2015 Subaru WRX STI Gets Trick Torque Vectoring

2015 Subaru WRX STI Gets Trick Torque Vectoring

Subaru has just taken the wraps off of the 2015 WRX STI and it doesn’t disappoint.

Starting on the outside, the new STI features a weight reducing aluminum hood that of course is equipped with a functional hood scoop feeding air to a top mounted intercooler. Narrower headlights than found on regular Imprezas adorn the front of the WRX STI with standard LED low-beam headlights. In all, the WRX STI features a unique hood, fenders, doors, quarter panels, bumpers, headlights and taillight clusters to separate the STI form both the Impreza and the WRX. Of course, a massive rear wing is still available.

Power will come from the same 2.5-liter turbocharged four-cylinder boxer engine developing the same 305 hp and 290 lb-ft of torque. As well, a six-speed manual will be the only transmission available. But don’t write the STI off as a mechanical carry-over just yet; the suspension and chassis have significantly changed.


Driver Adjustable

The WRX STI will include a 13.0:1 steering ratio that enables 2.5 turns lock-to-lock which is much quicker than the regular WRX’s 14.5:1 ratio and 2.8 turns lock-to-lock. The STI will continue to use an inverted-strut front suspension system with aluminum front lower L-arms to help save weight. 18-inch wheels wearing 245/40R18 summer performance tires are standard on all STIs while the Launch Edition and Limited models will come with obligatory BBS aluminum-alloy wheels.2015-Subaru-WRX-STi-spoiler.jpg

Subaru’s Intelligent Drive (SI-DRIVE) powertrain management system will allow the driver to select one of three modes, “Intelligent,” “Sport” and “Sport Sharp,” to change the engine control module and throttle response. As should be expected, the STI retains the Multi-Mode Driver Controlled Center Differential (DCCD) that splits power 41:59 front to rear and can be set in three automatic modes or one of six manual modes. A mechanical limited-slip type center differential will alter the torque split between the front and rear wheels depending on the situation. Thankfully, the 2015 STI comes with two more mechanical differentials as well; a helical-type limited-slip up front and a Torsen in the rear.

2015-Subaru-WRX-STI-grille.jpgFor the first time on an STI, active torque vectoring will be included, but sadly relies on brake applications to the inside front wheel to improve cornering ability. The good news is, the system includes three settings: “VDC Normal,” “Traction” and “Off.” In the off mode the active torque vectoring will be completely disabled and won’t interfere unlike a similar system found on the Ford Focus ST.

Inside, the new WRX STI has become more premium offering a harman/kardon audio system, dual zone climate control and Alcantara seating surfaces with red and black leather bolsters and red stitching. Most noticeable inside however is the new flat-bottom steering wheel.


Launch Edition

To mark the beginning of the new model, 1,000 special “Launch Edition” WRX STIs will be created all painted in traditional World Rally Blue Pearl. The interiors will feature unique trim with blue highlights, a STI short-throw shifter and keyless start. And, like any good STI, gold-painted BBS alloy wheels are part of this package as well.

    The rear wing has to go. I would have expected Subaru to have sculpted it into a more appealing feature like other manufactures have done.

  • Robert Viehweger

    It’s shaped to fit the aerodynamics of the car. It’s not just a piece of plastic they dropped on the back like a high school kid in a Civic. Function over form works with a little thing like downforce. I’ve driven wingless STi’s at high speeds, and it’s a bit too squirrely without it.

  • DoctorFeelgoodMD

    The 2015 Z06 rear is more like it and it works too. And yes, it looks like a high school kids reenactment of Fast and Furious. Remember, most STI’s are run on asphalt and not in a off-road application. The way they drove the STI on the vid (above) would put so many stone chips in the vehicle is all for show anyway just like most SUV’s with 4 wheel drive never see the dirt but once or twice in most cases. Regardless, Subaru fails terribly with that silly looking wing. However, I like everything else including the new front end and rear diffuser.

  • Dan Miles

    The wing is a badge of honor on the Sti. You obviously dont own one or you would understand.

  • Anthony

    Yea I love my STI’s wing it has a unique look and for all the people complaining about it jus don’t buy it and move on you complaining isn’t going to solve a thing

  • SSXT


  • Rick

    This looks like a child’s attempt to recreate the concept version we saw at the auto show. How sad.

  • Ken

    Pretty disappointing that the engine will be a straight carryover from the 2004 motor. It will be 11 years old when the 2015 models come out. At least the new WRX gets the 2.0L DI turbo 4.

  • Bill

    Not really a carry over from 2004. 2004-2007 STIs only had variable intake cam control. It is more of a carry over from 2008 where it incorporates variable intake and exhaust cam control. Still becoming an older engine and agreed, still disappointing.

  • Ken

    It is the same motor with variable cam timing on an additional cam, hardly a difference. Going from the 2.5L to the 2.0L DI motor was a completely different motor.

  • John Bay Hansen

    Yes the wing look silly. They should have made an automatik wing, that raise at high speed when downforce is needed. Like on a Porche.

  • soul_theorem

    My turbo-swapped ’04 Forester makes more HP than the new ‘stock’ STI. Subaru should have engineered at least 350 HP into the new STI – minimum! A freakin’ 2014 V6 Mustang makes the same 305 HP. Subaru disappoints again….

  • Rainabba

    You sound like every ignorant 15yo kid that just walked out of a NFS movie. HP means nothing if you can’t put it down, control it and steer it. Go test drive a ’15 STi then tell me how you think your comment is relevant. Same to Pablo above who thinks that there have been no “major performance upgrades”. The STI has failed to grab my attention for the better part of the decade it’s been available here in the states. Until the ’15, I would have taken my last AWD car (EVO IX MR) over it any day. “UNTIL the ’15” being the key. This almost shouldn’t be called an STI anymore because it’s no longer squishy and an understeering such-and-such as it’s always been known. Same motor, yes. That’s about where the similarities stop and that’s not a bad thing. It just means that it’s an amazing motor with amazing support and I’m actually quite happy I get a new car packaged up with a well-established motor because now I don’t have to wait 3 more years for real upgrades or solid tunes; they already exist.

    Next wanna-be naysayer up?!

  • soul_theorem

    Well alrighty then, Rainabba… You just go ahead and keep making excuses for your ’15 Sti’s ‘inadequacies’. One more thing: VW just announced a 395hp AWD Golf. Your ’15 Sti has just become even more irrelevant.

    And, doesn’t it just unnerve you that a Blouch TD05-18G equipped ’05 Forester can blow your ’15 Sti’s proverbial doors off? You should be…

  • John STI

    OK dickwad, what’s your point? It’s not a pissing competition. Your pissy Forester would get eaten any day of the week by a 2015 STI (stock vs stock). Who friggin cares what VW just announced? If you don’t like the car, go back to your upgraded soccer mum car and leave the real enthusiasts to enjoy.

  • Pablo

    The STI has had no major performance upgrades for 10 years. It’s a joke. The brand is a joke. The concept car last year was beautiful, and they release this boring car with no significant improvements in any performance category. This is why I also look at it, but never bite when I’m shopping for cars.
