Subaru Impreza WRX STI
The Subaru Impreza WRX STI is a high performance model of the Subaru Impreza compact car line, manufactured by Japanese automaker Subaru.
In 1988, Subaru created Subaru Tecnica International (STi) as its motorsport division to develop and compete in the FIA World Rally Championship and other motorsports activities. Following the introduction of the first generation Impreza in November 1992 and the following year's debut of the Group A rally car into the WRC, an 'STi version' was made commercially available in January 1994 as a homologation model under FIA regulations. Thereafter, subsequent evolutions dubbed STi Version or simply STI were manufactured and sold alongside the Impreza model lineup initially in Japan only and later in selected world markets. As the STi or STI model was typically the highest spec of the Impreza, it has become popular with performance enthusiasts, tuners and amateur racers in many motorsports disciplines especially rallying and circuit driving.
Subaru has released many different models and versions including special limited editions of the WRX STI. However many of these versions were and are only available in the Japanese Domestic Market. Although the concept behind the STI model is taking a base model such as the Impreza or Legacy and further developing it for high performance, STI models fall mainly into 2 categories. The first is a fully developed and tested model with the purpose of homologating it for motorsports which is sold as a street legal road car. The second is a complete car pre-fitted from the factory with parts that are available from the STI catalogue and marketed as a 'Tuned by STI' model. Spin-off models with mainly cosmetic additions or alterations are also marketed usually in limited quantities.
The first generation STI tuned road going cars were only developed and sold in the Japanese market. Although marketed by numerical version indicators up to 'Version VI' in the catalogue, there were in reality more than 20 different possible types of Impreza STI cars for sale. Many of these were in different body styles and some designed as a base for motorsports use. Others, such as the 22B were special limited versions but had different specifications. Visually it is hard to tell the difference between versions or the non-STI Impreza WRX. Unlike its rival car the Mitsubishi Lancer Evolution, which sported a quite distinct exterior design difference, the Impreza WRX and WRX STi version had mainly mechanical modifications. One way to identify the version is through the VIN plate on the chassis. Sedan and Coupé STi model codes are named GC8, (USDM coupés have a separate chassis code of "GM") and Station Wagons are named GF8, followed by a letter from A to G. A GC chassis version of the RS was released for the USDM in 2001. To tell the difference between a JDM Sedan and Coupe chassis from the applied model code only, a sedan will have the fifth digit as a 4, representing 4 doors, and a coupé will have a 2, representing 2 doors.
The first STi was known simply as WRX STi (there was no "version" moniker added to the name until the version II). 100 Imprezas per month were produced starting from February 1994. In March, production was stabilized to 100 STis per month. It had 250 PS (184 kW; 247 bhp) at 6,500 rpm and 31.5 kgf·m (309 N·m, 228 ft·lbs) at 3,500 rpm and weighed 1230 kg (2,710 lb). Before the STi, the highest trimline of the Impreza was the WRX and the WRX RA, first manufactured in November 1992. This version of the STi was the only version where the standard cars were taken at the end of the assembly line and replaced by STi parts. After this version, the standard STi was built alongside the WRX on the production lines.
The WRX STi Type RA (marketing has made usage of the RA acronym in various ways; Record Attempt is the current usage. "R = Racing, A = Group A, FIA the racing class the WRC Impreza competes in" has also been confirmed by Subaru of Japan; the correspondence can be seen on the discussion board for this article) version produced 275 PS (202 kW; 271 bhp) and 32.5 kgf·m (319 N·m, 235 ft·lbs) of torque. This version of the WRX STi was a stripped out car that had no sound-deadening, radio or air conditioning. It came sparsely equipped as it was to be sold to racing teams that would remove the cheap parts and fit racing parts. This version of the WRX came with a Driver Controlled Center Differential (DCCD). This device was an electromechanical differential that could lock the differential. The DCCD would be beneficial to people who used it in various rally conditions.
The regular STi's engine output stood at 275 PS (202 kW; 271 bhp) and 32.5 kgf·m (319 N·m, 235 ft·lbs) of torque. This was the year that STi started painting the intake manifold red. The car weighed 1,240 kg (2,734 lb) and had gold wheels like those on the World Rally Championship Impreza.
The V-limited STi edition was produced. It was a limited edition that was often used to celebrate a Manufacturer or Driver title award to Subaru's World Rally Team. The interior is colored blue on the seat inserts and carpeting. The WRX Type RA STi received a radio and air conditioning in the V-limited form. 1,000 WRX STi Version 2 V-limited were produced. 555 (the cigarette brand that was the premier sponsor of the Subaru World Rally Team and became synonymous with the Impreza WRC livery) WRX Type RA STi Version 2 V-limited were produced.
