The new five-door model features not only a greatly refined engine and suspension but new mechanisms such as the multi-mode Driver’s Control Center Differential (DCCD) and multi-mode Vehicle Dynamics Control (VDC). Also, the Subaru Dynamic Chassis Control Concept (Subaru DC3) has been further developed for the WRX STI in order to maximize performance and driving pleasure and to ensure high levels of driver satisfaction through total control of the vehicle.

The vehicle’s interior and exterior design expresses sophistication and refined functionality. The widened body flares give an irresistible presence, integrating function and beauty, while the interior design stresses high quality and a sporty image. In addition, the Impreza WRX STI features advancements in the areas of environment, safety, and comfort, all of which match FHI’s goal of delivering exceptional performance and enjoyable and dependable drivability with environmental considerations in all Subarus.

The first-generation WRX STI model was based on the first Impreza WRX and was developed by Subaru Tecnica International (STI), an FHI subsidiary specialized in motorsports activities. Sin Sin ce its introduction in 1994, the WRX STI has established a solid reputation as a high-performance sports model. In the FIA World Rally Championship (WRC) that requires participants to compete with production-based models, Subaru WRX Subaru WRX STI models have proven their credentials by bringing Subaru three consecutive Manufacturers’ championship titles from 1995 to 1997. In this context, FHI plans to submit a Group N homologation application effective as of January 1, 2008 for the new WRX STI to FIA.

The introduction of the new WRX STI has completed the full lineup of the Impreza series in Japan. The Impreza 15S, 20S and S-GT models have been available since June 2007, each offering individual strengths in performance and comfort.


Design

Styled around the concept of “Pure Form for Driving”, the widened body flares accentuate the 5-door body taken from the new Impreza. A deep-set character line, running along the side from the front bumper to the rear end, and a pronounced edge shape reflects light and shadows and gives the car a different look depending on the time of day. While retaining a consistent flow from front to rear bumper, the front and back fenders are prominently projected, creating a distinctive identity and gives the WRX a unique road presence.

Aerodynamically improved body styling with a large rear spoiler optimizes the balance between the front and the rear quarter panels by reducing wind resistance. An aerodynamically curved form from the front bumper to the front fenders helps minimize lift forces and contributes to maintaining vehicle stability at high speeds. Engine compartment ventilation is provided on both sides of the front bumper and along the rear edges of the fenders.

The strong front grille employs a sharp wing shape with metallic mesh, suggesting the car’s inherent sportiness. The rear garnish is painted in the body color, enhancing the widened body shape. The rear edges of the front fenders are embellished with STI logo plated in cherry red.

The muffler comes with twin dual-tail pipes. Eye-catching 18-inch aluminum-cast wheels, distinguished by their five spokes and highlighted by dark-tone high-luster paint, are standard. These wheels enhance the vehicle’s bold and commanding presence while expressing high quality and streamlined beauty. BBS-brand cast wheels with spokes and sharp lines are also available as an option.

Seven exterior colors are available: Obsidian black pearl; pure white; spark sliver metallic; dark gray metallic; lightning red; midnight blue pearl (only for the WRX STI); WR blue mica.

Interior design

The interior is finished in black and silver to highlight its streamlined design, as well as to create an impression of elegance and sportiness. Dynamic designs with decorative insets in the center panels and door trim express roominess in the cabin. The vehicle information display, which constantly shows outside temperature, average mileage and time, as well as a navigation screen and audio display, are placed nearer the top of the dashboard for improved visibility and functionality.

The front bucket seats use a combination of Alcantara fabric and leather and are designed to offer easy access into and out of the vehicle and to hold the driver and passenger in comfortably and securely. Jointly developed by RECARO, custom bucket seats are also available as a manufacturer’s option. The RECARO seats offer fuller side support and excel in maintaining a comfortable position for sporty driving. Their height adjustment enables the further lowering of the hip point setting in the seats.

Power tilt and telescopic steering comes with a three-spoke genuine leather wheel embossed with the STI logo in its center. The instrument panel combines three meters, a tachometer between a speedometer and fuel gauge, in a single module illuminated in red. Each meter’s dial is colored cherry red, the STI brand color, emphasizing a quality feel and sportiness. When the ignition key is turned on, the needles of the three meters swing up to their maximums and quickly fall back to their original positions, imparting a boost of excitement for the driver. The meter module also comes with a REV Indicator, DCCD Torque Indicator, and Shift-up Indicator. In addition, red LED lights are used for interior door step lights, and they are also provided for the console tray. The center console is embellished with the STI logo, which illuminates when the car’s headlights are on.

