since 2014 with a brand-new engine and significantly upgraded handling dynamics. This high-performance sedan finally delivers on the promise of modern technology while maintaining the raw, engaging driving experience that enthusiasts crave. Let’s dive into what makes this generation special.

Revolutionary 2.4L Turbocharged Engine

Gone is the legendary 2.0L four-cylinder that powered previous generations. The 2024 WRX STI introduces a 2.4L turbocharged boxer engine producing an impressive 315 horsepower and 310 lb-ft of torque. This represents a significant jump from the outgoing model’s 310 hp, though the real advantage lies in the broader power delivery.

The larger displacement engine breathes better at high RPMs and provides improved mid-range acceleration. Direct fuel injection and revised turbocharger tuning ensure responsive throttle response without excessive lag. The powerplant feels more refined than its predecessor, with a distinctive boxer rumble that’s music to any enthusiast’s ears. Real-world performance translates to a 0-60 time of approximately 4.6 seconds, making it competitive with rivals like the Honda Civic Type R.

Key engine features include:

  • Improved cooling system for better sustained performance
  • Reinforced internals rated for higher boost pressures
  • Electronic boost control for consistent power delivery
  • Enhanced fuel efficiency compared to 2015-2023 models

Handling Excellence: Where the STI Truly Shines

The 2024 STI represents a complete overhaul of the suspension architecture. Subaru’s engineers developed a fresh multi-link independent rear suspension paired with a reinforced chassis that’s significantly more rigid than the previous generation. The result is handling that feels sharper, more communicative, and genuinely capable on both road and track.

The car features Subaru’s famous symmetrical all-wheel drive system, now enhanced with a more responsive center differential. This allows for better weight distribution during cornering and improved traction management in various conditions. The steering response has been tuned for precision, delivering genuine feedback through the wheel without feeling overly heavy or artificial.

At the track, the 2024 WRX STI demonstrates impressive capabilities. The chassis remains composed even during aggressive driving, and the brakes—upgraded Brembo units with better heat dissipation—provide confident stopping power lap after lap. Enthusiasts will appreciate the improved body control and minimal body roll in corners. The car finally feels like a genuine performance machine rather than a street-tuned sedan.

Suspension improvements worth noting:

  • Stiffer bushings reduce deflection under hard cornering
  • Revised damper tuning balances comfort with sportiness
  • Wider track for improved stability and tire contact
  • Available adaptive dampers provide real-time adjustment

Daily Usability Meets Performance

Despite its track-ready credentials, the 2024 WRX STI doesn’t sacrifice everyday practicality. The cabin feels more premium than before, with improved materials and a modern infotainment system. Visibility is excellent, and the driving position accommodates various body types comfortably. Rear passengers have adequate legroom, and the 11.6-cubic-foot trunk suits most road trip scenarios.

The transmission options have evolved too. The standard 6-speed manual features a revised linkage for quicker shifts, while the optional automatic transmission (new for STI) provides convenient daily driving without compromising sportiness. Real enthusiasts will stick with the manual, though the automatic performs admirably.

Fuel economy sits around 20-22 mpg combined—respectable for a turbocharged performance car. The STI now accepts regular 87-octane fuel while running on premium for maximum performance, offering flexibility that previous generations lacked.

The Verdict

The 2024 Subaru WRX STI succeeds where it matters most. The new 2.4L engine delivers meaningful performance gains without compromising reliability, while the revolutionary chassis and suspension architecture transform handling into something genuinely thrilling. This isn’t just a refresh—it’s a legitimate redesign that respects the STI nameplate while pushing it forward.

For buyers seeking a practical performance sedan that excels in real-world driving and track use, the 2024 WRX STI deserves serious consideration. It finally answers the question enthusiasts have asked for years: when will Subaru truly update this icon? The answer is now, and it’s worth the wait.
