The Subaru Impreza 22B was produced to commemorate both the 3rd consecutive manufacturer's title for Subaru in the FIA World Rally Championship and Subaru's 40th anniversary. A widebody, 2-door Impreza, the 22B STi came with the EJ22 engine as opposed to the regular EJ20 engine increased from 1994 cc to 2212 cc.

The 22B was painted the Subaru Rally Team blue and had flared widebody fenders taken from the Peter Stevens designed WRC car, widening the 22B by 80 mm (3.15 inches). The chassis for the 22B was from a WRX Type R which was pulled from the assembly line, and had 22B STi fenders added. The transmission ratios on the 22B are the same as the standard WRX Type R of the day, but the gears were shot-peened for extra reliability. The 22B also has a unique hood, a WRC-inspired front bumper and a unique adjustable rear wing. The clutch was upgraded to a sintered twin clutch with a ceramic disk.

Where the name 22B originated has often been debated. Most people would say that the 22 referred to the 2.2 liter engine and the B was for the Bilstein suspension. Others say that 22B was meant to represent the sponsorship of the Subaru WRC cars (555) which is a tobacco company, as 22B is a hexadecimal representation of the decimal number, 555.

Subaru has proven to be rather superstitious with the 22B STi that was supposed to be #13 was never given the plaque. Subaru of America imported #13 to be used as a press car. Three 22B STis were given the #000 plaque, 2 of the cars went to Colin McRae and Nicky Grist driver and co driver for Subaru at the time,
with the third 22B used by Subaru Japan as their press car. 400 were made in total.

The UK had there own 22Bs imported, named the 22B Type UK 16 were modified by Prodrive, adding longer gear ratios, UK spec lights and an official 3 year warranty. Subaru UK had to wait until 1999 to register the 22B Type UKs under the VCA's Single Vehicle Approval scheme because 50 22Bs had already been imported privately into the UK.