Packaging

An extended wheelbase and widened track provide optimal dimensions for the new model to ensure its outstanding driving stability and straight-line maneuverability. (The wheelbase is wider by 85 mm, the front track is 40 mm wider, and the rear track is 45 mm wider, than the previous model.) The 5-door body style excels in balancing lift forces in the front and desirable downward forces in the rear, achieving optimal aerodynamic characteristics.

Shortening of the front and rear overhangs has reduced yaw moments of inertia, and enabled highly stable handling, while interior roominess has been preserved. The body structure has been enhanced for improved performance and upgraded specifications. However, the gross weight has remained nearly the same as in the previous model through streamlined body construction.


Powertrain

An electronically controlled throttle enables finely adjusted control of the 2.0-litre turbo Boxer engine and ensures acceleration that is linearly responsive to pedal movement. The Dual Active Valve Control System (Dual AVCS) hydraulically controls timing in both the intake and exhaust valves, which helps improve low-end torque while providing a strong power boost at high rotations. Dual AVCS also increases combustion efficiency, thereby reducing exhaust emissions. Changes made in the intake and exhaust ports promote smoother air in- and outflow, contribute to enhancing power output, and improve combustion efficiency, which reduces emissions and improves fuel mileage. In addition, changes in the shape of the turbocharger compressor have increased the efficiency of the air intake and enabled more responsive and smoother acceleration.

Also, the layout of the exhaust pipes greatly facilitate overall air outflow by canceling interference and increasing airflow between the exhaust port and the turbo charger to deliver optimal torque and engine response at various speeds.

Subaru Impreza WRX STI

A tumble generated valve (TGV) has been installed in the intake manifold, boosting combustion efficiency by controlling the intake flow. It improves efficiency particularly at the time of engine ignition. Also adopted is a secondary air system that forces air into the exhaust port to burn out any gasoline remaining in it. The system helps eliminate harmful substances when the powertrain is still cool, and it promotes early activation of a catalytic converter.

The muffler is placed horizontally, which lowers resistance in the exhaust flow, results in improved noise cancellation, and contributes to smooth power output.

Transmission

A 6-speed manual transmission, Subaru’s own development, has been further perfected for faster, more accurate and responsive shifts. Friction is substantially reduced through the adoption of a triple-cone synchromesh in the first gear and design changes in the shift sleeves.

Drivetrain

The front differential gear adopts a torque-sensitive LSD (limited slip differential) that excels in response to input torque; the rear differential employs the Torsen LSD that supports distribution of torque. The SI (SUBARU Intelligent)-Drive system offers three different modes of driving for the driver to enjoy: Intelligent; Sport; and Sport Sharp. For example, when a driver continues to heavily depress the accelerator pedal in the Intelligent mode, engine output is automatically boosted to the level of maximum torque.

The multi-mode Driver’s Control Center Differential (DCCD) enables the driver to choose from different modes of control for the center differential. This feature allows the driver to enjoy handling and maneuvering as he desires, and it provides high levels of vehicle straight-line stability unique to the AWD configuration. The multi-mode Vehicle Dynamics Control (VDC) also provides three different modes that the driver can choose from to experience a wider range of driving enjoyment, while always maintaining the safety features of VDC.

Chassis

The WRX STI boasts a state-of-the-art chassis design that reflects the Subaru DC3. Equipped with a strut-type front suspension and the newly designed double-wishbone rear suspension, and combined with its widened track, this model achieves outstanding cornering stability. Optimized suspension geometry settings with adjusted camber angles have made substantial improvements in road-hugging traction and riding comfort. Aluminum cast lower arms and a stabilizer bar in the front suspension help raise torsional and rolling rigidity, providing accurate response in steering. In the rear suspension, suspension links are attached to the body through the sub-frame, which enhances riding comfort and further lowers noise levels.

The Boxer engine is mounted lower on the chassis, further advancing vehicle stability already ensured by its low center of gravity: 22 mm lower at the front end of the engine, compared to the previous model.

The Brembo-made ventilated disk brake system employs an ultra-low expansion brake hose and tie rods for the brake booster. The brake system, coupled with the SuperSports ABS (antilock brake system) with EBD (electronic brake distribution), processes information fed from the G sensor, steering angle sensor, yaw rate sensor, and pressure sensor to deliver steady braking and control. It also works with the DCCD to ensure accurate braking on all four wheels independently, while minimizing deviations from the driver’s intended path. Bridgestone RE050A (245/40R18) tires are standard.
The hill-start assist function maintains the braking function one second after the brake pedal is released in case of starting a car on a hilly road.

