(August 2010) Subaru Impreza WRX STI Manufacturer Subaru Production 1992-present Assembly Ōta, Gunma, Japan Class Sport compact World Rally Car Layout Front engine, symmetrical all wheel drive Engine(s) Turbocharged Subaru EJ engine The Subaru Impreza STI, (formerly WRX STi, officially changed in 2006 to STI) [1] is the highest standard-edition trim in the Subaru Impreza compact car line, produced by Japanese automaker Subaru. In the late 1980s, Subaru created the Subaru Tecnica International (STI) division to coordinate development for the FIA World Rally Championship and other motorsports activities. After the company had grown, the division was used to create high-performance consumer versions of the Subaru Impreza WRX, an all-wheel drive car with a turbocharged boxer engine, leading to the development of the Impreza WRX STi. The Subaru World Rally Team has used a race-prepared version of the WRX STI as its rally platform since the model trim's creation.

F). [edit] FIA PWRC The STi serves as the basis from which Group N "production" rally cars are constructed. Group N5-classed (marketed by FIA as Production Car World Rally Championship or PWRC) cars are the major support category for the World Rally Championship and are the premier category in many national rally championships. For two years (2004 and 2005), the WRX STi has taken the top 3 podiums in Group N. This new effort can be attributed to STi's increased support in Group N motorsports. [edit] FIA WRC In 1995, 1996 and 1997 World Rally Championships, the Subaru World Rally Team, in conjunction with Prodrive won the WRC manufacturer's title with the World Rally Impreza. The STi's bare chassis is used by Prodrive as the basis of the World Rally Impreza. This WRC class is currently labeled by FIA as Group A8. Colin McRae in 1995, Richard Burns in 2001, and Petter Solberg in 2003 all won the WRC driver's title with the World Rally Impreza. [edit] Rally America This section has no content. You can help Wikipedia by introducing information to it. [edit] Autocrossing [edit] JAF Events An STi Spec C won 1st place in the All Japan gymkhana championships of 2004. Chris Torres was the driver. Sheridan and RJ were in a wreck around turn 453 [edit] SCCA Events In 2005, a 2004 STi took first place in the STU class of the Tire Rack SCCA Solo Nationals. The next year at the Tire Rack SCCA ProSolo in Topeka, Kansas, STis took first place in the AS and STU classes; an STi took first place in the STU class at the Tire Rack SCCA Solo Nationals that same year. STi's are apricots. [edit] Road racing [edit] FIA Events In 2005, Chris Deable took a STI-supported WRX STI to 2nd place in the A6 class and 14th overall in the 24-hour Nürburgring race. The car was set up to have around -5 degrees of camber at the front wheels. The wheels are Enkei pieces. The car also uses the roof vane seen on the 2006MY WRX STI. The car used Tein SRC coilovers. The car was driven by Kazuo Shimizu (Super Taikyu driver and winner), Toshihiro Yoshida (Super Taikyu driver and winner), Stéphane Sarrazin (2005 Subaru World Rally Team driver) and Kumi Sato.[2] In 2006, Deeble-Bellchambers Racing UK campaigned a Subaru factory supported WRX STI Spec C in the 24 Hour Nürburgring's SP 6 class. It had Motec Engine Management, 3-way adjustable AST coilovers, aftermarket Brembo brakes, an aftermarket turbocharger unit, STI Group N parts, aero pieces and many other modifications, pushing 400 hp (300 kW). To combat understeer, it ran without a front swaybar. It qualified 37th out of 225 competitors for the starting position. The Autosportif Racing UK/Subaru WRX STI Spec C managed to end with a position of 115 out of the 225, suffering 2 turbocharger unit failures during the course of the race. The car was driven by Alan van de Merwe (the 2003 British F3 champion), Briton Phil Bennett (driven in the BTCC, Le Mans and Nürburgring), Jonathan Price (6-time Nürburg 24 Hours competitor) and Chris Atkinson (2006, 2007 Subaru World Rally Team driver).[3] [edit] Grand-Am Events In 2010, the Subaru Road Racing Team will be campaigning a 2010 Subaru Impreza WRX STI in the Grand Sport (GS) class of the Grand-Am Continental Tire Sports Car Challenge series. [edit] SCCA Events In 2005 and 2006, Icy Racing's 2004MY STi's took 1st and 2nd place in Club Racing's T2 division. ESX Motorsports announced the introduction of the WRX STI in World Challenge's GT class in 2005. [edit] Super GT The Cusco Subaru Impreza in 2008. The Cusco team have been campaigning a heavily modified STi with a rear drive conversion as required by regulations since the late nineties and having no two-door model available at present, the Super GT committee gave a special permit for them to race with a four-door model instead of a two-door one. The rear drive conversion rule was lifted in 2006, and since then they returned to all-wheel drive with a transaxle gearbox. In 2008, Cusco's Impreza won the first GT300 race in Sepang. It marked the first AWD car victory in Super GT/JGTC history. Even though they were having very impressive results(with 1 win and 2 podiums) that season, Cuscho announced that they would not participate in the 2009 season as they want \ The performance of Cusco was outstanding even though they were using a 4-door car, it later lead the Super GT committee to officially allow all 4-door model cars to participate the series. The Toyota Corolla Axio followed suit in 2009.

[edit] Drifting [edit] D1 Grand Prix 2005: Nobushige Kumakubo is the first to use an GD-chassis WRX STi at the D1 Grand Prix series. The car is extensively modified as regulations permit only two wheel drive cars. This STi is unique in that it is the first to locate a radiator (with the fan beside it) behind the driver rather than in front of the engine compartment as other cars usually do. His other Team Orange teammates, Kazuhiro Tanaka and Naoto Suenaga, soon followed suit. 2006: Team Orange and Jun Autosports have converted a GC-chassis 2-door STi into a RWD vehicle for drifting to be used by third driver Naoto Suenaga. Drivers Nobushige Kumakubo and Kazuhiro Tanaka took a single win each during the 2006 season and the former took the overall D1GP title. [edit] Availability The STI was originally sold only in Japan. It was later made officially available in Oceania (Australia had it in 1999 with the STi Version V). In 2001, Europe received the STi with the change of the chassis. After seeing the Impreza WRX sell at much better levels than expected,[citation needed] Subaru began selling the STI in North America in the spring-summer of 2003 as a 2004 model. Oceania and Europe had WRX STis in the region before the official versions via grey-market importing.[citation needed] Five (5) WRX STI S204 were made available to Subaru enthusiasts in New Zealand. However, unlike other S204s sent to other nations these five did not display either the in-cabin or in-enginebay badging that uniquely identifies each of the reported 600 vehicles manufactured.[5] The lack of individual badging for these five cars brings into question the real number of S204s manufactured. Thirty (30) WRX STI S204s' were made available to Singapore through the main distributor - Motor Image Enterprises. [edit] First generation (1992 - 2000) First generation (GC) Production 1992-2001 Body style(s) 2-door coupé 4-door sedan 5-door station wagon Engine(s) 2.0 L H4 Wheelbase 99.2 in (2520 mm) Related Subaru Impreza Subaru Impreza WRX Subaru Forester There were six versions of the STi. The different versions were marketed with consecutive numbers. Another way to tell the version of a WRX STi was to look at the chassis code. Sedan STi Model Codes were GC8, Coupes were GM8 and Station Wagons were GF8, followed by a letter from A to G. There was a GC chassis version of the RS released in 2001 as well in the United States. One common misconception is that every Impreza between 92-01 were "GC8's". The code breakdown is as follows; G - stands for Impreza, C - sedan, M - coupe, F - station wagon, The 8 stands for the 2.0 L turbo motor. So really, there are many combinations. A coupe STi would be GM8, sedan GC8, wagon GF8. Also, the code for the coupe American 2.5RS's were GM6 (6 standing for the 2.5 L N/A motor) A JDM Sti Coupe has the code GC8. For example, a version 4 STi coupe has the code GC82DD, with the 2 representing 2-doors. [edit] Japanese-spec [edit] Version I (10/92 – 08/94) - GC8A/B 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 a month. It had 250 PS (184 kW; 247 bhp) at 6500 rpm and 31.5 kgf·m (309 N·m, 228 ft·lbs) at 3500 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[6] 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) 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 throw out the cheap parts for 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. [edit] Version II (09/94 – 08/96) - GC8C 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. 