GC chassis (1992-2000)

There were 6 noted versions of the WRX. The STI versions were marketed with consecutive numbers. Another way to tell the version of a WRX was to look at the chassis code. All WRX sold between 1992 and 2000 have the beginning chassis code of GC8 then followed by a letter from A to G.

GC8A (11/1992-9/1993)

The WRX debuts in November 1992 with 240 PS (177 kW) at 6000 rpm with 31 kg·m (304 N·m) at 5000 rpm. It comes with 15 inch wheels. Both front and rear brake rotors are ventilated disks. The vehicle has a curb weight of 1220 kg (2690 lb). The center differential is a viscous coupling type. The rear LSD is a viscous type. The WRX Type RA (marketing has made usage of the RA acronym in various ways; Record Attempt^[1] is the current usage. "R = Racing, A = Group A, the FIA 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) is a stripped down version of the WRX for people to purchase for motorsports. It does not have many "creature comforts" such as air-conditioning or a radio. The car also lacks anti-lock brakes. The WRX Type RA has the same mechanical specifications as the WRX except it had a weight reduction to 1170 kg (2579 lb). The WRX Type RA steering wheel is a 3 spoke leather-wrapped wheel from Nardi.

GC8B (10/1993-8/1994)

October 1993 introduces the 1994MY WRX which produces 240 PS (177 kW) (236 bhp) at 6000 rpm with 28.5 kg·m (279 N·m) at 3500 rpm. The wheels stay the same size. The rear rotor is changed to a solid disk. The vehicle gains 30 kg (66 lb) to a total curb weight of 1250 kg (2756 lb). October 1993 is also the start of production of the wagon version, with 220 PS.

It is also debated whether or not it was just the GF8 Wagon received the 220 PS engine or if the 1994 WRX received it as well. Previously this entry stated the WRX engine was downgraded to 220PS.

GC8C (9/1994-9/1996)

In November 1994, the WRX had a power increase to 260 PS (191 kW) at 6500 rpm with 31.5 kg·m (309 N·m) at 5000 rpm. The wheel diameters were increased to 16 inches and brake rotors were both changed to ventilated disks. With these modifications, the curb weight decreased to 1230 kg (2712 lb). In Japan, the WRX was also offered in the Sport Wagon and was called the Impreza Gravel Express but was discontinued due to very limited sales.

The 1996MY WRX debuts on January 1996. The WRX design received minimal mechanical changes, but a WRX V-Limited Edition was introduced to celebrate the success of the Impreza WRC car in the FIA WRC. It is mechanically the same to the WRX but has a curb weight of 1240 kg (2734 lb). The V-limited cars are painted in World Rally Blue. The World Rally Championship (WRC) is a rallying series organised by the FIA, culminating with a champion driver and manufacturer. ...

GC8D (9/1996-9/1997)

In September 1996, the WRX was updated with new styling. The 1997MY WRX now has a power rating of 280 PS (206 kW) at 6500 rpm with 33.5 kg·m (329 N·m) at 4000 rpm (280 PS at 6500 rpm with 352N*m 4000rpm for the wagon version). The car now weighs 1250 kg (2756 lb).

GC8F (9/1998-9/1999)

The 1999MY WRX is introduced on September 1998. The power rating remains the same as the previous year's model, but the torque is increased to 34.5 kg·m (338 N·m) at 4000 rpm due to improvements on the engine design (the engine was dubbed as Boxer Phase II engine). The car now has a curb weight of 1270 kg (2800 lb). The WRX Type RA receives the same power upgrades and has a weight increase of 20 kg (44 lb) to 1210 kg (2668 lb).

GC8G (9/1999-9/2000)

The last version of the WRX is introduced on September 1999. There is no change in the mechanical specifications. Added features are newly-designed alloy wheels, color-coded mirrors and door handles, remote central locking, intermittent wipers with a timer and map lights. Red Mica had replaced Bright Red.

UK-spec Special Variants

"1.8GL" (1993)

Subaru imported six Type RS's, the development car that led to the stripped-out Type RA. For UK car certification reasons they were registered as 1.8GL's despite having big turbos attached to 2 litre engines. Three cars went to Prodrive; three were retained by Subaru UK and were subsequently sold.

