In the pantheon of automotive legends, few cars command the reverence, mystique, and sheer financial value quite like the Subaru Impreza WRX 22B STi. Born from the golden age of rally and forged in the fires of competition, this limited-edition masterpiece stands as not only one of the most iconic Subarus ever made but also, unequivocally, the most expensive WRX to date. More than just a car, the 22B is a tangible piece of motorsport history, a homologation special that perfectly encapsulates Subaru’s rally dominance of the late 1990s.

The Legend is Born: Genesis of the 22B STi

The late 1990s were a glorious era for Subaru in the World Rally Championship (WRC). With legendary drivers like Colin McRae and Richard Burns behind the wheel, the Impreza WRC car clinched three consecutive WRC manufacturers’ titles from 1995 to 1997. To celebrate this unprecedented success and Subaru’s 40th anniversary, the company decided to create a road-going tribute that was as close to a rally car as legally possible: the Impreza WRX 22B STi. Launched in March 1998, its primary purpose was to homologate components for Subaru’s new WRC car, ensuring that the technology on the track could trace its roots to a production model.

Unpacking the 22B: What Made it Special?

The 22B wasn’t just another Impreza; it was a meticulously engineered machine built for a singular purpose: performance. Every aspect of its design and construction screamed rally pedigree and exclusivity.

Exterior Design and Aggression

Visually, the 22B was an unmistakable statement of intent. It immediately distinguished itself from standard Imprezas with its significantly wider body, mimicking the WRC car’s aggressive stance. This wasn’t merely cosmetic; the wider fenders accommodated a wider track and larger wheels. Key exterior features included:

  • Widebody Flares: Dramatically flared wheel arches extending 80mm wider than a standard WRX.
  • Unique Front Bumper and Hood: Featuring a larger air intake and vents for improved cooling.
  • Adjustable Rear Wing: A massive, two-tier adjustable rear spoiler that was a direct nod to the rally machine.
  • Gold BBS Forged Wheels: 17-inch, lightweight gold BBS wheels (a signature Impreza STi color) wrapped in Pirelli P Zero tires.
  • Sonic Blue Paint: The iconic rally blue paint scheme that became synonymous with Subaru’s WRC success.

Heart of the Beast: Engine and Performance

The true heart of the 22B lay beneath its hood, where a unique powertrain resided. Unlike the standard 2.0-liter EJ20 engine found in other WRXs, the 22B featured a stroked 2.2-liter turbocharged flat-four engine, designated EJ22G.

  • EJ22G Engine: This bespoke engine boasted forged pistons and a larger bore and stroke, resulting in a 2212cc displacement.
  • Power Output: Officially rated at 280 PS (276 hp), adhering to the Japanese “gentleman’s agreement” on power limits. However, dyno tests often revealed figures closer to 300-310 hp, thanks to its larger turbocharger and improved intercooler.
  • Torque: A substantial 268 lb-ft (363 Nm) delivered low down in the rev range, providing explosive acceleration.
  • Unique Sound: The larger engine and specific exhaust manifold gave the 22B a distinct, aggressive burble that enthusiasts instantly recognize.
  • Performance Figures: Capable of 0-60 mph in under 5 seconds, and a top speed electronically limited to 155 mph.

Chassis and Handling

To match its formidable engine, the 22B received a comprehensive overhaul of its chassis and suspension components, transforming it into a razor-sharp handling machine.

  • Bilstein Suspension: Inverted Bilstein dampers with Eibach springs provided a stiffer, more controlled ride, capable of handling aggressive driving.
  • Wider Track: The wider body allowed for a wider track, enhancing stability and grip.
  • Closer Ratio Gearbox: A strengthened, closer-ratio 5-speed manual transmission optimized for rapid acceleration and rally-style driving.
  • Driver-Controlled Center Differential (DCCD): This advanced system allowed the driver to manually adjust the torque split between the front and rear axles, tailoring the car’s handling characteristics to different conditions.
  • Improved Braking: Larger, 4-pot front and 2-pot rear brake calipers provided superior stopping power.

Interior and Exclusivity

The interior of the 22B maintained a functional, driver-focused aesthetic, albeit with exclusive touches that underscored its limited-edition status.

  • Blue STi Seats: Unique blue and black suede-trimmed STi seats offered excellent support.
  • Red Stitching: Subtle red stitching accents throughout the cabin.
  • Numbered Plaque: Each car featured a numbered plaque on the center console, indicating its place in the limited production run.
  • STi Gauges: Specific STi instrumentation.

The Price Tag: Why So Expensive?

The Subaru Impreza WRX 22B STi has shattered auction records and consistently fetches prices well into the six figures, making it the most expensive WRX by a significant margin. Several factors contribute to its stratospheric value:

  • Extreme Rarity: Only 400 units were produced for the Japanese domestic market (JDM), selling out within hours. An additional 24 cars were made for overseas markets (16 for the UK, 5 for Australia, and 3 prototypes), bringing the total to just 424. This scarcity alone drives immense demand.
  • WRC Pedigree: It is a direct descendant of a championship-winning rally car, built during Subaru’s most dominant period in motorsport. This direct link to rally glory resonates deeply with enthusiasts and collectors.
  • Uncompromised Performance: The 22B was not just a cosmetic special; it was a genuinely high-performance machine, offering a raw, analog driving experience that is increasingly rare in modern cars.
  • Iconic Status: Its aggressive looks, distinctive sound, and rally heritage have cemented its place as an automotive icon. It represents the pinnacle of the classic Impreza generation.
  • Collector’s Item and Investment: The combination of rarity, performance, and historical significance has made the 22B a highly sought-after collector’s item, with its value appreciating steadily over the years, often outperforming traditional investments.
  • “Last of the Breed”: For many, it represents the ultimate iteration of the “classic” Impreza, before subsequent generations grew larger and heavier.

Driving the Dream: The 22B Experience

Driving a 22B is often described as an intensely visceral and engaging experience. The wider chassis and stiffer suspension provide immense grip and stability, while the precise steering rack offers direct feedback. The EJ22G engine pulls ferociously from low RPMs, delivering a surge of acceleration accompanied by its distinctive, throaty growl. It’s a car that demands attention and rewards skilled drivers, providing an analog connection to the road that few modern machines can replicate. It feels raw, purposeful, and utterly dedicated to performance.

Legacy and Impact

The Subaru Impreza WRX 22B STi remains a towering achievement in automotive engineering and a testament to Subaru’s rally heritage. Its influence can be seen in subsequent generations of the WRX and STi, which continued to emphasize all-wheel drive performance and rally-inspired styling. Beyond its direct descendants, the 22B solidified the Impreza’s legendary status and helped cultivate a passionate global following for Subaru. It stands as a benchmark for homologation specials and a timeless symbol of an era when rally cars ruled the roads, both on and off the stages.

Conclusion

The Subaru Impreza WRX 22B STi is far more than just “the most expensive WRX made.” It is a meticulously crafted machine, a direct embodiment of Subaru’s golden era in rally, and a testament to uncompromising performance. Its scarcity, legendary status, and intoxicating driving experience have cemented its place as one of the most desirable and valuable Japanese performance cars ever built. For those fortunate enough to own or even experience one, the 22B offers a unique connection to a heroic period in motorsport, an enduring icon whose value only continues to climb.