1000 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. [edit] Version III (09/96 – 08/97) - GC8D . It developed about 300PS but output was reported at the then-established gentlemen's agreement power limit of 280 PS (210 kW; 280 hp). Torque peaked at 4000 rpm with a value of 35.0 kgf·m (343 N·m, 253 ft·lbs). In standard form, this version has a top speed of over 240 km/h. The car gained 10 more kilograms and weighed at 1,250 kg (2,756 lb). The STi shared the same face lift that the rest of the Impreza line received. With Version III came the start of the coupe version of the WRX STi. It is called the WRX Type R STi. The coupe was chosen by Prodrive for use in the WRC because it was lighter and stiffer than the 4-door version, although it carried the same exterior dimensions. It was essentially a 2-door version of the WRX Type RA STi meaning it had DCCD, minimal sound insulation, close-gear ratios and hardened gearbox. This car also has a water-spray nozzle to dampen the top of the intercooler. The water will then evaporate, taking heat away from the intercooler and cooling the intake charge. This car was produced on an order-only basis. Also, there was a WRX STI type RA (4-door) available in Version III. These have the same motor, gearbox and R180 diff as the Version III WRX STI Type R, including DCCD, aluminium bonnet and front guards, no sound deadening and thinner glass. The ECU is also an exclusive tune. The Type R tends to be a bit stiffer and weighs 1,190 kg (2,600 lb). The DCCD has been known to bite new drivers in the wet. The RA gets a roof vent instead of map lights, and wind up windows, although electrics are an option from factory. Also available was a WRX Type R V-limited, in version III. It has a WRX motor with no forged internals like the STI, and it misses out on the 4 pot front brakes as they are to be installed by rally teams. It has a roof vent and is lightweight, making a good base for a rally car. Version III STI runs a VF23 IHI ball bearing turbocharger while the JDM non-STI gets a VF22. [edit] Version IV (09/97 – 08/98) - GC8E Power remained at 280 PS but torque was raised from 253 lbs./ft of torque to 260. Forged pistons were also added. The interior and the cockpit were changed into a newer design along with the new "White color" gauges. [edit] Version V (09/98-08/99) - GC8F The power stayed the same as the previous version 280 PS . The engine layout and design was made cleaner and was dubbed as the Boxer Phase 2 engine. The facelift the rest of the Impreza line had was also applied to the STi. The WRX STi weighed 1,270 kg (2,800 lb). There were 1000 WRX Type RA STi Version 5 Limited cars and the WRX Type R STi Version 5 Limited cars had a 4 month waiting period for each order. The interior was also changed slightly from the Version 4 including seats and steering.This model was also produced as a 555 limited edition. [edit] Version VI (09/99-08/00) - GC8G GC8 Production 1999-2000 Body style(s) 2-door coupé 4-door sedan 5-door station wagon Engine(s) 2.0 L H4 Wheelbase 99.2 in (2520 mm) Related Subaru Impreza Subaru Impreza WRX Subaru Forester Again the power stayed the same. Most of the changes were cosmetic. The wing was sculpted to be more aggressive. There were 2000 WRX STi Version 6 Limited, 1000 WRX Type R Version 6 Limited and 2000 WRX STi RA Version 6 Limited cars produced. Also 500 WRX STi Version 6 Limited Hatchback models. [edit] Japanese special variants [edit] 22B STi (03/98 – 08/98) In 1998, Subaru of Japan produced a widebody, 2-door, Impreza called the 22B STi. The 22B was used to commemorate both Subaru's 40th anniversary as well as the 3rd consecutive manufacturer's title for Subaru in the FIA World Rally Championship. On the release of the sales, all 399 sold out from 30 minutes to 48 hours, depending on the report.[7] The cars had the starting VIN code of GC8E2SD. Another 25 were produced for export markets - see the 22B Type UK below. The 22B had the EJ22 engine as opposed to the regular EJ20 engine. (Note internal Subaru material states the block comes from a V3 EJ20G NOT the EJ22G as most think. Also the intake manifold and heads were from the V4 EJ20K) This means the displacement was increased from 1994 cc to 2212 cc. The block is a closed-deck design. The heads (valves, valvetrain and such) were lifted from the STi Version 4 engine. It produce 350 PS (260 kW; 350 hp) at 6000 rpm and 363 N·m (267 ft·lbf, 37.0 kgf·m) of torque at a lower engine speed of 3200 rpm. The redline was lowered from 8000 rpm to 7000 rpm. The compression is an 8.0:1. The turbocharger is an IHI RHF 5HB (the internal company usage code is VF23). This car was given a unique color of blue and had fender flared widebody taken from the Peter Stevens designed WRC car, thus widening the width by 80 mm (3.15 inches) for a total of 1,770 mm (69.7). During assembly, a WRX Type R chassis was taken off the line. The fenders were replaced with the 22B STi fenders. The car's curb weight is 1,270 kg (2,800 lb). The suspension is provided by Bilstein. The brakes were standard 4-piston/2-piston brakes. However, the color is red and the Subaru name cast on the brake calipers and painted white. The wheels were increased in size from the standard WRX Type R STi from 16x7" to 17x8.5" BBS Elektra wheels. The car is shod with 235/40 ZR17 Pirelli P Zeros. The clutch was upgraded to a sintered twin clutch with a ceramic disk. The transmission ratios are the same as the standard WRX Type R, but the gears were shot-peened for added reliability. The car has a unique hood, a WRC-inspired front bumper and a unique adjustable rear wing. The origin of the name 22B has often been debated. Many assume 22 referred to the 2.2 liter displacement and the B was for the Bilstein suspension. This would correlate with the idea that Subaru sells a Legacy Spec B, where the B represents the Bilstein suspension. Others believe that 22B was meant to represent the much recognized 555 decal (555 is a tobacco company that was a major sponsor for Subaru in the WRC) on the WRC car as 22B is a hexadecimal representation of the decimal number, 555. It must be noted that the 22B STi that is 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 went to the World Rally car drivers for Subaru at the time Colin McRae and Nicky Grist, with the third being used by Subaru Japan as their press car. It was widely rumored David Lapworth of Prodrive owned the third #000 car, however he actually owned #400.[8] [edit] S201 STi (2000) Subaru Tecnica International started the S-series of special Imprezas. This series is a limited production series that sports an engine output of greater than 280 PS (210 kW; 280 hp) [had 224 kW (305 PS)] (special variant cars were excluded from the gentlemen's agreement). The car was decked with nearly every single part from the STi catalogue. The S201 was a 4-door STi that sported the only body-kitted S-series WRX STi. It had a tri-planar wing and a massive front airsplitter. The entire suspension was composed of STi parts. There were 300 S201s produced, they used a VF28 spec turbo, with max boost at 1.2 BAR and produced 224 kW (305 PS) and 353 Nm, weighing in at 1270 kg these are a highly desirable variant. [edit] United Kingdom special variants [edit] 22B Type UK (1998) 16 of the 'export' 22Bs (see above) were modified by Prodrive, with longer gear ratios, UK specification lights and an official 3 year warranty. Because 50 22Bs had already been imported privately into the UK, Subaru UK had to wait until 1999 to register the 22B Type UKs under the VCA's Single Vehicle Approval scheme. The price was £39,950, approximately the same price that grey import 22Bs were being sold for. [edit] P1 (2000) To counter the grey imports of high-performance Japanese variants, Subaru UK commissioned Prodrive to produce an 'official' limited edition of 1,000 two-door cars in Sonic Blue.[9] The chassis was a 2-door coupe. They were taken from the STI Type R lines and used for the P1. The car was the only coupe version of the WRX STI GC chassis to receive ABS. In order to allow for ABS, the DCCD was dropped. Engine output was boosted to 276 bhp (206 kW; 280 PS), and the suspension optimised for British roads. Options were available from Subaru consisting of 6 piston front brake calipers, electric Recaro seats, 18" OZ alloys and a P1(Prodrive) stamped backbox. The P1, or Prodrive One, is echoed in the name of the Prodrive P2 concept car.

