Subaru WRX S4 STI Sport # is a sharper, limited-edition WRX for Japan only

Depending on your nationality, age, and interests, the first association for the # symbol could be pound — for weight or the telephone, number, plain old hash or hashtag, or sharp for the musically inclined. Subaru Japan intends that last meaning for its new WRX S4 STI Sport #, because this is a sharper version of the mass-produced WRX S4 STI Sport introduced to the top of the range last year. Of note, this vehicle is a standard WRX, not a full-beans WRX STI. The differentiator is the "STI Sport" designation, which has also been applied to the Japan-market Levorg and BRZ, representing a model developed with input from Subaru Tecnica International. Last year's flagship trim picked up STI-tuned Bilstein DTMatic II inverted struts at front, STI-tuned conventional springs and dampers in back, 18-inch black wheels to go with black trim pieces like mirror caps and decklid spoiler, and a special interior with Bordeaux leather and ultra suede. Output from the 2.0-liter four-cylinder Boxer motor was left unchanged from the WRX S4 at 296 horsepower and 295 pound-feet of torque, shifting through the automaker's Sport Lineartonic CVT. The sedan costs 4,093,200 yen ($38,050 U.S.). The limited-edition WRX S4 STI Sport # displays a keener edge thanks to three STI components tested on the division's Nurburgring race cars — a flexible front tower bar, and flexible draw stiffeners for front and rear. All three components have been available on the aftermarket for a while, but their stock fitment is apparently new. The flexible tower bar looks like a typical strut tower reinforcement, but a pillow ball joint in its middle provides vertical elasticity. The bar maintains rigidity across the vehicle, but when the suspension needs a little give to work up and down, the pillow ball joint allows that. The flexible draw stiffeners are adjustable rods that connect a longitudinal frame member to a component on the cross-member, increasing chassis stiffness. STI says the three parts deliver faster steering response, reduced roll speed, and improved wheel tracking in the case of road ruts or crosswinds without compromising suspension suppleness. The Boxer sees some tweaks like a freer-breathing air filter and exhaust that raise torque by up to 10%, and sharpen throttle response. Thicker sound insulation in the floor and extra vibration-damping material in the spare tire well cut road noise for all occupants.

Next Subaru WRX and STI to go sedan only; reveal headed for LA

After a serious bit of teasing at the 2013 New York Auto Show, Subaru might be finally preparing to pull the sheets off of the production versions of the new WRX and STI. The venue, according to Automotive News, will be the 2013 Los Angeles Auto Show in November. Besides that tasty bit of info, AN has a number of other interesting ideas about the 2015 WRX.
If you've been a fan of the five-door bodystyle, don't read this - the next WRX and STI will reportedly go four-door only. We've already seen the latter's whopping great wing, a tradition we're happy to see soldering on for next-gen car. According to the AN report, power figures to be around 265 horsepower from a 2.5-liter, turbocharged, flat-four engine.
Los Angeles is still quite far off, so expect to hear more rumblings about a production WRX or STI in the coming weeks. Take a look above for our most recent batch of spy photos, and then hop down below for some images of the stunning WRX Concept that was shown at New York.

2015 Subaru WRX caught testing in US on Mulholland

In April, we got our first glimpse at the 2015 2015 Subaru WRX - the car was caught in STI form in photos and in motion running around Germany's infamous Nürburgring. That's all well and good, but obviously Subaru will sell a good number of the hotter Impreza models here in the United States, and thus, it's nice to now see a video of the next WRX testing out in California, albeit in what looks to be non-STI form.
Originally posted on the Subaru Owners Club website, this video comes from YouTube user 31200MulhollandHwy. And that's quite appropriate, since the video clearly shows the now de-winged WRX prototype testing on the well-known - you guessed it - Mulholland Highway. Just like before, we're disappointed that the prototypes spotted testing don't appear to be as bold and beautiful as the WRX Concept that Subaru brought to this year's New York Auto Show. Nevertheless, we'll hold our final judgments until the camouflage is peeled away.
Have a look below to see (and hear!) the 2015 WRX running up Mulholland.
