The Subaru WRX. The very name evokes images of gravel-spitting, turbocharged exhilaration, a symphony of boxer engine growl, and a badge synonymous with rally racing prowess. For decades, this compact Japanese sedan has carved a unique niche in the automotive landscape, evolving from a homologation special into a bona fide performance icon. Its journey is a fascinating blend of motorsport DNA, practical engineering, and unwavering enthusiast devotion. This article will delve into the rich history of the Subaru WRX, tracing its evolution through its various generations, models, and trim levels, and exploring what makes it a legend.
The Impreza’s Genesis: The Foundation of a Legend (1992-2000 – First Generation)
The story of the WRX doesn’t begin with its own nameplate, but rather as a potent variant of Subaru’s compact family car, the Impreza. Born out of the need for Subaru to homologate a vehicle for Group A World Rally Championship (WRC) racing, the original Impreza WRX (World Rally eXperimental) burst onto the scene in 1992.
The first generation Impreza WRX was a revelation. It featured a turbocharged 2.0-liter EJ20 flat-four engine, delivering a potent 237 horsepower in its initial iteration. Crucially, it also boasted Subaru’s signature symmetrical all-wheel-drive system, a cornerstone of its rally dominance. The aggressive styling, featuring flared fenders and a prominent rear wing, immediately signaled its performance intent.
Within this first generation, several key models and trims emerged:
Impreza WRX (GC/GF/GM chassis): The standard WRX model, the workhorse of the lineup.
Impreza WRX STI (GC/GF/GM chassis): Introduced in 1994, the STI (Subaru Tecnica International) variant represented the pinnacle of WRX performance. It featured engine enhancements (higher boost, revised ECU, forged internals), stiffer suspension, stronger brakes, and often a more aggressive aerodynamic package. Early STIs were identifiable by their blue paint, gold wheels, and STI badging. Power increased significantly over the generation, reaching around 270 horsepower in later models.
Specific STI sub-models like the WRX STI Type RA (Record Attempt) were produced in limited numbers for homologation purposes and featured weight-saving measures and further performance tuning. The WRX STI V-Limited was another special edition, often featuring unique color schemes.
Impreza WRX Limited/Sports Sedan: These trims offered a slightly more refined interior and a less aggressive aesthetic, but still retained the turbocharged engine and AWD.
Impreza WRX Wagon (GF chassis): For those who desired performance with a practical cargo space, the WRX wagon offered a compelling option.
The first generation laid the groundwork, establishing the WRX’s reputation for raw performance, exceptional handling, and its undeniable connection to the world of rallying. Its ruggedness and tunable nature also fostered a dedicated aftermarket and enthusiast community.

Refinement and Expansion: Embracing a Global Audience (2000-2007 – Second Generation)
The second generation Impreza, known internally as the “Bugeye” (2000-2002) and later the “Blobeye” (2002-2005) and “Hawkeye” (2005-2007), saw Subaru further refine the WRX formula. While the core recipe of a turbocharged boxer engine and AWD remained, the styling underwent significant changes, with the initial “Bugeye” design being particularly controversial yet iconic.
Underneath the skin, Subaru continued to develop the EJ20 and later the EJ25 engines, increasing power and responsiveness. The chassis was also stiffened, and suspension geometry was tweaked for even better handling.
Key models and trims for the second generation include:
Impreza WRX (GDA/GGB chassis): The sedan continued to be the primary WRX offering. Power output saw a steady increase, with later models reaching around 227 horsepower in US spec.
Impreza WRX STI (GDB chassis): The STI remained the ultimate expression of the WRX, with significantly more power and a more track-focused setup. In the US, the EJ257 engine became standard, producing around 300 horsepower. The STI models were distinguishable by their more aggressive body kits, larger rear wings, and often Brembo brakes.
Special STI editions included:
WRX STI Prodrive: Developed with WRC partner Prodrive, these models featured further performance enhancements and unique styling.
WRX STI S203/S204: Limited-production, highly exclusive STI variants with even greater power and meticulously tuned chassis.
WRX STI Wagon (GG chassis): Continuing the practicality of the previous generation, the
WRX wagon was also available with STI performance.
Impreza 2.5 RS (US Market): While not a WRX, the 2.5 RS acted as a gateway for many Americans to experience Subaru’s sporty ethos. It featured the EJ25 engine without a turbo but boasted the sporty styling and AWD system, offering a taste of the WRX’s appeal.
The second generation saw the WRX become more accessible globally, with Subaru actively marketing it in various regions. It also cemented its status as a tuner’s dream, with a readily available aftermarket supporting further customization and performance upgrades.
The Birth of the Standalone WRX: A New Identity (2007-2014 – Third Generation)
A significant shift occurred with the third generation Impreza (GE/GH/GR/GV chassis) launched in 2007. Subaru decided to differentiate the WRX and WRX STI more distinctly from the standard Impreza. While still based on the Impreza chassis, the WRX and STI models received more aggressive styling and a wider track, setting them apart visually. This generation also saw the introduction of the “widebody” styling elements that would become a signature of the STI.
This generation also brought about structural changes and a continued focus on chassis rigidity, further enhancing the WRX’s already impressive handling characteristics.
Key models and trims for the third generation:
Impreza WRX (GH8/GE8 chassis): The WRX sedan received a turbocharged 2.5-liter EJ255 engine, producing around 265 horsepower. It featured a sportier suspension and a more aggressive body kit than the standard Impreza.
Impreza WRX STI (GRB/GVB chassis): The STI received the more powerful EJ257 engine, now producing around 305 horsepower. It also received a wider body, a more pronounced rear wing, performance brakes, and a limited-slip center differential for superior traction.
WRX STI hatchback (GR chassis): A notable addition was the WRX STI hatchback, offering a more practical alternative while retaining the full performance of the sedan.
WRX STI Special Editions: Throughout this generation, Subaru continued to release limited-edition STI models, often with unique paint schemes, performance upgrades, and badging, such as the WRX STI Hatchback Special Edition and various motorsport-inspired variants.
The third generation marked a turning point, with the WRX and STI beginning to shed their Impreza roots in terms of public perception and marketing, solidifying their individual identities as distinct performance vehicles.
The Era of the Standalone Model: Evolution and Refinement (2015-Present – Fourth Generation & Beyond)