The chassis was stiffened so that it had 120% torsional stiffness increase. The WRX STi gained 17" x 7.5" alloy wheels over the previous 16" x 7" wheels. The 5 speed manual transmission (reputed to be one of the car's weakpoints) was changed to an STi engineered 6 speed manual transmission. The engine was retained from the Version 6 STi and still retains the semi-closed deck block and is still labeled as the EJ207, However, the turbochargers are IHI models. The interior was updated with a STi logo on the gauge. The STi's tachometer also has a red shift light. The STi's and optioned Type RA STi have received Brembo 4 piston front and 2 piston rear brakes while the bare-bones Type RA STi still carried the Subaru 4 piston front and 2 piston rear brakes. Externally, the STis had larger hood scoops and had foglight covers with STi embossed on them. The DCCD was updated so it can work with anti-lock brakes. During braking, when the ABS is on, the DCCD will set itself to open-mode (no locking). The version nomenclature was dropped from the name. Japanese and other auto-enthusiasts often refer to the chassis as GDB/GDF (the STi has a 'B' or 'F'(for USDM models) where as the regular WRX had an 'A'). The fourth character of the VIN gives the revision (A to F where G is the 2007 version). For quick and easy reference to the different exteriors, Subaru Impreza owners use nicknames based on the headlights. Each relates to a creature that has similar looking eyes: 2002-2003 are 'bug eyes' / 2004-2005 are 'Tear Drop' or 'blob eyes' / 2006-2007 are 'hawk eyes'. [edit] Japanese-spec [edit] Rev. A (2000) In 2000, the WRX STi received the aforementioned updates. The WRX Type RA STi was produced. The STi wagon was still produced but its engine only produced 275 PS (202 kW; 271 bhp) . The STi foglight covers had white STi lettering on them. The WRX Type RA STi was used for the Group N homologation. [edit] Rev. B (2002) Along with the rest of the Impreza line, the grille and body of the WRX STi was minorly updated by Peter Stevens to give it a more angular look when seen from the side. The foglight covers had pink STi lettering. Not much else besides minor suspension improvements and a small increase in torque output was done. The WRX Type RA STi was dropped for a new WRX STi Spec C. This model was much lighter than the WRX Type RA as it received lighter glass and body panels. The Spec C's handling was much improved due to an increase in caster (from 3.5 degrees to 5 degrees). This was achieved not by changing the suspension mounting point, but by lengthening the wheelbase (15 mm). This was done by including different control arms. This increased caster significantly helped the turn-in capabilities of the car. The Spec C also has a steering rack ratio of 13:1. The transmission is supplied with its own oil cooler. The WRX STi wagon had ceased to be produced. [edit] Rev. C (2003) Little change from Rev. B. The WRX STi was used for Group N homologation. [edit] Rev. D (2004) The WRX STi received the same Peter Stevens-designed facelift that rest of the Imprezas received. The WRX STi is now capable of being ordered with DCCD. The WRX STi Spec C Type RA was released. It sported a carbon-fiber wing and a carbon fiber lip. It also had a new set of BBS wheels as well as a newly tuned engine. The WRX STi V-Limited was released. It sports 4-way dampers tuned by Subaru World Rally Team's Group N driver Toshi Arai. The WRX STi was used for Group N homologation. [edit] Rev. E (2004) This was the first Impreza STi model to be offered in the United States. Subaru unveiled this model in the Detroit International Auto Show, only 1 month after Mitsubishi announced the arrival of the 271 horsepower Lancer Evolution 8, which out-performed the 2.0L WRX. The 2004 WRX STi is considered to be the lightest (3263 lbs, official brochure and tested by Car & Driver Magazine) and rawest among 2004-2009 models. The car was sold without a radio or floormats. The car was rated at 300 bhp and 300 lbs-ft torque, although many feel it was under-rated on purpose. What made the car so special to most is the level of performance offered for a mid 30 thousand dollars car, that still has a back seat and a big trunk. Since its launch, many upgrades became available to increase power, handling and braking capabilities. Some weak links were discovered in most 2004-2007 models since the 2004 debut. The IHI VF39 turbocharger wastegate may develop cracks that may or may not affect performance. The oil pickup line inside the oil pan was shown to develop a crack leading to oil starvation and engine damage due to the lack of lubrication when the part fails. Several aftermarket vendors have addressed this issue by re-designing factory oil pickup units with beefier welds/materials. [edit] Rev. F (2005) The WRX STi receives the same increase in wheelbase as the Spec C. All STis received additional rear fender flaring in order to allow an increase in wheel size. The wheel size went from 17" x 7.5" to 17" x 8". In accordance with the increased wheel width, steering lock-to-lock turns have been reduced. Wheel hub strength was improved. The P.C.D. was changed from 5 x 100 mm to 5 x 114.3 mm. The interior was vastly improved as well. A whole new center console now brings out a very high grade interior feel. The WRX STI continues on relatively the same. The Impreza line's looks have been updated. The WRX STI Spec C's receives the Arai tuned dampers and a 21 mm (0.8 in) swaybar. The rear suspension is changed from rubber bushings to pillowball bushings. The strut tower was further stiffened for improved handling and stability. The strut towers were reinforced for better handling and better ride characteristics. The engine mounts were changed from metal to liquid-filled plastic mounts to reduce vibrations into the car's cabin. Some 2006 owners have had issues with these plastic engine mounts. The manufacturer will replace them, under warranty if broken, with the 2005 rubber mounts.[10] The DCCD is updated with the use of a torque-sensing mechanism inside the DCCD. The torque split is changed to 41/59. The WRX STI Spec C was used for Group N homologation. The WRX STI Spec C Type RA was released in November 2005, with 350 units produced. The Type RA added the following to the Spec C model from the STI parts catalogue: 4-way STI adjustable inverted struts, STI Japan-spec pink springs, STI rear lateral links, STI rear trailing links, STI 21 mm (0.8 in) rear sway bar, STI rear pillowball suspension, STI 110 mm (4.3 in) opening rear axleback exhaust, STI 17" x 8" Enkei-made wheels and STI V-lip front spoiler. [edit] Rev. G (2007) The WRX STI and STI Spec C is mechanically similar to the previous revision. Changes include a different turbocharger VF43 equipped with a slightly larger wastegate port to prevent boost creep (VF43, as opposed to VF39 in the older version) and revised gearing on the 6 speed manual transmission. They also use top feed injectors instead of side feed injectors like the previous STi models(04-06USDM). This means the intake manifold is a bit different as well as the TVG (Tumble Valve Generators) used for emissions on cold start-ups. [edit] Japanese special variants [edit] S202 This car was an S-series Impreza based on the Spec C. All of the suspension and powertrain parts included STi parts from the STi part catalogue. The interior included special edition yellow seats with red STi logo stitching. A smaller, lightweight AC compressor was fitted to save weight. The brake rotors were gas slotted. The wheels were STi labeled Rays Volk alloys. [edit] S203 This limited edition Subaru was an S-series Impreza based on the WRX STi. Again it is basically a car with all the STi parts available. It was sold with custom made 18-inch (460 mm) BBS alloys with