Default New Impreza details

Images are linked from from impreza-net
http://www.impreza.gr.jp/masa/subaru.../peage001.html


The bottom right STi has all the factory optional items loaded including the BBS rims.

changes on WRX STi:
aside from obvious exterior and interior changes,
Engine has been modified extensively.


This is the exhaust manifold. It is equal length and note that it is 4-2 not 4-2-1. The turbo is bigger and it is "twin scroll turbo" The exhaust comes in from two pipes.


Internal is stronger and the TGV has been eliminated from the intake manifold.

This is my favorite pic

can't see the front!!

DCCD is optional on STi and standard on Spec-C
DCCD has auto mode this time.



Regular WRX gets smaller turbo for faster spool up.
The car is actually faster in 0-62mph by 0.5 sec. (about 6.5sec.)
It's got inverted shocks
front 4pot/rear 2pot combo
and 17 inch Euro WRX/NB-R/ex-B4 wheel

Thanks for the cool details!

BTW, since its the JDM model, is the redline still at 8000 RPMs? I can't tell from the picture.

All I can say right now is the differences in the engine department are nigh unbelieveable. That alone was fantastic -what happened with the suspension setup verges on pure magic.

The change to the new WRX/STi is not cosmetic - in many ways, this is a completely new car. STi called it a "level up". It's not. It's about 3 levels up.

Cheers,

Paul Hansen

Thanks for the info, guys. Too bad japancars.com doesn't have info for the WRX wagon. Also, I noticed that leather is not listed as an option for some reason. I'm getting it, and I know that I've seen it written in other places. Too bad I didn't know about the HID option though. Hooray for aftermarket!

HID has never been a standard item on Impreza in Japan. It is $2000 option. Also I have never seen Impreza with leather seats in Japan. There is Recaro bucket seat available from STi but not leather.

Damn, that's a lot of changes (even the wiper!). But even if you don't read Japanese, all you need to know is this

That can't be right... It says the WRX wagon comes with a 6-speed?? That'd be great if so, though!

Edit: Nevermind, need to read the whole page before posting.

The best new feature on STi to me is this

"When you turn on the ignition, the STi logo comes up and Tachometer revs up to its maximum rapidly and comes down" (according to Subaru release)

Some entertainment, huh?

This is big news. Subaru, until now, has always used a constant-pressure type turbocharger. In constant-pressure turbocharging, Subaru uses a relatively large volume uppipe to damp out the mass flow and pressure pulses so that the flow to the turbine is essentially steady. It appears the turbocharger used on the new STi is a pulse type turbocharger, which is specially designed so that much of the kinetic energy associated with the exhaust blowdown can be utilized. Relatively small volume header pipes are used. The small cross section maintains the desired high gas velocity and concomitant kinetic energy to the turbine inlet. If all four cylinders fed into a single pipe, the separation between the pulses (180 crank-angle-degrees) would be too tight and they would interfere with each other. To solve that, the four cylinders feed into two pipes and the turbocharger has a divided turbine inlet with the division maintained throughout the turbine housing all the way to the end of the nozzle section. This keeps the cylinder exhaust events within each half of the divided housing spaced apart 360 crank-angle-degrees. The net benefit of pulse turbocharging is faster spool up and a steeper boost curve. Pulse turbocharging is rarely seen in gasoline powered cars but I do know that the Mitsubishi Lancer rally car uses one.

According to the Subaru release, STi now have 40.2kg m Torque...that means 290.8lb ft (if my conversion is right...). That's a lot of Torque, isn't it?

Also, it is first time in Subaru history, STi now have Electronically controlled AWD on stick shift model (6MT) (Driver's controlled Center diff with "AutoMode") .

Is this just the gauges moving, or the computer redlining the engine upon startup? Either way, I could do without.

That instrument cluster is WAY WAY cool!! If you open up your own WRX instrument panel, you'll see the trademark NS, which stands for NipponSeike. What does NS make? Defi gauges. And anyone w/Defi gauges will tell you that when you start the car up, the needles do an automatic full sweep for system check. Also Defi has that black out gauges that some vendors here are selling. So apparently they made it to the OEM line. Very cool. (so no, the engine itself isn't revving, just the gauge self check).

I wonder if the new header/pulsating turbo system can be used on our cars?

Looks like STi is really going after the evos this time

I hope that I'm not sick that I didn't wait for an STi. As for the gauge cluster, I wonder how visible those are in the daylight. Anybody with experience using the black out dephi gauges?

The "black out" gauges are similar to Optitron gauges, which have been offered in Japan and Europe in various brands for a couple years now. They are basically back lit behind the numbers, rather than lit from in front. The numbers and markers are nearly transparent, and thus can't be seen with no power. But when the power is on, it's brighter than normal gauges.

290 lb ft of torque. Wowee zowee!

Blah. All that lit-up gauge crap is just wasting precious engine power

DCCD, is that the adjustable center diff?

AHHHH!!!!! I CAN'T TAKE THE SPECULATION ANYMORE!!!!! I WANT ONE, WANT IT NOW!!! gimme, gimme, gimme, gimme....

<whew> Sorry, but damn that looks great! I knew there were a lot of differences other than just hp, but I never realized there were that many!

Now I'm going to have to reconsider whether or not I'm getting one.