Body construction

The WRX STI uses an advanced form of Subaru’s legendary and proprietary Ring-Shaped Reinforcement Frame Body Structure, reinforcing each pillar with frames that circle around the body in a ring shape. Reinforcements are now provided to connect firmly between the lower part of the front pillar and upper frames, increasing the strength of the strut attachment onto the body frame. Reinforcements are also added to the upper part of the opening of the rear gate.

Through streamlined body construction and the extensive use of high-tensile steel, including 590 MPa–level steel for major body frames, the new model has achieved both high body rigidity and a weight reduction of 11 kg.

Safety

Advancing the Ring-Shaped Reinforcement Frame Body Structure, the new WRX STI has realized high levels of safety and crash worthiness through effectively absorbing and dispersing crash impact in frontal, side, or rear impact crashes. The hood, for example, is specifically designed to disperse frontal impact. The new model boasts low-impact features for pedestrians and other vehicles in collisions.

Subaru Impreza WRX STI

All models are equipped with dual SRS airbags, side SRS airbags and curtain airbags, as well as 3-point seat belts in the rear seats. A collapsible brake pedal is available on all models to reduce the risk of foot injuries in accidents.

Seems I was wrong about one thing on one of the EVO pages. This version does have understeer. So much for Subarus legendary vehicle control. Understeer with all wheel drive, what the hell is happening to Subaru. Thank God I still have faith in four wheel drive cars , thanks to the EVO and GT-R.

Badest, one of your comments on the EVO pages was "now this is one hot evo!". Was that you insulting it?

Most of you are throwing specs from all around. Have any of you ever driven either of those cars (except for one guy said he had test drive both).

I run a 310hp 2000 model WRX. Modified obviously with stronger piston rings and all that so it can basically handle 500hp. And if the handling wasn’t good enough, I also installed adjustable shocks lowering the car by 2 inches( the firm shocks wear out rather quickly). And for cheaper, more power, a shot of NOS delivering an extra 75hp(yet to be tested).

Problem, none except the gear shift is too bloody long but most WRXs have the same problem. Mine I rectified with a short shifter kit.

I have never really driven an EVO so I can’t rightly say but judging by the way everyone reacts to its name, it is something. From what I read on this site, the EVO is more advanced and one of the best(if not the) handling cars out there.

Both are great cars, so it is like comparing an apple to an apple which is not always a good thing.

My opinion-whether you drive a Ferrari or a Toyota Prius, you should enjoy it.

and how does the old evo XIII in 2004 go from running a 4.8 0-60 to a 5.2 now... i wanna see some specs.. but anyways i’m impressed with the new sti... too bad its not a sedan

one drawback to this car... i’m not the biggest fan of hatchbacks... other than that it seems like a great car. but both the evo and the sti are both great cars... guess its gonna come down to pricing

the evo is a piece of garbage crap i wud spit on that car before i ever offer it any respect....waste of money an time, that lil half steppin 5.2 secs to 60 makin wanna be rally car.....as i said piece of garbage the STI does it in less than 4.6 secs get ya’ll facts strait children

lol miss awd still talkin crap ah my the evo speed tv an top gear tested it an admitted that the new sti is way better shut your trap man STI is the best of the best...mitsu is jus the 2nd place runner up an u kno wat they say bout 2nd place is jus another name for the 1st loser!!

i would buy the evo over the sti no doubt

"haha you boys are tossers"

When someone is acting (writing) like a kid, why is wrong to call him or her as such? From where we all stand, it could very well be 11 year old on the other side of the keyboard! Especially from the stuff that is written!

hmm.. MrAwd actually dared to come back and comment. would not be surprised if badest had something to say bout that. However from what i have read it is clear that Mr awd is a subaru freak and will do anything to defend it. dont appreciate u calling people kids tho.

I love the fenders

What do they say about those who end up laughing at the end...whatever it is but not that good for you stubborn kids who wouldn’t listen! If you payed attention to the finally real result (latest issue of the Car & Driver would be a good place to start) with real USDM versions of the STI and EVO, then you would be crying your eyes off. Well, at least that is how much you seemed attached to the performance of something imaginary.

STI could even beat VW R32, so adding EVO X to the picture is just too much. Besides things that we knew about lousy handling and lack of feel that this car has. There are also acceleration numbers that can’t even match the 200 lb car that make less HP. And that goes for both 0-60 and 1/4 mile drag strip.