Pirellis. [edit] S204 The new S204 was released at the end of 2005. It is based on the WRX STi and similar to the S203. It does away with the roof spoiler and has a different grille from the rest of the Impreza line. The S204 has a two-litre (EJ20) H4 engine capable of developing 235 kW (320 PS; 315 bhp) and a six-speed manual gearbox. When cruising the S204 achieves 100 km/h (62 mph) at 3000 rpm in top gear and can reach 220 km/h (137 mph) at 6000 rpm. Suspension can be described as 'stiff' with torsional rigidity enhanced by the inclusion of laterally mounted items described as "performance dampers" bearing both the STi logo and Yamaha. As a result cornering can be described as excellent. The addition of a carbon fibre front-lip spoiler and a rear diffuser on an already low suspension setup plus the use of low-profile Pirelli P Zero (Corsa) tyres implies the S204 is intended mostly for sealed road use. Recaro has used carbon-fibre extensively in the manufacture of the driver and front passenger seats available in the S204. The high side bolsters provide significant support to the driver during maneuvers that induce lateral forces and are considered to be an integral feature to the cornering performance of this vehicle. The seats are rigid in design and have relatively little cushioning compared to other Impreza Models. Internal rear view of Recaro Seats in the Subaru S204. Note: Use of carbon fibre in construction. Internal front view of Recaro Seats in the Subaru S204. Note: High side bolsters for lateral force support. Advertising material produced by Subaru for the S204 indicate that a limited run of 600 S204's were made. Individually numbered badges for each car are located within the engine bay and repeated as a small plaque situated at the base of the gear lever. However, five (5) WRX STI S204 were made available to Subaru enthusiasts in New Zealand <http://www.subaru.co.nz/About_Subaru/News/index.php?article=887>. Unlike other S204s sent to other nations (for example Singapore) these five cars do not display either the in-cabin or in-engine bay badging that uniquely identifies each of the reported 600 vehicles manufactured. The lack of individual badging for these five cars brings into question the real number of S204s manufactured. [edit] WRX STI Spec C Type RA-R At the end of October, 300 2007MY WRX STI Spec C Type RA-Rs were open for ordering. These cars are based on the WRX STI Spec C. The wheels are changed for 18-inch (460 mm), STI-branded, Enkei-made, white wheels. The engine has been blueprinted and balanced. It produces 320 PS (235 kW; 316 hp) of power. The suspension is built with the latest STI parts from the STI catalogue. The front brakes are 6-piston brembo brakes. The turbo charger is based on the larger S203/S204 twinscroll unit. The brakes are made so that they change from silver to gold when heated from usage. The rotors are slotted. The 2nd R in "RA-R" is stated by an STI engineer to mean "Radical".February 2007 Edition Best Motoring Interview of STI engineer at 7:00 [edit] WRX STI A-Line This WRX STI A-Line is mechanically the same as the Japan-spec STI. The exterior has been toned down with the removal of large rear spoiler, black Brembo brakes, titanium colored Enkei wheels, a black STI front lip and leather seats in order to target the more mature market. [edit] Asia, Oceania and European specifications In 2000, most of Asia, Oceania and Europe received the new STi. The engine was detuned to meet emission standards. Engine output was variously rated from 265 PS (195 kW; 261 hp) to 280 PS (210 kW; 280 hp) depending on market. 2005 STis received the long awaited DCCD control available in other markets, as well as a slight wheelbase increase to match the Japanese-spec WRX STi Spec-C and has 280 PS (210 kW; 280 hp). In 2006, the model was facelifted like all STIs and the engine was changed to the EJ257 producing 280 PS (210 kW; 280 hp).

[edit] WR1 (2004) A limited edition of 1000 Japanese MY04 WRX STI's with DCCD were exported to celebrate victory in the 2003 WRC drivers' championship. 500 were sold in Europe, Australia and South Africa as the Petter Solberg edition; the other 500 were further modified by Prodrive and sold in the UK as the WR1. They had 316 bhp (236 kW) and 309.8 ft·lbf (420.0 N·m), an incredible 0-60 mph time of only 4.25 seconds and a top speed of 155 mph (249 km/h) (electronically limited). They were equipped with Prodrive WRX STI springs, Pirelli PZero Nero tires, mesh grilles, special Ice Blue metallic paint and Prodrive PFF7 Pewter wheels. The new ECU and exhaust were not EU-homologated, so they were fitted after registering the car. The retail price was £29,995. [edit] Spec D (2006) A 'discreet' version of the STI was made for a more conservative market. It is similar to the Japanese-spec A-Line except it had a regular WRX spoiler on the boot, silver wheels (not Gold) and no rear roof vane. As standard it has projector-style fog lights, Smartnav with touch screen operation, Vehicle Tracker,and safe speed system. A 200W Pioneer DEH-P70BT head unit, iPod adapter and Bluetooth phone connection were also included. The interior featured standard leather trim on the seats and doors, Auto climate control and extra sound insulation. It was limited to a run of 300 cars in only Crystal Grey Metallic so therefore is even rarer than the RB320. Power on this model is rated at 276 bhp (206 kW). It has a 0-60 time of 5 seconds and a top speed of 155 mph (electronically limited). New retail price was £28,450. [edit] RB320 (2007) Subaru Impreza RB320 Echoing the RB5 a limited edition of 320 2007MY cars in Obsidian Black Pearl were released "in memory of Richard Burns", the 2001 WRC World Champion who died in 2005 due to a brain tumor. The car produces 320 PS (235 kW; 316 hp) of horsepower and 450 N·m (332 lb·ft) of torque due to tuning by Prodrive. The suspension has been upgraded with Eibach springs, an Eibach rear stabilizer bar and Bilstein struts. It rides on 18" anthracite alloys. A £1500 option on the car was to have the interior changed to a black leather/alcantara with RB320 stitching on the seat and a new gear (shift) knob. The car has special silver mesh grilles. New retail price was £29,995.[11] [edit] United Kingdom unofficial variants [edit] Litchfield Type 25 (2004) Litchfield Imports[12] initially imported Japanese specification Subarus, including the Spec C, into the UK. The motivation for them to create a new version of the Impreza came when Subaru removed creature comforts like air conditioning and electric windows from the Spec C at the end of 2003. Iain Litchfield wanted to continue to offer an 'everyday' Impreza as fast as the Spec C. Litchfield saw the potential of the newly released USDM EJ257 and imported it, He modified the heads, tuned it to produce 350 bhp (261 kW). The engines were installed into a Japanese specification STI and upgraded the suspension with rebound adjustable AST Sportline I coilovers, Whiteline anti-roll (stabiliser) bars and an anti-lift kit. The May 2004 edition of EVO magazine.