The P1 was available in late 1999, limited to a production run of 1000. Other than the ultra rare 22B, the P1 is the only official 2-door coupe sold in the UK.
Only available in Sonic Blue, the P1 has a front splitter and rear spoiler designed by Peter Stevens, amd is fitted with smaller recessed driving lamps in place of the normal Impreza fog lights.

1998 saw the release of what many consider to be the ultimate Impreza - the 22B. Named after it 2.2ltr Boxer engine, 22B also translates to 555 in hex, Subaru's main sponsor in its rally program at that time. Lucky coincidence? The 22B has wider arches front and rear, along with a restyled front and rear bumpers to fit, and an adjustable rear wing. Mechanically, apart from the bigger displacement engine, it depends on whether you are looking at a 'type UK' model or an import, as there are differences in spec. The UK model (of which only 16 were produced) has revised gearing better suited to UK roads. In total only 400 22B's were produced, to celebrate Subaru's 40th anniversary.
