2027 Subaru WRX STI: Aggressive Hatchback, Tuned FA24 Power & Advanced AWD

The Subaru WRX STI is back. After years of speculation, fan campaigns, and an official pause on the halo performance model following the 2021 discontinuation, Subaru has confirmed development of a new 2027 WRX STI — and it arrives as a proper five-door hatchback with a six-speed manual transmission.

This isn’t a mild refresh or badge-engineered WRX. Early reports, patent filings, and official teases point to a widebody, rally-bred hot hatch that blends modern design aggression with the raw, engaging character that made the STI legendary. Powered by a tuned version of the FA24 turbo boxer-four, it delivers meaningful power increases, serious chassis upgrades, and the return of enthusiast-focused hardware like a heavy-duty TY85 manual with DCCD-style control.

Here’s everything we know — and the deeper insights into design, powertrain, AWD, interior tech, market positioning, rivals, and meaningful upgrades that set the 2027 STI apart.

Why Subaru Revived the STI for 2027

Subaru previously stated that no next-generation internal-combustion STI would be built on the current WRX platform due to electrification priorities. Yet enthusiast demand remained sky-high. Limited-run models like the 2026 WRX STI Sport in Japan sold out instantly (over 9,000 applications for just 600 cars).

In June 2026, Subaru’s executive vice president and CTO Tetsuro Fujinuki, speaking at Fuji Speedway, announced three new manual-transmission models for 2027 developed by the newly formed Sports Vehicle Planning Office. The lineup includes a manual WRX, updated BRZ, and — most excitingly — a five-door hatchback that evolves into the performance-focused WRX STI.

This office focuses on trickle-down motorsport technology for accessible, enjoyable cars. The 2027 WRX STI is the flagship expression of that philosophy: a driver’s car first, with rally DNA intact in an era of hybrids and EVs.

Exterior Design- Rally Style

The 2027 Subaru WRX STI hatchback draws heavily from the Performance-B STI Concept (and earlier STI-B show car). Leaked patent images and renders show a dramatically wider stance than the current sedan WRX, with bulging fenders, a functional hood scoop, aggressive front splitter, black aero accents, and a massive fixed rear wing.

  • Widebody architecture — Adds visual muscle and allows for wider track and bigger tires without compromising the boxer engine’s low center of gravity.
  • Lighting & fascia — Sharp, modern LED headlights and taillights with STI-specific signatures. The front end features a larger, more purposeful grille and splitter for better cooling and downforce.
  • Rear end — Prominent diffuser, center-exit exhaust (or quad tips in some configurations), and that iconic giant wing. Functional vents and aerodynamic detailing suggest serious high-speed stability.
  • Colors & details — World Rally Blue remains the hero shade, with red STI accents, black mirrors and trim, and forged BBS-style wheels (likely 19-inch).

What makes it unique: Unlike pure show cars, the production version appears to retain functional aero elements (not just decorative). The hatchback proportions improve practicality dramatically over the old sedan STI while keeping the low, planted rally-car stance. Expect subtle active or adjustable aero elements in higher trims, and easy wing-delete options for daily drivers who want cleaner looks.

This is the most aggressive factory Subaru design in years — modern yet instantly recognizable as an STI.

Powertrain: Tuned FA24 Turbo Boxer with Real Upgrades

The 2027 Subaru WRX STI marks the first use of the FA24 2.4-liter turbocharged boxer-four in an STI-badged model. Base WRX output sits at 271 hp and 258 lb-ft. The STI version gets meaningful tuning:

  • Expected output: Approximately 300 metric horsepower (roughly 296 hp) and 295 lb-ft of torque.
  • Key upgrades: Larger intercooler, revised turbocharger, optimized intake/exhaust, and new ECU mapping. These changes improve mid-range response and overall character while meeting stricter emissions standards.
  • Transmission: The legendary TY85 6-speed manual returns — the same heavy-duty unit from previous-generation STIs. It’s being modernized with higher torque capacity and potential DCCD (Driver Controlled Center Differential) integration or advanced electronic center-diff control for track durability.
  • No hybrid for now: While Subaru explores electrification elsewhere (Forester Hybrid, upcoming EVs), the 2027 Subaru WRX STI stays pure ICE. This preserves the raw throttle response, boxer exhaust note, and mechanical engagement enthusiasts crave. A hybrid STI may come later as a parallel offering.