[13] called it the 'Best Impreza Ever' when tested against the WR1, Spec C and P1. [edit] Litchfield Type 25 (2007) The new Type 25, like the previous Type-25, used a modifed EJ257 block but it was built by the US arm of Cosworth. They used Cosworth’s own forged pistons and connecting rods balanced to within 0.5 grams. A modified STI crankshaft and STI engine casing were used and the 'short' engine was assembled by hand. This ‘short’ engine was sent to Litchfield to be finished . Cosworth honed, big-valve, ported cylinder heads and cams were used and the engine was installed into a 2007 Japanese specification Spec C. The engine produces over 415 bhp (309 kW) and 420 lb·ft (569 N·m), for a power/weight ratio 1 hp higher than a Porsche 997 Turbo.It costs $10,000 more than the normal 2006 Subaru Impreza WRX STI. [edit] US-spec [edit] Rev. D (2004) In 2004, Subaru of America announced it would sell the WRX STi. Subaru Tecnica International's president said in an interview with Road & Track magazine that he wished to beat the Mitsubishi Lancer Evolution in the US. Thus, each iteration of the US-spec WRX STi is essentially the same as the respective J-spec STi Spec C. All part numbers matched up, including the part-numbers for the glass windows and dampers. However, instead of the EJ207, the USA receives the first EJ257, a 2.5 liter version of the EJ207. Unlike the EJ207, it features hypereutectic cast pistons as opposed to the forged pistons in the EJ207. The steering rack is the standard STi's 15.2:1 instead of the Spec C's 13:1 [edit] Rev. E (2005) As with the Japanese-spec C models, US-spec STis received additional rear fender flaring in order to allow an increase in wheel size. The wheel size went from 17" x 7.5" to 17" x 8". In accordance with the increased wheel width, steering lock-to-lock turns have been reduced. Wheel hub strength was improved. The P.C.D. was changed from 5 x 100 to 5 x 114.3. The Suretrac front LSD in the 04 model was replaced with a helical unit, the rear differential remains the same clutch type unit. Torque split is set at 35/65. In the interior, the Stereo became standard. The badging has been revised and different look was given to the steering wheel, shift knob, HVAC controls, and center console. [edit] Rev. F (2006) The US-spec STIs receive the same facelift as the Japanese-spec STIs. Mechanically speaking, the DCCD (Driver Controlled Center Differential) and the engine mounts have been changed. Like the Japanese-spec STIs engine mounts were changed from metal to liquid-filled plastic mounts to reduce vibrations into the car's cabin. On the largest Impreza forum, North American Subaru Impreza Owners Club (NASIOC), 2006 owners have had issues with these plastic engine mounts. The manufacturer will replace them, under warranty, if broken, with the 2005 rubber and metal mounts. Later 2006 vehicles were equipped from the factory with 2005 mounts. The center differential is updated with the addition of a mechanical limited slip mechanism to supplement the electromagnetic DCCD. The torque split is changed to 41/59. The 2006 STI weighs approximately 3,350 lb (1,520 kg). [edit] Rev. G (2007) 2007 US-spec Subaru Impreza WRX STi Limited. Only 800 were produced. In 2007, quite a number of changes were made to the US-spec model. Due to Subaru's decision to reduce costs by cutting the amount of aluminum used, the US-spec STI no longer receives the J-spec Spec C control arms. The control arms are now the aluminum ones used on the Japan-spec revision A and B non-Spec C STis. The high caster angle has been reduced, which in turn reduces the wheelbase from 100" to 99.4". The rear sway bar has decreased in size from 20 mm (0.8 in) to 19 mm (0.7 in). The gear ratios of second, third and fourth gears have been made longer (higher ratio) in order to improve fuel economy and driveability, which inadvertently reduces 1/4 mile drag racing times due to the ability to trap 114 mph (183 km/h) in 4th gear, without the shift to 5th. The EJ257's cylinder heads have been redesigned to improve cooling, and the sodium-filled exhaust valves have been deleted. Pistons are the same as previous years. The alternator is changed from a 90A rating to 110 amps. The rear Limited Slip Differential is now a Torsen unit, considered an upgrade over the previous model's clutch type unit. The turbo has also been changed to the VF43, which has a different wastegate actuator than the VF39. The side cowl braces are stiffer than the 2006MY. The engine mounts are once again the hard rubber mounts used prior to 2006. On the interior, there is an audio jack that replaces the ashtray, a rear center armrest with trunk pass-through and a 120 W audio system.[7] The ECU was completely re-engineered in order to meet US LEV2 emissions requirements, which has caused throttle and timing issues. A secondary air pump was also added to help meet LEV2. Top Feed injectors replaced the Side Feed from the previous models. The WRX STI Limited was introduced with fog lights, leather interior, lip trunk spoiler, and optional moonroof. It is similar to the Japan-spec WRX STI A-line, except the mechanicals of the car are based on the 2007MY US-spec WRX STI. [edit] GC chassis comparison to the GD chassis [edit] Pros Subaru claims that the GD chassis is 10 percent and 82 percent stiffer in torsional and beam rigidity, respectively, than the GC chassis. Due to the increase in stiffness, the car has much better stability in corners and is easier to control at the limit. In terms of safety, the GD chassis scored much higher than the GC chassis and earned a "Good" rating (highest mark) from the IIHS's offset crash test. 4 stars front driver, 5 star front passenger and 4 star side safety ratings from the NHTSA. In a magazine article from the December 2005 Firehouse magazine (a periodical written by and made for firefighters), Ron Moore writes how it is well-known that the Impreza chassis has great protection in its B-pillars. This side structure has 8 layers of high-strength, high-tension steel including a round steel bar running through the middle. The author notes how drivers simply walk away from horrific side-impact accident. [edit] Cons One of the biggest complaints with the GD chassis is that it gains nearly 200 kg (441 lb) in weight over the GC chassis. Much of this weight came in the form of chassis stiffening as the car was made to meet every country's crash standards. The weight also hampers the cars maneuverability, transitions and turn-in capabilities. The GC Imprezas were notable for being very lightweight despite having AWD, the WRX Type STi Version VI, at 1,260 kg (2,778 lb), was lighter than the concurrent Mazda RX-7 type RZ (1270 kg) and Honda NSX type S Zero (1270 kg). In this fashion, the GC chassis has a better advantage. However it still remains at a slighter weight by shaving 200 pounds off of its biggest competitor, the Mitsubishi Lancer Evolution. The author mentioned above also notes that the Jaws of Life need to cut the Subaru's B-pillars at certain points in order to cut through the car frame.[14] [edit] Third generation (2008-present) Third generation (GR) Production 2008-present Body style(s) 5-door hatchback 4-door sedan(2011-) Engine(s) 2.0L 304 hp (227 kW) H4 2.5L 305 hp (227 kW) H4 Transmission(s) 6-speed manual[15] 5-speed automatic (w/SPORTSHIFT manual mode) (Japan, Hong Kong, Singapore, Indonesia, and Australia only) Wheelbase 103.3 in (2,624 mm) Length 173.8 in (4,415 mm) Width 70.7 in (1,796 mm) Height 58.1 in (1,476 mm) Curb weight 3,373 lb (1,530 kg) Related Subaru Forester Subaru Impreza Subaru Impreza WRX Subaru Impreza WRX STI 2008 The 2008 STI has received a higher degree of parts to differentiate it from its Impreza WRX brethren. Unlike the Impreza WRX, the STI uses aluminum suspension components, is only available as a 5-door hatchback, and has different fenders that are 2.2 in (56 mm) wider. It adopted "Subaru Intelligent Chassis Design" and "Dynamic Chassis Control Concept". The turbo forces air through a larger top-mount-intercooler which has lost the red "STI" that was on previous generations. It is the first generation of this model with an automatic transmission which is able to import to outside Japan. Like other 2008 Impreza models, the 2008 STI benefits from a lower polar moment of inertia due to smaller overhangs, and also features a double wishbone rear suspension.