Background
With the humdrum shopping Impreza as its base, the Japanese engineers went full-on banzai to develop the Impreza Turbo into a street fighting machine that was at home on the track as it was a forestry rally stage.
The WRX (World Rally eXperimental) flat-four engine is turbocharged and develops around 235bhp in initial trim. Modest by today’s standards but anything but in-period, the Scooby feeds its power to the tarmac via a manual gearbox and a sophisticated four-wheel-drive system. A relatively lightweight car, it goes like stink and took the motoring world by storm. Rally win followed rally win - and the Brits wanted a piece of the action, importing both saloon and hatchback variants by the container load.
The STi (Subaru Tecnica International) version takes the basic recipe to Heston Blumenthal-type levels of sorcery via hand-assembled and tuned engines, upgraded suspension and stylistic tweaks. Much-prized by collectors and enthusiasts alike, they are the ultimate evolution of the Impreza Turbo range.
Of course, there are Impreza Turbos and there are Impreza Turbos, and while the STi is the one we all used to lust after, the 22B of March 1998 is so rare as to be almost mythical. Just 425 were built in the six months of production, with 400 being retained for the Japanese domestic market (all of which were sold on the day the order books were opened…), leaving just a handful for sale elsewhere.
Built to commemorate Subaru’s 40th anniversary and its third consecutive manufacturer’s title in the World Rally Championship, the car was rebuilt from the ground-up with a host of new parts.
Parts such as the 2.2-litre engine. Hand-built, it developed (officially, but you know what the Japanese are like for understatement…) 267bhp and 265lb/ft of torque. A twin-plate ceramic metal clutch was used, helping those figures manifest themselves as a 0-62mph time of around 4.7 seconds and a standing quarter in 13.5 seconds.
The fancy-pants transmission also features an adjustable centre-differential, which can send as much as 65% of the engine’s torque to the rear wheels, shuffling more to the front automatically should it detect slippage. With it locked, the torque split is 50:50, so ideal for snow.
The suspension is courtesy of Bilstein, and features forged aluminium lower links, rose-jointed transverse links, and Eibach springs. Four-pot Brembo front calipers help it stop more smartly than any other Impreza and they fit underneath bigger, 17-inch BBS alloy wheels.
Finished in a unique shade of blue, the seam-welded bodyshell also features widebody arches inspired by the Peter Stevens’ WRC car. The bonnet, front and rear wings, front bumper and huge rear wing are also unique.