Performance expectations: 0-60 mph in the low-to-mid 5-second range (quicker than the current WRX’s 5.5–5.9 seconds). The power-to-weight ratio (around 3,527 lbs / ~1,600 kg) should deliver strong in-gear punch. Top speed will likely be electronically limited in some markets.

Subaru isn’t chasing headline horsepower numbers. Instead, engineers appear focused on transient response, torque delivery, and that signature boxer character. The new turbo and intercooler should reduce lag while maintaining the linear, rally-car pull that defines an STI. Combined with the stiffer chassis and advanced AWD, this creates a car that feels faster on real roads than the spec sheet suggests.

Symmetrical AWD & Chassis

Subaru’s symmetrical all-wheel drive remains the model’s greatest differentiator. For 2027, expect:

  • Permanent Symmetrical AWD with a sophisticated center differential (revived or enhanced DCCD-style electronic control).
  • Possible torque-sensing mechanical limited-slip differentials front and/or rear — classic STI hardware modernized.
  • STI-specific suspension tuning with adaptive dampers (building on WRX GT/tS tech) for sharper turn-in, better body control, and rally-inspired compliance over rough surfaces.
  • Larger Brembo brakes (6-piston front calipers confirmed in concept imagery) with bigger rotors.
  • 19-inch forged wheels wrapped in high-performance tires (Bridgestone Potenza or equivalent).

In an era where many rivals are FWD or use less sophisticated AWD, the STI’s system provides superior traction in rain, snow, gravel, or track conditions. The electronic center diff allows drivers to adjust torque split (or it adapts proactively), giving a true “rally mode” feel. The hatchback’s weight distribution and lower polar moment of inertia should enhance agility compared to the sedan.

This is where the Sports Vehicle Planning Office’s motorsport influence shines — bringing Super Taikyu racing learnings into a production car.

Interior, Tech & Cabin Experience

The cabin stays driver-focused. Expect:

  • Supportive sport bucket seats with prominent bolstering, STI badging or red stitching, and possibly suede or Alcantara inserts.
  • Digital instrument cluster with performance-oriented displays (boost, torque split, lap timer?).
  • Large central touchscreen with wireless Apple CarPlay and Android Auto, plus Subaru’s latest Starlink connectivity.
  • Flat-bottom steering wheel, aluminum pedals, and STI-specific drive mode selector (SI-Drive evolution with new modes tuned by the performance office).
  • Advanced EyeSight safety suite that doesn’t overly intrude on enthusiastic driving, plus new driver aids like performance-oriented stability control with multiple defeat levels.

The interior will feel more special than a regular WRX without becoming a luxury lounge. Materials will balance durability for track use with everyday comfort. The hatchback layout adds genuine versatility — fold the rear seats and you have serious cargo space for track gear, weekend adventures, or even light off-road duties. This practicality is a massive upgrade over previous STIs and many rivals.

Market Position, Pricing & Rivals

The 2027 WRX STI slots above the regular WRX as Subaru’s performance flagship. In Japan, expect pricing around 4.0–5.0 million Yen (roughly $26,500–$33,000 USD before options). U.S. arrival is unconfirmed but highly anticipated — if it comes, realistic pricing would land in the $45,000–$55,000 range depending on equipment.

Main rivals:

  • Toyota GR Corolla — Closest spiritual competitor (AWD hot hatch, manual). STI offers superior all-weather traction and boxer character; GR Corolla may have slight power edge and circuit focus.
  • Honda Civic Type R — Sharper on smooth pavement and legendary shifter, but FWD limits it in poor conditions compared to STI’s Symmetrical AWD.
  • Volkswagen Golf R — Refined AWD and DSG option, but less raw and rally-focused.
  • Hyundai Elantra N / Acura Integra Type S — Excellent value and fun, but again FWD.

The STI’s unique selling points remain its combination of turbo boxer engine, true symmetrical AWD with advanced diff control, manual transmission purity, and hatchback practicality — plus the intangible “STI badge” heritage.