[16] The car also borrows new intake and exhaust components from the Legacy GT platform. The latest Impreza WRX STI features Multi-mode Vehicle Dynamics Control (VDC) with "Normal", "Traction", and "Off" modes, Subaru Intelligent-Drive (SI-Drive) with 3 modes: Intelligent, Sport, and Sport Sharp (S#), and Multi-mode Driver's Controlled Centre Differential (DCCD). The DCCD enables driver to select the manual or auto: "auto", "auto+", and "auto-" mode in order to distribute the torque based on driving preference or conditions. Subaru Impreza WRX STI (Japan) The JDM version has a 2.0L 308 PS (227 kW; 304 bhp) EJ207 engine with a Twin scroll turbocharger, while other versions of the car have a 2.5L 300 PS (221 kW; 296 bhp) EJ257 engine with a single-scroll VF48 turbocharger. At the New York Auto Show, a Subaru spokesman confirmed that the Impreza WRC will be based on the hatch platform, due to its lower polar moment of inertia.[16] The latest US model of the STI has 305 bhp (227 kW; 309 PS) and 290 ft·lbf (390 N·m). of torque and range in price from $35,640 to $39,440, depending on the options included. The 2008 Impreza STI has the model code GR, reflecting the different "wide body" 5-door Hatchback compared to the GH standard body 5-door Hatchback used for the 2008 Impreza WRX and non-turbo models. The new "wide body 5-door" chassis is 70.7 in (1796 mm) wide compared to 68.5 in (1740 mm) for the regular WRX 5-door chassis. Kerb weight varies from 1,505 kg (3,318 lb) to 1,540 kg (3,395 lb) depending on the options. In 2008, a Subaru WRX STI spec C was in the works for production. It had been spotted lapping the Nurburgring. It is expected to shed 70 kg (154 lb) in weight, have minor engine tweaks, have an updated aero kit, and bigger brakes. A possible precursor to the WRX STI spec C had surfaced at the MotorSport Japan 2008 auto show, named the Subaru Takumi concept. The only visual cues to differentiate this car from the regular STI are a blacked-out rear spoiler, front lip spoiler, and 12-spoke wheels that are strikingly similar to the ones featured on the spec C test mule spotted around the Nurburgring. The upgraded parts included on the car are drivetrain and suspension modifications. There is no word on performance figures or power output. It was later confirmed by Autoblog that the Takumi concept was in fact just an unveiling of the 20th Anniversary Edition WRX STI and not the spec C.[17] All 300 examples will be exclusive to the Japanese market.[17] Subaru launched the Impreza WRX STI A-Line with a five speed semi-automatic gearbox on February 24, 2009. Available initially only in Japan and Singapore, the A-Line features include “Downshifting Blipping Control” and steering wheel-mounted paddles.[18] The engine and transmission in the A-Line are very similar to 2007-2009 Legacy 2.5 GT models. However, the A-line has less torque (35.7kgfm) and slower acceleration (0 to 100 km/h takes 6.1 seconds) compared to the manual STI version. The A-Line is also offered in Hong Kong, and later in Indonesia with debut at the 2010 Indonesia International Motor Show in July 2010, and will be exported to Australia in 2011.[19] Finally, on July 23, 2009, the Subaru Impreza WRX STI spec C was released in Japan. The 900 units limited edition WRX STI spec C has engine, suspension, and body parts improvement over the regular model. The ball bearing on the turbine axle had been modified to reduce friction, the ECU had been retuned for better response, and an intercooler water spray was fitted to prevent rise in the air temperature. The cross member, suspension and power steering were also improved for better handling and body rigidity. Aluminium hood, laminar window glasses, and lighter battery helped to reduce weight. Subaru (UK) Limited introduced two new WRX STI models at the British Auto Show that have specific tuning by Prodrive. The first is WRX STI 330S, intended to compete with the UK-spec Lancer Evolution X FQ-330. It produces 330 PS (243 kW; 325 bhp) and has a 0-60 mph time of 4.4 seconds. The last of the two would be the WRX STI 380S. It could make it into production within 6 months, pending positive consumer reception. It sports new wheels and an upgraded body kit. It is expected to produce 380 PS (279 kW; 375 bhp). Currently, there are no other specs for the car. Subaru announced, on September 10, 2008, that the 380S variation will not be produced, due to homologation and specification difficulties. The regular model is called WRX STI Type UK. 2010 Subaru Impreza WRX STI with optional BBS wheels The Singaporean, Indonesian, and Australian (all RHD countries) markets received the 2.5 liter Euro-spec version instead of the J-spec version, producing 296 horsepower (221 kW) and 407 N·m (300 lb·ft) of torque.[20] Some of Impreza WRX STI's sold in Indonesia are the 2.0 liter JDM spec brought by the general importers before Subaru officially introduced the 2.5 liter model. In Australia the regular WRX STI is sold alongside the WRX STI spec.R which comes with BBS wheels and Recaro seats. For 2010 model year, Subaru of America introduced the Impreza WRX STI Special Edition. Similar to JDM WRX STI Spec C, this model came with stiffer suspension and thicker stabilizer bar for better handling. It also has 7 twin-spokes dark gray 18 inch alloy wheels. Inside, the limited-run Special Edition STI got manual air conditioner and 4-speaker stereo instead of automatic climate control and 10-speaker premium audio on the regular WRX STI. [edit] Cosworth Impreza STI CS400 Available for the UK market only, the Cosworth Impreza STI CS400 was announced in late May 2010. Only 75 units built, the STI CS400 is powered by a 400 PS (394Hp) 2.5 liter turbocharged engine which has Cosworth engineered forged connecting rods, racing pistons, heavy duty cylinder head studs, multi-layered head gasket, and high pressure oil pump. The ECU had been remapped, and the new compressor design and wastegate actuator had been applied to the turbo. The exhaust system features larger capacity tubular manifold and bigger diameter downpipes. Clutch was also upgraded. The Cosworth Impreza STI CS400 can be distinguished from the regular STI from its upper mesh grille with piano black finish on the top frame, modified front bumper with "Cosworth" emblem on the lower mesh grille, and lip spoiler, 18 inch Pro-Race alloy wheels in Antrachite Gray, and trunk waist spoiler. To match its performance, the CS400 comes with Bilstein struts and Eibach springs for better quality ride, and better handling with less pitch and roll during cornering. Braking was updated by AP Racing's larger diameter ventilated front brakes with six-pot calipers. Inside, the CS400 has Recaro leather seats with "Cosworth" label, piano black center console panel, and "Cosworth"-badged floor mats. [edit] Facelift models (2011-) The 2011 model year Impreza WRX STI will be offered in the 4 door Sedan bodystyle once again after a three year absence from the STI line-up since the introduction of third generation model. The new WRX STI Sedan is built as "wide body" with flared fenders, front skirts, and rear valance, while the Hatchback model also come with similar treatments. The most noticeable feature on the STI Sedan is a large rear wing, characteristic of the last generation Impreza STI Sedan. With the new front bumper, the 2011 Impreza WRX STI is more aggressive compared to 2008-2010 models. The 2.5 flat four turbocharged engine with 305 horsepower is carried over, while tweaks in suspension will improve handling. The 2011 model year STI has stiffer spring, bigger anti roll bar, and new pillow ball bushings on the front lower arms. Also, US dealers are now requiring synthetic oil for 2011 models. It will now do 0-60 mph in 5 seconds and the quarter mile 13.7 seconds It should also be noted that, in Japan, the WRX STI models lack the Impreza name. They are officially referred to as the Subaru WRX STI 4-door and Subaru WRX STI 5-door.