Series McRae (June 1995)

200 cars in Mica Blue with 16" gold alloys were produced to celebrate Colin McRae's success and, in particular, winning the 1994 RAC Rally. He went on to take the driver's title and win Subaru their first WRC manufacturer's title in 1995. The cost was £22,999. GBP redirects here. ...

RB5 (1999)

Subaru Impreza RB5

To celebrate the return of British driver Richard Burns to the rally team in car number 5, a limited edition of 444 cars in "Steel Blue" (aka Cool Grey) was created. The basic £24,995 model had little more than cosmetic differences, but most had the WR Sport Performance Pack, an option consisting of a new ECU and exhaust for 240 PS (237 hp/177 kW) and 350 N·m (258 ft·lbf) torque. The price for the higher spec car was £27,000. [1]. There was also an optional Prodrive suspension pack that cost extra again.

In 2001, the Impreza line received a complete update. The chassis received a 120% increase in torsional stiffness. The version nomenclature was dropped from the name. To distinguish between the years, Japanese and other auto-enthusiasts often refer to the chassis as GDA (the WRX had an 'A' where as the STi had a 'B') revision A to G where G is the current (2007) version.

The WRX has received two styling updates. The exterior "bug eyed" styling was widely regarded as somewhat unattractive, so Subaru introduced a mild facelift (often called blob eyes or peanut eyes) of the front end in the 2002 Paris Auto Show. A third update was introduced in mid-2005, including the performance models, with the controversial "jet intake and wings" grille first debuted on the Subaru R1 keicar, along with new headlights (sometimes referred to as hawk eyes or pig nose and also "vag eye" due to the effect on the grille), taillights, and bumpers.

Japan-Spec

Rev. A (2001)

August 2000 brings the 2001MY WRX NB sedan. It has an EJ205 with AVCS coupled with an MHI TD04L turbocharger. The engine produces 250 PS (184 kW) at 6000 rpm with 34 kg·m (333 N·m) at 3600 rpm. The wheels are 16 inch in diameter. The car uses 2 pot/1 pot front and rear brakes. The front brake rotors are ventilated while the rear are solid disks. It has a torsen rear LSD and a 4.44 final drive ratio. The transmission has close-ratio gears unique to Subaru of Japan at that point in time. The car has a curb weight of 1340 kg (2954 lb). Turbo redirects here. ... Torsen traction, an automotive part adding differential, was invented by American Vernon Gleasman and manufactured by the Gleason Corporation. ...

Rev. B (2002)

The 2002MY WRX NB sedan debuts on September 2001. The mechanical specifications are similar to the previous year's model but the curb weight has been increased to 1350 kg (2976 lb).

Rev. C (2003)

The WRX NB-R sedan is released on November 2002. The power and torque ratings are the same as the previous year. The wheel diameters are increased to 17" in size. The rear brake rotor is changed to a ventilated disk, leaving the car to use only ventilated disks for braking. The car has 4 pot/2 pot front and rear brakes. The rear wing is on wing risers. The car now weighs 1361 kg (3000 lb).

Rev. D (2004)

The WRX line receives a body exterior update and an improved transmission.

Rev. E (2005)

The WRX WR-limited is introduced. The car receives an STI spoiler and an STI front chin. There is a WR-stickered titanium shift knob. The wheels are changed for STI, gold-colored Rays-sourced wheels.

Rev. F (2006)

The WRX has an option to receive the same spoiler as the WRX STI and receives gold 17" x 7" wheels. The WRX has a viscous rear LSD now.

Rev. G (2007)

The car is mechanically the same as the previous Japan-spec revision.