Well, technology is advancing so you either chose to stay with it or you can keep dreaming about the STI!

WOW this dude is a true loser who doesn’t know when to quit an who is he to be sayin i ain know much english lang, yo dude you don’t know me or anything bout me so i suggest you calm down son before i get in this but i do know somethings bout you jus by wat u bin goin on with, you don’t know when to hush up you talk a load of junk and lastly your insults really need to be worked on OVER-TIME since u got here you bin gettin kicked around by badest lol its bin hilarious jus reading it

an shooting blanks? er?!! who the hell says that gee i had no idea i was talkin to a 80 year old gran pa.....well ok sorry gramps for disturbin you and makin you all cranky an wat not.....i guess you crippled back an weak knees bin buggin you but hey don’t hate on me cuz my brain still works perfectly an i don’t have amnesia like you or that i wind up talkin bout sumthin that i don’t have a clue to wat i am sayin LOL yeah nice try but really your a lame

child since u came here runnin on like some bored house wive i’ve bin laughin at you.....and your the one who never had an option other than flappin ya gums you really give the male race a bad rep dred i trully pity you an hey if u don’t believe me that ur being pathetic lil squirt look at that guy ’thereal’ comments even he bin laughin at you face it kid you need a day job cuz obviously you have no life!! LMAO thanx for tryin but sorry you failed to make a statement once again......i dun gave u advice get sum punchlines cuz talkin like a girl obviously isn’t goin to work

You kids are riot!! It is fun to come here and steer some of your anger. It is becoming more obvious that you are hitting the wall here since calling me names is just saying I ran out of options and that is all I can do to satisfy myself!

Feel kind of sorry to get you upset so much that you stop to even talk about the cars, but rather directed all that hate of yours toward me in the attempt to insult me in here. Please, go back to your regular routine, take your s, and don’t let some strangers spin you up so much that you loose it completelly. If you have something to talk about the cars here please do so, but it is getting old to see you just shot blanks!

Holy**** that jus got killed again!! yo dude jus give up man you ain ga win this one you jus makin yaself look more like a idiot every time you write sumthing lol yo badest is like the papoose of this website spittin mad punchlines

yo face it CHILD you don’t know wat u are talkin bout you have no factual info wat so ever to bak ur ludicris ideas an ur insults are preschool level an lets face it YOU JUST PLAIN go an read a book an build up some of that infants vocab that you have.....the miami dolphins got more ego than this guy an i guess they wud pose a greater threat than you ever cud LOL. i ga give you sum advice since i feel sorry for you; step ya game up rework ya lil game plan an come back with sum decent punchlines cuz really its pathetic hopefully you’ll be a better challenge next time you respond to me

You kids are either all gone to the same school where they didn’t teach you much of the English language so you have hard time understanding the words that where written or this is just the same guy who creates lots of accounts in here so he will make himself look a bit more convincing... Either way you are so full of it and then some!

To claim to know anything about those cars without a chance to drive them and even talk crap about the guys who actually did drive them is beyond stupid. But, you managed to amaze me here since you actually toped that stupidity with even bigger one. You managed to use the same numbers from the guys you called clueless and the same guys that just trashed your bellowed STI by saying that is plain boring car to drive and even have build in understeer so the driver would have a clue when it is too much for a poor car (or a poor driver) to be pushed just like it is done for the base Hunday or Kia. They did say that steering has a bit of a better feel to it, but still far from the EVOs telepathic abilities through the corners.

You see you could have a car made to do one or two things well, but in the real world that requires those two things and several others you are still at the bottom and I know that hurts a lot. Being a full second behind on just a short 1 mile track is pathetic. To go through that track car needs to be able to accelerate, break, turns, and still leave confidence for the driver so he or she can do it again. You can take a top fuel car and bring it on the road and it will just be able to go straight without any chance to do anything else. But all of that is too much for you kids to understand, so I will stop at this for now.

Have a good one and don’t forget those s!

yeah thereal you right that is sad an to also mention how "awful" this evo is my ’93 supra, which is pretty old did 0-60 when it was still stock in about 5 secs flat and a 1/4 mile in 13.1 secs even an old supra does better performance than this new evo talk about pathetic i don’t think anyone can bring a greater insult than that and ppl say time has made the evo better ha!! the truth is in the performance an to be honest this vehicle has none.....infact i wud take everything off my supra let it go back to how it was stock an i wud go an race one of them an laugh in the drivers face when i humiliate him in his cheap worthless ricer whip