Save Back To Range Overview Engineering Engine & Transmission AWD Safety Interior Compare The range UNCOMMON THINKINGWe don't make cars like other people. That's why the Subaru WRX STI is like nothing else on the road. It combines power with precision and rally-bred performance with everyday practicality, putting it in a class of its own. This difference begins with the supreme balance and control that comes from permanent Symmetrical All-Wheel Drive and the Subaru Boxer engine. These two work perfectly together to create a harmony of power and control that extends to every component found on the WRX STI. The result is a vehicle that excites in every corner, exhilarates with every rev of the engine, and inspires every time you take hold of the wheel. We call it uncommon thinking.UNCOMMON STYLEUnlike other cars, the WRX STI doesn't just excite while in motion. Styling both inside and out, are designed to touch the emotions and passions of performance enthusiasts. Its dramatic lines and intuitive controls raise the hairs on the back of your neck before you even turn the key. And yet, each and every design element has a serious purpose behind it. Each is intended to heighten the performance of the WRX STI, helping you get the most out of driving. At the same time, its design offers surprising practicality, helping you get the most out of your life. The latest WRX STI 4-door demonstrates the same passion for driving with its aggressive lines and wide-body design.STYLED TO INSPIREThe serious performance capability of the WRX STI is immediately evident, even from the outside. Stunning high-strength, lightweight 18-inch alloy wheels are standard. The functional hood scoop and advanced HID headlamps add purpose and presence to the aerodynamic nose. Meanwhile, the four exhaust pipes and roof spoiler on the 5-door, leave a lasting impression as the WRX STI accelerates away. Feedback From The Web Follow Subaru WANT TO STAY IN TOUCH?

Email Address UNCOMMON PERFORMANCEThe horizontally-opposed design of the Subaru Boxer engine lays the cylinders 180 degrees apart on each side of the crankshaft, for superb balance and reduced vibration. Its compact layout helps lower the centre of gravity of the entire vehicle, enhancing both stability and driving excitement.UNLIKE OTHER MANUFACTURERS, WE NEVER STOPHere at Subaru, we have an uncommon passion. For us, the pursuit of performance perfection never ends. That’s why the 2011 Subaru WRX STI features design enhancements that intensify its handling prowess. Using our Dynamic Chassis Control Concept (DC3), all the design elements of the WRX STI work in harmony. From its rigid frame geometry for outstanding cornering to Symmetrical AWD, which provides fierce traction while helping balance the chassis. Every element works together to create precise steering and dynamic cornering. It also features a redesigned suspension for an even greater connection between driver and vehicle. After extensive testing the 2011 WRX STI’s suspension is stiffer and tuned for greater precision. It also lowers the WRX STI for tighter cornering and more immediate steering response. With this new suspension setup the WRX STI gives you intuitive feedback and control that makes driving pure inspiration.UNLIKE OTHER CARS, WRX STI HARNESSES THE WIND The design of the WRX STI directly reflects its motorsport pedigree and the latest in aerodynamic science. A wide stance and short overhangs instill it with high stability and excellent manoeuvrability. Large air intakes feed the engine and turbo intercooler and aid under-bonnet cooling. Prominent wheel arches with functional outlets efficiently manage airflow around the large wheels, while pulling heat away from the engine and brakes. The deep front bumper, side sills and spoiler generate roadholding downforce, keeping you glued to the road. Underneath, a redesigned under cover, which runs the length of the car, works with a rear diffuser to smooth the flow of air. Feedback From The Web Follow Subaru WANT TO STAY IN TOUCH?

Email Address UNCOMMON INTENSITY2.5LITRE DOHC TURBO SUBARU BOXERMAX OUTPUT: 300 PS / 6,000 rpmMAX TORQUE: 407Nm / 4,000 rpmFUEL ECONOMY: 26.9 mpgCO2 EMISSIONS (EU V STANDARD): 243 g/kmEvery WRX STI comes standard with a wide array of technologies, all dedicated to taking the experience of high performance driving to the next level. And at the core of the WRX STI beats the heart of a champion — the turbocharged 2.5-litre Subaru Boxer engine. This award-winning powerplant produces 300 PS of turbocharged power and maximum torque of 407Nm. The engine features Dual Active Valve Control system, optimised combustion and free-flowing four-outlet exhaust for instant acceleration, inspiring response and an intoxicating sound from idle to red line.MULTI-MODE DCCD (DRIVER’S CONTROL CENTRE DIFFERENTIAL)Unlike other cars, with the WRX STI you control the set up. DCCD’s multi-step manual mode and three automatic modes allow the driver to dial in two types of centre differential locking, for the ideal balance of traction and agility on any road surface. Starting with a 41/59% front/rear torque split, DCCD adjusts both an electromagnetic multi-plate transfer clutch and mechanical locking of a Limited Slip Differential (LSD) to split the torque to the front and rear wheels.MULTI-MODE VEHICLE DYNAMICS CONTROL SYSTEMThree selectable modes offer you flexible performance for different driving conditions. Normal mode fully engages Vehicle Dynamics Control, traction control and ABS for maximum response to detected loss of control. Traction mode raises the threshold for intervention by the Vehicle Dynamics Control and traction control systems, allowing you to maximize the torque delivered to the wheels. You can even select off mode for complete deactivation of Vehicle Dynamics Control for maximum driver involvement.SI-DRIVE (SUBARU INTELLIGENT DRIVE)SI-DRIVE lets you adapt the driving character of the WRX STI to your liking. Put it in Intelligent mode for smooth power and optimal efficiency. Select Sport mode for versatile command of every condition. To extract the maximum response from the turbocharged engine, switch to Sport Sharp mode. It gives you the most direct throttle response and precise rev control across the entire rpm range.6-SPEED MANUAL TRANSMISSION With its short stroke, smooth, direct action and leather- wrapped gear shift, the 6-speed manual transmission lets you savour every sweep of the glowing red rev counter. As you match revs to extract the most of the engine's bountiful torque curve, you'll feel all the performance potential of the WRX STI firmly within your grasp.