United States-spec

Rev. A (March 3 2001)

WRX's initial release date

Rev. B (2002)

North America receives its first Impreza WRX models. They are equipped with an EJ205 engine rated at 227 hp (169 kW) at 6000 rpm with 217 lb·ft (294 N·m) at 4000 rpm. Unlike the Japanese EJ205, the US-spec engine uses a Mitsubishi TD04-13T turbocharger unit. In stock form, it reaches a peak 13.5 psi of boost. The seats are the same as the basic J-spec Impreza. The wheels are cast 16” x 6.5” version of the J-spec WRX NB wheels while the brakes are 2-piston/1-piston front and rear with the front rotors being ventilated disks. 2002 WRXs came with brake duct plates that guided the air in the front bumper vent to the wheel well. The gear ratios are the standard export models, but the final drive is a 3.9:1 ratio. The rear LSD is a viscous coupling type. The steering rack has a ratio of 16.5:1. The 4 gear electronic automatic transmission (4EAT) WRXs have a Variable Torque Distribution AWD system instead of the conventional viscous coupling center differential. VTD employs an electronically controlled hydraulic transfer clutch and a planetary gear center differential to distribute power in a 45:55 split between the front and rear axles under normal circumstances. The VTD system uses multiple sensors to measure front and rear driveshaft speeds, throttle position and gear selection. Then it actively transfers power accordingly between the front and rear wheels for optimum traction and handling. The WRX weighs 3085 lb (1399 kg).

Rev. C (2003)

There are few changes from Rev. B. The gears are changed to RA-width gears (1 mm increase in size) to increase durability of the transmission. There is also a valve that prevents “drop-clutch” starts in an effort to reduce the number of shattered gear boxes from abusive AWD launching. The ignition ring is now illuminated with green lighting. Early 2003 WRXs had brake duct plates. At the end of calendar year 2002, the brake duct plates were no longer equipped on the WRXs. A shorter metal fuel pipe and longer connector hose were implemented under the intake manifold to avoid fuel leaks at freezing temperatures.

Rev. D (2004)

The WRX received the same Peter Stevens-designed face lift that rest of the Imprezas received. The WRX uses the same contoured seats as the 2004 US-spec WRX STI. The WRX is equipped with multi-phase valve struts to improve ride quality while retaining good handling. Tach is moved to center and speedo is on the right now.

Rev. E (2005)

The WRX receives an updated interior, body colour rocker panels, black painted headlamp bezels, and wheels that were previously seen on the base US-spec Legacy and a single-port exhaust. Some regular WRX models have an STI hood scoop which is much larger then other WRX scoops. The suspension has also received a few small updates to make handling more efficient compared to the 2004 model.

Note: Saab released its 9-2X Aero, from its 9-2X line, which is essentially a re-skinned Impreza WRX Wagon of the same model year. It is manufactured by Fuji Heavy Industries, Ltd. There is also the Saab 92, from the 1950s. ... A descendant of the Nakajima Aircraft Company (est. ...

Rev. F (2006)

2006-2007 Subaru WRX sedan (US)

2006-2007 Subaru WRX wagon (US)

For 2006 the Subaru Impreza WRX received a complete front-end re-design, boldly styled headlights with smoke-tinted lenses, a three-section mesh-type grill, and distinguished new tail lamp clusters. Three trims levels are available: WRX TR (Tuner Ready), WRX, and Limited. The car’s curb weight is 3140 lb (1424 kg) for the WRX TR, 3192 lb (1448 kg) for the WRX, and 3240 for the WRX Limited.

The biggest change was the 2.5-liter turbocharged intercooled EJ255 engine, producing 230 hp (172 kW) at 5600 rpm. It replaced the 2.0-liter EJ205 engine used since the WRX model's introduction. The larger-displacement engine produces 235 lb·ft (319 N·m) of peak torque at 3,600 rpm, compared to 217 lb·ft (294 N·m). at 4,000 rpm for the previous WRX. Performance was improved in all speed ranges, with greater emphasis on low-end and mid-range torque. The 2.5-liter WRX engine shares architecture and technology with the WRX STI engine, including Subaru Active Valve Control System (AVCS) variable valve timing technology and an Electronic Throttle Control system. The turbocharger remains the same unit as on the 2002-2005MY US-spec WRXs, but now only peaks at 11.6 psi of boost. The first gear in the transmission received dual-ring synchros to improve downshifts from 2nd to 1st.

