Before it became a blue-and-gold poster car, the 1998 Subaru Impreza 22B STI was STI’s answer to a very specific question: what would happen if Subaru turned its World Rally Championship identity into a road car and stopped pretending to be subtle? The answer was a wide-bodied GC coupe with a 2.2-liter turbo boxer engine, close-ratio gearbox, driver-controlled center differential, and a chassis built to make every piece of the bodywork earn its place.
It was not a homologation special in the old Group A sense. World Rally Car rules introduced for 1997 did not require a special road car to mirror the rally car. The 22B was a celebration of the 1997 Impreza World Rally Car and Subaru’s third consecutive manufacturers’ title: a limited-production expression of the rally car rather than the car that made it legal to compete. STI’s 22B history describes it as a road model recreating the look and feel of the 1997 World Rally Car.

Subaru Impreza 22B STI at a glance
| Specification | 1998 Impreza 22B-STI Version |
|---|---|
| Market | Japan-market limited-production model |
| Production | 400 units |
| Body | Two-door GC Impreza coupe with unique wide fenders and aero |
| Engine | Turbocharged 2.2-liter EJ22G flat-four |
| Displacement | 2,212 cc |
| Factory output | 280 PS at 6,000 rpm |
| Factory torque | 363 Nm at 3,200 rpm |
| Transmission | Five-speed close-ratio manual with driver-controlled center differential |
| Kerb weight | 1,270 kg |
| Wheels and tires | Gold BBS forged 17-inch wheels with 235/40R17 tires |
These are Japanese-market factory specifications. STI lists the 22B as a 400-unit model, rated at 280 PS and 363 Nm, with the 2,212 cc EJ22G engine. STI heritage specifications are the useful reference here; later reports of a higher real output are estimates rather than Subaru’s published figure.
Why the 22B was forbidden fruit in America
The 22B was launched through Subaru’s Japanese dealer network, not as a new U.S. Subaru model. That mattered. American enthusiasts saw the WRC Imprezas, knew the blue-and-gold look, and then watched the most focused road-going version remain a Japan-market special. The regular U.S.-market WRX would not arrive until 2002, followed by the WRX STI in 2004.
That gap helped turn the 22B into a symbol before most American enthusiasts had seen one in person. Its appeal was never simply that Subaru made a limited car. It was that STI put the rally-era hardware and visual language into a compact coupe that sat outside the normal U.S. product story.
The rally era that made the 22B possible
Subaru had already made the WRX name mean something by 1998. The compact Impreza became a World Rally Championship fixture in the mid-1990s, with the blue-and-yellow livery, boxer soundtrack, and wide-bodied rally cars giving the brand an identity far bigger than its road-car sales might have suggested.
The championship run behind the 22B
- 1995: Subaru won its first WRC manufacturers’ championship, while Colin McRae won the drivers’ championship in an Impreza.
- 1996: Subaru retained the manufacturers’ championship.
- 1997: The new Impreza World Rally Car won Subaru a third consecutive manufacturers’ title, the first such three-peat by a Japanese manufacturer.
STI’s own history records the 1995 driver-and-manufacturer double, the 1996 manufacturers’ title, and the 1997 three-peat. That sequence is the reason the 22B reads as a celebration with real sporting weight rather than a limited trim assembled around a paint scheme.
The 22B arrived after Subaru won its third consecutive WRC manufacturers’ championship in 1997. Subaru’s original launch material framed it as a road version inspired by the Impreza World Rally Car ‘97, while also marking Subaru’s 40th anniversary. That context explains the bodywork. The blistered fenders, aluminum hood, larger rear spoiler, and integrated-front-grille bumper were not borrowed from a regular WRX appearance package. They were the visual language of Subaru’s rally program put on a two-door road car.
The World Rally Car regulations had changed before the 22B arrived, and its 2.2-liter engine sat outside the rally rules’ 2.0-liter limit. The 22B was STI celebrating what the WRC program had become, not satisfying a production requirement for it.
More than a wide-body Version V STI
The 22B started with the GC-generation Impreza, but the engine was its defining mechanical change. STI enlarged the turbocharged flat-four to 2,212 cc and called it the EJ22 modification. Its published peak output stayed at 280 PS, the familiar Japanese-market figure of the era, but factory torque was 363 Nm at 3,200 rpm. STI described a broad high-torque range from 2,800 to 5,200 rpm.
The larger engine was not just a bigger number on a specification sheet. STI paired its broad torque range with short gearing and the compact GC footprint, creating a road car with a different emphasis from a regular 2.0-liter turbo Impreza.
The rest of the drivetrain received the same attention. STI specified a close-ratio five-speed with a driver-controlled center differential, reinforced gearbox parts, and a twin-plate clutch. The suspension used specially tuned Bilstein dampers and Eibach springs, while the wider fenders made room for 235-section tires on forged BBS wheels. The 13:1 steering ratio mattered as much as the wing: this was built to respond quickly, not merely to look like a rally replica.

Why the 22B looks the way it does
The 22B’s silhouette is the reason it is instantly recognizable even to people who cannot name an EJ engine. A regular GC Impreza is a compact, upright car. The 22B uses that small shape as a base, then stretches it with pronounced front and rear fenders, deeper bumpers, side skirts, an aluminum hood, and the high rear wing.
Those parts changed the stance, but they also supported the hardware. The wide fenders accommodated the wider tire package. The hood scoop fed the top-mount intercooler. The wing and aggressive bumpers made sense in a car designed to look and feel related to Subaru’s WRC machine.
Sonic Blue Mica and gold wheels became inseparable from the 22B, though the car’s importance is not a paint-and-wheel formula. Countless later Subarus have borrowed the colors and the visual cues. The original is memorable because the chassis, drivetrain, body, and rally moment all point in the same direction.

The mechanical idea behind the 22B
The 22B’s reputation was not built only by photographs and rarity. Its close-ratio gearbox, driver-controlled center differential, quick steering, wide tires, and compact 1,270 kg body give a clear picture of the intended experience: a focused, mechanical road car from before all-wheel-drive performance sedans became larger and more insulated.
That is why the car has remained compelling after newer WRXs became quicker, safer, and more capable in ordinary use. The 22B concentrates the parts that established Subaru’s performance identity into one unusually cohesive package.
What the 22B left behind
The 22B gave Subaru Tecnica International a template for the limited complete car: start with a familiar platform, make the changes cohesive, and build a short run with a clear purpose. STI’s later S-series cars followed that idea in their own ways, from the S201 through more recent models. They are not 22B replicas, but they follow the same useful principle: the complete car matters more than a pile of branded parts.
It also fixed a picture of Subaru performance in enthusiasts’ minds. The original U.S.-market WRX arrived four years later, and the U.S.-market WRX STI arrived in 2004. Neither was a 22B replacement, but both benefited from the rally-era credibility and engineering identity that the 22B concentrated so effectively. For the broader model split, see our Subaru WRX vs. STI guide and what STI means on a Subaru.
Today, the 22B is often reduced to an auction headline or a blue-and-gold poster car. It captured a precise moment when Subaru’s WRC success, STI’s engineering, and the compact Impreza chassis all lined up. The widebody coupe endures because every part of it still points back to that moment.