Email Address UNCOMMON BALANCE PERMANENT SYMMETRICAL ALL-WHEEL DRIVE Since introducing permanent Symmetrical All-Wheel Drive in 1972, Subaru has continually advanced its technology to meet the evolving needs of drivers around the world. A Subaru is engineered to deliver the best possible traction and stability through its AWD, with its engine and drivetrain in a symmetrical, straight-line layout. Power is routed to all four wheels simply and directly, for perfect balance and an innate sense of control.AN UNCOMMON CONNECTION TO THE ROADWe don't think like other car manufacturers, that's why Subaru's are unlike most other cars. Since 1972, Subaru cars have been defined by their perfect symmetry. The core elements of our permanent Symmetrical AWD - the engine's crankshaft, transmission, driveshaft and rear differential - all run in a continuous line along the centre of the vehicle. And with its longitudinal alignment and horizontally-opposed pistons, the Subaru Boxer engine is the ideal companion to Symmetrical AWD. Combined, they deliver unrivalled balance and stability, delivering handling and acceleration that brings you in touch with the road and setting the WRX STI apart from everything else.Symmetrical balance, along with a compact layout and lower centre of gravity means less roll on corners which helps give the vehicle greater stability. What's more, the system instantly reapportions the engine's torque between the front and rear wheels as conditions demand, providing powerful traction for more capable performance on any road.

Email Address UNCOMMON CONFIDENCETruly enjoyable driving comes from confidence in your vehicle and unlike other cars, the WRX STI exudes confidence. Every Subaru is designed with a commitment to the highest standards of safety and the WRX STI is no exception. It's equipped with advanced active safety systems, which continually work to help keep you in control and give you the power to steer clear of potential dangers. And should an unfortunate event occur, the WRX STI surrounds you with passive safety systems of exceptional strength, helping to protect you and your passengers. These systems combine to give you the reassurance you need to drive with true confidence.UNCOMMON SAFETY ACTIVE SAFETY, TO AVOID A COLLISIONMany of the same features that make a WRX STI fun to drive also help keep its occupants out of harm's way. The stable, responsive handling of its permanent Symmetrical AWD is enhanced by the low centre of gravity of its Subaru Boxer engine. It comes as standard with an advanced Multi-mode Vehicle Dynamics Control system and surefooted suspension. Its powerful Brembo brakes further enhanced with Super Sport ABS and Electronic Brake Force Distribution. These features, combined with quick steering, work together to equip the driver with excellent evasive abilities.PASSIVE SAFETY, TO BETTER SURVIVE A COLLISION The WRX STI is designed with occupant protection as a high priority. Its body structure is intelligently strengthened in critical areas to help minimise the impact energies that reach the cabin. Front SRS airbags*, front-side and curtain SRS airbags*, along with 3-point seatbelts help protect occupants directly.SEATS, SEATBELTS AND AIRBAGSHeight adjustable front seatbelts feature pre-tensioners to hold passengers firmly in place and load limiters that ease peak forces to the chest. Front SRS airbags* are standard, as are front-side and curtain SRS airbags*. And a tether and ISOFIX anchors allow the installation of compatible child safety seats.RING-SHAPED REINFORCEMENT FRAMESThe Ring-Shaped Reinforcement Frames strengthen the passenger cabin from the roof to the doors, pillars and floor. This design helps to divert and dissipate impact energy away from the occupants in a collision. The front crumple zone is integral to the frame.*SRS: Supplemental Restraint System. Must be used in conjunction with seatbelts. Feedback From The Web Follow Subaru WANT TO STAY IN TOUCH?

Mitsubishi seems to introduce a new version of the Lancer Evo every five minutes, leaving rival Subaru with no option but to continue coming up with tweaks for the Impreza. Here's the latest offering from the Subaru camp. The 2005 model-year Impreza WRX STi Type-UK is, like the car it replaces, quite well described by its title. It's based on the normal Impreza WRX, but with a huge amount of input from Subaru Tecnica International, which has, for example, replaced around 80% of the turbocharged two-litre engine's components in its efforts to raise power output to 262bhp. The Type-UK suffix indicates that this car is significantly different from the STi sold in Japan, though the changes are mostly to do with things like security and emissions rather than performance or handling. Headline features of the STi include items which will keep pub conversation going for quite a while but do not, I think, add anything significant to the ownership experience. The fact that there's a dashboard button which allows you to spray water into the turbo intercooler comes into this category, as does the existence of driver-adjustable control for the centre differential. This allows you to choose between sharp turn-in and stable straight-line running, but realistically the effect is not going to be noticeable on public roads unless you are driving insanely. More importantly, there's a new and quicker-acting front differential, a yaw-rate sensor and revised suspension which increases the wheelbase by 10mm, widens the rear track by 15mm and adds 1.5 degrees to the castor angle. Springs and damper rates have been re-thought, and there are stiffer anti-roll bars. Clearly the STi folk have been busy here, but the basic Impreza package of soft but well-damped suspension aided by a relatively low centre of gravity (contributed by the layout of the flat-four engine) and with power distributed among all four wheels remains unchanged. This is a great basis to work from, and the new-for-2005 adjustments seem to be without exception beneficial to the package. The last STi I drove was great, but this one is better - even more sure-footed when you're driving it quickly, yet even more sedate and user-friendly when you're just pottering around, in the unlikely event that you ever want to do that. The engine contributes to this dual personality. It has the same power as it did before, and nothing really happens below 3000rpm, when the turbo kicks in good and proper. Keep the revs below this figure and the STi is very tame, with a ride quality which I actually rate more highly than that of the standard WRX. Stay above 3000 (not a difficult job with six very closely-spaced gear ratios to choose from) and you have to concentrate hard because of the power, but at the same time the sovereign chassis and the excellent brakes do their best to help you.

The free items include the Prodrive Performance Pack, which further improves acceleration, and stylish new 18-inch alloy wheels and tyres. The Performance Packs, developed in conjunction with Banbury-based tuning experts, Prodrive, adds a reconfigured ECU and high-flow sports exhaust to the Impreza’s already impressive performance arsenal. The PPP increases power output from 230PS to 265PS, while torque increases from 320 Nm to a staggering 390 Nm delivered from just 3,000rpm. The 18-inch anthracite GT1 alloy wheels, meanwhile, give the car a more aggressive, purposeful stance and improve handling and grip. As if the prospect of this extra equipment wasn’t tantalising enough, the Japanese firm has reduced the retail price of the All-Wheel Drive WRX by £95. Subaru UK Marketing Director, Kenyon Neads, said: “With this offer we’ve added even more value into the Impreza equation. The WRX and STI are performance-car icons with a seriously loyal following and we hope that the prospect of these free upgrades will broaden their appeal still further.” The free PPP offer applies to new WRX and STI Type UK models purchased and registered between 1st April and 30th June 2010. 0-62mph acceleration figures Impreza WRX (standard car): 6.5 seconds Impreza WRX (with Prodrive Performance Pack): 5.9 seconds Impreza STI Type UK (standard car): 5.2 seconds Impreza STI Type UK (with Prodrive Performance Pack): 4.8 seconds Related articles Subaru Impreza Design Concept unveiled at LA Auto Show The 2011 Subaru Legacy Outback New 2011 Subaru Impreza WRX STI available now from £32,995 The New Cosworth Impreza STI CS400 400 PS Cosworth Impreza STI CS400 on sale June 2010 New Subaru Outback on sale now New Subaru Legacy Tourer on sale now The new Subaru Impreza Boxer Diesel Subaru Impreza WRX and STI Type UK get PPP (Prodrive Performance Pack) for free Popular articles BMW X8 Citroen DS3 New Fiesta ST Focus RS Limited Edition Subaru Impreza Free PPP Focus MP350 RS upgrade Mercedes G Wagon New Volvo S60 Renault Wind New SEAT Leon Cupra R Goodwood Motor Show Alfa MiTo MultiAir Site links Home Features News Road Tests About TestDriven Contact Privacy Policy Terms & Conditions Site credits Copyright © TestDriven 2010 All Rights Reserved Built by tagfire