2006 Impreza WRX models gained significant chassis and braking system enhancements. Aluminum front suspension lower L-arms reduce unsprung weight to enhance steering response. (The rear suspension gained forward aluminum lateral links in the 2005 model year.) The steering rack was updated for improved steering feel and the steering rack ratio has been changed to 15.0:1. On all WRX models, new 7-spoke 17 x 7-inch aluminum-alloy wheels replace the previous 5 spoke 16 x 6.5-inch wheels. Tires, likewise, are 215/45ZR17 versus 205/55R16 before. The more powerful brake system employs 11.5 in (292 mm) vented front discs and now uses four-piston calipers instead of the previous versions two-piston calipers. The rear brakes are all new, with 11.3 in (287 mm) ventilated discs replacing the previous 10.3 in (262 mm) solid discs, and two-piston calipers replacing single-piston calipers. Painted red and featuring the SUBARU name in white, the calipers also make a strong visual statement.

The horsepower and torque numbers are likely underrated, as shown by multiple independent dynamometer tests.^[2] This is further proven by further comparisons. If the 2005MY US-spec WRX had 217 lb·ft (294 N·m) of torque, then the 2006MY US-spec WRX's 235 lb·ft (319 N·m) should show a minimal amount of increase on the dynamometer. However, tests have shown that a 2006MY US-spec WRX puts out a higher peak torque rating than a 2005MY US-spec WRX with Stage 2 Cobb Tuning (turboback exhaust and engine control unit reflash).^[3] Hence the conclusion that the car is possibly underrated. A dynamometer, or dyno for short, is a machine used to measure torque and rotational speed (rpm) from which power produced by an engine, motor or other rotating prime mover can be calculated. ...

Rev. G (2007)

Ikuo Mori takes the place of Kyoji Takenaka as President and CEO of Fuji Heavy Industries.

As a cost-cutting effort, the WRX has its aluminum suspension reverted to steel-cast pieces. The WRX and Limited trim levels receive an auxiliary audio port next to the cigarette lighter and MP3 CD playback.

A rumor arose from cars101.com that in an effort to reduce torque load on the five speed manual transmission Subaru made the following changes to the gear ratios of the 5-speed manual transmission:

2007: 1st=3.454, 2nd=2.062, 3rd=1.448, 4th=0.880, 5th=0.780, with a 3.0 final drive

2006: 1st=3.454, 2nd=1.947, 3rd=1.366, 4th=0.972, 5th=0.738, with a 3.7 final drive

This information is entirely false. The 5-speed manual transmission and final drive ratios remain the same from 2006 to 2007. Furthermore, a 3.7 to 3.0 final drive ratio change would rather increase torque load on the transmission.^{[citation needed]} A manual transmission (also known as a stick shift, straight drive, or standard transmission) is a type of transmission used in automotive applications. ...

Due to complaints of slower acceleration in comparison to the GC-chassis WRX, the gear ratios and diff ratio are changed to the same specifications as the Japanese domestic market WRX to improve overtaking and in gear acceleration. The result is near identical first and second gear ratios to the GC, but with a noticeably shorter third, fourth and fifth gear.

Also added was a Suretrac limited slip rear differential. Japanese engineers claimed that drive would still be directed to the gripping wheel even if the other wheel was off the ground.

GC chassis comparison to the GD chassis

Pros

Subaru claims that the GD chassis is 148 percent and 82 percent stiffer in torsional and beam rigidity, respectively, than the GC chassis. This stiffness is primarily due to the addition of a steel "ring" which encircles the cabin at the B-pillar. While the stiffness was increased for passenger safety, it has the added benefit of providing more stability for motorsports events.

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 Dec. 2005 Firehouse magazine (a periodical written 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 accidents.

Cons

The GD chassis gains nearly 200 kg (441 lb) in weight over the GC chassis. Most of this weight comes 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.^{[citation needed]} The GC Imprezas were notable for being very lightweight despite having AWD. The WRX Type R STI Version VI using the GC chassis, at 1260 kg (2778 lb), was lighter than the competiting Mazda RX-7 type RZ (1270 kg (2800 lb)) and Honda NSX type S Zero (1270 kg). In this fashion, the GC chassis has a better advantage.

