I'm not questioning you, but I'm genuinely interested to see how the rest of their test/review varies from other magazines. That's pretty cool though that it still is only one gear change for the wrx.

Sure thing, no problem:

Here are the stats from their test:

C/D TEST RESULTS:
Zero to 60 mph: 4.8 sec
Zero to 100 mph: 13.1 sec
Zero to 130 mph: 25.3 sec
Rolling start, 5-60 mph: 6.3 sec
Top gear, 30-50 mph: 12.1 sec
Top gear, 50-70 mph: 7.9 sec
Standing ¼-mile: 13.6 sec @ 102 mph
Top speed (gov ltd, mfr's claim): 144 mph
Braking, 70-0 mph: 160 ft
Roadholding, 300-ft-dia skidpad: 0.95 g

The WRX is very conservatively tuned. it would trump the stock STI with a reflash I am sure.

I am taking delivery on a 2015 WRX hopefully this Fri. While Road and Track did 14 consecutive clutch dumps from redline to attain the fastest 0-60 times on Subaru's engineers insistence, that only proves the transmission is tough.

Wait until Cobb get's their AP tunes up and going. Then we will see what it can do.

I decided on the WRX over the STI not due to price, but the fuel economy, more modern and less peaky engine. This will be my daily driver and likely never see a track, so it made sense. When you get the revs up high, the STI is clearly more powerful, but for daily driving the WRX should feel every bit as fast for most people. And aside from a not quite as tight steering gear, it feels just as tight in the handling dept with the new artificial torque vectoring which does the job of the mechanical LSD's. The Brembos are nice, but again only really useful in a track environment. I dont need to adjust the torque distribution to drive to and from work either.

In another lifetime I would have loved to go to lapping days regularly, but in reality I just don't see that happening. Plus, the wing is pure rice IMHO.

All the write ups say they did a good job of tightening up the handling compared to the previous generation WRX.

It looks that way. One tuner was able to achieve 50hp and 35ft lbs of torque on a tune alone (meaning stage one with no other bolt ons).

Love getting Nudered. Coed skinny dipping is the best!

I am pretty sure that the WRX & Foerster Run lower compression allowing them to run lower quality gas.

12.1:1 i thought, but yes.

STi will always be faster and a better buy then the WRX. Funny how WRX owners always try to out class the STi, not happening. And this is coming from a WRX owner. EJ257 is not a bad engine, it has great power and tq even if it is from 2004. It has improve since its introduction 10 years ago. There is to much difference from the WRX and STi.

2015 WRX is a different car compared to the previous WRX in every way.
What exactly is different in the 2015 STI compared to the 2014?

So that generalization from perceptions past owners had doesn't really hold any weight.

Off the top of my head the differences between the 14 STI and 15 are:
- Much stiffer chassis
- More bracing
- Stiffer springs
- Larger sways
- Much tighter steering rack
- Torque vectoring
- Upgraded interior
- The changed the throttle mapping in the 15, and supposedly it is more responsive

I am sure there is more. I think the big change is going to be the handling and suspension. Subaru really focused on that with this car and it shows if you drive one. They feel very different from the previous car.

So the only reall difference between the WRX and the STI is the fa20 and the EJ25.... :p

No, I thought you were asking about the 14 STI and 15 STI.

15 Sti and 15 WRX (outside of engine) are pretty typical of previous years:
- Better gearbox in the STI that can most likely hold down more power
- Stiffer suspension
- 6 way adjustable center differential
- Brembo braks
- 18" wheels and wider/griper tires
- Tighter steering rack
- More standard amenties
etc, etc.

Actually the WRX has a higher compression ratio than the STI because it has a newer engine that doesn't suck. However 10.6 is still quite low, the typical 10.5-11 range port injected engine these days runs fine on 87 naturally aspirated, and this engine being direct injected should be able to run some decent amount of boost on 87 without knocking. You just don't get full power, obviously.

The comparison was the twins having to run 93 vs 87 like the wrx, not the wrx vs the sti.
