2015 Subaru WRX: The Street-Legal Rally Car Gets Sharper

http://www.autoblog.com/2013/12/16/2015-subaru-wrx-review-first-drive/?ncid=edlinkusauto00000017&ts=1387215748

This particular article has some more talk of how Subaru decided to ax the hatch model:

What’s super sad, though, is that people won’t necessarily be buying the new model for its functionality, either – the hatchback bodystyle is dead, and Subaru has no plans to resurrect it. When asked about the decision to kill the five-door, the company’s engineers said that, basically, it came down to money – spend it on making two bodystyles, or pump that cash into the chassis and powertrain development. Subaru would rather have one great-driving car than two that are simply good. I get that logic, but let’s just say I don’t want to be the one to have to explain it to the 50-percent of previous WRX buyers who opted for the more functional, better-looking five-door.

And here’s another paragraph that caught my eye (due to all the whining that the car is ugly):

The WRX has never been a particularly pretty thing, and the new model does nothing to break that trend, despite its decidedly hot concept car roots. Then again, you don’t have to look at the sheet metal while you’re driving (I’ve used this same logic with prior versions of the car), and even Subaru’s executives know that people aren’t buying this thing for its glamor.

Overall, a good review.

2015 Subaru WRX Reviews

All of the reviews are pretty good, considering that these are still pre-production cars.  At least one magazine said that a full review would be done relatively soon, so we should have an in-depth review to read, “relatively soon.”

At least one mag also tested the car in the 0-60 and quarter mile:

In straight-line testing, our 3330-pound tester, a top-of-the-line Limited with the six-speed manual, proved slower than the 2013 WRX Special Edition (4.7 seconds, 13.5 seconds at 100.0 mph) and the 2012 Mitsubishi Lancer Evolution MR (5.1 seconds, 13.8 seconds at 100.0 mph), with 0 to 60 mph coming in 5.5 seconds and the quarter mile in 14.0 seconds at 98.1 mph. Quick, for sure, and quicker than the 3193-pound 252-horsepower Ford Focus ST (5.9 seconds, 14.6 seconds at 95.9 mph), but well off the times of the 3195-pound WRX SE and the 3631-pound Evo MR. What’s with the weight gain? Chalk it up to additional safety structures and new equipment such as a power moonroof and harman/kardon audio. The silver lining: road test editor Scott Mortara noted that a better launch could easily drop the times a couple tenths, and in our handling and braking tests, the WRX flat-out exceled. Max lateral acceleration registered at 0.96 g, a level of adhesion that matches the Evo MR and easily outgrips the WRX SE (0.92). Figure eight? A speedy run of 25.3 seconds – 0.2 second behind the Evo but 0.3 ahead of the SE.

There’s only a 60-lb weight gain between the old and new WRX…that does not account for the huge discrepancy in the 0-60 and quarter mile, though.  The 2015 will never be as fast as that 2013 WRX SE they tested, mainly because the 2013 was equipped with a 5-sp manual, while all 2015s will be equipped with either a CVT or a 6-sp manual.  Yes, that means the 2015 now has an extra shift point, just as the GR/GV STIs did…remember everyone stating that the WRX was quicker like it was some magic sauce that Subaru had applied to their go-fast concoction?  Well, the reason why it was faster was because the STI has closer-ratio gears…a driver has to shift the STI before the end of the 0-60 and quarter mile, which means it’s going to finish both events slower than the 2013 WRX.

Also, look at the other data…the max lateral acceleration and figure eight results…ahead of the 2013 SE  in both cases and ahead of the Evo in one.  That’s not bad at all.

The next Mitsubishi Lancer Evo – Hybrid + AWD

The next #Mitsubishi Lancer #Evo will be a plug-in hybrid, all-wheel drive, technological monster.

2015 Subaru WRX (Sound bite)

 

No more rumble.  2015 WRXs will use equal length headers, which are required for use with the twin scroll turbocharger.  I’m not sure if this will be the case with the 2015 STI (more than likely)…that’s gonna suck!

Another note:  the car in the video is the CVT version (like you can’t tell when watching…hahah).

Cobb Tuning – Researching AP v3 for Subaru STI

So, I’m conducting research on the Cobb AP just so I can make an informed decision on if this would be a good idea for my car.  The latest version of the AccessPort is expensive ($650), but the v3 offers a lot more functionality than the v2, so this may be what I’ll get.

In today’s research (this will take awhile), I saw the following:

http://www.cobbtuning.com/Dyno-Database-s/70119.htm, then select “Han Wu”

Summary:

This guy already has a rather strong STI (248HP/254TQ at the wheels).  When Stage 1 OTS was applied, the dyno read 269HP/319TQ).  From there, he got a protune while still at Stage 1, netting 276HP/327TQ.

If you click on all three dyno runs, you can see the differences between the three (there will be six graphs).  In particular, look at the stock and the Stage 1 OTS graphs.  Two things are apparent:  1.  There are a several big dips in both the HP and torque graphs on the stock dyno run; 2.  There are huge gains in the OTS map (21HP and 64TQ peak).  The last set of graphs looks to be where the owner decides to go Stage 1 protune (at 18.5 psi), where a few more HP and TQ are squeezed out.

The dyno session started at 9:30AM and ended at 10:11AM (granted, the work wasn’t much, as they went from stock to S1 OTS then protuned off of that).  IMO, that’s a significant gain and the session probably costed $300 (not sure where the tune was done).

PTuning is near me (in Manassas, VA), and I’m pretty sure they do protuning…I’ll check their rates.  I’ll also check their site to see their pricing on a Cobb AP and what they charge for a tune.

Cold Air Intakes by Nameless Performance

 Nameless Performance Cold Air Intakes for 2008+ WRX/STIs, coming January 2014.

 

 

 

 

After seeing this FB post, I’ve decided to purchase a Cobb AP and this intake (provided it is reasonably priced, ie $200 or so).  I’m actually still on the fence about the AP purchase, but looking at that FB post and the dyno chart posted by Nameless, the gains are really strong (9HP and 34TQ, peak measurements), you can’t really argue with that.  And Nameless even posted a chart awhile back that showed similar gains with just the damned axleback…crazy.  Add the Nameless axleback, the intake, and a safe but good protune, and I’d be close to 300TQ and maybe 260HP.  And I suppose if I get in over my head (I’ve done the modding game before…after awhile, it got tiresome, and that was before my kids arrived), I can always remove the bolt-ons and revert to an OTS (or run stage 1 without mods & with safe protone, which would still give me gains).

RRE Tuning with STIs/WRXs

A 2013 Subaru WRX. BONE STOCK. The owner is looking for something more reliable and responsive than the stock tune.  In the same post, a 2005 STI was also tuned (or retuned):