2008 Subaru Impreza WRX hatchback (North America)

The Impreza WRX gets a whole new redeisgn starting from mid-2007 as a 2008 model year. The engine used is still the EJ255. Peak power and torque as the same, but the peak power will output at 5200 rpm (400 rpm lower)and the peak torque delivery will be at 2800 rpm (800 rpm lower)with redline at 6500rpm. The 0-60mph time for the WRX is around 5.6- 5.8 seconds(depends on the source of information), like the predecessor, while decreasing the 50-70mph time due to the improved torque delivery. The transmission is similar to that of the previous models, only the ratios are slightly wider in the low gears with a final drive ratio of 3.9 instead of 3.7. The sedan version has a two exhaust outlets while the hatchback will have one exhaust outlet on the right. The car is based on a shortened Subaru Legacy platform. The front suspension uses a MacPherson strut setup while the rear is a new double wishbone suspension. The steering ratio will be 15:1. The hood is supported by hydraulic springs instead of a simple rod and hook mechanism. The interior has been updated to imitate the Subaru Tribeca SUV. A new chip computer with average fuel consumption is being introduced for the first time in the Impreza/WRX. The US-spec WRX reverts back to a 2-piston/1-piston sliding calipers (dropping the 4-piston/2-piston fixed caliper setup), but have grown by 0.1inch.in the front and 0.1-0.2inchin the rear with premium package. The calipers and rotor setup are the same found on the BL5-chassis US-spec Legacy 2.5GT and Spec B. The stock wheels are 17" x 7" on 205/50 R17 all season tires. The gas tank has grown from 15.9 gallons(60.2Liter) to 16.9 gal.(64Liter) The car's weight has decreased to 3142 lb (1425 kg) for the 5 speed manual and 3208 lb (1455 kg) for the 4 speed automatic. The Impreza WRX was sold to the public starting July 2007 as a 2008 model year car in Canada, and in the United States in October 2007. The 2008 Impreza WRC rally car is based on the hatch version of the car. Bluetooth functionality was expected, but is not present in the GPS-equipped September 2007 cars although the manual for the navigation unit contains a chapter on phone connectivity. The whole model range of the 2008 Impreza/WRX/STi does not come with sunroof/moonroof. Cars can come in a large variety of different body styles. ... A notchback full-size luxury sedan. ...

Subaru Impreza 2007 WRC

Subaru Rally Team revealed the new 2007 Impreza WRC Car on Friday 2nd March with just seven days before the Rally of Mexico. Petter Solberg and Chris Atkinson have big hopes for the new Impreza after their not-so-impressive 2006 season in which they could not even win a single rally. As the teams left their base in England heading towards what will hopefully be a competitive weekend for rally Mexico they released details of the 2007 Impreza that will be competing for the rest of the season. Petter Hollywood Solberg (born November 18, 1974 in Askim), from Spydeberg i Østfold, Norway, is a professional rally driver. ... Chris Atkinson born November 30, 1979 in the far South Coast town of Bega, New South Wales, Australia, is a professional rally driver. ...

From the outside the New Impreza doesn’t look that different. Most of the work has been carried out on improving the performance and creating a car with more balanced tyre wear. The team has worked with engineers and designers in Japan focusing on weight distribution, suspension and differential set ups and new dampers have been used to improve road holding.

The work on the new engine has been aimed at weight reduction. The work has included producing a new intercooler design with a turbo air inlet now going through the bonnet scoop. The FIA’s rules about aerodynamics have led to the removal of several apertures on the front and side of the bodywork which have been partially blanked off. The airflow under the bonnet now emerges through air exit holes on the side rather than in the middle of the bonnet.

The Impreza’s hydraulic control of the centre differential has been redesigned to improve its effectiveness and the exhaust has been moved to exit out of the rear bumper. The Subaru team has already started to design the '08 car but no decisions of when it will make its debut have been decided.

FIA

Currently only the higher powered version of the WRX, the WRX STI is homologated for Group N rallying. However, the S9 and newer models of the Impreza WRC car have a GDA chassis code. This fact signifies that the Impreza WRC cars are built off the WRX chassis rather than the STi chassis.
